Enter the number of employees that stayed during the period and the total number of employees at the start of the period into the Retention Rate Calculator. The calculator will evaluate the Retention Rate. 

Retention Rate Formula

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

RTR = #ES / #TE *100

  • Where RTR is the Retention Rate (%)
  • #ES is the number of employees that stayed during the period 
  • #TE is the total number of employees at the start of the period 

How to Calculate Retention Rate?

The following example problems outline how to calculate Retention Rate.

Example Problem #1:

  1. First, determine the number of employees that stayed during the period. 
    • The number of employees that stayed during the period is given as: 500.
  2. Next, determine the total number of employees at the start of the period. 
    • The total number of employees at the start of the period is provided as: 600.
  3. Finally, calculate the Retention Rate using the equation above: 

RTR = #ES / #TE *100

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

RTR = 500 / 600 *100 = 83.33 (%)


Example Problem #2: 

For this problem, the variables required are provided below:

number of employees that stayed during the period = 700

total number of employees at the start of the period = 1000

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

RTR = #ES / #TE *100 = ?
