Key Takeaways
- Refinancing from a 30-year to a 15-year mortgage can save you thousands of dollars in total interest over the life of the loan, and 15-year loans typically come with a lower interest rate.
- The tradeoff is a significantly higher monthly payment – often 40% to 60% more than your current 30-year mortgage payment – which can strain your budget.
- According to Freddie Mac data, 15-year fixed rates have historically been about 0.50 to 0.75 percentage points lower than 30-year fixed rates, making the shorter term doubly advantageous for interest savings.
- Before refinancing, use a break-even calculator to determine how long it will take for your interest savings to offset closing costs, which typically range from 2% to 5% of the loan amount.
- This move is not right for everyone – if you cannot comfortably afford the higher monthly payment or plan to move within a few years, refinancing to a 15-year loan may not make financial sense.
Should You Refinance Into a 15-Year Mortgage?
If you currently have a 30-year mortgage and are wondering whether switching to a 15-year loan makes sense, the short answer is: it depends on your financial situation, your goals, and current interest rates. Refinancing to a 15-year mortgage can be a powerful wealth-building tool because you pay off your loan faster and pay far less interest – but it comes with a meaningfully higher monthly payment that you need to be confident you can sustain.
The best candidates for this refinance are homeowners who have stable income, have built equity in your home, can comfortably handle the increased payment, and plan to stay in their home long enough to recoup closing costs. If that describes you, consider refinancing as a way to accelerate your path to full homeownership.
What Is a 15-Year Mortgage Refinance?
A 15-year mortgage refinance is when you replace your existing mortgage – typically a 30-year loan or an adjustable-rate mortgage – with a new loan that has a 15-year term. This is a type of rate-and-term refinance, meaning you are changing the interest rate and the repayment period without borrowing additional money (unlike a cash-out refinance, where you tap into home equity for cash).
When you refinance, your new lender pays off your old mortgage, and you begin making payments on the new loan under its terms. Because the loan term is shorter, each monthly payment covers more principal (the amount you originally borrowed) relative to interest. This is what generates the dramatic interest savings.
It is worth noting that you do not necessarily need to refinance to achieve a similar effect. Some borrowers simply make extra payments on their 30-year mortgage to pay it off faster. However, refinancing to a 15-year fixed rate locks you into the shorter timeline and typically comes with a lower rate – a combination that can make it the better strategy for many homeowners.
How Much You Could Save Refinancing to a 15-Year Mortgage
The potential savings from refinancing to a 15-year loan can be substantial. Let us walk through a realistic example to illustrate.
Example Scenario
Suppose you took out a $300,000 30-year mortgage five years ago at a 6.5% fixed rate. Your remaining balance is approximately $280,000, and you have about 25 years left on the loan.
- Current 30-year mortgage: Monthly payment of approximately $1,896 (principal and interest). Over the remaining 25 years, you would pay roughly $289,000 in total interest.
- New 15-year mortgage at 5.75%: Monthly payment of approximately $2,327 (principal and interest). Over 15 years, you would pay roughly $138,900 in total interest.
- Estimated interest savings: About $150,000 over the life of the loan.
That is a difference of roughly $150,000 in interest savings, even though your monthly payment only increases by about $431. The higher monthly payment is meaningful, but the long-term savings are extraordinary. Use Wirly’s refinance calculator to run the numbers with your specific loan details.
Why Are the Savings So Large?
Two factors work in your favor simultaneously. First, 15-year mortgage rates are typically lower than 30-year rates. According to Freddie Mac’s Primary Mortgage Market Survey, the spread between 30-year and 15-year fixed rates has historically averaged between 0.50 and 0.75 percentage points. A lower interest rate means less of each payment goes to interest.
Second, you are paying for only 15 years instead of 25 or 30. Interest accumulates over time, so cutting the loan term dramatically reduces total interest paid. These two advantages compound to create substantial savings – often amounting to tens of thousands of dollars or more.
Benefits of Refinancing to a 15-Year Mortgage
Refinancing from a 30-year to a 15-year mortgage offers several key advantages beyond just the interest savings.
1. Lower Interest Rate
As noted, 15-year fixed mortgage rates are consistently lower than 30-year fixed rates. According to Freddie Mac data, this difference can save you money from your very first payment. When shopping for refinance rates, you will likely notice this spread immediately in the quotes you receive from each lender you contact.
2. Build Equity Faster
With a shorter loan term, a larger portion of each payment goes toward principal from the start. This means you build home equity at a much faster rate. Greater equity gives you more financial flexibility – whether you want to sell your home, borrow against it later, or simply enjoy the security of owing less on your property.
3. Pay Off Your Home Sooner
Owning your home free and clear in 15 years versus 25 or 30 years can be life-changing. It frees up significant monthly cash flow in retirement or other stages of life. Many homeowners time this strategy so that their mortgage is paid off before retirement or before their children start college.
