Introduction to Probability of Death (qx) Calculator

The probability of death (qx) is a concept used in actuarial science to represent the likelihood of an individual dying within a certain period of time. The qx value is calculated by dividing the number of deaths that occurred during the period by the total exposures or individuals at risk during the same period. The resulting qx value represents the probability of an individual dying within the given time frame.

Parameter usage:

Example valid values:


Data validation

The numbers should be non-negative and the value of exposures should be greater than or equal to the value of deaths.


This calculator helps in determining the probability of death (qx) based on the number of deaths and total exposures within a specific period, which is a crucial concept in actuarial science and insurance risk assessment.
