About the Fat Intake Calculator
Dietary fat is essential for hormone production, nutrient absorption, and long-lasting energy, and your ideal intake is best set as a percentage of total calories.
Formula Used
Fat (g) = (Daily Calories × Fat%) / 9
How It Works
This calculator converts your chosen percentage of daily calories from fat into grams, using the standard 9 calories per gram of dietary fat.
Step by Step
- Enter your total daily calorie target.
- Choose what percentage of calories should come from fat.
- Divide the resulting calories by 9 (calories per gram of fat).
Worked Example
Example: 2200 kcal/day at 30% fat:
Fat = (2200×0.30)/9 = 73 g/day
Frequently Asked Questions
How much fat should I eat daily?
General guidelines suggest 20-35% of total daily calories from fat for most healthy adults.
Are all fats treated the same?
No, this calculator estimates total fat grams only; it's still important to favour unsaturated fats over trans and excess saturated fats.
Why does fat have more calories per gram?
Fat provides 9 calories per gram compared to 4 calories per gram for protein and carbohydrates, making it the most calorie-dense macronutrient.
