Calculate allowable cost before spending
This calculator helps determine the maximum cost per click (CPC) you can afford based on expected conversion rates and payouts. Knowing your allowable CPC is essential before buying traffic, as it defines your bidding limit to maintain profitability.
Include approval rates in your forecast
Not all conversions are paid. Affiliate networks often reject duplicates, fraudulent leads, or invalid traffic. By including an estimated approval rate, your expected EPC and revenue numbers reflect actual paid commissions rather than gross tracked conversions.
Frequently asked questions
How is Earnings Per Click (EPC) calculated?
EPC is calculated by dividing the total expected commission by the number of clicks (traffic). It represents the average revenue generated for every click sent to the offer.
What is allowable CPC?
Allowable CPC is the maximum amount you can pay for a click and still break even. It is calculated by multiplying your conversion rate by your payout (and approval rate, if applicable). Paying less than this amount yields a profit.
