Enter the number of divorces and the number of marriages into the Marriage Success Rate Calculator. The calculator will evaluate the Marriage Success Rate. 

Marriage Success Rate Formula

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

MSR = (M-D) / M  * 100
  • Where MSR is the Marriage Success Rate (%)
  • D is the number of divorces 
  • M is the number of marriages 

To calculate the marriage success rate, divide the difference between the number of marriages and divorces by the number of marriages, then multiply by 100.

How to Calculate Marriage Success Rate?

The following example problems outline how to calculate Marriage Success Rate.

Example Problem #1:

  1. First, determine the number of divorces.
    • The number of divorces is given as: 300.
  2. Next, determine the number of marriages.
    • The number of marriages is provided as: 1000.
  3. Finally, calculate the Marriage Success Rate using the equation above: 

MSR = (M-D) / M  * 100

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

MSR = (1000-300) / 1000  * 100 = 70.00 (%)


Example Problem #2: 

For this problem, the variables required are provided below:

number of divorces = 100

number of marriages = 500

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

MSR = (M-D) / M  * 100 = ?
