Soap Pricing Calculator: the true cost of your handmade soap
Price a bar of cold process soap on what your batch actually costs: the oils, the lye they need, fragrance, and your time, split across the bars a batch makes.
Soap pricing trips people up because it's made in batches: a loaf costs you oils, lye, fragrance, and an hour of work, then becomes ten or more bars, and the per-bar cost is easy to undercount. Anvil HUD prices a bar the honest way: your recipe's oils, the lye they saponify into, fragrance at your load percent, colorant and packaging, and your hands-on minutes, all divided by the bars your mold yields. Curing is passive and the mold is reusable, so there's no machine time to bill. Not sure on your lye or water? The built-in lye + batch calculator runs the saponification math from your oils and superfat.
How we price soap making
- Your recipe (the oils, by the gram) sets the oil cost and the lye it needs; add fragrance at your load percent, colorant, and packaging.
- The mold sets how many bars a batch yields, so the batch cost divides into a per-bar cost; a failure buffer and overhead load it; your fees and margin set the price.
- No file to drop: build your recipe, pick a mold, set the superfat and fragrance load. The lye calculator works out the lye, water, and fragrance for you.

Questions
How do I price handmade soap?▾
Add up your batch's oils, the lye they need, fragrance at your load percent, colorant, packaging, and your hands-on time, divide by the bars the mold yields, then load a failure buffer and overhead and divide by one minus your fees and target margin. The mold is reusable, so it's overhead, not a per-bar cost. Anvil HUD does the math and publishes the formula at /the-math.
How much lye does my recipe need?▾
Use the built-in lye + batch calculator: enter your oils (each with its SAP value) and a superfat percent and it works out the NaOH, water, fragrance, batch weight, and cost, then sends the recipe into the estimate. It runs in your browser and it's free. Always confirm your lye amount before mixing.
Is the calculator free?▾
