Enter the number of women using contraception aged 15-49 and the total number of women aged 15-49 into the Contraceptive Prevalence Rate Calculator. The calculator will evaluate the Contraceptive Prevalence Rate. 

Contraceptive Prevalence Rate Formula

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

CPR = WU / TW * 100

Variables:

  • CPR is the Contraceptive Prevalence Rate (%)
  • #WU is the number of women using contraception aged 15-49 
  • #TW is the total number of women aged 15-49 

To calculate the contraceptive prevalence rate, divide the number of women using contraception aged 15-49 by the total women population in that age range, then multiply by 100.

How to Calculate Contraceptive Prevalence Rate?

The following steps outline how to calculate the Contraceptive Prevalence Rate.


  1. First, determine the number of women using contraception aged 15-49. 
  2. Next, determine the total number of women aged 15-49. 
  3. Next, gather the formula from above = CPR = #WU / #TW * 100.
  4. Finally, calculate the Contraceptive Prevalence Rate.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

number of women using contraception aged 15-49 = 5,000

total number of women aged 15-49 = 12,000

CPR = #WU / #TW * 100 = ?
