About This Compound Interest Calculator

This is one of the best free compound interest calculators to help you estimate how much your investment will be worth at the end of the specified compounding period.

Simply enter your initial investment amount (principal), the interest rate details, the years for it to compound, and frequency, then hit calculate.

This will help you figure out how much money you will have over time if your money compounds yearly, monthly, weekly, daily, or otherwise.

Compound interest is the interest that is paid on your initial investment and the money that was earned from that initial investment as long as it was reinvested back into the same investment account.

For example, if my initial investment was $100, and I got 5% on my investment the first year, then reinvested that 5%, the next year I would get 5% interest on $100 + $5 I reinvested.

You can see how that would continue to grow much more than simple interest on my $100 alone. Most retirement, savings and investment accounts use compound interest, unless you remove your earnings from your investment account.

Initial Balance or Amount Invested

This is your initial investment amount or savings account balance.
