Recipe Nutrition Calculator
Most recipe sites guess their nutrition numbers. This is the same ingredient-density-based calculator we use to verify every recipe on Zest & Squeeze: enter real ingredient amounts and it computes calories, fat, carbs, and more from actual per-ingredient data, not a rough estimate.
Paste a whole ingredient list and it fills in the rows for you. Try it on your family's recipes, or on one from another site or a cookbook to get a second opinion on its numbers.
Copy the ingredients from any recipe, then click the button. Each line is read for its amount, unit and ingredient, matched to the database, and anything that needs you is flagged below.
Or type or edit the recipe as text
Or add ingredients one at a time. Amounts accept whole numbers (2), decimals (0.5), fractions (1/3), mixed numbers (1 1/2), or ranges (2-3, averaged).
How many servings does this recipe make? Results below are calculated per serving, not per 100g.

Common questions
It computes real numbers from a per-100g nutrition database and each ingredient's actual real-world density, the same calculator used to verify every recipe on this site, not a rough guess. It's accurate enough to catch a recipe that's wildly wrong, but for medical or strict dietary tracking, always double check against a labeled product or a registered dietitian.
The database covers over 700 ingredients and ingredient names, from everyday staples to spices, sauces, and drinks, but it can't cover every brand name or unusual phrasing. If an ingredient isn't recognized, it's excluded from the total and flagged clearly, with a "did you mean" suggestion when something close exists, rather than silently counted as zero calories.
It treats ingredients as raw or uncooked by default, the way recipes are normally written. "1 cup rice", "8 oz pasta", and "1 cup quinoa" are counted as dry amounts, which is roughly three times the calories of the same volume once cooked. If your recipe lists a cooked amount, write the word "cooked" in the ingredient name (for example "cooked rice") and it will use cooked values instead.
Yes. The unit dropdown includes grams, kilograms, milliliters, and ounces/pounds alongside cups, tablespoons, and teaspoons, so you can enter a recipe exactly as it's written in either system.
It means the total nutrition of everything you entered, divided by the number you put in the Servings field. It has nothing to do with a 100g serving size, it's based on however many servings your specific recipe makes.
Yes. Copy the ingredient list from any recipe (a family recipe, a cookbook, or a website), paste it into the box at the top, and the calculator works out the nutrition from the amounts. It is a handy second opinion: many recipes online publish rough or unverified numbers, and comparing them with a calculation from the actual ingredients shows where they differ. Treat it as an estimate, since brands and how you measure will move the numbers a little.
Yes, completely free, no account or sign-up required. It's the same tool we built to keep our own recipes honest, made public because most recipe sites guess their nutrition numbers instead of computing them.
Add this calculator to your website
Copy the code below and paste it into any page or blog post that accepts HTML. It is free, needs no sign-up, and updates automatically when we review the underlying research.
Why add it to your site
- It computes nutrition from real ingredient weights and densities using per-100g reference data, instead of guessing from a similar recipe.
- Ingredients it cannot recognise are flagged, never silently counted as zero, so results stay honest.
- It is the same engine we use to verify every recipe on Zest & Squeeze.
- No sign-up, no email gate, and results are labelled as estimates, not lab-tested data.
