How to calculate affiliate commission
The basic affiliate commission formula is:
For example, if your referred sales total $5,000 and the affiliate program pays an 8% commission, your gross commission is $400. If 5% of those sales are later refunded, the adjusted commission becomes $380.
The total value of purchases attributed to your affiliate links.
The percentage of eligible sales paid by the affiliate program.
The share of sales reversed, cancelled, or excluded from commission.
