Prompt Marketplace Earnings Formula

PromptBase-style marketplaces take a flat commission on every prompt sale and pay sellers the remainder, minus optional early-withdrawal fees if you cash out before reaching the minimum payout balance.

Gross Monthly Revenue = Price per Prompt × Prompts Sold per Month
Platform Fee = Gross Monthly Revenue × Commission Rate
Net Monthly Earnings = Gross Monthly Revenue − Platform Fee − Early Withdrawal Fee (if applicable)
Net Annual Earnings = Net Monthly Earnings × 12
Avg. Net Earnings per Prompt = Net Monthly Earnings ÷ Prompts Sold per Month

PromptBase's standard commission is 20% (sellers keep 80%). Custom prompt jobs are charged a lower 10% fee, and sales made through your referral link can be 0% fee. New sellers are capped at a $4.99 listing price until they build a sales history; established sellers commonly price between $2.99 and $9.99. Payouts require a $30 minimum balance — cashing out earlier incurs a $3.99 fee.
