💰 THE OPPORTUNITY:
If you refinanced from 7.0% to 6.0%, you'd save $200/month on a $300k loan. Over 30 years, that's $72,000 in total savings. But only if you refinance at the RIGHT time.
What is Refinance Break-Even?
Break-even is the point where your monthly savings equal your closing costs. After break-even, you start saving money.
Example: You refinance and save $300/month. Closing costs are $6,000. Break-even = $6,000 ÷ $300 = 20 months. After 20 months, you've recovered your costs and start saving.
The Refinance Break-Even Formula
Break-Even Months = Closing Costs ÷ Monthly Savings
Example 1: Conservative Refinance
Current: 7.0% on $300k = $1,996/month
New: 6.5% on $300k = $1,896/month
Monthly Savings: $100
Closing Costs: $5,000
Break-Even: 50 months (4.2 years)
Example 2: Aggressive Refinance
Current: 7.5% on $300k = $2,098/month
New: 6.0% on $300k = $1,799/month
Monthly Savings: $299
Closing Costs: $6,000
Break-Even: 20 months (1.7 years)
When Should You Refinance?
Rule #1: Rate Drop of 0.5% or More
If rates drop 0.5% or more below your current rate, refinancing usually makes sense. Anything less than 0.5% rarely breaks even.
Rule #2: Plan to Stay 3+ More Years
If your break-even is 24 months, but you plan to sell in 2 years, DON'T refinance. You won't recover closing costs.
Rule #3: Closing Costs Under $5,000
Higher closing costs = longer break-even. If closing costs exceed $8,000, refinancing is risky unless you're saving $300+/month.
Rule #4: Don't Refinance Into a Longer Loan
If you have 25 years left on your mortgage, don't refinance into a new 30-year loan. You'll pay more interest overall.
Example: Refinancing into a 30-year loan adds 5 years of payments. Even with lower rates, total interest might be higher.
Types of Refinancing
Rate-and-Term Refinance
Change your interest rate and/or loan term. Most common type. Closing costs: $3K-8K.
Cash-Out Refinance
Borrow against your home equity. Get cash for renovations, debt payoff, etc. Closing costs: $5K-10K. Higher rates.
FHA Streamline Refinance
For FHA loans only. Minimal documentation. Closing costs: $1K-3K. Fastest option.
VA Interest Rate Reduction Loan (IRRRL)
For VA loans only. No appraisal required. Closing costs: $500-2K. Best for veterans.
Real Refinance Scenarios 2025
Scenario 1: You're Underwater (Owe More Than Home Worth)
Situation: Bought at $400k, now worth $350k. Owe $380k. Can't refinance.
Solution: Wait for home value to increase. Or do a cash-out refinance if you have equity. Or contact your lender about loan modification programs.
Scenario 2: You Have Bad Credit
Situation: Your credit dropped to 620 after a late payment. Current rate: 7.0%. New rate available: 7.5% (worse).
Solution: Wait 6-12 months for credit to improve. Then refinance. Improving credit score by 50 points = 0.5% rate improvement = $150/month savings.
Scenario 3: You're Selling Soon
Situation: Rates dropped 0.75%. You could save $225/month. But you're selling in 18 months.
Solution: DON'T refinance. Break-even is 27 months. You'll sell before recovering costs. Skip the refinance.
