Renal Diet Protein Limit Calculator

Work out renal diet protein limit instantly with clear inputs, formula shown and shareable results.

About Renal Diet Protein Limit Calculator

Applies the KDOQI protein targets for chronic kidney disease, which restrict protein before dialysis but raise it once dialysis begins.

Formula

KDOQI protein targets

0.55 to 0.6 g/kg/day in CKD stages 4 to 5 without dialysis; 1.0 to 1.2 g/kg/day on haemodialysis or peritoneal dialysis

Worked example

With the default values below, Renal Diet Protein Limit Calculator returns Daily protein target of 42.0. 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 2 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.

Frequently Asked Questions

Why does dialysis raise the target?

Dialysis removes amino acids and provokes catabolism, so intake must rise to prevent protein-energy wasting.

Should restriction be self-directed?

No. Low-protein diets need dietetic supervision to avoid malnutrition, and adequate energy intake is essential.
