What is Recipe Calculator?
A web tool that turns any recipe into accurate per-serving nutrition — carbs, protein, fat, fiber, and calories — in seconds.
In one sentence
Add ingredients with their per-gram nutrition, set your batch and serving sizes, and Recipe Calculator shows exactly what's in each serving.
The problem it solves
Anyone who cooks in quantity faces the same headaches:
- Manual calculation is slow. A 12-ingredient recipe takes 20–40 minutes in a spreadsheet — and mistakes creep in.
- Unit conversion is a nightmare. 1 cup of water = 240 g, but 1 cup of rice = 158 g and 1 cup of honey = 340 g. Most apps use one fixed number and get it wrong.
- Nutrition databases disagree. The same "chicken breast" has different macros depending on the source.
- Menu labeling is often required by law. Restaurants and packaged-food producers need accurate nutrition panels.
- Diet-focused customers ask: "what are the macros?" Businesses that answer fast win customers.
How Recipe Calculator solves it
- 60-second calculation — add ingredients, set batch/serving size, done.
- Per-ingredient unit conversion — you tell it that 1 cup of rice weighs 158 g, and it remembers.
- Your data, your control — you enter the macros from your supplier's label or a trusted database. Numbers are consistent.
- Compliance-ready output — export a PDF with per-serving and whole-recipe nutrition.
- Live updates — change one ingredient, and every number recalculates instantly.
The math (it's simple)
