## What is Compound Interest?

Compound interest is a financial concept that refers to the interest earned or paid on both the initial principal (the initial amount of money) and any accumulated interest from previous periods. In other words, it’s interest that is calculated on the initial amount of money, as well as on any interest that has already been earned or incurred.

## All Formulae Related to Compound Interest

**Future Value (A) of an Investment or Loan with Compound Interest:**The future value of an investment or loan that compounds interest is calculated using the formula:A = P * (1 + (r/n))^(n*t)Where:- A is the future value of the investment or loan, including both the principal and interest.
- P is the principal amount (the initial amount of money).
- r is the annual interest rate (expressed as a decimal).
- n is the number of times that interest is compounded per year.
- t is the number of years the money is invested or borrowed for.

**Principal (P) Calculation:**To find the principal amount (the initial amount of money) needed to achieve a specific future value (A) with compound interest, you can rearrange the formula as follows:P = A / [(1 + (r/n))^(n*t)]**Interest Earned (I) Calculation:**The interest earned on an investment with compound interest can be calculated using the formula:I = A – PWhere I is the interest earned, A is the future value, and P is the principal amount.**Effective Annual Rate (EAR) Calculation:**The effective annual rate is a measure of the true annual interest rate when interest is compounded multiple times within a year. It is calculated as follows:EAR = (1 + (r/n))^n – 1Where EAR is the effective annual rate, r is the nominal annual interest rate, and n is the number of times interest is compounded annually.
