How to Set a Car Dealership Marketing Budget You Can Defend
A car dealership marketing budget should start with the number of cars you plan to sell, not with last year’s invoices. Build it from the goal backward and every line has a job, a cost and a result you can check at month end.
Start from the unit goal, not from last year
Most budgets are built by taking last year’s spend and adjusting it a little. That method protects old habits and never asks whether each dollar earned its place. Flip the order. Write down the number of new and used units you intend to retail next month. Subtract the sales you can count on without advertising, such as repeat customers, referrals and service drive conversions. What remains is the number of sales marketing has to produce. That is the figure your budget exists to deliver.
Work backward to the traffic you need
Use your own closing numbers to translate sales into activity.
- Sales needed from marketing, divided by your closing rate on shown appointments, equals the shows you need.
- Shows needed, divided by your show rate, equals the appointments you need.
- Appointments needed, divided by your set rate, equals the leads or conversations you need.
Now you know how many conversations the budget must buy. If you do not have clean rates of your own yet, the Willowood BDC benchmarks of a 35% set rate, a 65% show rate and a 15% overall closing rate give you a reference point while you gather a few months of data.
Sort every line into three buckets
Print your current marketing expenses and place each one into a bucket.
- Demand capture. Reaches people already shopping: search ads, inventory listings, your website and your local business profile.
- Demand creation. Reaches people before they start shopping: social media campaigns, video, sales events and direct outreach to your database.
- Overhead. Tools and fees that do not reach a customer by themselves: software, reporting packages, agency retainers.
A healthy budget has money in the first two buckets and a lean third bucket. If overhead has crept up to rival what you spend reaching customers, that is the first place to look for savings.
Give each line one number to hit
Next to every expense, write the single result it is responsible for and who reports on it. For a lead source, that is appointments set and cars sold. For a retention tool, it is repeat visits. If nobody can name the number, or the vendor can only report clicks and impressions, mark the line for review. A budget you can defend is one where every row has a result attached that a manager can verify in your CRM.
Hold back a test fund
Set aside a small, fixed share of the monthly budget for trying one new thing at a time. Give each test a clear start, a clear end and a pass or fail mark agreed in advance. This keeps experiments from quietly becoming permanent costs, and it keeps the store from standing still while the market changes around it. When a test passes, it earns a place in the core budget and something weaker comes out.
Review monthly and move money quickly
Hold a thirty minute budget review after each month closes. For every source, look at spend, appointments, shows, sold units and cost per sold unit. Move money from the bottom of the list to the top. Small monthly shifts are easier and safer than one large overhaul a year, and they stop a weak source from draining twelve months of spend before anyone notices. Favor partners who agree to be measured this way and who put a commitment, such as a set appointment minimum, in writing.
Frequently asked questions
Should the marketing budget be a percentage of gross?
A percentage is a useful ceiling, but it does not tell you where to spend. Build the budget from the unit goal first, then check it against the percentage you are comfortable with.
How should a store split new and used advertising?
Follow your inventory and your margins. Put more behind the department with cars to sell and room to grow, and revisit the split each month.
What should be cut first when the budget is tight?
Cut the lines that cannot be tied to appointments or sales. Protect the sources with the lowest cost per sold unit.
