Radio advertising for car dealerships is a documented, measurable channel with a clear track record across spend data, ROI studies, and dealership-specific case results. While digital platforms capture the largest share of dealer budgets, broadcast and streaming audio continue to deliver returns that hold up under econometric scrutiny, particularly for local market penetration and sales event promotion.
The data below draws from NADA financial profiles, Radiocentre econometric analyses, Zimmer Communications ROI research, and dealership-specific campaign results. For a marketing director evaluating channel allocation, these numbers answer the core questions: what dealers actually spend on radio, what they get back, and how radio interacts with the digital channels that dominate the modern car-buying journey.
Key Takeaways
- The average new car dealership spent $50,248 on radio in 2023, up from $39,730 in 2022, a year-over-year increase of more than 26% (NADA via InsideRadio).
- Radio sits just below television in per-dealership spend, with the average dealer investing $52,892 in TV versus $50,248 in radio in 2023.
- Brands see an average sales lift of over $6 for every $1 spent on radio, which Zimmer Communications describes as double the ROI of top-performing digital and TV campaigns.
- Within 24 hours of hearing a radio ad, 78% of listeners take a digital action, including visiting the brand’s website, checking its social page, or searching for it online.
- Radio drives a 29% incremental lift in branded online search, making it a direct amplifier for dealership SEM campaigns.
- A family-owned dealership running a $7,500 per month radio campaign averaged 40 used vehicle purchases per month, generating over $1.1 million in additional profits.
- Local dealership radio campaigns promoting sales events typically generate 3 to 5x ROAS, with CPMs ranging from $5 to $12 depending on market size (Willowood Ventures).
Radio Advertising Reach and Listenership
Radio reach for car dealerships is a local market story. The medium’s value is not national scale; it is the ability to build consistent frequency with a defined trading area population at a cost structure that most digital awareness channels cannot match.
1. Roughly half of a local market’s population listens to broadcast radio each week
Local broadcast radio reaches approximately 50% of a city’s population each week, making half the trading area accessible through the medium on a regular basis (DealerCreative).
For a dealership, that weekly reach figure defines the realistic ceiling for radio’s awareness contribution. One in two local consumers is reachable through the channel every week, which positions radio as a scalable option for brand awareness and event promotion in markets where digital fragmentation makes comparable reach expensive.
2. Sustained 52-week radio schedules can reach up to half a local market’s population with consistent frequency
Year-round radio campaigns, run at consistent frequency, can own the hearts and minds of up to half the people in a community, according to DealerCreative’s analysis of dealership radio strategy.
The mechanism here is involuntary recall: repeated exposure over 52 weeks builds the kind of top-of-mind awareness that activates at the moment a consumer decides to shop for a vehicle. In a high-consideration category where purchase timing is unpredictable, that sustained mental availability matters more than a single high-reach burst.
3. A 3x weekly frequency schedule costs between $0.14 and $0.72 per person per year depending on market size
Reaching the same listener three times per week for a full year costs between 14 cents and 72 cents per person annually, based on 2016 market benchmarks from DealerCreative.
That cost structure makes radio one of the most efficient channels for sustained brand recall. Even at the high end of that range, a dealership covering a market of 100,000 weekly listeners would spend under $72,000 to maintain 3x weekly frequency for an entire year, a figure that compares favorably to the cost of equivalent digital awareness reach across fragmented programmatic inventory.
Car Dealership Marketing Spend
NADA’s annual financial profiles provide the most reliable benchmarks for how dealers actually allocate advertising budgets across channels. The data below covers both the 2023 snapshot and the 2018 baseline, giving a five-year frame of reference for radio’s position in the mix.
4. The average new car dealership spent $528,923 on advertising in 2023
Total advertising expenditure per dealership reached $528,923 in 2023, according to NADA data reported by InsideRadio.
At that budget scale, every channel in the mix is a meaningful dollar commitment. Radio’s $50,248 share represents roughly 9.5% of total spend, a figure that is neither trivial nor dominant. It sits in the range where optimization decisions, including frequency adjustments, market selection, and creative strategy, can produce measurable swings in per-unit advertising cost.
5. Radio’s share of the average dealership ad budget rose to $50,248 in 2023, up from $39,730 in 2022
The year-over-year increase in dealer radio spend from $39,730 to $50,248 represents a 26% jump in a single year (NADA via InsideRadio).
