About Tagzinho

Tagzinho is a free pricing calculator for people who make things at home and sell them: cakes and sweets, crochet, candles, 3D prints and jewelry.

Tagzinho started in 2026 to take the guesswork out of pricing for small makers. Many people price by copying a competitor or adding a little to the cost of materials. That usually leaves out their own time, the bills that keep the kitchen or workshop running, and the cut a marketplace takes. Tagzinho puts all of that in one place.

How Tagzinho works out a price

Each ingredient or material costs the share of its pack you use. Your time is paid at the hourly rate you choose. A share of your monthly fixed costs, like gas, electricity and your phone, goes into every unit.

Then Tagzinho works the price backwards. When a marketplace takes a percentage and a fixed fee from each sale, the price has to pay that fee too. Tagzinho finds the price that still leaves you your profit margin after the fee. Automated tests check the maths, and every example in the guides comes from the calculator itself.

Your numbers stay with you

Your numbers are saved only in your browser. Tagzinho has no accounts and never sends what you type anywhere. Marketplace fees change often, so Tagzinho doesn’t fill them in for you: you type the fees of wherever you sell, from its fee page or your seller account.
