Exponential Growth Calculator

How to use this Exponential Growth Rate Tool

This tool allows you to calculate the results of exponential growth, given any initial conditions, assuming the system is undergoing exponential growth.

It uses the standard exponential equation of the form, y(t) = y₀e^kt.

1. Enter your initial value and initial year (the year corresponding to that initial value).
   This could be the current value as it is now, and using the current year.
2. Enter the final year (the year for which you want to calculate the exponential new value at that year after exponential growth).
3. Enter the doubling time (this is the time for the value to double). If at the exponential growth rate, the value doubles every 5 years, then the doubling time is 5 years.
   If you have data points that are in exponential growth, you can also calculate the doubling time with this doubling time calculator (on this website) and then use it here.
4. Press Show Results.

Note: Year values can either be given as actual year dates e.g. 2023 to 2028 which is 5 years difference (OR) Set the current Year to an initial value like 0, with the final year some years into the future like 5.
When setting the Initial and Final Years, both 2023 to 2028, and 0 to 5 will give the same results, as the year range for either is 5 years.

Note: The final calculated value is rounded to 3 decimal places.