That increase is notable because it runs counter to the narrative that radio is in structural decline as a dealership channel. Dealers are actively reallocating budget back toward the medium, likely in response to rising digital CPMs and the documented cross-channel amplification effects that radio produces on search and website traffic.
6. Local car dealerships combined spent $8.9 billion on advertising in 2023, a $330 million increase from 2022
The total U.S. local dealer ad market reached $8.9 billion in 2023, up $330 million from the prior year, according to NADA data reported by InsideRadio.
Radio’s share of that national figure reflects a channel that is growing in absolute terms even as the overall budget pie expands. For radio stations and media buyers working with automotive clients, the expanding total market creates room to capture incremental dollars without requiring dealers to cut other channels.
7. The average advertising cost per new vehicle sold was $708 in 2023
Dealers spent an average of $708 on advertising for each new vehicle sold in 2023, according to NADA data reported by InsideRadio.
This per-unit benchmark is the most practical way to evaluate any channel’s contribution. Radio’s relatively low CPM means it can deliver brand awareness and event response without inflating per-unit costs, but only when attribution infrastructure is in place to connect radio exposure to actual vehicle sales.
8. Radio captured 10.1% of all local dealer ad dollars in 2018, totaling $942 million nationally
In 2018, one in ten local car dealer ad dollars went to radio, with the channel capturing $942 million of the $9.42 billion total dealer ad market (InsideRadio).
That 10% share figure provides a useful historical baseline. The 2023 data showing $50,248 per dealer out of $528,923 total represents roughly the same proportional commitment, suggesting radio has maintained its structural position in the dealer mix even as digital channels have grown.
9. The average dealership spent $56,820 on radio out of a total $562,575 advertising budget in 2018
Radio’s per-dealership investment in 2018 reached $56,820 out of a total budget of $562,575, according to NADA data reported by InsideRadio.
The 2018 figure is actually higher than the 2023 average of $50,248, which reflects the broader budget compression that followed the pandemic years. The 2022-to-2023 rebound suggests dealers are rebuilding radio investment toward pre-pandemic levels, though total budgets have also shifted with the growth of digital categories.
10. The per-unit advertising cost in 2018 was $624, down $5 from 2017
Dealer advertising efficiency improved slightly in 2018, with the cost per new vehicle sold falling to $624 from $629 the prior year, according to NADA senior economist Patrick Manzi via InsideRadio.
Year-over-year efficiency gains of this magnitude reflect ongoing channel mix optimization. Radio’s low CPM relative to television and premium digital placements contributes to keeping per-unit costs in check when the channel is sized appropriately within the overall budget.
11. Radio ranks just below television in per-dealership spend, with TV at $52,892 and radio at $50,248 in 2023
The channel-level breakdown shows radio at $50,248 and television at $52,892 per dealership in 2023, based on NADA data summarized by Ritner Digital. Both trail digital categories including third-party listings ($109,000), SEM ($105,000), SEO ($103,000), and social media ($64,000).
Radio’s proximity to television spend is significant. The two channels are nearly equal in per-dealership investment, yet radio’s CPM is typically lower, which means dealers are getting more impressions per dollar from radio than from TV. The gap between radio and the leading digital categories reflects where performance attribution is clearest, not necessarily where reach efficiency is highest.
ROI and Conversion Metrics
The ROI case for radio advertising in automotive is supported by multiple independent studies using econometric methods. The figures below span Zimmer Communications’ cross-medium analysis, Radiocentre’s large-scale econometric modeling, and dealership-specific campaign results.
12. Brands see an average sales lift of over $6 for every $1 spent on radio advertising
Radio advertising delivers an average sales lift exceeding $6 per $1 spent, which Zimmer Communications describes as double the ROI of even the best results from digital and TV campaigns.
For a dealership investing the typical $50,000 annually in radio, a 6:1 return implies $300,000 in attributable sales from the channel. That figure is directional rather than guaranteed, but it establishes a performance floor that makes radio competitive with the ROAS benchmarks dealers use to evaluate digital channels.
