## Compound interest rates formula

Compound interest is when a bank pays interest on both the principal (the original amount of money)and the interest an account has already earned.

Compound interest is the interest you earn each year that is added to your principal, so that the balance doesn't merely grow, it grows at an increasing rate. It is one of the most useful concepts in finance. It is the basis of everything from developing a personal savings plan to banking on the long-term growth of the stock market.

To calculate compound interest in Excel, you can use the FV function. This example assumes that \$1000 is invested for 10 years at an annual interest rate of 5%,  because the compound interest formula is an exponential equation and solving exponential equations with different bases requires the use of logarithms.

## 16 Jul 2018 The average credit card interest rate in the summer of 2018 was 17% APR. If you owe \$5,000 in credit card debt and make only the 4% minimum

compound interest formula.

Multiply the principal amount by one plus the annual interest rate to the power of the number of compound periods to get a combined figure for principal and compound interest. Subtract the principal if you want just the compound interest. Compound Interest Rate Formula = P (1+i) t – P. Where, P = Principle. i= Annual interest rate. t= number of compounding period for a year. i = r. n = Number of times interest is compounded per year. r = Interest rate (In decimal) The second way to calculate compound interest is to use a fixed formula. The compound interest formula is ( (P* (1+i)^n) - P), where P is the principal, i is the annual interest rate, and n is the number of periods.
