PayoutPeek reads your Etsy monthly statement CSV and shows your take-home and a fee breakdown, and also offers an Etsy fee calculator. The page says the CSV is processed in the browser and states that it is not affiliated with Etsy. It is web only and works with no sign-up.
Free is $0 and covers one monthly statement at a time, real take-home, fee breakdown and the top 3 red flags. Pro is $8 per month or $69 per year and adds per-product profit, deposit-by-deposit breakdown, order-level detail, all flags, up to 12 months combined and CSV export. Multi is $14 per month or $119 per year and adds TikTok Shop settlement reports.
PayoutPeek was built to show Etsy sellers where each dollar of a payout went: sales tax, refunds, fees and what they kept.
