Health Calculators

Fat Definition

Our free online fat calculator makes it as easy as pie to calculate how much fat you should have in your diet (hint: don’t eat the pie!) To find out how many fat grams you should consume each day then all you need to do is enter in your weight, height, age, gender, and physical activity.

Fat Formula:

Since about 20 to 35% of your diet should be fats, the daily fat amount needed is calculated by determining your daily caloric needs, then dividing by 9 (9 calories per gram of fat) and then multiply by .275 (the approximate percentage of your diet which should be fat).
