Use attributable sales and your own contribution figures. The tool does not estimate which campaign caused a sale.

For informational use only. ROI estimates depend on your attribution and gross-profit assumptions and do not predict or guarantee future results. Verify your data and include relevant costs before making a budget decision. This tool does not provide financial advice.

How to use this tool

  1. 1Enter each channel’s spend, leads, and attributed sales.
  2. 2Use contribution per sold vehicle after direct vehicle costs.
  3. 3Compare channels and export the results.

How the result is built

Marketing ROI = (attributed sales × contribution per sale − ad spend) ÷ ad spend. This is a contribution model, not revenue ROAS. Zero spend is shown as not applicable.

An example from the lot

A $1,000 campaign producing two sales at $2,000 contribution each returns $3,000 after advertising, or 300% modeled ROI.
