Compare monthly payments and total interest on 15- and 30-year mortgages at this week's rates, plus a middle path that gives you the flexibility of both.
Choosing a mortgage term looks like a small decision on the application. In practice, it shapes your monthly budget for years and the total interest you'll pay by a large amount. The 30-year fixed is by far the most common choice in the U.S., but the 15-year fixed has real advantages for buyers who can afford it.
This guide compares the two using this week's average rates, then covers how to decide, including a middle path that many buyers overlook.
This week's rates
According to Freddie Mac's Primary Mortgage Market Survey for the week of October 22, 2026, the average 30-year fixed rate was 7.32% and the average 15-year fixed rate was 6.68%. Fifteen-year loans usually carry lower rates because the lender's money is tied up for less time. You can see the history on our rates page.
The numbers side by side
Take a $369,630 loan, 10% down on the national median sales price of $410,700 (Q2 2026):
| 30-year fixed | 15-year fixed | |
|---|---|---|
| Rate | 7.32% | 6.68% |
| Monthly principal & interest | $2,539 | $3,257 |
| Total interest if held to term | $544,447 | $216,551 |
The 15-year loan costs about $717 more per month but saves roughly $327,895 in interest over the life of the loan. Neither figure includes taxes, insurance or mortgage insurance.
The case for a 30-year mortgage
- Lower required payment. That makes it easier to qualify and to keep your budget flexible.
- Room for other goals. The monthly difference can go toward retirement savings, an emergency fund or other priorities.
- Optional prepayment. Most mortgages today don't have prepayment penalties (check your Loan Estimate), so you can pay extra when you want to and fall back to the required payment when money is tight.
- Inflation. Your fixed payment stays the same while incomes and prices generally rise over time, so it tends to become a smaller share of your budget.
The case for a 15-year mortgage
- Lower rate and far less interest. You pay less for the money and for less time.
- Faster equity. More of each payment goes to principal from the start, so you build ownership quickly. That can matter if you plan to move or need to borrow against your home later.
- Debt-free sooner. Owning your home outright in 15 years can be a big advantage heading into retirement or other life changes.
- Built-in discipline. The higher payment forces savings you might not make on your own.
The risks of each
The risk of a 15-year loan is cash flow. The required payment is much higher, and if your income drops or a big expense hits, you can't lower it. Stretching to afford a 15-year payment while leaving no emergency fund can backfire.
The risk of a 30-year loan is cost and temptation. You'll pay far more interest if you only make the minimum payment for 30 years, and it's easy to let the "extra" monthly money disappear into spending.
The middle path: 30-year loan, 15-year payments
Many buyers take a 30-year loan for flexibility and then voluntarily pay extra principal each month, aiming to pay it off much sooner. You won't get the 15-year loan's lower rate, so it costs more than a true 15-year loan, but you keep the safety of a lower required payment.
Worked example: On the same $369,630 loan at 7.32%, paying the 15-year loan's monthly amount of $3,257 instead of the required $2,539 would pay off the loan in about 16 years and 2 months instead of 30 years, and save about $282,303 in interest. That's a bit slower and costlier than a true 15-year loan because of the higher rate, but you keep the option to pay less. If you lose income, you can drop back to the required payment without penalty. Our extra payments guide shows how to make sure extra money goes to principal.
How to decide
Ask yourself these questions:
- Does the 15-year payment fit comfortably after an emergency fund, retirement contributions and other savings? If not, the 30-year is likely the better fit.
- How stable is your income? Variable or uncertain income argues for the lower required payment.
- How long will you keep the home? If you expect to move in a few years, the interest savings of a 15-year loan are smaller, though you'll still have more equity when you sell.
- Will you actually prepay? If you'll reliably send extra each month, the middle path works. If not, a 15-year loan enforces it.
Common questions
Can I refinance from a 30-year to a 15-year later? Yes, if you qualify and rates and costs make sense at the time. Refinancing has closing costs, so it's not free flexibility.
What about 20-year or 10-year loans? Many lenders offer other fixed terms. A 20-year loan can be a middle ground with a payment between the 15 and 30 and a rate that's often in between too. Ask lenders to quote several terms.
Does a shorter term help me qualify? Usually the opposite: the higher payment raises your debt-to-income ratio, so you may qualify for a smaller loan with a 15-year term.
Practical takeaways
- 15-year loans have lower rates and far lower total interest, but much higher payments.
- 30-year loans offer flexibility and a lower required payment, at a higher total cost.
- A 30-year loan with voluntary extra payments is a flexible middle path.
- Keep an emergency fund and retirement savings on track whatever term you choose.
- Compare terms with your own numbers in the mortgage calculator, and keep property taxes in mind using your state page.
