Prevalence Calculator

Enter the total number of cases and the total population into the calculator to determine the prevalence of a disease.

Prevalence Formula

The following formula is used to calculate the prevalence rate of a disease.

P(%) = TC / TP *100

  • Where P(%) is the prevalence rate
  • TC is the total number of cases
  • TP is the total population size

FAQ

What is prevalence?

Prevalence is a term most often used in medicine to describe what portion of a population has a certain disease. It can however be used in any other science to describe the rate of something occurring compared to a total number of events.

Prevalence Example

How to calculate prevalence?

  1. First, determine the total number of cases.

    Measure and determine the total number of people infected. For this example we will say this number is 25.

  2. Next, determine the total population size.

    For this example we will say the population size is 100 people.

  3. Finally, calculate the prevalence.

    Using the formula above we find the prevalence is 25/100 * 100 = 25%.
