It shows how making extra principal payments — monthly, yearly, or one-time — shortens your loan term and cuts the total interest you pay.
The Complete Guide
Paying extra toward principal is one of the few guaranteed returns in personal finance: you save the exact interest rate on your loan, tax-free. On a 7% mortgage, an extra payment effectively earns 7%, which is hard to beat with low-risk alternatives.
Timing magnifies the benefit. Because early balances are largest, extra payments in the first decade of a 30-year loan save dramatically more interest than the same payments made later. Front-load if you can.
Confirm your lender applies extra funds to principal, not to future payments, and check for any prepayment terms. The calculator assumes every extra dollar reduces the balance immediately, which is how most modern mortgages work.
How the Calculator Works
The calculator runs your loan on two tracks: the standard schedule and a schedule with your extra principal applied. It compares the two to show the months saved and the interest saved by paying ahead.
Frequently Asked Questions
Is it better to pay extra monthly or once a year?
Both help. Monthly extra payments reduce the balance a little sooner each period, while a lump sum has a larger immediate effect. The calculator lets you compare the two for your loan.
Should I pay extra or invest instead?
Paying extra guarantees a return equal to your mortgage rate. Investing may earn more but carries risk. Many borrowers split the difference, especially when the mortgage rate is high.
