How this calculator works
Every loan boils down to three numbers: how much you borrow, the rate, and how long you take to repay. This loan payment calculator turns those three inputs into the two numbers that matter for your budget — the monthly payment and the total interest you will pay over the life of the loan. It works for personal loans, student loans, business loans and any other amortizing debt: each payment is split into interest (charged on the remaining balance) and principal, so early payments are mostly interest and later ones mostly principal.
Two insights usually surprise people. First, stretching the term drops the payment but explodes total interest — doubling the term can nearly double what you pay in interest. Second, even small extra payments attack principal directly and can shave months off the schedule. The balance chart shows the payoff curve so you can see exactly when the loan starts shrinking fast. Use the calculator to compare offers (a lower rate beats a longer term almost every time), to check whether a payment fits your budget before you sign, and to plan extra payments that cut interest.
