Refinance Break-Even Calculator

How to Use This Refinance Break-Even Calculator

1. Enter your current loan details — your remaining balance, current interest rate, and how many years are left on your mortgage. The calculator automatically computes your current monthly payment.
2. Enter the new loan terms — the interest rate and term offered by your lender. Include all closing costs and any discount points you plan to purchase.
3. Choose whether to roll costs into the loan — check the box to see how financing your closing costs affects the break-even timeline and total savings.
4. Review your results — the calculator shows your monthly savings, break-even point, and total interest saved so you can make an informed decision.
5. View the comparison table — click "Show Month-by-Month Comparison" to see exactly when cumulative savings surpass closing costs.

Understanding the Refinance Break-Even Point

The break-even point is the single most important number when deciding whether to refinance your mortgage. It tells you how many months of lower payments you need to recoup the upfront costs of refinancing. If you plan to stay in your home longer than the break-even period, refinancing will save you money. If you might move before that point, you could lose money on the transaction.

The formula is straightforward: Break-Even Months = Total Closing Costs / Monthly Payment Savings. For example, if refinancing costs you $6,000 and saves you $300 per month, your break-even point is 20 months. After month 20, every dollar saved goes directly into your pocket.

When Should You Refinance?

Financial experts generally recommend refinancing when you can reduce your interest rate by at least 0.5% to 1%, though the true answer depends on your specific numbers. A borrower with a large loan balance might benefit from even a 0.25% rate reduction, while someone with a small balance might need a larger drop to justify the closing costs. The key factors to consider are:

• Rate difference — a larger gap between your current and new rate means bigger monthly savings
• Remaining loan balance — higher balances amplify the impact of rate reductions
• How long you plan to stay — you need to stay past the break-even point to benefit
• Closing costs — lower costs mean a shorter break-even period
• New loan term — extending your term lowers payments but may increase total interest

Types of Mortgage Refinancing

Rate-and-term refinance is the most common type. You replace your existing mortgage with a new one at a lower interest rate, a different term, or both. Your loan amount stays roughly the same (plus any rolled-in closing costs). This is what this calculator models.

Cash-out refinance lets you borrow more than your current balance and pocket the difference as cash. This is useful for home improvements or debt consolidation but increases your loan amount and may come with a higher rate.

Cash-in refinance is the opposite — you bring cash to closing to reduce your loan balance, which can help you qualify for a better rate or eliminate private mortgage insurance (PMI) by reaching 20% equity.

Streamline refinance is available for FHA, VA, and USDA loans. These programs have reduced documentation requirements and may not require an appraisal, making the process faster and cheaper.

Common Refinancing Costs

Closing costs for a refinance typically range from 2% to 5% of the loan amount. On a $280,000 mortgage, that means $5,600 to $14,000. Common fees include:

• Origination fee — 0.5% to 1% of the loan amount, charged by the lender
• Appraisal — $300 to $600, required to verify your home's current value
• Title search and insurance — $500 to $1,500, protects against ownership disputes
• Recording fees — $50 to $250, charged by your county to record the new mortgage
• Attorney or escrow fees — varies by state, $500 to $1,000 is typical

Some lenders offer no-closing-cost refinances, but the trade-off is a slightly higher interest rate. This can make sense if you plan to refinance again in a few years or if you want to minimize upfront cash outlay.

Rolling Closing Costs Into Your Loan

When you roll closing costs into the new loan, you avoid paying anything out of pocket, but your loan balance — and therefore your monthly payment — increases. You also pay interest on those closing costs over the full loan term. For example, rolling $6,000 in closing costs into a 30-year loan at 5.75% adds roughly $35 to your monthly payment and costs about $6,600 in additional interest over the life of the loan.
