Fat Intake Calculator: Grams from TDEE (Free)

Free fat intake calculator—TDEE and fat percent for daily fat grams. Macro planning; runs in your browser.

The fat intake calculator turns maintenance calories and a fat percent into daily fat grams, with reference protein and carb splits.

How to use

  1. Enter profile and activity for maintenance kcal.
  2. Set fat as a percent of calories.
  3. Read fat grams and the macro bar; compare with the keto calculator if needed.

Example

2,200 kcal maintenance, 30% fat → ~660 kcal from fat ≈ 73 g/day (9 kcal/g, rounded).

Frequently asked questions

How many fat grams per day?

Depends on total calories and fat percent. Fat ≈ 9 kcal/g, so grams are smaller than carbs/protein at the same percent.

What fat percent should I use?

Balanced diets often use ~25–35% fat; higher fat pairs with lower carb or keto—see the keto calculator. Ask a clinician if you have lipid or pancreatic concerns.

Work with the protein calculator?

Set protein on the protein calculator, then split remaining calories here or on the macro calculator.

Is this medical advice?

No—results are for planning reference only. See clinicians for pregnancy, pediatrics, cycle disorders, or sleep conditions. Do not rely on calendar math alone for contraception.
