15‑Year vs 30‑Year Refinance: Which Is Better?
Deciding between a 15‑year and a 30‑year refinance depends on your financial goals, monthly cash flow, and how long you plan to keep the home. This guide explains what each option is, when each makes sense, benefits and drawbacks, typical costs, a step‑by‑step process, common mistakes to avoid, and a short FAQ to help you choose the right path.
What it is and when it makes sense
What a 15‑year refinance is
A 15‑year refinance replaces your current mortgage with a new loan that amortizes over 15 years. Interest rates are typically lower than longer terms, and you pay off the principal much sooner.
What a 30‑year refinance is
A 30‑year refinance sets a new loan amortized over 30 years. Monthly payments are lower than a 15‑year loan at the same balance, which improves cash flow but increases total interest paid over the life of the loan.
When each makes sense
- 15‑year makes sense if you can comfortably afford higher monthly payments, want to minimize interest paid, build equity faster, and plan to stay in the home long term.
- 30‑year makes sense if you need lower monthly payments, prefer flexibility for savings and investments, or plan to move in the near term and want to maximize cash flow.
Benefits and drawbacks
15‑year benefits
- Much lower total interest—often tens of thousands less over the life of the loan.
- Faster equity building and homeownership paid off sooner.
- Lower interest rates compared with 30‑year loans, which increases interest savings.
15‑year drawbacks
- Significantly higher monthly payments—can strain cash flow.
- Less flexibility for emergencies or other financial priorities unless you maintain a strong emergency fund.
30‑year benefits
- Lower monthly payment improves cash flow and budgeting flexibility.
- Allows redirecting extra cash to higher‑return investments or paying off higher‑interest debt.
- Easier qualification for borrowers with lower income or higher debt‑to‑income ratios.
30‑year drawbacks
- Higher total interest over the life of the loan.
- Slower equity growth.
Costs and fees
Refinancing comes with closing costs similar to an original mortgage. Typical items include:
- Origination fees and lender fees
- Appraisal, title search, title insurance
- Underwriting and credit report fees
- Prepaid interest, escrow setup fees, recording fees
- Points (optional) to buy a lower rate
Expect total closing costs of roughly 2% to 5% of the loan amount (varies by lender and loan). You can sometimes roll costs into the loan or ask the seller to pay, but that increases the balance. Always compare APR and run a break‑even analysis: how long until monthly savings or interest savings justify the upfront cost?
Step‑by‑step process to decide and refinance
- Clarify your goal: lower payment, pay off faster, reduce total interest, or access equity.
- Check your current mortgage details: remaining balance, remaining term, current interest rate, and any prepayment penalty.
- Estimate affordability: use a budget to determine the maximum new monthly payment you can comfortably support.
- Get rate quotes from multiple lenders for both 15‑ and 30‑year options, including loan estimates showing closing costs and APR.
- Run numbers: compare monthly payments, total interest, and break‑even points. Use an amortization schedule or online calculator.
- Choose the loan that fits your goals and apply: submit documentation (income, assets, credit info).
- Lock the rate if you’re satisfied, complete appraisal and underwriting, review the Closing Disclosure, and attend closing.
- After closing, verify the old loan is paid off and set up payments on the new loan. Maintain or increase emergency savings to handle higher payments if choosing 15‑year.
Common pitfalls to avoid
- Ignoring closing costs: a lower rate doesn’t always equal savings if you factor in heavy fees.
- Not considering cash flow: choosing a 15‑year because it “saves interest” without ensuring you can sustain the payment.
- Resetting the amortization clock unknowingly: refinancing down to a new 30‑year after already paying years on a mortgage can increase lifetime interest.
- Not shopping lenders: small rate differences or fee waivers can change which option is better.
- Using a cash‑out refinance to buy consumer goods: extracting equity increases balance and interest costs, reducing the benefit of a shorter term.
Short FAQ
Q: Will a 15‑year refinance always save me money?
A: It usually saves substantial interest over time, but only if you can afford the higher monthly payment and plan to stay in the home long enough to justify closing costs. Crunch the numbers first.
Q: How long does it take to recoup refinancing closing costs?
A: That depends on the difference in monthly cost or savings and the size of closing costs. For a rate‑reducing refinance, divide the closing costs by the monthly savings to find the break‑even months. For switching to a 15‑year (with higher payment), the “payback” is measured in long‑term interest saved rather than monthly savings.
Q: Can I refinance to a 15‑year if I don’t have much equity?
A: Possibly, but lenders have equity and loan‑to‑value (LTV) requirements. FHA, VA, and some conventional programs have different limits. If LTV is high, you may need mortgage insurance or a larger down payment to qualify.
Q: Can I later switch from a 30‑year to a 15‑year if my finances improve?
A: Yes—many homeowners refinance multiple times. If your income grows or you pay down other debts, you can refinance into a shorter term later. Just weigh the new closing costs and potential interest savings.
Choosing between a 15‑year and a 30‑year refinance is a personal decision balancing monthly affordability and long‑term interest savings. Run the numbers, consider your financial priorities, and shop lenders to find the best fit.
