Enter the total number of deaths and the total population at risk into the Mortality Rate Calculator. The calculator will evaluate the Mortality Rate. 

Mortality Rate Formula

The following two example problems outline the steps and information needed to calculate the Mortality Rate.

MOR = D / P * 1000
  • Where MOR is the Mortality Rate (deaths per 1000 people)
  • #D is the total number of deaths 
  • P is the total population at risk 

To calculate a mortality rate, divide the total number of deaths by the total population at risk, then multiply by 1,000 to express as deaths per 1000 people.

How to Calculate Mortality Rate?

The following example problems outline how to calculate Mortality Rate.

Example Problem #1:

  1. First, determine the total number of deaths.
    • The total number of deaths is given as: 500.
  2. Next, determine the total population at risk.
    • The total population at risk is provided as: 100,000.
  3. Finally, calculate the Mortality Rate using the equation above: 

MOR = #D / P * 1000

The values provided above are inserted into the equation below and computed.

MOR = 500 / 100,000 * 1000 = 5 (deaths per 1000 people)

Example Problem #2: 

For this problem, the variables required are provided below:

total number of deaths = 60

total population at risk = 100,000

Test your knowledge using the equation and check your answer with the calculator..

MOR = #D / P * 1000 = ?
