How is compound interest computed

It makes a sum of money grow at a faster rate than simple interest because you will earn returns on the money you invest, as well as on returns at the end of every compounding period. Interest is the cost of borrowing money, where the borrower pays a fee to the lender for the loan.

In contrast, compound interest is based on the principal amount and the interest that accumulates on it in every period. There is basically no difference between monthly and annual interest and no difference when it comes to withdrawing capital.

The Truth in Lending Act TILA requires that lenders disclose loan terms to potential borrowers, including the total dollar amount of interest to be repaid over the life of the loan and whether interest accrues simply or is compounded. Another method is to compare a loan's interest rate to its annual percentage rate APR , which the TILA also requires lenders to disclose. The APR converts the finance charges of your loan, which include all interest and fees, to a simple interest rate.

A substantial difference between the interest rate and APR means one or both of two scenarios: Your loan uses compound interest, or it includes hefty loan fees in addition to interest. Even when it comes to the same type of loan, the APR range can vary wildly between lenders depending on the financial institution's fees and other costs. You'll note that the interest rate you are charged also depends on your credit. Loans offered to those with excellent credit carry significantly lower interest rates than those charged to borrowers with poor credit.

Depositors also benefit from compound interest when they receive interest on their bank accounts, bonds, or other investments.