13. Radiocentre’s econometric analysis across 464 brands found an average return of £7.70 for every £1 spent on radio
Across 464 radio-advertised brands, the average radio ROI reached £7.70 per £1 spent, based on Holmes and Cook econometric modeling commissioned by Radiocentre.
The methodology here is worth noting. Econometric analysis isolates radio’s contribution to sales by controlling for other marketing variables, pricing changes, and seasonal effects. A 7.7:1 return derived through that method is more defensible than a simple correlation between ad spend and sales volume. The figure aligns closely with Zimmer’s 6:1 benchmark, giving the range credibility across two independent research programs.
14. A separate Radiocentre study across 42 campaigns found an average radio ROI of £6.00
The average return across 42 radio campaigns was £6.00 per £1 spent, with automotive brands showing a 35% increase in likelihood to browse advertised brands among exposed listeners (Radiocentre).
The automotive-specific behavioral finding is the more actionable number for dealerships. A 35% lift in browsing intent among exposed listeners means radio is not just building passive awareness; it is actively moving consumers into the research phase where digital channels can engage and convert them.
15. Local dealership radio campaigns promoting sales events typically generate 3 to 5x ROAS, with CPMs ranging from $5 to $12
Event-driven dealer radio campaigns typically produce 3 to 5x return on ad spend, with cost per thousand impressions ranging from $5 to $12 depending on market size, according to Willowood Ventures.
The CPM range is particularly useful for budget planning. At $5 to $12 CPM, radio is competitive with many programmatic display buys, especially in mid-size markets where digital inventory costs are higher relative to reach. The 3 to 5x ROAS floor gives marketing directors a realistic performance target to set before a campaign launches rather than evaluating results after the fact.
16. A $7,500 per month radio campaign at one dealership produced 40 used vehicle purchases per month and over $1.1 million in additional profits
One family-owned dealership running a local radio campaign to solicit consumer vehicle purchases averaged 40 used cars per month at an average profit of $5,000 per vehicle, generating over $1.1 million in additional profits from the radio investment (InsideRadio).
The math on this case study is straightforward: $7,500 per month in radio spend produced $200,000 per month in gross profit, a return ratio that most digital channels would struggle to match at the same budget level. The campaign’s focus on vehicle acquisition rather than sales promotion is also notable; it demonstrates that radio’s application in automotive extends beyond the standard new-car event model.
Demographic Targeting Effectiveness
Radio’s demographic utility for automotive advertisers is tied to its local reach characteristics and the behavioral data connecting audio exposure to purchase-stage activity.
17. Automotive brands see a 35% increase in likelihood to browse among listeners exposed to radio campaigns
Listeners exposed to automotive radio campaigns are 35% more likely to browse the advertised brands afterward, according to Radiocentre’s Radiogauge effectiveness research.
That behavioral shift, from passive listener to active researcher, is the mechanism that connects radio spend to downstream digital activity. For dealerships running full-funnel campaigns, this browsing lift is the entry point into the digital conversion sequence: VDP visits, lead form submissions, and retargeting sequences that follow the shopper through the remainder of their research process.
Local Market Performance
Radio’s local market characteristics make it structurally well-suited to dealership advertising, where the relevant audience is defined by geography rather than national demographics.
18. Broadcast radio reaches approximately 50% of a local market weekly, making it one of the broadest local reach channels available
Half of a city’s population is reachable through broadcast radio each week, positioning the medium as one of the most scalable local awareness channels for dealerships operating within defined trading areas (DealerCreative).
The local specificity of radio reach is its primary structural advantage over national digital channels. A dealership in a mid-size market does not need national reach; it needs consistent, cost-efficient exposure within a 20 to 30-mile radius. Radio’s geographic concentration delivers that without the waste inherent in broad programmatic buys that extend beyond the dealership’s realistic service area.
19. Sustained year-round radio schedules build involuntary brand recall with up to half of a local market
Year-round radio campaigns at consistent frequency can build automatic brand recall with up to half a local market, according to DealerCreative’s analysis of dealership radio strategy.
The distinction between involuntary recall and active consideration matters in automotive. Most consumers are not actively shopping for a vehicle at any given moment, but they will be at some point. Radio’s ability to embed a dealership name and offer into passive memory means the brand is present at the moment a purchase decision begins, before the consumer has opened a browser or visited a third-party listing site.
