Affiliate Earnings Calculator

How it is calculated

Earnings follow a three-step funnel: sales = clicks × conversion% / 100, then earnings = sales × commission per sale, and finally EPC = earnings / clicks, the earnings per click. Clicks are the visits sent to the merchant, conversion is the percentage of those clicks that end in a paid sale, and commission is what you receive for one sale. Sales can be fractional because this is an expected value, not a count. Clicks must be above zero, conversion must be between 0 and 100, and commission cannot be negative; anything outside those limits shows no result. A conversion of exactly 0 is allowed and gives zero earnings. The tool counts one commission per sale and ignores recurring commissions, refunds, cancellations and tax.

Common mistakes

• Entering the conversion rate as a fraction (0.024) instead of a percentage (2.4). It is read as 0.024%, giving 1.2 sales instead of 120.
• Using page views or sessions instead of clicks on the affiliate link. Only the visitors who actually reached the merchant count as clicks.
• Using the merchant's gross sale value instead of your commission. The field is what you are paid per sale, not the product price.
• Ignoring returns and cancelled orders. The result is gross commission, and a merchant may reverse commission on refunded sales, so the real payout is lower.
• Entering a conversion above 100, for example 250 for a 2.5% rate by mistake. The tool shows no result because a share of clicks cannot exceed 100%.
