About Influencer Campaign ROI

Runs follower count through engagement, click and conversion rates to reach orders, then values them at average order value and gross margin. Because the three rates multiply, the model shows why a large follower count with weak engagement performs worse than a smaller, genuinely engaged audience.

Formulas

Orders

Orders = followers x engagement rate x click rate x conversion rate

Return on spend

ROAS = attributed revenue / (fee + gifted product cost)

Assumptions and limits

The result is derived only from the 8 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Is engagement rate a reliable predictor?

Only loosely. Saves, shares and comments correlate with purchase intent far better than likes, and audience-brand fit outweighs the raw rate.

Should gifted product be counted at cost or retail?

At cost, since that is the cash you actually forgo. Counting it at retail overstates the campaign spend and understates ROAS.
