Our free Fat Intake Calculator estimates your daily fat allowance — including total fat, saturated fat, and heart-healthy saturated fat limits — across five different weight goals. Enter your age, gender, height, weight, and activity level to see your personalized fat targets based on your actual calorie needs, not a generic 2,000-calorie average.
How to Use This Calculator
1
Enter your age, then select your gender — both are used in the BMR calculation.
2
Enter your height in cm and weight in kg for an accurate metabolic rate estimate.
3
Select your activity level — this multiplies your BMR to give your total daily calorie needs.
4
Click Calculate to see your fat allowance across five goals: maintenance, two weight loss, and two weight gain targets.
5
Use your saturated fat limit (10%) and heart-healthy limit (7%) to guide your food choices within your total fat range.

Frequently Asked Questions
Fat intake during weight loss scales with your reduced calorie target. The 20-35% range still applies — what changes is the total calorie number it's calculated from. Use the calculator above with your weight loss goal selected to see your specific fat target.
The 10% limit is the general population guideline. The 7% limit is recommended for people specifically trying to reduce cardiovascular disease risk, as studies suggest the tighter ceiling has a more meaningful effect on LDL cholesterol levels.
No. Dietary fat is not the direct cause of fat gain — excess calories are. Fat is calorie-dense at 9 calories per gram, so it's easy to overeat, but staying within your fat allowance while in a calorie deficit will support weight loss regardless of your fat percentage.
Yes. The calculator multiplies your BMR by an activity factor to estimate your total daily energy expenditure (TDEE), then applies the fat percentage ranges to that personalized calorie total — not a generic 2,000-calorie figure.
