SoapCalc is the cheapest paid soap software in 2026 — Starter is $9.90/year — and its free plan is the only one that gives you the full calculator andsaved recipes. Here's how the main tools actually compare on price.
| Tool | Free plan | Paid price | Saves recipes | Inventory / batches |
|---|---|---|---|---|
| SoapCalc | Full calc + 10 saved recipes, no ads | Starter $9.90/yr · Maker $3.99/mo · Studio $7.99/mo | ✅ (free) | ✅ (Maker+) |
| soapcalc.net | Full calc, ad-supported | — | ❌ no account | ❌ |
| SoapmakingFriend | 2 recipes, 1 batch, ads | $5.99/mo · $39.99/yr | ⚠️ paid | ✅ (mature mobile app) |
| The Cosmetics Lab | 20 recipe limit | — | ⚠️ limited | ❌ |
| Craftybase | — | from $49/mo | ❌ no calculator | ✅ (full manufacturing) |
Prices verified 2026-07-08 from each tool's own pricing page. We keep this honest: SoapmakingFriend has a mature native mobile app that SoapCalc doesn't — if a phone app is your priority, try it. SoapCalc wins on price, on full inventory + costing, and on being the free calculator that remembers your work.
The cheapest way to save your soap recipes
Most "free" soap calculators forget everything the moment you close the tab. SoapCalc's free plan saves up to 10 recipes (imports don't count), keeps your ingredient library, and never shows ads. When you outgrow it, Starter is $9.90/year — the cheapest paid door in the category.
When cheaper isn't the point
If you sell soap, the math changes: inventory, batch costs, COGS margins, labels, and compliance save real money and time. SoapCalc Studio bundles all of it for $7.99/month — where Craftybase charges $49/month and still has no soap calculator.
