What does paying extra buy?

A recurring overpayment, a one-off, or both, against interest saved and months removed from the term.

The overpayment

Earlier is worth more — the same money removes more interest the longer it has to work.

Before overpaying, check there is no prepayment penalty on your note, and that any emergency fund and higher-rate debt are dealt with first. Money that goes into a mortgage is hard to get back out.

Illustrative only. No rate on this page is available anywhere and no result is a quote, an approval or a commitment. Defaults are round numbers chosen so the arithmetic is legible, not figures anybody is offering. Taxes, insurance, association dues and mortgage insurance vary enormously between towns, buildings and lenders.

Assumptions on this page: every extra dollar is applied to principal immediately, the rate is fixed, and no escrow, tax or insurance is included — this is principal and interest only. Real servicers vary in how they apply extra money, and some require it to be labelled as a principal reduction rather than an early payment.
