Affiliate Commission and Net Payout Calculator
How to Estimate Affiliate Commission
Use eligible sales and reversal figures from the same program, currency, and reporting period.
Enter gross sales that qualify for commission.
Start with program-defined eligibility
Do not enter all referred revenue unless the affiliate agreement treats it as eligible commissionable sales.
What the Commission Estimate Includes
The calculator subtracts entered reversals before applying one flat percentage rate. It then adds one fixed bonus and compares total commission with net eligible sales. It does not model tiered rates, category-specific rates, caps, minimum thresholds, multi-touch attribution, or delayed validation.
Affiliate Payout Examples
Sales with reversals and bonus
Eligible sales and program terms
Estimated commission
Net eligible sales are 9,000. Percentage commission is 720, and the 50 bonus produces an effective rate of about 8.56%.
Bonus without eligible sales
Eligible sales and program terms
Estimated commission
The percentage component is zero. Effective rate is undefined because net eligible sales are zero.
Reconcile against statements
Compare the estimate with the network statement and investigate differences in eligibility, reversals, tiers, or attribution.

The payout arithmetic is a contract-input model. Program terms determine which sales, reversals, rates, and bonuses belong in the calculation.
Formula
Net eligible sales
net eligible sales = gross eligible sales − reversed sales
Total commission
commission = net eligible sales × rate ÷ 100 + fixed bonus
Effective commission rate
effective rate = total commission ÷ net eligible sales × 100
Scientific Background
The model is deterministic and currency-neutral. It does not infer legal disclosure requirements; in the United States, the FTC says material affiliate relationships should be disclosed clearly and conspicuously.
