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 can cut over 6 years off the loan and save tens of thousands in interest.
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.