Audio Ad Engagement Rates
The engagement data for radio advertising in automotive contexts centers on the cross-channel behavior that audio exposure triggers, particularly the speed and consistency with which radio listeners move to digital platforms after hearing a spot.
20. Within 24 hours of hearing a radio ad, 78% of listeners visit the brand’s website, Facebook page, or search for the brand online
Nearly four out of five radio listeners take a digital action within 24 hours of hearing an advertisement, according to Zimmer Communications’ radio ROI research.
For dealerships, this 24-hour window is the critical conversion period. A radio spot that airs during a morning commute should be supported by active retargeting, live inventory pages, and responsive lead capture by the time the listener reaches a device. The 78% figure means radio is not a passive awareness channel; it is a near-real-time driver of digital intent that requires digital infrastructure to be ready to receive the resulting traffic.
21. People are 6 times more likely to visit a brand’s website after hearing a radio advertisement
Radio exposure multiplies website visit propensity by a factor of six compared to non-exposed consumers, according to Zimmer Communications.
The practical implication for dealerships is that radio and digital are not competing channels; they are sequential ones. Radio generates the intent, and the website captures it. Dealerships whose VDP pages, inventory search tools, and lead forms are optimized will extract more value from this multiplier than those whose digital presence is weak, regardless of how well the radio creative performs.
22. Radio drives a 29% incremental lift in brand online search results
Advertising on radio produces a 29% incremental lift in branded search volume, according to Zimmer Communications’ cross-medium research.
This search lift is one of the most measurable downstream effects of radio spend. Dealerships can track branded query volume in Google Search Console before, during, and after radio campaigns to verify the effect in their own markets. When the lift is confirmed, it also justifies increasing paid search budgets during active radio periods to capture the incremental intent that radio generates.
Competitive Landscape and Market Share
The competitive context for radio in the dealership channel mix is defined by its relationship to digital categories that have grown significantly over the past decade. The data below shows where radio stands relative to other channels and how its share has evolved.
23. Radio ranked as the second-largest traditional media investment for the average dealership in 2023, trailing only television by $2,644
The gap between television at $52,892 and radio at $50,248 per dealership in 2023 is narrow enough that the two channels are effectively at parity in terms of budget commitment, based on NADA data summarized by Ritner Digital.
That near-parity is meaningful context for budget allocation decisions. Television has historically been the dominant traditional medium for automotive advertising, but the data shows radio has closed the gap to within 5% of TV spend per dealership. For marketing directors weighing traditional channel investment, the two channels are now competing for essentially the same budget tier.
24. Radio’s share of local dealer ad budgets has held near 10% from 2018 through 2023
Radio captured 10.1% of local dealer ad budgets in 2018 and approximately 9.5% in 2023, indicating the channel has maintained a consistent structural position in the dealer mix despite the growth of digital categories (InsideRadio).
The stability of that share over five years, across a period when digital advertising grew substantially, suggests radio is not being displaced by digital so much as coexisting with it. Dealers who have maintained radio investment appear to be adding digital channels on top of existing radio budgets rather than substituting one for the other.
25. The total local dealer ad market grew from $8.57 billion in 2022 to $8.9 billion in 2023, with radio’s per-dealer share increasing faster than the overall market
Radio’s per-dealer spend grew by more than 26% year-over-year while total dealer ad spend grew by approximately 4%, meaning radio outpaced the overall market by a significant margin in 2023 (NADA via InsideRadio).
That differential growth rate is the clearest signal in the data that dealers are actively choosing to reinvest in radio rather than simply maintaining legacy commitments. A channel growing at 26% when the overall market grows at 4% is gaining share, not losing it.
What the Data Means for Dealership Marketing Strategy
The 25 statistics above point to a consistent set of strategic conclusions for marketing directors evaluating radio’s role in the channel mix.
Radio is a search amplifier, not a standalone channel. The 29% branded search lift from radio exposure means SEM campaigns should be sized to capture the incremental query volume that radio generates. Dealers who run radio without adjusting their paid search budgets during active campaign periods are leaving conversions on the table. The two channels work in sequence: radio creates the intent, and search captures it.
