Free ROI Calculator for Influencer Marketing
Estimated Revenue Impact from Impressions
Fill in the three inputs to calculate estimated revenue.
The formula divides impressions by 7 before applying conversion rate and average order value. This is a Rule of Seven modelling assumption, not measured behaviour.
Return On Investment
Fill in creator payments, product cost, and either Revenue or ROI to calculate the remaining value.
How to calculate influencer marketing ROI
Influencer marketing ROI compares the revenue generated by a creator campaign with the money invested in it. Start by adding the campaign costs included in this calculator: creator payments and product cost. Subtract that investment from campaign revenue to find the return. Then divide the return by the investment and multiply by 100 to express the result as a percentage.
Influencer marketing ROI = ((Revenue - Creator Payments - Product Cost) / (Creator Payments + Product Cost)) x 100
For example, if creator payments are $30,000, product cost is $5,000, and revenue is $100,000, the total investment is $35,000. The return above cost is $65,000. Dividing $65,000 by $35,000 and multiplying by 100 produces an estimated ROI of 185.71%.
The calculator can also work backward. If you enter creator payments, product cost, and a target ROI, it calculates the revenue required to reach that target.
What the impressions estimate assumes
The first step is not an attribution model. It estimates revenue from impressions by dividing total impressions by seven, applying a conversion rate, and multiplying the estimated orders by average order value.
Estimated Revenue = (Impressions / 7) x (Conversion Rate / 100) x Average Order Value
The divide-by-seven step reflects a Rule of Seven assumption: a person may need several exposures before taking action. Here, seven impressions are treated as one potential website visit. That is a modelling assumption rather than measured behaviour. Real people may act after fewer exposures, after more exposures, or not at all.
Because the estimate is built from assumptions, it should be used for scenario planning. It can help you compare inputs or pressure-test a campaign idea, but it should not be reported as revenue that the campaign actually generated.
What counts as a cost
This calculator includes two direct inputs:
- Creator payments: Flat fees, retainers, commissions, or other cash compensation paid to creators.
- Product cost: The brand’s cost of products provided to creators, not the retail value shown to customers.
Those inputs do not capture every campaign expense. Shipping, fulfilment, agency fees, platform costs, paid amplification, production support, and internal labour are not included. If those costs are material, add them to your own campaign analysis before treating the result as a complete ROI figure.
Using consistent cost definitions matters more than making the percentage look large. A useful ROI calculation should make it clear which costs are included, which are excluded, and where the revenue number came from.
Why estimated ROI is not attributed ROI
An impressions model tells you what a campaign might have been worth. Tracked revenue tells you what it actually was. Estimated ROI begins with assumptions about exposure, visits, conversion rate, and order value. Attributed ROI begins with campaign links, discount codes, order data, or another measurement method that connects a purchase to creator activity.
Estimated ROI is useful before a campaign or when tracking is incomplete. It gives a team a common scenario to discuss. Attributed ROI is useful after launch because it reflects recorded behaviour. The two can be compared, but they should not be presented as the same measure.
The free tool checks whether the followers are real. Gia can also tell you whether that creator has ever driven a sale.

What is influencer marketing ROI?
Influencer marketing ROI compares the revenue generated by a creator campaign with the money invested in that campaign. It is usually expressed as a percentage.
How do you calculate influencer marketing ROI?
Add creator payments and product cost, subtract that total investment from campaign revenue, divide the result by the total investment, and multiply by 100.
Why does the impressions estimate divide impressions by seven?
The calculator uses a Rule of Seven modelling assumption. It treats seven impressions as one potential website visit before applying the conversion rate and average order value. This is an estimate, not measured customer behaviour.
What costs are included in this ROI calculator?
The calculator includes creator payments and product cost. It does not include shipping, agency fees, platform costs, internal labour, or other campaign expenses.
Is estimated ROI the same as attributed ROI?
No. Estimated ROI models what a campaign might have been worth. Attributed ROI uses tracked orders and revenue to show what the campaign actually drove.
