This calculator determines how long it will take to pay off your loan with a fixed monthly payment. It's useful for existing loans where you know your current balance and interest rate but want to understand exactly when you'll be debt-free.
Each month, your payment is split: first, interest on the current balance is charged, then the remainder reduces the principal. As the principal drops, each month's interest charge decreases slightly, allowing more of your payment to go toward principal — accelerating payoff over time.
Extra principal payments have a compounding benefit. They reduce the balance on which interest is charged next month. Over time, even $50/month extra can shave months or years off your loan and save hundreds in interest.
