OpenAbout the 15-Year Fixed Mortgage Rate
The 15-year fixed mortgage is the second-most common U.S. home loan after the 30-year fixed. It pays the home off in half the time, but the trade-off is a roughly 40–60% higher monthly payment. Lenders accept lower rates on 15-year loans because the shorter term means less interest-rate risk for them — the typical spread is 80–100 basis points below the 30-year rate.
When the 15-year math wins
At today's spread (-84 bps vs 30-year), a $400,000 loan saves about $130,000 in total interest over the life of the loan when financed at 15-year terms — but costs about $1,100 more per month. The break-even is whether you'd actually invest that $1,100/month gap in something earning more than the 30-year rate. Historically, that's been a coin flip — the S&P 500 has averaged 10% (well above any recent mortgage rate), but discipline to actually invest the difference is the real variable.
Reading this chart
Today's 5.94% is well above the 2020–21 lows (under 2.5%) but in line with the long-run 15-year average. The 2022–24 spike to over 7% was driven by the same Fed tightening cycle that pushed 30-year rates near 8%. The 15-year tracks the 30-year closely with the spread varying between 60 and 110 bps depending on market conditions.
