Read the result correctly
Contribution per sale is the average sale price after modeled refunds, platform fees, and per-sale costs. The monthly result multiplies contribution by sales and subtracts fixed costs. Break-even sales round up the number needed to cover those fixed costs. A negative contribution means more sales increase the modeled loss.
Refund assumptions
The model assumes refunded sales are fully refunded at the average price. The refund rate is an expected percentage, so it can represent a fraction of a sale. Fee treatment follows the option you select. The model does not infer any platform’s refund policy.
Profit is different from available cash
Payout holds, minimum withdrawals, tax, chargeback penalties, currency conversion, and unentered expenses are excluded. Add relevant costs to the inputs and check withdrawal timing separately. Your inputs stay in this page; this tool does not store or send them.
Compare the documented platform fees before choosing your inputs.
