15-Year Fixed Mortgage:
Pay Off Faster. Pay Less Interest.
Half the term, a lower rate, and dramatically less total interest. The 15-year fixed is the fastest path to owning your home outright, Mortgages by Channing closes them every day.
The Basics
What Is a 15-Year Fixed Mortgage?
A 15-year fixed mortgage is a home loan with a locked interest rate and a 180-month repayment term. Like a 30-year fixed, your rate never adjusts, but you pay the loan off in half the time, build equity significantly faster, and pay a lower interest rate because the lender's exposure period is shorter.
The trade-off is a higher monthly payment. Because you're retiring the same loan balance in half the time, each payment is larger than a 30-year equivalent. That higher required payment is the main qualification hurdle, but for borrowers whose income supports it, the 15-year fixed is the most cost-effective fixed-rate mortgage available.
Ideal Borrower
Who the 15-Year Fixed Is Best For
The 15-year fixed isn't for everyone, the higher required payment means you need the income to support it comfortably. But for the right borrower, it's a significant financial advantage.
15-Year Fixed Wins When You...
- Have strong, stable incomeThe higher monthly payment requires solid income. Lenders will qualify you on the 15-year payment, so DTI must work at that level.
- Want to minimize total interest paidShorter term + lower rate = dramatically less total interest over the life of the loan.
- Are refinancing an existing loanIf you're 8 to 12 years into a 30-year, refinancing to a 15-year may keep your payoff timeline similar while cutting your rate.
- Are approaching retirement and want to be mortgage-freeA 15-year timed to your retirement date is a common and powerful strategy.
- Want to build equity quickly for a future moveFaster equity means more proceeds when you sell, and more down payment for the next home.
Consider 30-Year Instead When You...
- Need the lower payment to qualifyIf the 15-year payment pushes your DTI over the limit, you can only use a 30-year.
- Have variable or commission-based incomeThe higher required payment leaves less room in slow months. The 30-year gives you flexibility.
- Plan to invest the payment difference at higher returnsIf you can reliably earn more on investments than your mortgage rate, the 30-year + invest strategy wins mathematically.
- Are buying a starter home you'll sell in 5 to 7 yearsIf you're not staying long enough to realize the interest savings, the higher payment doesn't pay off.
The Savings
How Much Interest Does a 15-Year Fixed Save?
The interest savings on a 15-year vs. 30-year are substantial, often six figures on a typical loan. Here's the full comparison across common loan amounts, assuming a 0.625% rate advantage for the 15-year (a common spread).

The savings are real, but the payment difference is too
On a $300,000 loan, the 15-year saves $256,080 in total interest, but your monthly payment is roughly $700 higher than the 30-year equivalent. The question is whether that $700/month creates more value as mandatory mortgage payoff or as investable capital. Mortgages by Channing will run both scenarios with actual numbers so you can make the call with complete information.

By Loan Program
15-Year Fixed Across Every Loan Type
The 15-year fixed term is available across all major loan programs, the program determines your eligibility and down payment, the term determines your payment and payoff speed.
Conventional 15-Year Fixed
The most common use case, a strong-income buyer or refinancer who wants to maximize equity and minimize total cost. PMI rules are the same as 30-year conventional. See conventional loan guide →
FHA 15-Year Fixed
FHA's 15-year fixed has one major advantage: if you put 10%+ down, MIP drops off after 11 years, vs. life of loan on a 30-year FHA. For buyers who can handle the payment, this accelerates the path to eliminating mortgage insurance. See FHA loan guide →
VA 15-Year Fixed
Zero down, no mortgage insurance, and a 15-year payoff timeline, an extremely powerful combination for eligible veterans. The funding fee is the same regardless of term. See VA loan guide →
15-Year as a Refinance Tool
Many borrowers refinance from a 30-year into a 15-year once income grows or existing equity makes the payment manageable. This is especially powerful at year 8 to 12 of a 30-year, your payoff date barely changes but your rate drops and equity builds much faster. See rate-and-term refinance guide →
