How to Pay Off Your Mortgage Early: 7 Proven Strategies
Your mortgage is likely the largest debt you'll ever carry — and paying interest for 30 years can cost as much as the home itself. On a $360,000 loan at 6.82%, you'll pay approximately $466,000 in total interest over 30 years. With relatively modest changes, you can cut years off that timeline and save tens of thousands. Use our Extra Payment Calculator to model any of these strategies with your exact numbers.
Strategy 1: Extra Monthly Payments Toward Principal
The simplest approach: add an extra amount each month designated for principal reduction. Even small amounts make a large difference due to compound interest working in reverse.
Impact on $360,000 loan at 6.82% — 30-year term:
• Extra $100/mo → saves ~$47,000 in interest, pays off 3.5 years early
• Extra $200/mo → saves ~$89,000 in interest, pays off 6 years early
• Extra $500/mo → saves ~$175,000 in interest, pays off 12 years early

Key: make sure your servicer applies extra amounts to principal, not to your next payment. Most servicers allow this specification online. Check for prepayment penalties — rare on modern mortgages.
Strategy 2: Switch to Biweekly Payments
Pay half your monthly amount every two weeks. With 52 weeks in a year, this produces 26 half-payments — equivalent to 13 full monthly payments instead of 12. That one extra payment per year compounds significantly.
On a $360,000 loan at 6.82%: biweekly payments save approximately $78,000 in interest and pay off the loan ~5 years and 3 months early. Use our Extra Payment Calculator with the biweekly checkbox enabled to see your exact results.
Strategy 3: Apply Windfalls to Principal
Tax refunds, bonuses, inheritance, or proceeds from asset sales — applying lump sums to principal can have outsized impact, especially early in the loan when balances are highest. A $5,000 extra payment in year 1 eliminates far more total interest than the same payment in year 20.
Strategy 4: Refinance to a Shorter Term
Refinancing from 30-year to 15-year dramatically increases your monthly payment but slashes total interest. The 15-year rate is also typically 0.5–0.75% lower.
This only makes sense if the new rate is meaningfully lower than your current rate and the payment increase fits your budget. Run break-even with our Refinance Calculator and read our refinancing mistakes guide to avoid common errors.
Strategy 5: Round Up Your Payment
If your monthly P&I is $2,247, round up to $2,300 or $2,500. This simple habit adds meaningful principal reduction each month with minimal budget impact and no specific commitment required.
Strategy 6: One Extra Payment Per Year
Make one additional full payment each year applied to principal. On a 30-year loan at 6.82%, one extra payment per year saves approximately $67,000 in interest and cuts about 4.5 years off the term. Use our Loan Comparison tool to model different extra-payment scenarios.
Strategy 7: Recast Your Mortgage
A mortgage recast means making a large lump-sum principal payment, then having the lender recalculate your monthly payment based on the new lower balance — keeping the same rate and remaining term. This lowers your payment rather than shortening your term. Unlike refinancing, there's no new loan, no credit check, no appraisal, minimal fees ($150–$500). Ask your servicer if they offer this option.
Pay Down vs. Invest: The Decision Framework
- Max tax-advantaged accounts first (401k to employer match, then IRA)
- Build 3–6 months emergency fund
- Then split between investing and extra mortgage payments based on your rate and risk tolerance
At rates above 6–7%, paying the mortgage offers a guaranteed return competitive with historical market returns. Use our Rent vs. Buy Calculator to understand the long-term financial picture of your homeownership costs.
