Example
- $250,000 at 7% (25 yrs left) → 5.5% (30 yrs), $4,000 closing → $1,766.95 → $1,419.47; saves $347.48/mo; break-even 12 months
- $300k loan, 7%→5%, same 28-yr term, $5k closing cost → Payment $2,038.83 → $1,660.72 (save $378.10/mo); break-even in 14 months
Formula
Break-even = closing costs / monthly savings. Compare the remaining term, not just the rate — stretching a 25-year loan into 30 years can lower the payment while raising total interest. Refinancing usually pays off only if you stay past the break-even point.
