How to calculate Fat Calories on a food label

Fat calories

Here’s what the food label tells us:

  • There are 12 grams of fat per serving in this product.
  • There are 110 calories from fat per serving.

Note: There are 9 calories in 1 gram of fat.

Here’s the math:

12 grams of fat x 9 calories per gram = 108 calories from fat

Why does it say 110 Calories from Fat?

Calories from fat are rounded to the nearest 10 calorie increment (if over 50 calories). Therefore 108 calories is rounded to 110 calories from fat on the label.

The following box is sometimes shown on a food label. It tells you there are 9 calories in 1 gram of fat…always.
