Web17 dec. 2024 · Article SummaryXTo calculate doubling time, first multiply your growth rate by 100 to convert it to a percentage. If you don’t know your growth rate, you can derive it by subtracting your past quantity from your current quantity and dividing the result by your past quantity to get it before you multiply it by 100. WebFor example, if a population starts out at 1000 individuals and grows by 5% each year, the equation is y(t) = 1000(1.05) t. Given a growth rate of R%, the growth factor is B = 1 + R/100. If you wish to find the doubling time or tripling time of the population, you only need to know the value of B or R. Doubling Time
