Set a deadline before chasing a rate
Choose the month you expect to keep the mortgage, then find the highest rate that still breaks even before then. Higher fees or a shorter stay require a lower rate; a longer stay can support a higher rate.
| Situation | Useful comparison |
|---|
| Moving soon | Break-even month versus move month |
| Comparing quotes | Rate, lender fees, and credits together |
| Lower payment goal | Payment and remaining balance at exit |
Worked example
For a hypothetical $410,000 balance, a lower rate with $8,000 in fees may fail a 24-month target but meet a five-year target. Enter the same balance, costs, rate, and 24- or 60-month horizon in the calculator. The result is a decision threshold, not a prediction of available rates.
Assumptions and sources
The calculator assumes fixed-rate principal-and-interest payments. Compare actual Loan Estimates because lender credits can offset closing costs in exchange for a higher rate.
