## Compound Interest Rate Calculator Online

Compound interest is a formula used by banks and credit unions in loans and investments for calculating interest on the invested amount of money.

It is an interest you earn on the initial amount plus interest which is accumulated by previous periods.

Simple interest is somewhere different from the compound interest. It is calculated only on the initial sum of money. And compound interest is interest on the principal amount plus accumulated interest.

The formula for calculating final balance (FB) of your initial value is

FB = ID * (1 + R/CF) (T*CF).

Based on the compound interest formula, the compound interest rate is

R = CF * [(FB / ID)1/CF*T - 1].

Where

• FB - Final balance or similarly called final value or future value,
• ID - Initial Deposite or also referred as a principle amount or present value,
• R - Expected annual interest rate,
• T - Tenure or term,
• CF - Compound frequency means that the interest is how many times compounded per year.
