What This Calculator Does
The Daily Fat Intake Calculator estimates how much dietary fat you need based on your total calories and the percentage of fat in your diet. Fat is essential for hormone production, vitamin absorption, and brain function.
How It Works
Multiply daily calories by the fat percentage, then divide by 9 (calories per gram of fat).
Example
On a 2,000 kcal diet at 30% fat: 2,000 x 0.30 / 9 = 67 grams of fat per day.
Formula
Fat (g) = Calories x Fat% / 9Reading the Results
Daily Fat Target
Grams of dietary fat to consume daily.
Fat Calories
How many daily calories come from fat.
Frequently Asked Questions
How much fat should I eat per day?
Most guidelines recommend 20-35% of total calories from fat. For 2,000 kcal, that is 44-78 grams per day.
Is dietary fat bad for you?
No. Healthy fats from olive oil, nuts, avocados, and fish are essential. The concern is excessive saturated and trans fats.
What happens if I eat too little fat?
Very low fat intakes can impair hormone production and reduce absorption of fat-soluble vitamins (A, D, E, K).
