Referral Program Revenue Calculator

What does the referral program revenue calculator do? It projects the economics of a referral program from four assumptions you enter — how many invitations a typical participant sends, what share of invitees complete the desired action, the average value of a new customer, and what each reward costs — and returns projected new customers, an illustrative viral coefficient, and the implied cost per acquired customer.

How do you compare referral economics against paid acquisition?

Compare the implied cost per acquired customer against what the same customer costs through paid channels. That comparison is often where referral programs prove their worth, since referred customers also tend to stay longer. Run several assumption sets — a cautious one and an optimistic one — and see how much the answer moves.

What does the viral coefficient mean here?

It is the simple product of invitations sent per participant and the share of invitees who convert. Above 1, each cohort more than replaces itself; below 1, the program still acquires customers but needs seeding. Treat it as an illustrative summary of your assumptions, not a measured growth rate.

How reliable are the projections?

Every number here is illustrative, not a promise. Real outcomes depend on the audience, the attractiveness of the offer, how rewards are disclosed, and safeguards against abuse. Use the calculator to sanity-check assumptions, then validate with a small, clearly disclosed pilot before committing budget.
