Calculate total recipe calories by adding ingredients and their weights. Built-in food database with 50+ common ingredients for quick lookup.
Knowing the calorie content of a full recipe starts with knowing the calorie content of each individual ingredient. Whether you're meal prepping, developing recipes, or tracking nutrition, calculating per-ingredient calories and summing them gives you the most accurate total.
This calculator includes a built-in database of 50+ common cooking ingredients with their calorie and macro values per 100 grams. Simply select an ingredient, enter the weight you're using, and the calculator computes the calories and macros contributed by that ingredient. Add multiple ingredients to build your full recipe.
The per-ingredient approach is more accurate than estimating a finished dish because cooking methods, portion sizes, and ingredient quantities vary widely between recipes. By summing from ingredients, you account for your exact portions. Whether you are a beginner or experienced professional, this free online tool provides instant, reliable results without manual computation. By automating the calculation, you save time and reduce the risk of costly errors in your planning and decision-making process.
Restaurant and packaged calorie counts are estimates. When you calculate from raw ingredients, you get precise nutrition data for your actual recipe. This is essential for anyone tracking macros, meal prepping, or managing a medical diet where accuracy matters. Having a precise figure at your fingertips empowers better planning and more confident decisions.
Ingredient Calories = (weight in grams / 100) × calories per 100g Same for macros: Protein (g) = (weight / 100) × protein per 100g Carbs (g) = (weight / 100) × carbs per 100g Fat (g) = (weight / 100) × fat per 100g Total Recipe = ∑ all ingredient values Per Serving = Total Recipe / number of servings
Result: Total: 638 kcal (319 kcal/serving)
Chicken breast: 200g × 1.65 kcal/g = 330 kcal. Brown rice (cooked): 150g × 1.12 kcal/g = 168 kcal. Broccoli: 100g × 0.34 kcal/g = 34 kcal. Olive oil: 15g × 8.84 kcal/g = 133 kcal. Total = 665 kcal. Divided by 2 servings = 333 kcal/serving with 42g protein, 28g carbs, 17g fat per serving.
Estimating calories from a finished dish (e.g., “one plate of stir-fry”) can be off by 30–50%. The same dish varies enormously depending on how much oil was used, the ratio of meat to vegetables, and the portion size. Breaking a recipe into individual ingredients eliminates this guesswork and gives you reproducible, accurate nutrition data.
Once you calculate a recipe, note the total calories and servings. Over time, you build a personal recipe database where you know the exact nutrition of your most-cooked meals without re-calculating. This is the approach used by competitive athletes, bodybuilders, and registered dietitians for precise nutrition management.
Some ingredients contribute far more calories than expected: cooking oils (884 kcal/100g), nuts (550–650 kcal/100g), dried fruits (300–350 kcal/100g), and cheese (350–450 kcal/100g). Conversely, most vegetables (15–45 kcal/100g) and lean proteins (100–165 kcal/100g) are surprisingly low-calorie, making them the best “volume foods” for satiety.
The built-in database uses values from the USDA FoodData Central database, the most comprehensive and authoritative food composition database in the world. Values are per 100 grams of edible portion. For packaged ingredients, nutrition label values may differ slightly due to rounding rules.
Weigh raw/dry ingredients whenever possible, as the database values correspond to raw products. Cooking changes the water content (and therefore weight per calorie) but doesn't change the total calories. For example, 100g raw rice becomes ~250g cooked, but the calorie count stays the same.
Ingredient-based counting is the most accurate practical method, typically within 5–10% of actual calorie content. The main sources of error are: incomplete absorption of nutrients, thermic effect of cooking, and natural variation in food composition. For most purposes, this level of accuracy is more than sufficient.
Yes, always. Oil is extremely calorie-dense (about 120 calories per tablespoon/15ml). Even a tablespoon of oil used for sautéing adds significant calories. If oil is discarded after cooking (like deep-fry oil), estimate the absorbed amount instead.
Use the custom ingredient option to enter calories and macros per 100g manually. You can find this information on the product nutrition label, the USDA FoodData Central website (fdc.nal.usda.gov), or apps like MyFitnessPal. Enter values per 100g for consistency.
Cooking doesn't significantly change the calorie content of the food itself, but added fats (oil, butter) and coatings (batter, breading) add calories. The main exception is that some cooking methods (like pressure cooking legumes) may slightly improve nutrient absorption, but the effect on calories is negligible.
