Refinance Break Even Calculator
Should you refinance? Find out how long it takes to break even on closing costs and see if the monthly savings are worth it.
Understanding Break-Even Analysis
Refinancing costs money upfront—appraisal, title insurance, origination fees, recording fees. These costs range from $2,000 to $8,000 depending on your loan size and lender. You recoup this expense through lower monthly payments, but it takes time.
The break-even calculation is simple: divide closing costs by monthly savings. If you pay $4,500 to close and save $225/month, you break even in 20 months. After that, every month is pure savings. Over five years, that $225/month adds up to $13,500—minus the $4,500 you paid, netting $9,000.
The rule of thumb: if your break-even is under 24 months and you plan to stay in the home at least that long, refinancing usually makes sense. Beyond 36 months, the decision gets riskier because life changes—job transfers, family needs, market conditions—can force you to sell before you fully benefit.
When Refinancing Makes Sense
The classic refinance scenario: rates dropped significantly since you bought. If you locked in at 7% three years ago and rates are now 5.5%, refinancing on a $320,000 balance saves you $360/month. With $4,500 in closing costs, you break even in 12.5 months. That's a no-brainer if you plan to stay put for a few more years.
Refinancing also makes sense to switch loan types. Maybe you took an adjustable-rate mortgage (ARM) when rates were low, but now you want the security of a fixed rate. Or you're five years into a 30-year loan and want to switch to a 15-year to pay off faster.
Cash-out refinances can consolidate high-interest debt. If you have $30,000 in credit card debt at 18%, refinancing to pull that equity out and pay it off at 6% saves you $3,600/year in interest. But you're converting unsecured debt to secured debt—if you can't pay, you lose your house. Tread carefully.
When Refinancing Doesn't Make Sense
If you're planning to move soon, skip the refi. A 30-month break-even doesn't help if you're selling in 18 months. You'd pay $4,500 to save maybe $3,600, losing $900 in the process. The only exception is if you're moving and keeping the property as a rental—then the long-term savings still apply.
Also avoid refinancing if you're deep into your current loan. In year 25 of a 30-year mortgage, most of your payment is principal, not interest. A rate reduction saves much less because there's little interest left to cut. You might save only $50/month on a $200,000 balance, making the $3,000 closing cost hard to justify.
Watch out for no-closing-cost refinances. They sound great, but lenders bake the costs into a higher rate. You might 'save' $4,000 upfront but pay an extra 0.375% for 30 years, costing you $15,000 over the loan. These make sense only if you plan to sell or refi again within 3-5 years.
Frequently Asked Questions
What is a refinance break-even point?
The number of months it takes for your monthly payment savings to equal your closing costs. If you save $200/month and pay $4,000 in costs, you break even in 20 months.
How long should I plan to stay in the home?
Stay at least as long as the break-even period, ideally longer. If your break-even is 24 months but you're selling in 18, refinancing loses money.
What are typical refinance closing costs?
Expect 2-5% of the loan amount. On a $300,000 refinance, that's $6,000 to $15,000. Some lenders offer no-closing-cost refis but charge higher rates to compensate.
Can I roll closing costs into the loan?
Yes, but it increases your balance and monthly payment. A $300,000 refi with $5,000 rolled in becomes a $305,000 loan. You break even faster with out-of-pocket costs.
Should I refinance for 0.5% rate reduction?
It depends on the break-even period. A 0.5% drop on a $300,000 balance saves about $90/month. If costs are $3,000, you break even in 33 months. Worth it if you stay longer.
