# Cumulative Incidence Calculator

Cumulative Incidence is also known as the incidence proportion. In epidemiology, it is a measure of the frequency of disease during a period (entire lifetime). Use our cumulative incidence calculator to know the incidence proportion for a given number of an incident rate for a disease in a duration. Just enter the proper input numbers in this incidence proportion calculator and submit to calculate the cumulative incidence which is a commonly used in the measure of disease frequency.

#### Formula:

Cumulative Incidence = 1 - e^{(-IR x D)}
**Where,**
IR = Incident Rate
D = Duration
e = 2.7182818284590452
### Example:

Calculate the incidence proportion for the incident rate of disease of 5 in a period of 50 years.

#### Solution:

Cumulative Incidence = 1 - e^{(-5 x 50)}

=1
