Glycaemic Load Calculator

Work out glycaemic load instantly with clear inputs, formula shown and shareable results.

About Glycaemic Load Calculator

Multiplies glycaemic index by available carbohydrate per serving and divides by 100, which scales the index by the amount actually eaten.

Formula

Glycaemic load

GL = glycaemic index x available carbohydrate per serving / 100; low is 10 or below, medium 11 to 19 and high 20 or more

Worked example

With the default values below, Glycaemic Load Calculator returns Glycaemic load per serving of 16.500. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
  • This is an estimate for general information and not professional medical advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why is load better than index?

Watermelon has a high index but so little carbohydrate per serving that its load is low.

What daily load is typical?

Around 100 is a common average; below 80 is generally considered a low glycaemic load diet.
