The Break-Even Formula
The math is simple. You take your total closing costs and divide them by your monthly savings to find out exactly how many months it takes to “break even” on your investment.
Total Closing Costs ÷ Monthly Savings = Months to Break Even
Understanding the Net Tangible Benefit (NTB): While you call it “breaking even,” compliance underwriters analyze it as a Net Tangible Benefit test. For example, federal rules for VA Streamline loans (IRRRL) mandate a maximum 36-month recoupment period for all closing costs, ensuring the new loan delivers a rapid, undeniable financial advantage.
Identifying the Three Key Variables
The 2026 Overland Park Example
If you’re moving from an older 7.25% rate down to a modern 6.25% level:
- Savings: Old $2,850 | New $2,600 = $250/month
- Costs: Lender, Title, Appraisal = $5,500
- The Result: $5,500 ÷ $250 = 22 Months
Since 22 months is well below the standard 36-month consumer safety benchmark, this refinance provides a clear “Green Light” for approval, putting real money back into your budget quickly.
