Break‑even math

Break‑even ≈ closing costs / monthly savings, where monthly savings is the old payment minus the new payment.

Considerations

  • Horizon: refinance only if you’ll stay beyond break‑even.
  • Fees: shop lenders; costs vary.
  • Term reset: stretching to 30 years lowers the payment but can increase total interest paid.

FAQ

What if I plan to move soon?
If you move before break‑even, the refi may not pay off.
Do I need to reset to 30 years?
Not necessarily. Consider matching remaining term to keep total interest lower.
