Influencer marketing ROI calculator
Model the full campaign economics—not only creator fees—and share the scenario with your team.
Formulas
Campaign profit = attributed revenue − total campaign cost.
ROAS = attributed revenue ÷ total campaign cost.
ROI = campaign profit ÷ total campaign cost × 100.
The model treats the cost inputs as campaign-specific costs. If product cost is already removed from the revenue figure you use, do not subtract it twice. Apply the same attribution and date window to revenue and costs.
Include adjustments
Recalculate after cancellations, returns, and chargebacks. Consider separate scenarios for conservative, expected, and optimistic attribution. ROAS is useful for channel comparison, while ROI exposes whether the campaign produced profit under the cost assumptions entered.
What the calculator cannot decide
It does not estimate untracked influence, future repeat purchases, content licensing value, or brand lift. Report those separately instead of forcing uncertain values into a single precise number.
