How We Calculate Sugar Calories

Learn about the science behind sugar calories

How We Calculate

Each gram of sugar contains 4 kilocalories (kcal). To find the calories from sugar, simply multiply the grams of sugar by 4.

  • Calories from sugar: grams × 4
  • Percentage of total calories: (calories from sugar / total daily calories) × 100

If you don't know your total daily calorie intake, you can leave it blank.

Why Limit Sugar Calories?

Consuming too many calories from sugar can increase your risk of obesity, diabetes, and other health issues. The World Health Organization recommends limiting free sugars to less than 10% of total energy intake, and ideally below 5% for additional health benefits.
