Two ways to pay off your mortgage early

Extra monthly payments are the most flexible approach — add any amount to your regular payment and it goes directly to principal. Even $100/month makes a meaningful difference over time.

Lump-sum payments are ideal when you receive a bonus, tax refund, or inheritance. A single $10,000 payment early in the loan can eliminate years of interest.

Both strategies work best when your mortgage allows prepayment without a penalty — the vast majority of modern mortgages in the U.S. do. Check your loan documents to confirm. Learn more in our buyer's guide →
