About Influencer ROI Calculator

Return on ad spend measures revenue against cost while return on investment measures profit, and the gap between them is entirely gross margin. A three-times return on spend loses money at a 30% margin.

Formula

Campaign returns

ROAS = revenue / cost; ROI = (revenue × gross margin - cost) / cost

Frequently Asked Questions

Why can a high return on spend still lose money?

Because revenue is not profit. Below the break-even return the campaign destroys value however good the headline looks.

How reliable is attribution here?

Influencer traffic is often dark — measure with holdout regions or promo codes rather than trusting last-click data.
