Free tier: you know your lye is right.

Paid tier: you know your lye is right, your castor oil is low, batch 7 cures Friday, you sold 14 bars last week, and your margin is 34%.

Same soap. Completely different business.

Lather Logic Lab started as a formulation calculator. The paid plan is the operations layer that serious makers actually need.

Inventory. Curing. Sales. Expenses. Seasonal collections. One place.

Send this to the maker in your life still running everything on a spreadsheet.

A lye calculator doesn't run a soap business.

It doesn't track what's going low in your inventory.

It doesn't tell you which batch finishes curing on Friday.

It doesn't log what you sold at the market last weekend.

It doesn't show you if you're actually profitable.

You're calculating correctly and still flying blind.

Lather Logic Lab has the full layer - inventory, curing dashboard, sales, expenses, seasonal collections - all in one place.

Free gets you started. Paid runs the business.

Most soap calculators give you the same generic SAP values everyone else uses.

Lather Logic Lab uses mine.

Values I've tested, cross-referenced, and refined across real batches - not pulled from a shared industry table that hasn't been updated in years.

Here's what you can actually do with it:

→ Input any custom oil blend
→ Choose your soap type: cold process, hot process, liquid KOH, or melt & pour
→ Set your superfat and water discount exactly
→ Get precise lye amounts - NaOH, KOH, or dual lye

No spreadsheet. No guessing. No recalculating because you changed one oil.

Free tier gets you full access to the calculator from day one.

Save this for your next batch.
