Your unit gap sets the plan.

Put Car Dealership Marketing ROI Against Your Monthly Goal

When the floor is slow, aged inventory sits and the month falls behind, more leads only help if someone answers them. A Facebook / Meta Sales Event gives your store a focused appointment push. Willowood runs the ads, our live US-based bilingual BDC handles conversations in English and Spanish 24/7/365, and your team handles the sale.

Use the calculators below to decide how many set appointments your goal calls for, whether your floor can handle them, and what additional gross could cover the investment. Replace the examples with your store’s numbers, then forward the assumptions and results to the owner.

“Your appointment plan has to fit your sales goal and your floor.”

How to Use This Dealership Event ROI Calculator

1

Define the gap.

Enter your monthly unit goal and the units you already expect to sell. Start with the business you still need.

2

Check floor capacity.

Use your show and close rates to estimate the appointment load. Check that load against your event days and daily capacity.

3

Check additional gross.

Enter your investment and gross per unit. Discount sales you would likely have made without the event.

4

Review the assumptions.

Book a demo to review inventory, event dates and a set appointment target with Willowood.

Mode A: Gap to goal

This appointment to sale calculator works backward from the units you still need. It assumes the resulting sales fill that gap.

These are editable examples. Replace the unit goal, forecast, rates, event days and capacity with your store’s plan. Capacity means set appointment slots your floor can accept per day.

Mode B: ROI and break-even

Enter your own total event investment. Include all event costs you want this calculation to cover.

This worked example uses editable assumptions: 150 set appointments, a 50% show rate, a 25% show-to-sale rate and $2,800 average front and back gross per unit. Replace these with your numbers. The investment field is intentionally blank.

Enter your own amount. This field contains no Willowood price.
The 70% default is an example. Not every matched sale is new. Enter the share you believe would not happen without the event.

How to Read the Results and Set a Dealership Advertising Budget

Mode A rounds set appointments and required capacity days up. Mode B keeps fractional expected sales in the math and displays estimates to two decimal places. Fractions describe an average outcome, not part of a delivered unit.

Use these formulas when you review the plan.
ResultCalculation and meaning
Set appointments requiredRemaining units divided by (show rate multiplied by show-to-sale rate), rounded up. Rates are converted from percentages.
Additional salesSet appointments multiplied by show rate, show-to-sale rate and additional sales percentage.
Net of investmentGross on additional sales minus total event investment. This is a gross-based estimate, not dealership net profit.
Break-even unitsInvestment divided by average gross per unit, rounded up. These must be additional units, not just sales matched to an ad.
Cost per shown appointmentTotal event investment divided by expected shows. This uses shown appointments, not set appointments.
Maximum investmentGross on additional sales is the maximum investment at gross break-even. To retain gross after investment, subtract the amount you want to retain from that maximum.

Do not copy Mode A’s appointment goal into an ROI forecast without checking the additional sales assumption. Mode A treats sales as filling your gap. Mode B discounts sales that might have happened anyway.

Inventory, desk capacity and follow-up change the math.

Inventory has to fit demand.

Check availability and vehicle mix before you choose a close rate. Aged units still need to fit the buyers who show.

The desk has to handle the load.

Spread appointments across the event and staff the desk for that schedule. A full calendar only helps when your team can work the buyers.

Follow-up has to continue.

Our BDC sets appointments in our proprietary CRM. Use your live login to coordinate the floor and follow up with buyers who still need a decision.

This is one event result.

A Nissan Dealer in Illinois Added 37 Extra Units

The dealer ran a 4-day event.

The event produced 167 set appointments, 37 extra units and $128K in gross. These figures describe one event. They are not the calculator’s expected outcome for your store.

Use your own rates and gross to build your plan. This case does not provide the event investment, so it cannot establish a net ROI figure.

Dealership Event Planning FAQs

How does the dealership event ROI calculator work?
The calculator turns your unit gap into a set appointment requirement, then estimates event gross using your show rate, show-to-sale rate, gross per unit, and additional sales percentage. Enter your own total investment to see the net of investment and break-even units. The editable examples are planning assumptions, not a forecast or a Willowood quote.
How many appointments does a dealership need to hit its unit goal?
Subtract units already forecast from the monthly goal, then divide the remaining units by the show rate multiplied by the show-to-sale rate. Round the result up to a whole set appointment. Mode A also checks the daily appointment load against the capacity you enter. It assumes the resulting sales fill your remaining gap.
How should I measure car dealership marketing ROI?
Start with additional sales, not every sale matched to the campaign. Multiply additional sales by average front and back gross per unit, then subtract the total event investment. Divide that net amount by the investment to calculate ROI. This is a gross-based planning estimate, not dealership net profit.
What show and close rates should I use in an appointment to sale calculator?
Use your own recent appointment show rate and your close rate among buyers who showed. The editable show rate of 50% and show-to-sale rate of 25% are examples to replace. Use lower assumptions when inventory, desk capacity, or follow-up is likely to limit sales.
How do I set a dealership advertising budget for an event?
Use Mode B to estimate gross on additional sales. That gross is the maximum total investment at gross break-even. Set a lower budget if you need a positive return after the investment, and account for costs not covered by your gross estimate. Enter your own total event investment; the calculator does not supply a package price.
Does Willowood promise the sales shown in the calculator?
No. Calculator outputs depend on the assumptions you enter. Every package carries a set appointment target. If we miss it, we keep working at no extra cost until we hit it. Willowood runs the Meta ads, and our live US-based bilingual BDC works 24/7/365 in English and Spanish to set appointments in our proprietary CRM. The dealer gets a live login and sells the cars.