4. Save Thousands of Dollars in Interest
As our example showed, the total interest paid over a 15-year loan is dramatically less than a 30-year loan. Even with a higher monthly payment, the total amount you pay for your home is significantly lower. This is one of the most straightforward ways to save money as a homeowner.
5. Potential to Eliminate Mortgage Insurance Sooner
If you are currently paying private mortgage insurance (PMI) because you had less than 20% equity when you bought your home, the faster equity growth from a 15-year loan could help you eliminate mortgage insurance sooner. According to CFPB guidance, you can request PMI cancellation once you reach 20% equity, and your servicer must automatically terminate it at 22%.
Drawbacks of Refinancing to a 15-Year Mortgage
Despite the appealing benefits, this type of refinance loan is not without drawbacks. It is critical to understand the downsides before committing.
1. Significantly Higher Monthly Payment
This is the most obvious tradeoff. A higher monthly payment can strain your budget, reduce your ability to save for other goals (like retirement or emergency funds), and leave you with less financial cushion. If your income drops or unexpected expenses arise, the higher mortgage payment is still due.
2. Closing Costs Add Up
Refinancing is not free. Closing costs typically range from 2% to 5% of the loan amount, according to the Consumer Financial Protection Bureau. On a $280,000 refinance loan, that could mean $5,600 to $14,000 in upfront costs. These costs include appraisal fees, title insurance, origination fees, and other charges. Use Wirly’s break-even calculator to determine how many months of savings it takes to recoup these costs.
3. Reduced Financial Flexibility
The extra money going toward your mortgage each month is money that cannot be invested elsewhere. Some financial advisors note that if your mortgage rate is relatively low, you might earn more by investing the difference in the stock market or retirement accounts. This is a personal decision that depends on your risk tolerance and financial goals.
4. You Are Restarting the Clock
Even though you are moving to a shorter term, you are still starting a new loan. If you have been paying your 30-year mortgage for 10 years, you only have 20 years left. Refinancing to a 15-year term means you have 15 new years of payments – which is shorter than your remaining term, but you are resetting the amortization schedule. In the early years of any new mortgage, a larger share of your payment goes to interest rather than principal.
Risks and Considerations
Because refinancing is a major financial decision, it is important to weigh these specific risks carefully.
When Refinancing Does NOT Make Sense
- You plan to move soon: If you will sell your home within a few years, you may not stay long enough to recoup closing costs through interest savings.
- Your break-even period is too long: If it takes 5 or more years to break even on closing costs, and you might move before then, the refinance could cost you money.
- You cannot comfortably afford the higher payment: Stretching your budget too thin to qualify for a 15-year mortgage is risky. A single job loss or medical emergency could put you in a difficult position.
- You have high-interest debt: Paying off credit cards or other high-interest debt may be a better use of extra money than accelerating your mortgage payoff.
Hidden Costs Borrowers Commonly Miss
- Appraisal fees: Most lenders require a new appraisal, which typically costs $300 to $600.
- Title insurance: Even if you purchased title insurance with your original mortgage, a new policy is usually required for a refinance.
- Prepayment penalties: Some existing mortgages include prepayment penalties. Check your current loan terms before applying. According to the CFPB, prepayment penalties are less common today but still exist on some loans.
- Escrow adjustments: Your new lender may require a new escrow account, meaning upfront deposits for property taxes and insurance.
Credit Score Impact
Refinancing does affect your credit score. When you apply for a refinance, the lender will perform a hard inquiry on your credit report, which can temporarily lower your credit score by a few points. According to CFPB guidance, if you shop multiple lenders within a 14- to 45-day window (depending on the scoring model), those inquiries are typically counted as a single inquiry for scoring purposes. Additionally, closing your old loan and opening a new one can temporarily affect your credit mix and average account age.
Rate Lock Risks
When you lock in your refinance rate, that lock has an expiration date – typically 30 to 60 days. If your closing is delayed beyond the lock period, you may need to pay to extend the lock or accept a different rate. Ask your lender about float-down options, which allow you to take advantage of rate drops after locking in.
Common Complaints to Watch For
According to CFPB complaint data from 2024, the most common mortgage-related complaints involved trouble during the payment process, followed by struggling to pay mortgage and issues applying for a mortgage or refinancing an existing mortgage. When selecting a lender, ask about their servicing practices, as your loan may be transferred to a different servicer after closing. Research any potential servicer’s complaint record and customer service reputation before finalizing your decision. You can check lender reviews and compare options using Wirly’s guide to the best refinance lenders.
How to Refinance to a 15-Year Mortgage
If you have weighed the benefits and risks and decided that refinancing to a 15-year mortgage is right for you, here is a step-by-step guide to the process.
