Exponential Distribution Calculator is an online Probability and Statistics tool for data analysis programmed to model the behavior of units that have a constant failure rate between events occurring continuously and independently at a constant average rate. This calculator generate the output values of Exponential distribution, Mean, Median, Variance and Standard Deviation according to the respective input values.


The exponential distribution is a simple distribution also often used in reliability engineering. Mathematically, it is used in improper situations. It is used to form the behavior of units that have a stable failure rate. The exponential distribution is a continuous probability distribution function and can be derived from the below formula.
The probability density function (pdf) of an exponential distribution is
