What Is Compound Interest?
Compound interest means earning interest on both your original money and the interest already earned. Over long periods, compounding can cause investment growth to accelerate.
Compound Interest Formula
The basic compound interest formula is A = P(1 + r/n)^(nt), where
P is the starting amount, r is the annual rate,
n is the number of compounding periods per year, and t is time in years.

Frequently Asked Questions
Is this financial advice?
No. This calculator provides educational estimates only and is not financial advice.
Does the currency selector convert money?
No. The currency selector changes the display symbol only. It does not perform exchange-rate conversion.
Is monthly compounding better than annual compounding?
All else being equal, more frequent compounding usually produces a slightly higher result.
Why include inflation?
Inflation reduces purchasing power. Inflation adjustment estimates what a future amount may feel like in today's money.
Can compound interest make me a millionaire?
It can help, but the result depends on starting amount, contributions, time, returns, fees, taxes and inflation.
