How it works
Every extra dollar you pay goes straight to principal instead of accruing future interest. We run your amortization schedule twice — once at your normal payment, once with your extra amount applied each month — and compare the payoff date and total interest between the two.
Example: adding $200/month extra to a $280,000 balance at 6.5% with 27 years remaining pays the loan off about 5 years 10 months sooner and saves roughly $80,000 in interest — every extra dollar in the early years avoids decades of interest on itself.

FAQ
Yes — paying down principal early reduces the balance that future interest is calculated on, so every extra dollar saves you the interest that would have accrued on it for the rest of the loan.
The tradeoff: paying down a mortgage is a guaranteed, tax-free return equal to your rate (extra principal on a 6.5% loan reliably 'earns' 6.5%), while investing has historically averaged more over long periods but with no guarantee and real down years. Where people land usually depends on their rate, whether they have higher-rate debt to clear first, and how much they value certainty — this calculator shows exactly what the guaranteed side of that tradeoff is worth for your loan.
Not always — some servicers apply extra amounts to next month's payment rather than to principal unless you specifically mark it 'apply to principal.' The difference matters: prepaying next month's bill saves you nothing in interest. Confirm how your servicer handles it, and check your statement after the first extra payment lands.
Extra principal isn't lost when you sell — it comes back as a bigger check at closing, since you owe the bank less. What you don't get is the full multi-decade interest savings this calculator shows for keeping the loan to payoff. The shorter your stay, the smaller the interest saved, but the money was never thrown away.
