Enter the number of survivors and the number of people that contracted the disease into the Survival Rate Calculator. The calculator will evaluate the Survival Rate. 

Survival Rate Formula

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

SVR = #S / #D * 100

  • Where SVR is the Survival Rate (%)
  • #S is the number of survivors 
  • #D is the number of people that contracted the disease 

How to Calculate Survival Rate?

The following example problems outline how to calculate Survival Rate.

Example Problem #1:

  1. First, determine the number of survivors. 
    • The number of survivors is given as: 500.
  2. Next, determine the number of people that contracted the disease. 
    • The number of people that contracted the disease is provided as: 2000.
  3. Finally, calculate the Survival Rate using the equation above: 

SVR = #S / #D * 100

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

SVR = 500 / 2000 * 100 = 25.00 (%)


Example Problem #2: 

For this problem, the variables required are provided below:

number of survivors = 600

number of people that contracted the disease = 1800

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

SVR = #S / #D * 100 = ?
