Four calculators, one ingredient set. Each opens in place, nothing to install, nothing to log in to.
Recipe ingredient scaler
Paste your ingredient list, set original and desired servings, and scale instantly.
For people who sell
what they bake
or cook
Every calculator on this page is free and stays free. IngredientCalculator Pro is for the cottage baker, the market stall, the caterer and the meal-prep seller who need the numbers to hold: what a batch costs, what to charge for it, and how much to buy for an order of fifty.
Recipe costing and pricing
Price every ingredient from the pack you buy it in. Read the cost per batch and per serving, set a target food-cost percentage, and get the selling price and margin. Prices are remembered in your browser, and the result exports to CSV.
Recipe library and batch scaling
Save recipes in the browser, import and export them as JSON, and scale up to 50 saved recipes in one pass.
Merged shopping list and print cards
One CSV shopping list across every recipe, with like ingredients merged on the density table, and clean recipe cards for the printer.
The Kitchen Pack offline
Nine files that run with the connection off: a ten page printable PDF reference, five single file HTML tools, and the ingredient data as CSV and JSON.
The arithmetic
no recipe
ever shows you.
Doubling a family recipe, halving a sheet of cookies, or turning a European bake into something your imperial measuring cups can handle. The math is fiddly. We do it so you don't have to.
Up, down, sideways
Parses fractions, decimals, and unicode glyphs. Returns readable fractions back.
Cups ⇄ grams ⇄ °C
Volume, weight, and temperature, with a quick-reference for the things you forget at 7 am.
For when you're out
17 staple ingredients, several swaps each, with ratios and editor notes on which is which.
Quick macro math
USDA per-100g averages for 25+ ingredients. A sanity-check, not a meal plan.
A cup is
not a cup.
Volume measurements lie. The same cup holds anywhere from 90 grams of rolled oats to 340 grams of honey, almost four times the weight. It's why your grandmother's recipe never tastes the same twice, and why bakeries weigh.
