Protein Intake Calculator

Estimate daily protein grams from your body weight and a clearly labelled planning factor.

Estimated daily protein
Enter your weight to calculate.

For healthy adults, EFSA's population reference intake is 0.83 g/kg/day. Higher options here are planning factors, not a claim that everyone needs that amount. Requirements can differ with age, pregnancy, illness, kidney disease, sport and overall energy intake.

Protein target guide

The calculator keeps the arithmetic transparent: weight in kilograms × the selected grams-per-kilogram factor. Use the reference option for a population-level baseline, or a higher factor if that is the intake you are deliberately planning around.
