When Should You Refinance?
Refinancing can save you thousands, but only when the timing and numbers are right. Learn how to evaluate whether a refinance makes sense for your situation.
Types of Refinance
Not all refinances are created equal. The right type depends on your goals, whether that is lowering your payment, paying off your mortgage faster, or accessing cash from your equity.

Rate-and-Term Refinance
The most common type. You replace your existing mortgage with a new one at a lower interest rate, a shorter term, or both. The loan amount stays roughly the same (minus what you have already paid down). This is ideal when rates have dropped since you originally purchased, or when you want to switch from a 30-year to a 15-year mortgage to pay off your home faster.
Cash-Out Refinance
A cash-out refinance replaces your existing mortgage with a larger one, and you receive the difference in cash. This is useful for major home improvements, consolidating high-interest debt, funding education, or other significant expenses. Most lenders allow you to borrow up to 80 percent of your home's value, though some programs go higher.
Streamline Refinance
If you have an FHA, VA, or USDA loan, you may qualify for a streamline refinance. These programs require minimal documentation, often skip the appraisal, and close faster than traditional refinances. The main requirement is that the refinance must result in a tangible benefit, such as a lower rate or reduced monthly payment.
The Break-Even Analysis
The break-even point is the number of months it takes for your monthly savings to exceed the total cost of refinancing. This is the most important calculation in determining whether a refinance makes financial sense.
How to Calculate Your Break-Even Point
Calculate total closing costs. Refinance closing costs typically run 2 to 5 percent of the loan amount. On a $300,000 loan, expect $6,000 to $15,000 in fees including appraisal, title insurance, origination fees, and recording charges.
Determine your monthly savings. Compare your current monthly payment to the new payment. If you currently pay $2,100 and the new payment would be $1,850, your monthly savings is $250.
Divide costs by savings. If your closing costs are $8,000 and you save $250 per month, your break-even point is 32 months. If you plan to stay in the home longer than 32 months, the refinance makes financial sense.
A general guideline: if your break-even point is under 24 months, refinancing is almost certainly worth it. Between 24 and 48 months is reasonable if you plan to stay. Beyond 48 months, carefully consider whether the savings justify the hassle and costs.
When Refinancing Makes Sense
Interest Rates Have Dropped
The traditional rule of thumb says to refinance when you can reduce your rate by at least 0.75 to 1 percent. However, even smaller reductions can be worthwhile on larger loan amounts. A 0.5 percent reduction on a $500,000 mortgage saves roughly $150 per month.
Your Credit Score Has Improved
If your credit score has increased significantly since you took out your original mortgage, you may qualify for a much better rate today, even if market rates have not changed dramatically.
You Want to Switch Loan Terms
Switching from a 30-year to a 15-year mortgage increases your monthly payment but dramatically reduces the total interest paid. Conversely, extending your term can lower your monthly payment if you need more breathing room.
You Need to Access Equity
A cash-out refinance can be a smart way to fund home improvements that increase your property value, consolidate high-interest credit card debt into a lower rate, or cover major expenses at a fraction of the cost of a personal loan.
You Want to Eliminate PMI
If your home has appreciated and you now have at least 20 percent equity, refinancing into a new conventional loan can eliminate private mortgage insurance, saving you $100 to $300 or more per month.
When Refinancing May Not Be Worth It
- !You plan to move within the next 1 to 2 years and will not reach the break-even point.
- !You are far into your loan term and have already paid most of the interest. Restarting the amortization clock could cost more in the long run.
- !Your closing costs are high relative to your monthly savings, pushing the break-even point past 4 or 5 years.
- !You would need to pay a prepayment penalty on your existing mortgage that offsets the savings.
- !Your credit score has dropped, and the new rate would be similar to or higher than your current rate.
The best way to determine if refinancing is right for you is to run the numbers with a mortgage professional who can analyze your specific situation, compare scenarios, and give you a clear recommendation.
