Enter the percentage of humans under 15 years old and over 65 years old (%) and the percentage of humans in the working class, aged 15-64 (%) into the Dependency Ratio Calculator. The calculator will evaluate and display the Dependency Ratio. 

Dependency Ratio Formula

The following formula is used to calculate the Dependency Ratio. 

DR = %D / %WC * 100

  • Where DR is the Dependency Ratio (%)
  • #D is the percentage of humans under 15 years old and over 65 years old (%) 
  • #WC is the percentage of humans in the working class, aged 15-64 (%) 

How to Calculate Dependency Ratio?

The following example problems outline how to calculate Dependency Ratio.

Example Problem #1:

  1. First, determine the percentage of humans under 15 years old and over 65 years old (%). 
    • The percentage of humans under 15 years old and over 65 years old (%) is given as: 400,000.
  2. Next, determine the percentage of humans in the working class, aged 15-64 (%). 
    • The percentage of humans in the working class, aged 15-64 (%) is provided as: 1,500,000.
  3. Finally, calculate the Dependency Ratio using the equation above: 

DR = %D / %WC * 100

The values given above are inserted into the equation below and the solution is calculated:

DR = 400,000 / 1,500,000 * 100 = 26.667 (%)


Example Problem #2: 

For this problem, the variables required are provided below:

percentage of humans under 15 years old and over 65 years old (%) = 300,000

percentage of humans in the working class, aged 15-64 (%) = 2,000,000

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

DR = %D / %WC * 100 = ?
