Enter your weight and age into the calculator to determine your recommended daily sugar intake in grams. This calculator provides an estimate based on general dietary guidelines.

Daily Sugar Intake Formula

The following formula is used to calculate the recommended daily sugar intake.

SI = W * 0.8

Variables:

  • SI is the daily sugar intake (grams)
  • W is the weight of the individual (pounds)

To calculate the daily sugar intake for individuals aged 4 years and older, multiply the weight in pounds by 0.8. For children under 4 years old, a fixed intake of 25 grams is recommended.
