How is refinance break-even calculated?
When closing costs are paid in cash: months ≈ cash costs ÷ monthly payment savings. Rolled-in costs use a different principal path and do not use that cash break-even formula.
Why might a shorter new term raise my payment?
Spreading principal over fewer months usually raises the monthly payment even if the rate falls, while total interest can still drop under the model.
