You locked in a 30-year mortgage at 7.2% in late 2024 on a $350,000 loan. Rates have dropped to 6.0%. Your lender is quoting $6,500 in closing costs to refinance. Here is exactly how to decide whether that makes financial sense — and when you would break even.
The Break-Even Calculation
Refinancing replaces your existing mortgage with a new one at a lower rate. You pay closing costs upfront and recover them over time through lower monthly payments. The break-even point is when your cumulative savings equal what you spent.
At 7.2% on a $350,000 loan, your monthly principal and interest payment is $2,381. At 6.0%, it drops to $2,098. That is a monthly savings of $283.
Divide the closing cost by the monthly savings:
$6,500 ÷ $283 = 23 months to break even.
If you plan to stay in the home at least 23 months (less than 2 years), the refinance pays for itself. If you move before then, you spend $6,500 and never recover it.
Monthly Savings at Different Rate Drops (on $350K loan)
| Current Rate | New Rate | Rate Drop | Monthly Savings | Break-Even at $6,500 |
|---|---|---|---|---|
| 7.2% | 6.75% | 0.45% | $103 | 63 months |
| 7.2% | 6.50% | 0.70% | $167 | 39 months |
| 7.2% | 6.25% | 0.95% | $230 | 28 months |
| 7.2% | 6.00% | 1.20% | $283 | 23 months |
| 7.2% | 5.75% | 1.45% | $336 | 19 months |
A half-point rate drop saves $167/month but takes 39 months to break even on $6,500 in costs. That is fine if you plan to stay 4+ years. A 1.2-point drop cuts the break-even to under 2 years — much more forgiving.
How Closing Costs Affect the Math
Closing costs vary by lender and loan size. On a $350,000 refinance, typical costs break down as:
- Origination fee: $1,750-$3,500 (0.5-1% of loan amount)
- Appraisal: $400-$600
- Title search and insurance: $600-$1,200
- Escrow/settlement fee: $400-$700
- Prepaid interest: $300-$600 (days between closing and first payment)
- Recording fee: $50-$150
The $6,500 estimate in this scenario is toward the high end of a no-points refinance. "No-closing-cost" refinances exist — the lender covers costs in exchange for a rate 0.25-0.375% higher. On a $350K loan, that higher rate costs ~$60/month. If you refinance again in 2-3 years, no-cost can be smarter.
Rate-and-Term vs. Cash-Out Refinance
A rate-and-term refinance simply replaces your current loan with a new one at a lower rate. The goal is to lower your payment or shorten the loan term (say, from 30 years to 15 years). This is what the break-even math above covers.
A cash-out refinance replaces your loan with a larger loan, and you receive the difference in cash. Example: your home is worth $450,000 and you owe $320,000. You refinance to a new $380,000 loan and receive $60,000 in cash, now at the new interest rate.
Cash-out refinances make sense when:
- You need funds for a high-value home improvement that increases property value
- Your current equity is substantial and the rate differential is favorable
- Alternative financing (personal loan, HELOC) would cost significantly more
The risk: you convert equity back into debt. A HELOC at 8.5% on $60,000 costs $5,100/year in interest. A cash-out refinance that raises your rate from 6.0% to 6.25% on a $350K loan costs an extra $885/year — much cheaper, but now $380,000 is secured against your home rather than $350,000.
When Rate-and-Term Refinancing Fails the Math
Three situations where refinancing rarely makes sense:
1. You are deep into your current loan. A 30-year mortgage front-loads interest. After 7 years, you are finally paying down principal faster. Refinancing into a new 30-year resets the clock. Even if your rate drops from 7.2% to 6.0%, you could pay significantly more total interest over the full new term. Run the total interest comparison, not just the monthly payment.
2. Your break-even is beyond your expected stay. Transferring jobs, growing family, retirement timing — if you expect to sell within 24-36 months, only a very large rate drop (1.5%+) makes break-even math work.
3. Prepayment penalties on your current loan. Rare on conventional loans but common on some portfolio loans and certain FHA/VA products. Add any penalty to your closing cost calculation.
What "No-Points" Really Means
Mortgage points (also called "discount points") let you buy down your rate at closing. One point costs 1% of the loan amount. On $350,000, one point is $3,500 and typically buys a 0.25% rate reduction.
At 6.0%, paying one point to get 5.75% saves $58/month. Break-even on $3,500: 60 months (5 years). That only makes sense if you plan to stay more than 5 years — and can tolerate putting that $3,500 into closing costs rather than your savings.
The right move: run the break-even with and without points, at your expected hold period. The Refinance Calculator does this comparison in one step.
