When Does Refinancing Make Sense?
Refinancing replaces your existing mortgage with a new one — ideally at a lower interest rate, shorter term, or both. The decision comes down to one question: will the savings exceed the costs?
The break-even analysis is the most important calculation. Divide your closing costs by your monthly savings to find how many months until you recoup the refinance expense. If you plan to stay in the home past that point, refinancing makes financial sense.
A common rule of thumb is that refinancing is worth it if you can lower your rate by at least 0.75-1.0%. On a $280,000 loan, a 1% rate drop saves roughly $185/month or $66,600 over 30 years. Even with $8,000 in closing costs, the break-even is about 43 months.
Be cautious about extending your term. Refinancing from 22 years remaining to a new 30-year mortgage lowers payments but resets your amortization clock. You may pay more total interest even at a lower rate. When possible, match or shorten your remaining term.
Cash-out refinancing lets you borrow against your equity. It can fund home improvements or consolidate high-interest debt, but it increases your balance and risk. The interest rate is typically slightly higher than a rate-and-term refinance.
Frequently Asked Questions
When does refinancing make sense?
Refinancing typically makes sense when you can lower your rate by at least 0.5-0.75%, you plan to stay in the home long enough to recoup closing costs (past the break-even point), or you want to switch from an ARM to a fixed rate. It may also make sense to shorten your term (30yr → 15yr) if you can afford higher payments.
What is the break-even point?
The break-even point is how long it takes for your monthly savings to cover the closing costs of refinancing. If you save $200/month and closing costs are $6,000, break-even is 30 months. If you plan to move before then, refinancing may not be worth it.
How much does refinancing cost?
Closing costs for a refinance typically run 2-5% of the loan amount. On a $280,000 loan, expect $5,600-$14,000. Costs include appraisal ($300-$600), title insurance ($500-$1,500), origination fees (0.5-1%), and various processing fees.
Should I refinance to a longer term?
Refinancing from 20 remaining years to a new 30-year term lowers your monthly payment but increases total interest paid significantly. Only do this if you need the cash flow relief. If possible, refinance to the same or shorter remaining term to maximize savings.
What is cash-out refinancing?
Cash-out refinancing replaces your existing mortgage with a larger one, giving you the difference in cash. It can be useful for home improvements or debt consolidation, but increases your loan balance and monthly payment. Interest rates for cash-out refis are typically 0.125-0.25% higher.
How many times can I refinance?
There is no legal limit on how many times you can refinance. However, most lenders require a 'seasoning' period of 6-12 months between refinances. Each refinance incurs closing costs, so it only makes sense if the savings justify the expense.
