Estimate monthly payment, amortization, escrow, and early payoff savings.
Refinancing costs money upfront (closing costs) but saves money monthly (lower rate). The question is: how long until savings exceed costs?
Break-Even Months = Closing Costs / Monthly Savings
Monthly payment at 6.5%: ~$2,028
Monthly payment at 5.8%: ~$1,886
Monthly savings: $142
Break-even = $4,500 / $142 = 31.7 months (about 2 years 8 months)
If you plan to stay in the home longer than 32 months, refinancing makes financial sense.
| Rate Drop | Approx. Monthly Savings (per $100K) | Break-Even at $4K Closing |
|---|---|---|
| 0.5% | ~$30 | 133 months |
| 0.75% | ~$47 | 85 months |
| 1.0% | ~$63 | 63 months |
| 1.5% | ~$95 | 42 months |
