- Bounded inputs: bilirubin 4.2, INR 1.6, creatinine 1.9, sodium 130, albumin 3.
- MELD(i) = 10 x [0.957 ln(1.9) + 0.378 ln(4.2) + 1.120 ln(1.6) + 0.643] = 23.3.
- MELD 3.0 = 1.33 (female) + 4.56 ln(4.2) + 0.82 x 7 - 0.24 x 7 x ln(4.2) + 9.09 ln(1.6) + 11.14 ln(1.9) + 1.85 x 0.5 - 1.83 x 0.5 x ln(1.9) + 6 = 28.9633.
- Rounded to the nearest whole number and held to the 6-40 range used for allocation: 29.

What the meld score calculator calculates
Computes the MELD, MELD-Na and MELD 3.0 scores for chronic liver disease from bilirubin, INR, creatinine, sodium and albumin, applying the published laboratory floors, the creatinine ceiling and the dialysis rule, and reports the three-month waiting-list mortality band for the score.
How to use this meld score calculator
Enter Version, Total bilirubin, INR and Serum creatinine. Score updates as you type, and “Use a worked example” loads checked figures you can adjust. Change one figure at a time to see what drives the result.
How the result is worked out
Open “How this is worked out” beside the result for the step-by-step calculation behind Score, Version and Before rounding and capping.

Original MELD: bilirubin 4.2, INR 1.6, creatinine 1.9 example
With Version: meld, Total bilirubin: 4.2, INR: 1.6, Serum creatinine: 1.9, the calculator returns MELD(i): 23.3, Score: 23. This example is checked against an independent source in the test suite.
What you can compare
Change one input at a time to see how it affects Score, Version and Before rounding and capping. The inputs you can vary are Version, Total bilirubin, INR, Serum creatinine, Serum sodium and Serum albumin.
Understanding Score, Version and Before rounding and capping
A prognostic score used for organ allocation, not a diagnosis or a prognosis for an individual. The mortality figures are waiting-list mortality from a historical OPTN cohort. Interpretation and any transplant decision belong to a hepatology team.
Results are general information, not financial, tax, legal, medical or engineering advice. Check any decision that matters with a qualified professional.

Frequently asked questions
How do I calculate my MELD score?
Computes the MELD, MELD-Na and MELD 3.0 scores for chronic liver disease from bilirubin, INR, creatinine, sodium and albumin, applying the published laboratory floors, the creatinine ceiling and the dialysis rule. Open “How this is worked out” beside the result to see each step for your own figures.
What is a good MELD score for your liver?
Computes the MELD, MELD-Na and MELD 3.0 scores for chronic liver disease from bilirubin, INR, creatinine, sodium and albumin, applying the published laboratory floors, the creatinine ceiling and the dialysis rule. On this page it is computed from Version, Total bilirubin and INR and shown as Score, Version and Before rounding and capping.
What is the life expectancy for someone with a MELD score of 15?
On the figures this page opens with — total bilirubin 4.2 mg/dL, INR 1.6 and serum creatinine 1.9 mg/dL — the score is 29. No single number fits everyone: change any figure above and the answer updates as you type, with each step of the arithmetic beside it.
What is the typical MELD score cut-off for liver transplants?
It needs Version, Total bilirubin, INR, Serum creatinine, Serum sodium and Serum albumin. Nothing else is required, and the figures stay in your browser.
What information do I need for the meld score calculator?
You need Version, Total bilirubin, INR, Serum creatinine, Serum sodium, Serum albumin, Sex and Dialysis twice in the past week, or 24 hours of CVVHD. The page opens with default figures that give score of 29, so you can see the scale before entering your own.
What does this meld score calculator show?
It shows Score, Version, Before rounding and capping, MELD(i), Three-month waiting-list mortality, Mortality band, Bilirubin used and INR used, with the working and any warnings for your entries.
