15-year vs. 30-year mortgage.
Lower rate and faster payoff, or lower payment and more flexibility? Side-by-side with real Colorado examples.
Pick 15-year if…
- You can comfortably afford the higher payment
- You want to be mortgage-free before retirement
- You value forced savings through faster equity build
- You're refinancing with 10+ years left on a 30-year
Pick 30-year if…
- You want the lowest possible monthly payment
- You're a first-time buyer prioritizing cash flow
- You'd rather invest the payment difference
- You want flexibility to pay extra without commitment
Side-by-side comparison
| Feature | 15-Year Fixed | 30-Year Fixed |
|---|---|---|
| Typical rate (2026) | ~0.5–0.75% lower than 30-year | Standard 30-year fixed |
| Monthly payment | Higher (faster paydown) | Lower (more flexibility) |
| Total interest paid | Roughly 1/3 of a 30-year | Significantly more interest over time |
| Equity build | Fast — most payment goes to principal early | Slow — interest-heavy in early years |
| Best for | Higher earners, refis with strong cash flow, late-career buyers | First-time buyers, growing families, anyone prioritizing flexibility |
| Risk if income drops | Higher — locked into bigger payment | Lower — you can always pay extra voluntarily |

15 vs 30-year FAQs
Is a 15-year mortgage worth it?+
If you can comfortably afford the higher payment without sacrificing retirement contributions or emergency reserves, yes — you save 60–70% in total interest. If the higher payment would stretch you thin, take the 30-year and pay extra voluntarily.
Can I pay off a 30-year mortgage in 15 years?+
Yes — there are no prepayment penalties on conforming loans. You can replicate a 15-year payoff schedule on a 30-year loan by paying extra principal. The trade-off: a real 15-year usually has a lower rate than a 30-year.
How much lower is a 15-year rate?+
Typically 0.5–0.75% lower than the 30-year fixed at the same point in time. The exact spread varies with the bond market.
Does the break-even ever favor 30-year + invest the difference?+
Mathematically, if you reliably invest the monthly payment difference at a higher after-tax return than your mortgage rate, the 30-year wins. Most people don't actually invest the difference, which is why the forced savings of a 15-year often produces better real outcomes.
Can I refinance a 30-year into a 15-year later?+
Yes — many borrowers refinance into a 15-year once their income rises or once they're 5–10 years into a 30-year. We can model the break-even on a future refinance.
