30-year vs 15-year mortgage: which should you choose?

When you pick a mortgage, one big choice is the loan term — usually 30 years or 15 years. The right answer depends on your budget and goals. This page compares them in plain language so you can decide.

The trade-off is simple: a 30-year loan has lower payments but more total interest, while a 15-year loan has higher payments but big interest savings. Let's look closer.

Quick answer

A 30-year mortgage has lower monthly payments but you pay more interest over time. A 15-year mortgage has higher monthly payments but a lower rate and far less total interest, and you own your home in half the time. Choose 30-year for flexibility and a lower payment; choose 15-year if you can afford more and want to save on interest.

What this means

The loan term is how long you have to pay off the loan.

30-year: Payments are spread over more years, so each one is smaller.
15-year: Payments are squeezed into fewer years, so each one is bigger — but you finish much sooner and pay less interest.

A 15-year loan also usually comes with a lower interest rate, which adds to the savings. But the higher payment is not for everyone.

How it works (side-by-side example)

Here is a rounded example on a $500,000 loan. These are illustrations, not quotes.

The 15-year saves a large amount of interest, but the monthly payment can be significantly higher.

Benefits

30-Year:
Lower monthly payment.
More room in your budget.
Easier to qualify.
You can still pay extra to finish sooner.
15-Year:
Lower interest rate.
Far less total interest.
Own your home in half the time.
Build equity faster.

Potential drawbacks (the honest part)

30-Year:
Much more total interest.
Slower equity growth.
Longer to be debt-free.
15-Year:
Higher monthly payment.
Less budget flexibility.
Harder to qualify.
Less cash free for other goals.

A middle path: 30-year with extra payments

You do not have to choose a 15-year loan to pay off faster. You can take a 30-year loan for the lower required payment, then pay extra when you can. This gives flexibility with the option to finish early. See Pay Off Faster (Term Change).

Common mistakes

1Choosing 15-year without budget room. A higher payment can strain your finances.
2Assuming 30-year is "wasteful." It offers flexibility you can use wisely.
3Forgetting you can pay extra. A 30-year loan can be paid off early.
4Ignoring the rate difference. 15-year loans often have a lower rate.
5Stretching to afford 15-year. Leaving no cushion is risky.
6Not comparing total interest. The long-term difference can be large.
Good questions

Frequently asked questions

It depends. A 15-year saves interest and builds equity faster, but the payment is higher. A 30-year is more flexible.

Next steps

Decide based on your budget first

Decide based on your budget first. If a 15-year payment is comfortable and you want to save interest, it can be powerful. If you value flexibility, a 30-year loan with optional extra payments is a great middle path.
