Bank Interest Rate Calculator

About the Interest Rate Calculator

Whether you are walking into a bank to ask about a car loan or trying to figure out whether to put extra cash in a savings account, the most important number is rarely the one the bank advertises. Knowing your actual monthly payment and the total interest you will pay over the life of a loan, or seeing how much a savings deposit grows year by year, turns a vague rate into something you can actually plan around.

Ethiopian commercial banks typically charge between 12 and 18 percent per annum on personal and business loans, with the National Bank of Ethiopia's guidance anchoring the reference rates. For savings deposits, most banks apply monthly compounding at rates that have generally ranged from 7 to 12 percent annually. In the loan mode, this tool uses a standard amortization formula to calculate your fixed monthly payment and builds a full repayment schedule showing exactly how much of each payment goes to principal and how much goes to interest. In savings mode, it compounds your deposit monthly and shows the balance at the end of each year.

The thing that surprises many people when they see the amortization table is how much interest accumulates over a long loan term. A 15-year loan at 14 percent can cost more in total interest than the original principal. Seeing that figure before you sign is exactly why this calculator exists. Enter your loan amount, interest rate, and term, and the full picture appears immediately.
