Use this guide when you are deciding between faster payoff and refinancing

• Use this page when your real decision is whether to keep the current loan and pay it down faster or replace it with a new loan.
• If you already know you want to stay on the current loan, move next to extra mortgage payments.
• If the refinance path is the frontrunner, move next to refinance break-even for the cost-recovery math.

How to compare

1. Model extra payments on the current loan.
2. Model a refinance with realistic closing costs.
3. Compare total interest and cash outlay over your horizon.
4. Account for the time you expect to keep the loan.

Data to gather

• Current balance, rate, and remaining term.
• Estimated refinance rate and total closing costs.
• Planned time in the home or loan horizon.
• Any prepayment penalties or lender credits.

Common mistakes

• Using a refinance payment without including closing costs.
• Comparing different horizons (30 years vs 5 years).
• Ignoring that extra payments keep your existing term.

Break-even check

• Estimate monthly savings from the refinance.
• Divide closing costs by monthly savings for a break-even month.
• Compare break-even to your planned horizon.
• Recheck if rates or fees change.

When extra payments win

• You expect to move or refinance before break-even.
• Closing costs are high relative to the rate drop.
• You can make consistent principal-only extras.
• Liquidity is more important than a new loan.

Scenario notes

• Compare the same horizon for both options, not the full term.
• Include escrow resets and upfront costs in the refinance cash flow.
• Stress test with a smaller extra payment to confirm affordability.

Decision inputs

• Expected rate and closing cost for the refinance.
• Monthly extra you can sustain without stress.
• Time horizon for staying in the home.
• Prepayment penalties or escrow changes.
• Cash needed for other goals in the next 12 months.
