The 15-year vs. 30-year decision is really a question about what you value more: paying less interest overall, or keeping your monthly payment — and your options — flexible.
The case for the 15-year mortgage
- Much less interest paid over the life of the loan.
- Faster equity buildup, which matters if you might sell or tap equity later.
- A lower interest rate. Lenders typically price 15-year loans below 30-year loans — in Freddie Mac’s mid-September 2026 survey, the national 15-year average was about 6.26% versus about 6.95% for the 30-year.
- Forced discipline. The higher payment builds wealth on autopilot.
Choose the 15-year if the higher payment still leaves you with a healthy emergency fund and room in your budget. If the payment would leave you cash-strapped, the “savings” aren’t worth the stress.
The case for the 30-year mortgage
- A lower monthly payment, which is easier to qualify for and easier to live with.
- Flexibility. You can invest the difference, build savings faster, or handle life’s surprises.
- An inflation hedge. You’re paying future dollars that are worth less than today’s.
- You can still pay it like a 15-year. Nothing stops you from making extra principal payments on a 30-year loan when money is good — and dropping back to the minimum when it isn’t.
How to decide
Ask yourself: after the higher 15-year payment, would I still have 3–6 months of expenses saved and a comfortable budget? If yes, the 15-year is a wealth-building machine. If no — or if you value flexibility, plan to move within several years, or would rather invest the difference — the 30-year is the smarter fit.
Either way, compare the total interest and the monthly payment side by side with your lender before you decide. The right mortgage is the one that fits both your math and your life.
