Daily Fat Intake Calculator

Find your daily fat target.

How it is calculated

The tool turns a calorie target and a fat share into grams: grams of fat = calories × (percent ÷ 100) ÷ 9. Calories is your daily energy target in kcal, and percent is the share of those calories you want from fat. The divisor 9 is the energy in one gram of fat (about 9 kcal), compared with about 4 kcal per gram for protein and carbohydrate. The answer is rounded to a whole number of grams.

Calories must not be negative. If the percent field is empty or negative, the tool silently uses 30%, so check the number you meant. Percent values above 100 are not rejected, so keep them realistic. This is a calculation, not a recommendation: it does not tell you what share of fat is right for you.

Worked example

Daily target: 2,200 kcal, with 35% of calories from fat. Fat calories: 2,200 × 0.35 = 770 kcal. Divide by 9 kcal per gram: 770 ÷ 9 = 85.6, which rounds to 86 g of fat per day. At 30% the same diet would allow 73 g, so each 5 points of fat share is about 12 g on this calorie level.

Common mistakes

  • Dividing by 4 instead of 9 because protein and carbs are 4 kcal per gram; fat has more than twice the energy per gram.
  • Entering fat grams from a label as the percent, or the daily value percentage as a share of calories. These are different measures.
  • Leaving the percent blank and not noticing that the tool then uses 30%.
  • Using your maintenance calories when your plan is a deficit or surplus. Enter the calories you actually eat.
  • Treating the figure as a minimum or maximum. It is only the grams that match the percentage you chose.

About this calculator

This calculator converts a target fat percentage of total calories into grams, using the fact that fat provides 9 kilocalories per gram (versus 4 for protein and carbs): daily calories × fat percentage ÷ 9.

It's used by people following macro-based diets like keto or low-fat plans who need a concrete gram target rather than just a percentage, dietitians setting client meal plans, and anyone reading a nutrition label who wants to translate a percentage recommendation into an actual daily gram count.

    The percentage refers to share of total calories, and the tool converts it at 9 kcal per gram. A 2,000 kcal day at 30 percent works out to 67 g of fat. It does not split saturated from unsaturated fat, so look at food labels for that. If you leave the percentage empty, 30 is used. Which fat percentage target are you working with?
