15-Year Fixed Mortgage Rate vs S&P 500 Price-to-Earnings Ratio (Forward)

What 15-Year Fixed Mortgage Rate measures

The 15-year fixed mortgage rate is the average interest rate on a conventional 15-year home loan. It offers a lower rate than the 30-year fixed but with higher monthly payments due to the shorter repayment term. Sourced from Freddie Mac's weekly Primary Mortgage Market Survey.

At 5.89%, the 15-year fixed rate carries a roughly 0.75 percentage point discount to the 30-year rate. Borrowers choosing the 15-year term pay significantly less in total interest over the life of the loan — typically saving over $100,000 on a $400,000 mortgage. For financial advisors and wealth managers, the spread between 15-year and 30-year rates signals how the market prices term risk. A narrowing spread suggests lenders expect rates to decline.

What S&P 500 Price-to-Earnings Ratio (Forward) measures

The forward price-to-earnings ratio measures the S&P 500 index price relative to expected earnings per share over the next 12 months. It is the most widely used valuation metric for the U.S. stock market.

The S&P 500 forward P/E at 20.3x has declined from its recent highs but remains above the 25-year average of approximately 16.5x. Markets are pricing in solid earnings growth but are no longer at 'euphoric' valuations. For executives evaluating M&A, stock compensation, or capital market activity, current valuations suggest a market that is fairly valued to modestly expensive — not cheap, but not at bubble levels either.
