15-Year vs 30-Year Mortgage: Which Should You Choose?
The loan term you choose affects your monthly budget, your total interest cost, and how quickly you build equity — and the right answer depends on more than just which number looks smaller on paper.
Here's a clear look at how these two common mortgage terms actually compare, so you can weigh the tradeoff for your own situation.
The core tradeoff
A 15-year mortgage pays off the loan in half the time of a 30-year mortgage, which means a larger portion of each payment goes toward principal from day one. This gets you to full ownership faster and saves a substantial amount in total interest.
A 30-year mortgage spreads the same loan amount over twice as many payments, which lowers the monthly payment significantly — often making it the only realistic option for buyers who need to keep monthly housing costs manageable.
Interest rates usually favor the shorter term
Lenders typically offer a lower interest rate on 15-year loans compared to 30-year loans, since the lender's risk is reduced over a shorter repayment period. This compounds the interest savings even further beyond just the shorter timeline.
What you give up with a 15-year term
The higher monthly payment is the obvious tradeoff, but it's worth thinking about less obvious effects too. A larger required payment leaves less monthly flexibility for other financial goals — retirement contributions, an emergency fund, or simply weathering an unexpected expense.
Some financial planners recommend a middle path: take the 30-year loan for its lower required payment and lower monthly risk, then voluntarily pay extra toward principal when your budget allows. This gives you 30-year flexibility with the option to pay off closer to a 15-year timeline if your finances stay strong.
A side-by-side example
On a $320,000 loan, a 30-year term at 6.5% runs about $2,022/month and accrues roughly $407,000 in total interest over the life of the loan. The same $320,000 at a 15-year term and a typically lower rate of around 6.0% runs about $2,701/month — a noticeably higher payment — but accrues only around $166,000 in total interest, a difference of over $240,000.
