Fat Intake Calculator
Free fat intake calculator: convert daily calories and a fat percentage into grams of fat per day, with the 20-35% guideline table and saturated-fat cap.
About the Fat Intake Calculator
Fat is the most calorie-dense macronutrient at 9 kcal per gram, so daily fat grams = (calories × fat share %) ÷ 100 ÷ 9. This free fat intake calculator converts your daily calories and preferred fat percentage into a grams-per-day target, shows a comparison table across the guideline range of 20-35% of calories, and adds the commonly advised saturated-fat cap of about 10% of calories.
On a 2,200 kcal diet, a 30% fat share means about 73 g of fat per day, of which no more than roughly 24 g should be saturated. Dieters balancing macros, people managing cholesterol with their doctor, and anyone planning meals around ghee, cooking oil and nuts — significant fat sources in Pakistani and Indian kitchens — can use the table to pick a sensible level. Needs vary by individual.

Frequently Asked Questions
How many grams of fat should I eat on 2,000 calories?
At 30% of calories: 2,000 × 0.30 = 600 kcal from fat, ÷ 9 = 67 g per day. The 20-35% guideline range corresponds to 44-78 g on the same calories — the calculator's table shows each step.
Why does fat have 9 calories per gram?
That is the Atwater factor for fat — more than double the 4 kcal/g of protein and carbohydrate, because fat molecules store more chemical energy. It is why small amounts of oil add up fast: one tablespoon (~14 g) is about 126 kcal.
How much saturated fat is too much?
Common guidelines suggest keeping saturated fat under about 10% of calories — on 2,200 kcal that is 220 kcal ÷ 9 ≈ 24 g per day. Butter, ghee, fatty meat and coconut oil are the main sources to count. People with heart conditions may be advised lower; ask your doctor.
Is a very low-fat diet a good idea?
Going below about 20% of calories long-term can shortchange essential fatty acids and the absorption of vitamins A, D, E and K. Unless medically directed, staying within the 20-35% range while favouring unsaturated sources (nuts, fish, olive and canola oil) is the mainstream recommendation.
