A handmade product can appear profitable while quietly leaving the maker unpaid. To avoid that, separate three decisions: what the batch costs, how many sellable units it produces, and what percentage of the selling price should remain after the entered costs and fees.
1. Start with the batch, not the price tag
Imagine a batch of ten cotton pouches. Materials cost 30 in your currency. You add a 10% material allowance, bringing the material estimate to 33. Two hours at 12 per hour adds 24. Allocate 6 of batch overhead and 1 of packaging per pouch. Total batch cost is 33 + 24 + 6 + 10 = 73. Cost per sellable pouch is 7.30.
Labor here is a cost allocation for your time. Profit is what remains after that allocation and other entered costs; it is not the same as money available before paying yourself.
2. Margin and markup use different denominators
A 30% markup on 7.30 gives 9.49. Before selling fees, that leaves 2.19, which is only about 23.1% of the selling price. A 30% margin requires 7.30 ÷ 0.70, or about 10.43 before fees. Neither percentage is inherently correct for your business; the important thing is to name it accurately.
3. Include fees in the right place
If a selling channel charges 5% of the selling price plus 0.30 per sale, a target 30% margin gives: price = (7.30 + 0.30) ÷ (1 − 0.30 − 0.05) = 11.6923. At the displayed 11.69 price, actual margin differs slightly because of rounding. If an order contains several items, allocate the fixed order fee rather than charging it to every unit twice.
4. Use sellable output
If the same batch produces only eight saleable pouches, divide the batch costs across eight. The material allowance is a percentage added to material cost, not an automatic reject-rate model. Avoid counting the same loss both as extra material and reduced output without checking what each number represents.
5. Check the real sale
The calculator does not discover your marketplace’s rules, collect sales tax, estimate shipping, or decide what customers will pay. Enter your own fees and overhead, compare prices with your market, and revisit costs when materials change. Treat the output as a planning estimate.
