Break-Even Formula

Closing costs ($5,000) ÷ monthly savings ($200) = 25 months to break even. Stay in the home 25+ more months and refinancing wins.

Include lost tax deductions and any extended loan term in your analysis.

Rate-and-Term vs Cash-Out

Rate-and-term: replace existing loan with better terms. Cash-out: borrow more than you owe and take the difference in cash.

Cash-out only makes sense for renovations that add value or paying off 20%+ credit card debt with a plan.

When NOT to Refinance

You plan to move within break-even period. You are extending a 22-year remaining term to 30 years. Savings are under $100/month.
