Enter the number of divorces and marriages into the calculator to determine the divorce rate. This calculator can also evaluate any of the variables given the others are known.

Divorce Rate Formula

The following formula is used to calculate the divorce rate. 

DR = (D / M) * 100

Variables:

  • DR is the divorce rate (%)
  • D is the number of divorces in a given year
  • M is the number of marriages in the same year

To calculate the divorce rate, divide the number of divorces in a given year by the number of marriages in the same year. Multiply the result by 100 to convert the ratio into a percentage. This percentage represents the divorce rate.

What is the Divorce Rate?

A divorce rate is a statistical measure that represents the number of divorces that occur annually, typically expressed as a ratio or percentage of the total population or married population. It is used to gauge the prevalence of divorce in a specific region, country, or globally, and can be influenced by various factors such as changes in law, societal norms, economic conditions, and more. High divorce rates often indicate a society where ending marriages is more socially acceptable or common, while low rates may suggest the opposite.

How to Calculate Divorce Rate?

The following steps outline how to calculate the Divorce Rate.

  1. First, determine the number of divorces (D) in a given year.
  2. Next, determine the number of marriages (M) in the same year.
  3. Next, gather the formula from above = DR = (D / M) * 100.
  4. Finally, calculate the Divorce Rate.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
