A 15-year fixed-rate mortgage locks your interest rate for the full 15-year term, with rates typically 0.50%–0.75% lower than 30-year loans. You’ll pay more per month, but cut total interest by 50%–65% and own your home in half the time.

If you can afford the higher monthly payment, a 15-year fixed mortgage is one of the most cost-effective ways to buy or refinance a home. Here’s what you actually gain.
15-year rates run roughly 0.50%–0.75% lower than 30-year rates. On a $400,000 loan, that’s typically a 6.0% rate vs 6.625% for 30-year — saving you tens of thousands.
On a 15-year loan, roughly 60% of your first-year payments go toward principal vs only 20% on a 30-year. You build real equity from day one instead of mostly paying interest.
Real example: $400k loan at 6.0% (15-yr) costs $208,000 in total interest. The same loan at 6.625% (30-yr) costs $522,000. That’s $314,000 saved by going 15-year.
Be mortgage-free by 50 if you buy at 35, or before retirement if you start later in life. No more housing payment is one of the most powerful ways to build long-term wealth.
A 15-year loan saves real money — but only if the higher payment fits your budget. Here’s what to look at before deciding.
Buyers with stable income who can comfortably absorb a higher monthly payment. Best fit: dual-income households, near-retirement buyers who want to be mortgage-free, refinancers with built-up equity, and high earners who’d rather pay down debt than invest the difference at uncertain returns.
At 6.0% on a 15-year: $3,376/month, $208,000 total interest. At 6.625% on a 30-year: $2,561/month, $522,000 total interest. You pay $815/month more for 15 years (extra $146,700) but save $314,000 in interest — a $167,000 net win, plus you own the home 15 years sooner.
Lenders price 15-year loans at a lower rate because the bank’s exposure window is half as long. Less time = less risk = lower rate. The spread between 15- and 30-year rates moves with bond market conditions but typically stays in the 0.50–0.75% range.
A 15-year loan doesn’t require a large down payment. You can do 15-year fixed with 3% down on conventional, 3.5% on FHA, 0% on VA, or 0% on USDA. The trade-off: a smaller down payment means a larger loan, which makes the higher 15-year monthly payment even more important to budget for.
