Affiliate Income Calculator
Affiliate income comes down to a simple chain: traffic × conversion × commission. This free tool projects your monthly and annual earnings from those inputs — and, because the best programs pay recurring commissions, it also shows how income compounds when referrals keep paying month after month. No signup.
For one-off commissions, set "months a referral pays" to 1. For recurring programs (like a SaaS that pays you every month the customer stays), set the average number of months they remain — that's where affiliate income really compounds. Commission can be a flat amount or your % of the sale price; just enter the dollars you earn per referral per period.
Why recurring commissions change everything
A one-off commission pays once. A recurring commission pays every month the customer stays — so each referral you make keeps earning while you go find the next one. New referrals stack on top of old ones, and your monthly income climbs toward a steady state of roughly monthly referrals × commission × average retention. That's why creators prize recurring affiliate programs as a daily-income spine.
Recurring affiliate income behaves just like a subscription base — model how it grows month by month with the recurring revenue projector. To build the traffic side, read passive income ideas that actually work and the best tools to start with. A great example of a recurring program is Systeme.io (60% lifetime commissions).
