Soap Making: see your true cost

This is the actual Anvil HUD pricing engine running on researched preset numbers, set up as a cold-process loaf cut into bars. Move a number and watch the price move. No account, nothing stored.

A 1,000 g oil recipe (olive, coconut, shea) with the lye derived from real saponification values. The price is per bar.

Every other number (machine, rates, fees) rides on the same presets a new workbench starts with. Sign in to use yours.

What you are looking at

  • The same formula the app runs: raw cost, times failure buffer and overhead, solved so the marketplace cut cannot eat your margin. Every line is published at /the-math.
  • The presets are researched 2026 US figures, cited at /sources. A new workbench starts with exactly these and you tune everything to your shop.
  • Signing in swaps the presets for your real machines, materials, rates, and fee profiles, and lets you save products, log jobs, and learn your true failure rate.

Make it your number
