15-Year vs 30-Year Mortgage: Which Is Right for You?
Choosing between a 15-year and 30-year mortgage is one of the biggest financial decisions you will make. Both have clear advantages, and the right choice depends on your income, goals, and risk tolerance.
The 30-year mortgage is America's default for good reason: lower monthly payments provide breathing room in your budget. On a $280,000 loan at 6.75%, the 30-year payment is $1,817/month. This frees up $546/month compared to the 15-year option — money that could go to retirement accounts, emergency savings, or other investments.
The 15-year mortgage wins overwhelmingly on total cost. At 6.0% (rates are typically 0.5-0.75% lower), the payment is $2,363/month — but total interest is only $145,000 vs $374,000 for the 30-year. That is $229,000 in savings. You also build equity twice as fast and own your home free and clear in 15 years.
The hidden advantage of 15-year loans is the lower interest rate. You are not just paying for fewer years — you are paying a lower rate on a faster-declining balance. This double benefit compounds into dramatic savings that a 30-year loan with extra payments cannot fully replicate.
A practical middle ground: take the 30-year loan but make payments as if it were a 15-year. You get the lower required payment as a safety net, with most of the interest savings. The risk is that without the forced discipline of a 15-year payment, many homeowners never actually make those extra payments consistently.
Frequently Asked Questions
How much do you save with a 15-year mortgage?
On a $280,000 loan, a 15-year at 6.0% costs $145,000 in total interest vs $374,000 for a 30-year at 6.75%. That's $229,000 in savings — nearly the price of a second home. The trade-off is higher monthly payments: $2,363 vs $1,817.
Is a 15-year mortgage worth the higher payment?
If you can comfortably afford the higher payment without sacrificing retirement savings or an emergency fund, yes. You build equity faster, pay dramatically less interest, and own your home in half the time. If the payment strains your budget, a 30-year with extra payments offers flexibility.
Are 15-year mortgage rates lower?
Yes, typically 0.5-0.75% lower than 30-year rates. Lenders charge less because shorter loans carry less risk. This rate advantage compounds the savings — you're paying less interest on a faster-declining balance at a lower rate.
Can I get a 20 or 25-year mortgage instead?
Yes, some lenders offer 10, 15, 20, and 25-year terms. A 20-year mortgage is a good middle ground — lower payments than 15-year but significantly less interest than 30-year. Not all lenders advertise these, so ask specifically.
What if I take a 30-year and make extra payments?
This gives flexibility. You can make 15-year-sized payments when affordable and drop back to minimum when tight. The downside: you need discipline, and your rate is higher (30-year rate vs 15-year). If you consistently make extra payments, a 15-year loan saves more due to the lower rate.
Who should choose a 15-year mortgage?
Ideal for: buyers with stable high income, those planning to stay long-term, people approaching retirement who want to own outright, and anyone who prioritizes total cost over monthly cash flow. Not ideal for: first-time buyers stretching on price, or those with variable income.
