How to use this calculator

  1. Enter the known values in the units shown. Results update as you type.
  2. Where results are editable, change one to solve backwards. Lock a value to hold it fixed.
  3. Use the worked example to check the method. Reset restores the starting fields.

Results are estimates for planning and education. Confirm rates, taxes, fees, and legal requirements with the relevant institution or a qualified professional before making a financial decision.

Formula and method

Revenue increasing from 1,000 to 1,210 over two equal periods has total growth of 21% and a compound growth rate of 10% per period.

Total change (%) = 100(final / initial − 1); compound rate (%) = 100[(final / initial)^(1 / periods) − 1]

Assumptions and limitations

  • Starting revenues and the elapsed period count must be positive; ending revenues may be zero. Rates cannot be below −100% for nonnegative ending revenue.
  • The compound rate is a constant mathematical equivalent, not the sequence of actual period-to-period growth rates. Periods are years only if the endpoints and period count use years.
  • Both sections are independent. A −100% rate or a zero ending value can make some reverse calculations non-unique or undefined; enter the known endpoints and period count for the forward rate.
  • Use matching periods, currency and quantity units. Currency selectors use captured fixed exchange rates, not live rates.

Common questions

Is the compound rate always annual?

No. It is per entered period. Use elapsed years to calculate an annualized rate.

Can revenues decline?

Yes. For example, 1,000 falling to 500 is a total decline of 50%.

References

Require nonnegative final revenues and rates no lower than minus 100 percent while preserving positive starting revenue and elapsed periods.
