Market share measures the percentage of new vehicle sales captured within a defined market during a given month.
In Maven, you’ll see two types of market share:
These metrics provide the foundation for evaluating dealership performance throughout Maven.
Understanding the difference between these markets is important when interpreting your results.
| Term | Definition | Used for |
| Local Market Area (LMA) | Your dealership’s core sales footprint and primary competitive market, where 80+% of new vehicle sales exist. | Dealership market share |
| Designated Market Area (DMA) | A larger media market defined by Nielsen that includes multiple cities and dealerships. | Brand market share |
Dealership market share and brand market share are not designed to equal one another. Dealership market share compares one store’s sales against the total market in its LMA, while brand market share compares all franchise stores for that brand against the total market in the DMA. Because they use different comparison groups and geographies, the percentages are not directly comparable.
Market share is calculated using DMV vehicle registration data provided by Experian.
EMG performs additional cleansing, normalization, and validation processes to improve consistency and maintain accurate reporting across all markets.
Each metric provides a different perspective.
Together, these metrics provide the context needed to determine whether changes in dealership market share reflect dealership-specific performance or broader OEM trends across the region. This makes it possible to evaluate how your dealership is performing relative to other same-brand dealerships—not just whether your isolated market share increased or decreased.

Can dealership market share and brand market share be compared directly?
No. Each metric is calculated using a different geographic market and denominator. Instead of comparing the percentages themselves, compare how they change over time.
Can I customize my Local Market Area?
No. Our system calculates market share using the dealership’s unique, predefined Local Market Area.
What data source is used?
Market share is calculated using new vehicle registration data from Experian.
How accurate is the data?
While DMV registration data can contain small reporting delays, these have minimal impact on percentage-based metrics like market share. EMG also performs additional validation and normalization before reporting.
