Recipe Nutrition Calculator
Search 2+ million foods and calculate recipe nutrition
How Is Recipe Nutrition Calculated?
Per-ingredient sum / servings — Each ingredient's calories and macros are looked up from the OpenFoodFacts database, multiplied by the specified amount, then totaled and divided by the number of servings.
Result: Per-serving calories, protein, carbohydrates, and fat for your custom recipe.
- Key variables: ingredients (type and quantity), number of servings
- Limitation: Accuracy depends on ingredient selection — cooking methods can alter caloric density by 5-15%

What Is a Recipe Nutrition Calculator?
Easily see the calories, protein, carbs & fat for any recipe by analyzing ingredient data from OpenFoodFacts. Instead of guessing, you get estimated per-serving values based on real food data.
This calculator searches the OpenFoodFacts database — an open-source, community-verified collection of over 2 million food products from around the world. Every entry includes standardized nutrition facts per 100g, which we scale to your portion size.
Why OpenFoodFacts?
Unlike proprietary databases that lock data behind paywalls, OpenFoodFacts is open, transparent, and community-contributed. Products are scanned from real packaging by contributors worldwide and available for anyone to inspect. Accuracy varies by entry — always verify critical values against product labels.
How to Use
- Search for any food using the search bar above
- Click on a food to select it
- Enter the amount in grams for your recipe
- Add multiple ingredients to build your complete recipe
- Adjust servings to see per-serving nutrition
Accurate Recipes Need Accurate Measurements A food scale eliminates guesswork—know exactly how many grams you're adding. Essential for consistent nutrition tracking and meal prep.

How Are Nutrition Values Calculated?
Nutrition values come from standardized 100g data in OpenFoodFacts, scaled to your ingredient amounts using a simple formula.
Nutrient = (amount in grams / 100) x nutrient per 100g
Per-Serving Nutrition:
Nutrient per serving = Total recipe nutrient / number of servings
What Nutrients Are Tracked?
For each recipe, you get four key macronutrients:
| Nutrient | Calories per Gram | Why It Matters |
|---|---|---|
| Calories (kcal) | — | Total energy from all macros combined |
| Protein | 4 kcal/g | Muscle repair, satiety, essential for recovery |
| Carbohydrates | 4 kcal/g | Primary energy source for training and daily activity |
| Fat | 9 kcal/g | Hormone production, vitamin absorption, energy reserve |
Use these per-serving values alongside your daily targets from the Macro Calculator to hit your protein, carb, and fat goals consistently.
How Accurate Is This Calculator?
Accuracy depends on verified OpenFoodFacts data and precise measurements — get reliable results for every recipe. For best results:
- Use a kitchen scale for gram-based measurements (+/- 2% accuracy)
- Search for specific brands when possible (e.g., "Barilla penne" instead of "pasta")
- For raw ingredients (chicken, rice, vegetables), search the generic entry
- Remember that cooking methods (frying vs. boiling) can change calorie density
Frequently Asked Questions
Where does the nutrition data come from?
We use OpenFoodFacts, the world's largest open food database with over 2 million products. Data is crowd-sourced and verified by the community.
How accurate is the nutrition information?
Accuracy varies by entry. Branded products usually have reliable data from packaging. Generic entries are estimates. Look for the "More complete" badge and verify critical items with official sources when possible.
Can I save my recipes?
Yes! Click "Save Recipe" to store it in your browser. Your recipes will be available next time you visit. You can also copy the nutrition info to share.
How do I calculate calories in a homemade recipe?
Search for each ingredient, enter the amount in grams, and the calculator totals all nutrition automatically. Divide by servings to get per-portion values. For best accuracy, weigh ingredients with a kitchen scale instead of using volume measurements (cups, tablespoons).
What is the difference between raw and cooked nutrition values?
Raw and cooked weights differ because food loses water during cooking. 100g of raw chicken breast becomes roughly 75g cooked, but the calories stay the same. Always enter the weight that matches the database entry you selected — if you pick "raw chicken breast," weigh it raw before cooking.
How do I track macros for meal prep?
Build your full recipe, set the number of servings to match your meal prep containers, and the calculator gives you estimated per-container macros. Save the recipe so you can reference it throughout the week without recalculating.
Why do nutrition labels differ from calculated values?
Nutrition labels are allowed a margin of error (up to 20% in the US). Additionally, brands may round values, and generic database entries are averages across multiple products. Small differences of 5-10% between label and calculated values are normal and expected.
Can I use this calculator for weight loss meal planning?
Yes. Calculate your daily calorie target using a TDEE calculator, then build recipes that fit your budget. Knowing estimated per-serving calories reduces guesswork and makes it easier to maintain a consistent calorie deficit.
How many servings should I set for my recipe?
Set servings to match how many portions you actually eat. If you make a pot of chili and eat it over 4 meals, set servings to 4. For a single meal, set it to 1. The calculator divides total nutrition by your serving count to give per-portion values.
Does cooking change the calorie content of food?
Cooking changes the weight of food (water evaporates), not the total calories. However, adding oil, butter, or sauces during cooking adds calories that were not in the raw ingredients. Always account for cooking fats as separate ingredients for better tracking.
Choosing Better Ingredient Matches
The quality of your recipe estimate depends heavily on which search results you select. Here's how to pick the best match:
- Prefer generic raw ingredients for cooking basics — search "chicken breast raw" rather than a specific branded package
- Use branded items only when you're using that exact packaged product (e.g., a specific yogurt brand)
- Look for the green "More complete" badge — entries with fuller nutrition data give more reliable results
- Check per-100g values before adding — if protein, carbs, or fat seem unusually high or low, try a different entry
- Stay consistent with raw vs cooked — don't mix raw chicken with cooked rice in the same recipe; pick one basis and stick with it
- When in doubt, choose the simpler entry — "Rice, white, cooked" is usually more reliable than a branded ready-meal that happens to contain rice
Common Recipe Tracking Mistakes
- Using volume instead of weight: "1 cup of rice" varies significantly. Weigh ingredients in grams for consistent results.
- Mixing raw and cooked entries: 100g raw chicken ≠ 100g cooked chicken. Be consistent — pick one and stick with it.
- Forgetting oils and sauces: A tablespoon of olive oil adds 120 calories. Small additions add up fast.
- Not dividing by actual servings: Per-serving macros are only reliable if you divide the total recipe by the number of servings you actually eat.
