How to calculate the calories in a recipe
The math behind every nutrition label — done for you in one click.
To find the calories in a recipe, each ingredient is converted to grams, multiplied by its calories per 100 grams, and summed. Divide the total by the number of servings to get calories per serving. The same scaling gives you protein, carbohydrates, fat, fiber, and sodium. This calculator runs that process across a 100+ ingredient USDA database the instant you type.
Step by step
1. List your ingredients. Type each one and choose the matching USDA item from the suggestions.
2. Enter the amount and unit. Grams, cups, tablespoons, teaspoons, ounces, pounds, millilitres, and kilograms are all supported and converted automatically.
3. Set the servings. This turns whole-recipe totals into a clean per-serving number.
4. Read your results. Calories per serving is shown large; macros and sodium sit right below, with the full-recipe totals underneath.
What this recipe calculator measures
Calories — the energy in one serving, the number most people search for when they want to know how many calories are in their recipe.
Macros (protein, carbs, fat) — the three macronutrients used for macro tracking, keto, bulking, or cutting. Use it as a recipe macro calculator for any homemade meal.
Fiber — counted separately from carbohydrates so you can see net-carb impact at a glance.
Sodium — shown in milligrams per serving. The FDA daily limit is 2,300 mg, so if a serving reads 600 mg it is about a quarter of a full day. Salty staples like soy sauce, bacon, and cheese move this number fast.
How accurate is it, and where does the data come from?
Every value is drawn from USDA FoodData Central, standardized to nutrition per 100 grams. Because it uses the same reference data professional tools rely on, results are dependable for meal planning, macro tracking, and label-style estimates. Exact figures still depend on your specific brand, cut, and cooking method, so treat the output as a close, honest estimate rather than a lab measurement. Nothing you enter is uploaded — the entire calculation happens locally in your browser.
Frequently asked questions
How do I calculate the calories in a recipe?
List every ingredient with its amount, convert each to grams, and multiply by its calories per 100 g. Add them up and divide by servings. This tool does all of it automatically from USDA data the moment you enter your ingredients.
Is this recipe nutrition calculator free?
Yes — completely free, no signup, no account, no limits. Everything runs in your browser, so your recipes are never uploaded or stored.
Can it calculate macros like protein, carbs, and fat?
Yes. Alongside calories it shows protein, carbohydrates, fat, fiber, and sodium — both for the whole recipe and per serving — so it doubles as a recipe macro calculator.
Where does the nutrition data come from?
From USDA FoodData Central, expressed per 100 g for 100+ common cooking ingredients. Results are estimates and can vary with brand, cut, and preparation.
How is sodium per serving calculated?
Each ingredient's sodium per 100 g is scaled by your amount, summed, then divided by servings. The FDA limit is 2,300 mg/day, so a serving above ~575 mg is roughly a quarter of a day.
How accurate is the recipe calorie calculator?
Accurate enough for planning and label-style estimates because it uses standardized USDA values. Exact numbers depend on your products and cooking method, so treat it as a close estimate.
