Fat Intake Calculator
Estimates daily dietary fat needs from your estimated calorie requirements: a recommended intake at 25–30% of calories, the full 20–35% healthy range in grams, and the 10% saturated-fat ceiling for heart health.

Fat grams across the healthy calorie range
9 kcal per gram of fat. The saturated-fat ceiling is 10% of total calories at every fat share.
Favor unsaturated fats (olive oil, nuts, fatty fish, avocado); strictly avoid artificial trans fat. Very-low-fat diets (<20%) can impair hormone production. Estimates for informational purposes only — not medical advice.

Formula
Fat (g/day) = (TDEE × fat %) ÷ 9 kcal per gram
- • Estimate daily calories: BMR (Mifflin-St Jeor) × activity factor.
- • Pick a fat share — 20–35% of calories is the accepted healthy band (25% shown as the default).
- • Divide fat calories by 9 for grams; cap saturated fat at 10% of total calories.
Pro tips
- • Fat is calorie-dense (9 kcal/g) — measuring oils and nut butters is the easiest win for a calorie deficit.
- • Aim for most fat unsaturated: fish, olive oil, nuts and seeds support cholesterol profiles.
- • Do not drop below ~0.5 g/kg — essential fatty acids are needed for hormone and brain health.
