Work out what one handmade item really costs you: materials from your pack prices, your time at your hourly rate, and a share of your monthly overheads. Then get a wholesale price, a retail price and the lowest online price that still hits your profit margin after platform fees. Works for candles, soap, jewelry, resin, crochet and knitting, baking, stickers and prints, in any currency. Free, no sign-up, nothing is stored.
