Referral Bonus Calculator

About this calculator

This calculator computes total earnings from a tiered referral program, where the bonus paid per referral increases once you cross a milestone count — for example, $20 per referral for the first 10, then $30 per referral after that. The total is calculated by applying the base rate to referrals up to the threshold and the higher rate to referrals beyond it, then summing both amounts, similar to how progressive tax brackets or tiered commission structures work.

Referral marketing programs — common in SaaS products, fintech apps, gig-economy platforms, and affiliate marketing — use tiered bonus structures specifically to reward and retain their most active referrers, since a flat per-referral rate does not create as strong an incentive to keep referring once someone reaches a high count. Growth and marketing teams also use this tiered math when designing referral program economics, modeling what payout structure drives the most volume within a target cost-per-acquisition.

This calculator takes your total number of referrals, the milestone count, and the bonus rate before and after that milestone, then returns your total earnings broken down by tier, so you can see exactly how much your referrals are worth.