Step 1: Assess Your Financial Situation
Before contacting any lender, review your finances honestly. Calculate the difference between your current mortgage payment and what a 15-year loan payment would be. Make sure you can handle the higher monthly payment without sacrificing essential savings goals like retirement contributions and emergency funds. Use Wirly’s refinance calculator to estimate your new payment.
Step 2: Check Your Credit Score and Home Equity
Your credit score plays a significant role in determining the refinance rates you qualify for. Generally, a credit score of 740 or higher will get you the best available rates. Also, determine how much equity in your home you have. Most lenders prefer at least 20% equity for the best terms, though some refinance programs accept less. You can estimate your equity by subtracting your remaining mortgage balance from your home’s current market value.
Step 3: Shop Multiple Lenders
According to the Consumer Financial Protection Bureau, getting quotes from at least three to five lenders can save you thousands of dollars over the life of the loan. Each lender may offer different refinance rates, fees, and terms. Request a Loan Estimate from each lender – this standardized form makes it easy to compare offers side by side. Remember, as noted above, rate shopping within a focused time window minimizes the credit score impact of multiple inquiries.
Step 4: Compare Loan Estimates Carefully
Look beyond the interest rate. Compare the annual percentage rate (APR), which includes fees and gives a more complete picture of the loan’s cost. Pay attention to closing costs, origination fees, and any discount points. A slightly higher rate with lower fees might be a better deal depending on how long you plan to stay in the home.
Step 5: Lock Your Rate and Complete the Application
Once you choose a lender, you will lock in your rate and submit a full application. Your lender will order an appraisal, verify your income and assets, and process the refinance loan. This typically takes 30 to 45 days. Be responsive to any requests for documentation to avoid delays.
Step 6: Close on Your New Loan
At closing, you will sign the new loan documents and pay any closing costs. Your new lender will pay off your old mortgage, and you will begin making payments on your new 15-year fixed loan according to the new schedule.
Bottom Line: Should I Refinance to a 15-Year Mortgage?
Refinancing from a 30-year to a 15-year mortgage is one of the most effective ways to save money on your home over the long run. The combination of a lower rate and a shorter term can save you tens of thousands – or even over a hundred thousand – dollars in total interest. It also helps you build equity faster and own your home outright much sooner.
However, refinancing could put you in a tight spot if the higher monthly payment strains your budget. The best approach is to run the numbers using a refinance calculator, check your break-even timeline, and compare offers from multiple lenders. If the math works and your finances are stable, a 15-year mortgage can be an excellent financial move.
If you are not sure whether the higher payment is manageable, consider a middle-ground approach: keep your 30-year mortgage but make extra payments toward principal when you can. This gives you flexibility while still reducing your total interest, though you will not benefit from the lower rate that a 15-year loan offers.
FAQ
Does refinancing from a 30-year to a 15-year mortgage hurt your credit score?
Refinancing can cause a temporary dip in your credit score due to the hard inquiry from your lender and the changes to your credit profile (closing an old account and opening a new one). However, this impact is usually small and temporary. According to CFPB guidance, if you shop for rates within a short window – typically 14 to 45 days – multiple inquiries are usually treated as a single inquiry by scoring models. Over time, making consistent on-time payments on your new loan will help your credit score recover and potentially improve.
Is refinancing from a 30-year to a 15-year mortgage a bad idea?
It is not inherently bad, but it is not right for everyone. Refinancing to a 15-year loan is a poor choice if the higher monthly payment would leave you without adequate savings, force you to take on other debt, or prevent you from contributing to retirement accounts. It also may not make sense if you plan to sell your home before reaching the break-even point on closing costs. Evaluate your complete financial picture before making this decision.
How much higher will my monthly payment be with a 15-year mortgage?
The increase depends on your specific loan amount, current rate, and the new rate you qualify for. As a general guideline, monthly payments on a 15-year loan are typically 40% to 60% higher than payments on a 30-year loan for the same balance and similar rates. For example, on a $250,000 loan, the difference might be $400 to $600 per month. Use Wirly’s refinance calculator to get a personalized estimate.
Can I refinance to a 15-year mortgage if I have an adjustable-rate mortgage?
Yes. In fact, refinancing from an adjustable-rate mortgage (ARM) to a 15-year fixed rate is a popular strategy. It eliminates the uncertainty of future rate adjustments while locking in a stable payment at a lower rate than most 30-year fixed options. If your ARM’s rate is about to adjust upward, this can be an especially smart move.
What credit score do I need to refinance to a 15-year mortgage?
Most conventional lenders require a minimum credit score of 620 for a mortgage refinance, though some programs may have different requirements. To qualify for the best 15-year fixed refinance rates, you will generally need a credit score of 740 or higher. If your score is below 740, you can still refinance, but your rate may be higher. Before applying, consider taking steps to improve your score – such as paying down credit card balances and correcting any errors on your credit report.
