How does inflation impact compound interest calculations?

Inflation reduces the real rate of return on investments with compound interest. While the nominal interest rate remains fixed, inflation causes the purchasing power of money to decline over time.

For example, if the inflation rate is 5% and the nominal interest rate on an investment is 8%, the actual rate of return is only 3% (8% - 5% inflation). Use an online compound interest calculator for faster calculations.

By factoring in inflation, the continuous compounding formula will calculate the growth of an investment's future purchasing power rather than just its future nominal value.
