Compound Interest Calculator

Ever wondered how small savings can transform into a fortune over time? Money can grow exponentially by earning interest on the interest. This principle is named "compound interest", and many investors are using it, taking care about their financial future.

The calculation relies on the standard compound interest formula for different compounding frequencies:

$A=P{(1+\frac{r}{n})}^{nt}$

where:

$A$ — is the future value of the investment or loan, including interest

$P$ — is the initial principal amount

$r$ — is the annual interest rate, expressed as a decimal

$n$ — is the number of times interest is compounded per year

$t$ — is the time period in years

To operate the calculator, simply input an annual interest rate, then select from the available options how it's currently compounded and how it has to be compounded. The tool then outputs a new rate. For your choice, it works with the following compounding frequencies: daily, weekly, bi-weekly, semi-monthly, monthly, quarterly, semi-annual and annual.
