Should You Refinance? How to Run the Break-Even Math
·By Julia Kovalskiy
Refinancing can save real money — or quietly cost you it. The difference comes down to one calculation: your break-even point. As a broker licensed in Texas and Florida, here's how to decide whether a refinance is actually worth it, without the guesswork.
The break-even point, simply
Refinancing has closing costs, and it lowers your monthly payment. Your break-even point is how long it takes the monthly savings to repay those costs:
Break-even (months) = total closing costs ÷ monthly savings
If your refinance costs $4,000 and saves $200/month, you break even in 20 months. Stay in the home past that, and everything after is savings. Sell or refinance before it, and you lost money.
The rule of thumb
If you'll keep the loan well past your break-even point, refinancing usually makes sense. The bigger your monthly savings and the lower your closing costs, the faster you break even and the clearer the decision.
Reasons to refinance beyond rate
A lower rate is the classic reason, but not the only one:
- Shorten your term (30 to 15 years) to build equity and cut lifetime interest.
- Drop mortgage insurance once you have ~20% equity.
- Move from an ARM to a fixed rate for certainty. → ARMs explained
- Cash-out to consolidate higher-interest debt or fund a goal. → Cash-out vs rate-and-term
The trap to avoid: resetting your term
Refinancing a loan you're 8 years into back to a fresh 30-year term can lower your payment while increasing the total interest you pay — because you restart the clock. If cash flow is the goal, that can be fine; if payoff is the goal, consider a shorter term so you don't undo your progress. Always compare lifetime cost, not just the monthly number.
What affects your costs and savings
Your new rate, your loan-to-value (LTV) and whether an appraisal is needed, your credit, and whether you roll costs into the loan. In Texas and Florida, property taxes and insurance ride in your escrow, so make sure you're comparing apples to apples — the rate-and-term change, not the escrow.
