Why such a small extra payment saves so much

Every extra dollar goes straight to principal โ€” and every dollar of principal you kill today stops earning interest against you for the entire remaining life of the loan. That's why extra payments early beat extra payments late.

Tip: even one extra payment per year (divide your monthly payment by 12 and add that) typically cuts 4โ€“6 years off a 30-year mortgage. Check with your lender that extra payments are applied to principal, not "next month's payment."
