Neonatal Mortality Rate Calculator

Work out neonatal mortality rate instantly with clear inputs, formula shown and shareable results.

About Neonatal Mortality Rate Calculator

Divides deaths in the first 28 days by live births and splits infant mortality into neonatal and post-neonatal components.

Formula

Neonatal mortality

NMR = deaths in the first 28 days / live births x 1000; post-neonatal rate = (infant deaths - neonatal deaths) / live births x 1000

Worked example

With the default values below, Neonatal Mortality Rate Calculator returns Neonatal mortality rate of 7.000. 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 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

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

Frequently Asked Questions

Why separate the neonatal period?

Neonatal deaths are dominated by prematurity, intrapartum events and infection, needing different interventions from later infant deaths.

What share of infant deaths is neonatal?

Typically 60 to 75%, and the share rises as overall child mortality falls.
