How to use the calculator

2

The commission per sale and what you keep update as you type, with the whole program's return in the calculator below.

One-time or recurring commissions?

For one-time purchases the commission is a single payout, so the main question is what rate still leaves margin after acquisition costs. On subscriptions, many programs pay the commission monthly for as long as the customer stays, so the real cost is the rate multiplied by the months a customer keeps paying.

The recurring mode makes that visible. Enter the monthly fee, the commission rate, and a realistic customer lifespan in months, and compare the total commission against lifetime value before locking in a rate.

Frequently asked questions

The payment an affiliate earns for each customer or sale they send you. It's usually a percentage of the sale, though flat amounts per customer are common for services and subscriptions.
Set a flat amount per sale or a percentage of it. Percentages apply to the sale amount, once or per month for subscriptions. There's also a mode that suggests a commission from customer lifetime value, which is revenue per customer minus acquisition cost.
An affiliate earns a single commission for each sale. Referral programs often reward two people, the member who shared and the new customer who joined, so their cost per customer adds both. Each calculator handles its own model.
That's a program design choice. Some programs pay for a fixed number of months, others for the life of the customer. The recurring mode lets you test both by changing the months field and watching the total cost.
