15-Year vs 30-Year Mortgage: Which Should You Choose?
When you take out a fixed-rate mortgage, one of the biggest choices is the term — most commonly 15 or 30 years. It sounds like a small detail, but it shapes your monthly payment, the total interest you'll pay, and how much financial flexibility you keep. Neither is "better" in the abstract; the right answer depends on your budget and goals.
The core trade-off
A 30-year mortgage spreads the loan over more payments, so each monthly payment is lower and easier to fit into a budget. A 15-year mortgage packs the same loan into half the time, so payments are higher — but you pay far less interest overall and own your home outright much sooner. Fifteen-year loans also typically come with a slightly lower interest rate, which adds to the savings.
| 15-year | 30-year | |
|---|---|---|
| Monthly payment | Higher | Lower |
| Total interest paid | Much less | More |
| Interest rate | Usually lower | Usually higher |
| Equity builds | Faster | Slower |
| Budget flexibility | Less | More |
When a 30-year makes sense
The lower required payment is the 30-year's biggest strength. It leaves room in your budget for emergencies, retirement contributions, or other goals, and it qualifies you for a larger loan if you need it. A popular middle-ground strategy is to take the 30-year loan for its low required payment, then voluntarily pay extra toward principal in good months — capturing some of the interest savings of a shorter term without being locked into the higher payment when money is tight.
When a 15-year makes sense
If you can comfortably afford the higher payment, the 15-year is hard to beat on pure cost. You'll pay dramatically less interest, build equity quickly, and be mortgage-free in half the time — appealing if you want to retire without a house payment or free up cash flow down the road. The key word is comfortably: the higher payment is mandatory every month, so it should fit your budget with room to spare.
Questions to ask yourself
- Can I afford the 15-year payment even in a lean month, with an emergency fund intact?
- Am I already maxing out retirement accounts, or would lower payments help me invest more?
- How long do I plan to stay in this home?
- Do I value being debt-free sooner, or keeping monthly flexibility?
There's no universally correct answer — a disciplined saver might do better investing the payment difference from a 30-year loan, while someone who values certainty may prefer the forced savings of a 15-year. Running both through a calculator with your real numbers makes the trade-off concrete.
