How it works

ROI asks what remained

Revenue is adjusted by gross margin before marketing cost is subtracted.

ROI = (revenue × gross margin − marketing cost) ÷ marketing cost

Worked example

A 100% marketing ROI

$20,000 revenue at 50% gross margin creates $10,000 gross profit. After $5,000 marketing cost, the $5,000 net return equals 100% ROI.

Understand the result

How do you calculate marketing ROI?

Marketing ROI in this calculator is gross profit minus marketing cost, divided by marketing cost, expressed as a percentage. Gross profit is revenue multiplied by gross margin. This approach helps distinguish revenue growth from the money remaining after direct costs and marketing.

How to use this calculator

  1. Enter revenue associated with the marketing activity for your chosen period.
  2. Set the gross margin before marketing expenses.
  3. Include the marketing costs you want to evaluate, then review ROI and net return together.

How to interpret your result

A positive result means gross profit exceeds the included marketing costs. It is not company net profit and does not prove incremental impact. Keep the cost scope consistent, and use a suitable comparison or experiment to assess whether marketing caused the revenue.

Frequently asked questions

Does 100% marketing ROI mean revenue doubled?

No. In this model, 100% ROI means net marketing return equals the marketing cost. With $2,000 gross profit and $1,000 marketing cost, net return is $1,000 and ROI is 100%.

Which marketing costs should I include?

Use the costs relevant to your decision, such as media, creative and agency fees. Do not subtract the same cost twice through both gross margin and marketing cost.
