About MELD Score Calculator

Applies the original MELD equation to bilirubin, INR and creatinine, with the standard flooring at 1.0 and creatinine capped at 4 mg/dL.

Formula

MELD

MELD = 3.78 ln(bilirubin) + 11.2 ln(INR) + 9.57 ln(creatinine) + 6.43, values below 1 set to 1, creatinine capped at 4, score bounded 6-40

Worked example

With the default values below, MELD Score Calculator returns MELD score of 15. 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.

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

Frequently Asked Questions

What about MELD-Na and MELD 3.0?

Later versions add sodium, albumin and sex; allocation systems now use them, but the original equation is shown here.

Why cap creatinine at 4?

Patients on dialysis or with higher creatinine are assigned 4.0 to prevent renal failure dominating the score.
