MELD Calculator (for ages 12 and older)

The Model for End Stage Liver Disease (MELD) predicts survival for patients with advanced liver disease.

Did the patient have dialysis at least twice in the past week?



  • This version of the MELD calculator includes United Network for Organ Sharing (UNOS) modifications of the original model.
  • The MELD utlizes log scale calcuations and thus any value less than 1 is automatically given a lower limit value of 1 to prevent generating a negative score.
  • The upper limit of serum creatine is capped at 4; in addition, if the patient had dialysis at least twice in the past week, the value for serum creatinine will be automatically adjusted to 4.0.

3-Month Mortality Based on MELD Scores

The estimated 3-month mortality is based on the MELD score highlighted in yellow above.

  • 40 or more -- 71.3% mortality
  • 30-39 -- 52.6% mortality
  • 20-29 -- 19.6% mortality
  • 10-19 -- 6.0% mortality
  • <9 -- 1.9% mortality
