15-Year vs 30-Year Mortgage: Which Saves More in 2026?
Choosing your loan term is one of the biggest financial decisions you'll make. As of July 2026, the average 30-year fixed rate is about 6.51%, while the 15-year fixed sits near 5.83%. That gap changes the math more than most buyers expect.
The Core Trade-Off
A 15-year loan gives you a lower rate and builds equity fast — but your monthly payment is much higher. A 30-year loan keeps payments low and flexible, but you pay far more interest over the life of the loan.
Real Example: $320,000 Loan
| 30-Year @ 6.51% | 15-Year @ 5.83% | |
|---|---|---|
| Monthly (P&I) | ~$2,023 | ~$2,660 |
| Total interest | ~$408,000 | ~$159,000 |
| Interest saved | — | ~$249,000 |

When a 15-Year Makes Sense
- You have stable, high income and want to be debt-free faster.
- You want to minimize total interest paid.
- You're comfortable with a higher fixed obligation.
When a 30-Year Makes Sense
- You want lower payments and more monthly cash flow.
- You'd rather invest the monthly difference elsewhere.
- You value flexibility — you can always pay extra voluntarily.
The Middle Ground
Many buyers take a 30-year loan for flexibility, then make extra principal payments to mimic a 15-year payoff — without being locked into the higher required payment.