The 24-hour digital action window requires infrastructure to be ready before the first spot airs. Since 78% of radio listeners take a digital action within 24 hours of exposure, the retargeting sequences, dynamic inventory ads, and lead capture forms need to be active before the campaign launches. A radio spot that drives a surge of website visits to a poorly optimized VDP page or a dealership site without active retargeting loses most of the value the audio impression generated. Demand Local’s omnichannel platform ensures that visitors arriving from radio-driven search or direct site visits enter a retargeting sequence across Facebook dynamic ads, display, and connected TV, keeping inventory in front of shoppers through the remainder of their research process.
Event-driven radio campaigns should be planned against a 3x ROAS floor. The Willowood Ventures benchmark of 3 to 5x ROAS for sales event promotions gives marketing directors a realistic performance target to set before committing budget. At $5 to $12 CPM, radio event campaigns are cost-competitive with programmatic display in most mid-size markets. The discipline is in measuring actual vehicle sales attributed to the campaign period, not just impressions or website traffic spikes.
The $708 per-unit advertising cost benchmark should anchor every channel evaluation. Every channel in the dealer mix should be evaluated against what it costs per vehicle sold. Radio’s documented 6:1 sales lift and low CPM make it competitive on this metric, but only when attribution connects the spend to the sale. Dealers without sales matchback reporting cannot verify radio’s contribution to per-unit cost, which makes the channel appear less accountable than digital channels where click-to-lead attribution is easier to track.
Year-round frequency outperforms burst campaigns for brand recall. The DealerCreative data on 52-week schedules and the Radiocentre findings on sustained brand recall both point to the same conclusion: radio builds mental availability over time. A dealership that runs radio only during sales events misses the compounding effect of consistent frequency on top-of-mind awareness. In a category where the average consumer buys a vehicle every several years, the dealer that is present in passive memory at the moment of decision has a structural advantage over one that only appears during promotional windows.
Radio’s 26% year-over-year spend increase signals a broader reallocation trend. The gap between radio’s 26% growth rate and the overall dealer ad market’s 4% growth rate in 2023 suggests dealers are actively choosing to reinvest in the channel. That reallocation is likely driven by rising digital CPMs, increased competition for search and social inventory, and growing recognition of radio’s cross-channel amplification effects. Marketing directors who have deprioritized radio in recent years may be operating against the direction the data is pointing.

In 2018, the average per-dealer radio investment was $56,820, representing 10.1% of total ad spend.
What is the ROI of radio advertising for car dealerships?
Zimmer Communications’ research reports an average sales lift of over $6 for every $1 spent on radio, described as double the ROI of top-performing digital and TV campaigns. Radiocentre’s econometric analysis across 464 brands found an average return of £7.70 per £1 spent. For event-driven dealership promotions specifically, Willowood Ventures cites a 3 to 5x ROAS range with CPMs between $5 and $12.
Does radio advertising increase website traffic for car dealerships?
Yes. Zimmer Communications’ research shows that people are 6 times more likely to visit a brand’s website after hearing a radio ad, and 78% of radio listeners take a digital action within 24 hours of exposure. Radio also drives a 29% incremental lift in branded online search, which means dealerships should expect measurable increases in both direct website visits and branded search queries during active radio campaigns.
How does radio advertising fit into an omnichannel dealership strategy?
Radio functions as a top-of-funnel reach and awareness channel that drives measurable downstream digital activity. When paired with retargeting, dynamic inventory ads, and paid search, radio exposure converts into trackable website visits, lead form submissions, and vehicle sales. Dealers using a full-funnel approach can attribute radio’s contribution through sales matchback reporting that connects broadcast impressions to closed deals.
Is radio still worth the investment for car dealerships in 2026?
The NADA data shows dealership radio spend increased by more than 26% from 2022 to 2023, outpacing overall dealer ad market growth of approximately 4%. Combined with documented ROI in the 6 to 8x range and radio’s proven ability to amplify digital performance through branded search lift and website traffic increases, the channel remains a viable component of a balanced dealership marketing mix, particularly for local market penetration and sales event promotion.
How does radio compare to television for dealership advertising?
In 2023, the average dealership spent $52,892 on television and $50,248 on radio, a gap of less than $3,000 per year. The two channels are effectively at parity in terms of budget commitment. Radio’s CPM is typically lower than television, meaning dealers generally receive more impressions per dollar from radio, though television carries advantages in visual creative and premium content adjacency.
