Rate calculator


    To understand basic risk you need to know the number of events and the number of the population in which the events occurred.

  • When you want to know:
  • the incidence per 100,000: divide the events by the population and multiple by 100,000
  • the number of persons needed in a population to have 1 incident: divide the population by the events
  • the percent of events in a population: divide the events by the population and multiple by 100

  • p -the number of persons needed in a population to have 1 incident:
