A lower rate is only part of the refinance decision. You need to know when the monthly savings pay back the closing costs, and whether you will still have the loan by then. A refinance can lower the payment and still cost more if fees are high or the clock resets for too long.
How break-even works
Use this formula: closing costs divided by monthly savings. For example, a $320,000 loan dropping from 6.5% to 5.75% might save about $160 per month. With $7,200 in closing costs, the break-even point is roughly 45 months.
When refinancing looks strong
- Your rate drops by more than 0.75%.
- You expect to stay 5+ years.
- Your break-even point is under 24 months.
When to skip it
- You plan to sell soon.
- You refinanced recently.
- The new loan adds many years to the payoff timeline.
Costs people miss
- Prepayment penalties.
- Escrow resets.
- Rate lock fees.
Frequently asked questions
What closing costs should I include in my break-even calculation?
Include origination fees, discount points, appraisal, title insurance, escrow setup, and any prepayment penalties on the current loan. Total costs typically run 2-5% of the loan amount.
How long do most people stay in their home after refinancing?
The median homeowner stays about 8-10 years after refinancing. If your break-even is under 3-4 years and you plan to stay, the math often works.
Does refinancing restart my 30-year clock?
Yes, unless you choose a shorter term. If you refinance into a new 30-year loan with 22 years left, you add 8 years to the payoff schedule. Include that extra interest in the decision.
Can I negotiate closing costs on a refinance?
Yes. Origination fees and some third-party fees are negotiable. You can also ask about a no-closing-cost refinance, where costs are built into the rate or loan balance.
Methodology note: Break-even divides total closing costs by monthly savings, then compares cumulative interest and costs over the selected planning horizon.
