Free calculators for bakers, built like a reference tool — not a subscription app
Baker's percentage, recipe costing, batch scaling, menu pricing, bake loss and dough temperature — no account, no recipe limits, no paywall. Every formula is cited, with worked examples and guides that explain the method behind each number.
Baker's Percentage Calculator
Turn a dough formula into baker's percentages (flour = 100%), or go the other way: percentages + target flour weight → exact ingredient weights.
Open →Recipe Cost Calculator
Cost out any recipe from what you actually paid for ingredients, down to cost-per-portion — bread, cakes, pastries, anything.
Open →Batch Scaling Calculator
Scale a recipe to any multiplier or target yield — with an optional large-batch adjustment for yeast and salt, not just straight multiplication.
Open →Menu & Product Pricing Calculator
Turn a cost-per-unit into a menu or product price using the standard food-cost-percentage method, with cited industry benchmark ranges.
Open →Bake Loss Calculator
How much dough to scale for a loaf of a given baked weight, or measure the weight your bread actually lost in the oven and while cooling.
Open →Dough Temperature (Water Temp) Calculator
The water temperature that lands your dough at its target temperature, using the desired-dough-temperature formula, with or without a preferment.

Why this exists
Most free baking calculators online only do simple percentage math, and most recipe-costing tools cap you at a handful of saved recipes unless you pay a monthly fee for what is otherwise a full kitchen-management app you may not need. BakeryMath is just the math layer — free, no account, no caps — with the formula, a worked example and the sources written out under every calculator, so you can check the numbers yourself.
