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

  1. Enter your total daily calorie target.
  2. Choose what percentage of calories should come from fat.
  3. 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.
