A 15-year mortgage pays the loan off in half the time, usually at a lower rate, and costs dramatically less interest over the life of the loan. The price is a much higher monthly payment. A 30-year mortgage keeps the payment lower and gives you flexibility, at the cost of more total interest. The right choice depends less on the math than on what you would do with the difference.
The trade in one paragraph
On the same loan amount, the 15-year payment is substantially higher than the 30-year payment, often 40% to 60% higher depending on rates. In exchange, you build equity much faster and pay a fraction of the total interest. Lenders also typically price 15-year loans at a lower rate than 30-year loans, which compounds the savings.
Who the 15-year suits
- Buyers whose payment is comfortable even at the higher amount, with reserves left over.
- People within 15 to 20 years of retirement who want the house paid off when the paycheck stops. See Getting a Mortgage in Retirement.
- Refinancers who already have years into a 30-year loan and do not want to restart the clock.
- Disciplined savers who would not invest the difference anyway.
Who the 30-year suits
- First-time buyers, whose budget is tight and whose income is likely to grow.
- Anyone whose qualifying ratio is close to the limit. The higher 15-year payment counts against you in underwriting, which can shrink the price you qualify for. See Debt-to-Income Ratio Explained.
- Self-employed borrowers and commission earners with variable income, who value a lower required payment in a slow month.
- People who will actually invest the difference, or who need cash for a business, children's education, or reserves.
The option most people never consider
Take the 30-year loan and pay it like a 20- or 15-year loan when you can. Most mortgages allow extra principal payments without penalty. You lose the lower 15-year rate, but you keep the right to drop back to the lower payment in a bad month. For many households, flexibility is worth more than the rate difference.
Also consider a 20-year or 25-year term, which many lenders offer. It sits between the two on payment and interest.
Questions to answer before you choose
- If the higher payment hit in a month when income dropped, would you be fine?
- Do you have six months of expenses in savings after closing? If not, build that before you shorten the term.
- Are you carrying high-interest debt? Paying a card off beats prepaying a mortgage.
- Are you capturing any employer retirement match? Skipping a match to pay down a mortgage is usually a bad trade.
- How long will you keep this home? If you plan to sell in five years, the total-interest comparison over fifteen or thirty years is mostly irrelevant. What matters is the equity built and the cash spent while you own it.
I will run both terms, and a prepaid 30-year, side by side with your real numbers. The answer is usually obvious once you see the payment next to your actual budget.
Why ask me
- I answer the question before I sell you anything. If renting, waiting or a different program is the better move, I will say so.

- Every program under one roof. Conventional, FHA, VA, jumbo, and non-QM options like bank statement, DSCR and asset-based loans, so the program fits you instead of the other way around.
