Affiliate Commission Calculator

Calculate commission owed on affiliate sales, including tiered rates above a volume threshold.

About Affiliate Commission Calculator

Tiered programmes split sales at the threshold and pay the higher rate only on the excess. Refund clawback then reduces the payable amount, which is why the effective rate sits between the two headline rates. Affiliates model earnings at the top tier while finance accrues at the base rate; computing both bands and the clawback is what reconciles them.

Formula

Affiliate Commission

Commission = sales below threshold × base rate + sales above × tier rate, less refund clawback

clawback: Commission reversed when the underlying order is refunded
