Whether you’re meal prepping, following a macro-based diet, or simply curious about the fat content of your homemade blends, the Mix Fat Calculator helps you determine the total fat, fat per serving, and fat percentage of any mixture. Simply enter the weight and fat content of each ingredient, and the tool does the rest.
This calculator is ideal for anyone tracking macronutrients — from fitness enthusiasts and dietitians to home cooks managing conditions like high cholesterol or pancreatitis. It supports up to five ingredients, handles both grams and ounces, and provides a clear breakdown of your mix’s fat profile. No more manual math or guesswork.

How to Use This Tool
Using the Mix Fat Calculator is straightforward. Start by selecting the number of ingredients in your mixture (2 to 5). For each ingredient, enter its weight and the fat content per 100 grams (you can find this on nutrition labels or in our ingredient database). Choose the unit — grams or ounces — and the calculator automatically converts everything to grams for consistent results. Click "Calculate" to see the total weight, total fat, fat percentage, and fat per 100g of the final mix. Use the "Reset" button to clear all fields and start a new calculation.
💡 Pro Tip: For the most accurate results, use the exact fat values from the nutrition facts panel of each ingredient. If an ingredient has 0g fat, simply enter 0.
Formula Explained
The calculator uses a simple weighted average approach. For each ingredient, the fat contribution is calculated as: (fat per 100g / 100) × weight in grams. The total fat is the sum of all individual fat contributions. The fat percentage of the final mix is: (total fat / total weight) × 100. This is the same method used by dietitians and food manufacturers to determine the macronutrient profile of blended foods.
Worked Examples
Example 1: Simple Two-Ingredient Mix
You mix 200g of Greek yogurt (fat: 5g/100g) with 50g of honey (fat: 0g/100g).
Yogurt fat: (5/100) × 200 = 10g. Honey fat: 0g. Total fat: 10g. Total weight: 250g. Fat percentage: (10/250) × 100 = 4.00%. Fat per 100g: 4.00g.
Example 2: Three-Ingredient Salad Dressing
You combine 30g olive oil (fat: 100g/100g), 20g balsamic vinegar (fat: 0g/100g), and 10g Dijon mustard (fat: 10g/100g).
Olive oil fat: (100/100) × 30 = 30g. Vinegar fat: 0g. Mustard fat: (10/100) × 10 = 1g. Total fat: 31g. Total weight: 60g. Fat percentage: (31/60) × 100 = 51.67%. Fat per 100g: 51.67g.
Common Mistakes to Avoid
- Mixing units without conversion: Always ensure you use the same unit for all ingredients, or let the calculator handle conversion by selecting the correct unit per ingredient.
- Entering fat as a percentage instead of grams per 100g: The fat field expects the number of grams of fat in 100g of the ingredient (e.g., 20 for 20% fat), not the percentage symbol.
- Forgetting to include all ingredients: If you have more than 5 ingredients, calculate in batches or combine similar items first.
Real-World Applications
This calculator is useful for anyone managing their dietary fat intake. Fitness enthusiasts use it to balance macros in homemade protein bars or meal prep. Individuals on low-fat diets (e.g., for pancreatitis or gallbladder issues) can precisely control fat content. Chefs and food bloggers use it to standardize recipes. It's also handy for parents preparing homemade baby food who want to monitor fat levels for healthy development.
Frequently Asked Questions
Q: Can I use this for liquids and solids together?
A: Yes, as long as you have the fat content per 100g for each ingredient, the calculator works for any consistency.
Q: What if my ingredient's fat content is listed per serving, not per 100g?
A: Convert it first. For example, if a 30g serving has 5g fat, then fat per 100g = (5/30) × 100 = 16.67g. Enter 16.67 in the fat field.
Q: How accurate is the result?
A: Accuracy depends on the precision of your inputs. The calculator itself is mathematically exact. For best results, use a kitchen scale and read nutrition labels carefully.
