How to use Fat Intake Calculator

Provide the calorie goal and select the nutrition objective, and the calculator will convert that energy plan into a daily fat target.

What this calculator is for

This calculator is for broad nutrition planning when you want to translate calories into grams of fat. It is especially useful when you are building a meal plan and want the fat target separated from the rest of the macros.

Tips

A fat target is not a reason to ignore fat quality; unsaturated fats and overall food pattern still matter.
Very low fat intake can make a plan hard to sustain and may crowd out important foods.
If you are following a medically directed eating plan, use those instructions first and treat this result as secondary.

Method used

This calculator converts calories into grams of fat using the standard energy value of 9 calories per gram of fat.

Fat grams = calories × fat share ÷ 9.
Suggested ranges used here are goal-based: loss roughly 20%–30% of calories, maintenance 25%–30%, gain 25%–35%.
The midpoint target uses these internal shares: lose fast 25%, lose 27%, maintain 30%, gain 27%, gain fast 25%.
