October 10, 2026: 30-year fixed at 7.57% vs 15-year at 7.19%—see the latest spread, costs, and payoff timelines for each term.
As of October 10, 2026, the 30-year fixed mortgage rate averages 7.57% while the 15-year fixed sits at 7.19%, producing a 38-basis-point spread according to The Right Trader. Bankrate’s same-day survey shows 7.64% and 6.85% respectively, confirming a spread between 38 and 79 basis points depending on lender. Live FRED data (October 8) lists the 30-year at 7.4%, the 15-year at 6.73%, and the 10-year Treasury at 5.22%, yielding a 218-basis-point gap between the 30-year mortgage and the benchmark Treasury.
Shorter duration reduces lender interest-rate risk and credit exposure, so borrowers pay less. The 15-year term also amortizes principal faster, lowering cumulative interest. On a $350,000 loan, total interest at 7.19% for 15 years is roughly $147,000 versus $530,000 at 7.57% over 30 years—savings of more than $380,000 despite the higher monthly payment.
| Term | Rate | Monthly P&I | Total Interest | Payoff Date |
|---|---|---|---|---|
| 30-yr | 7.57% | $2,452 | $532,720 | Dec 2055 |
| 15-yr | 7.19% | $3,162 | $219,160 | Dec 2040 |
Payments assume a $350,000 loan, zero points, and taxes/insurance excluded. Figures use exact October 10, 2026 averages.
Redfin data shows the same 38-basis-point national spread holds in most metros, but absolute levels differ. In Seattle the 30-year averages 7.61% and the 15-year 7.23%; in Atlanta the figures are 7.54% and 7.16%. Borrowers in high-cost states therefore see larger absolute dollar savings when choosing the shorter term.
The higher payment on the 15-year loan is recovered through interest savings in approximately 7.4 years on a $350,000 balance. After that point, every additional payment builds equity instead of servicing interest. Households expecting stable income and planning to stay in the home beyond the break-even window typically favor the 15-year option.
Locking a 15-year rate today secures the 7.19% average, but lenders price credit-score tiers more aggressively on shorter terms. A 740 FICO might receive a 25-basis-point reduction on the 15-year versus only 10 on the 30-year. Shoppers should run live scenarios at HomeRates.ai to compare personalized pricing before locking.
The current 38-basis-point spread is narrower than the 2021–2023 average of 55 basis points, reflecting a flatter yield curve. When the 10-year Treasury was 1.5% in 2021, the mortgage spread exceeded 70 basis points; today’s 5.22% Treasury compresses option-adjusted spreads for both products.
On October 10, 2026, the 15-year fixed mortgage rate of 7.19% saves roughly $313,000 in interest versus the 7.57% 30-year option on a $350,000 loan. Borrowers who can absorb the higher payment and intend to stay in the property past 2033 should favor the shorter term; otherwise, the 30-year preserves monthly cash flow at the cost of substantially higher lifetime interest.
