Your Refinance Trigger Rate
Calculate your trigger rate: the rate at which refinancing produces a break-even under 30 months given your likely remaining tenure. If your current rate is 7.0%, closing costs are $9,000, and you’ll stay 7 years: monthly savings need to be at least $300 ($9,000 ÷ 30 months). On $380K, $300 savings requires a rate of approximately 6.3%. Set your alert for rates approaching 6.3%.

|---|---|---|
| 7.5% | $300,000 | 6.65% |
