Daily fat intake target in grams, from your total calories and a target fat percentage.

Equation used
Fat grams = dfracCalories × Fat%9

Frequently Asked Questions

Why divide by 9 to get fat grams?

Fat provides about 9 calories per gram — more than double protein or carbohydrate — so dividing the calories allotted to fat by 9 converts that amount into grams.

What is the AMDR range shown (20–35%)?

That's the Acceptable Macronutrient Distribution Range for fat as a share of total daily calories — a general population guideline, not a target tailored to your specific goals.

How is this different from the Macro Calculator?

The Macro Calculator splits your calories across protein, carbs and fat together (requiring all three percentages to add to 100%). This page focuses on fat alone against a single AMDR benchmark.
