15-Year vs. 30-Year Mortgage
A 15-year mortgage pays off the loan faster with a higher monthly payment and less total interest, while a 30-year mortgage spreads payments out for a lower monthly cost but more interest paid over the loan's life.

15-Year Mortgage
A mortgage paid off over 15 years, with a higher monthly payment but significantly less total interest paid over the life of the loan.
- Builds equity and pays off the loan much faster
- Substantially less total interest paid over the life of the loan
- Often comes with a lower interest rate than a 30-year loan
- Meaningfully higher required monthly payment
- Less monthly cash flow flexibility for other financial goals
30-Year Mortgage
A mortgage paid off over 30 years, with a lower monthly payment that frees up cash flow, though more total interest is paid over the loan's life.
- Lower required monthly payment, freeing up cash flow
- More flexibility to invest or save the payment difference elsewhere
- More total interest paid over the life of the loan
- Builds equity more slowly through scheduled payments
Which one makes sense for you?
A 15-year mortgage saves substantially on total interest and builds equity faster, but requires a meaningfully higher monthly payment. A 30-year mortgage offers more monthly flexibility and can still allow extra principal payments when cash flow allows, which is why it remains the more common choice for many buyers prioritizing payment flexibility.
Key cost factors.
- Your monthly budget and cash flow priorities
- Whether extra principal payments toward a 30-year loan are realistic for you
- How much you prioritize being debt-free sooner
- Other financial goals competing for the same monthly cash flow
Before you decide.
- What's the total interest difference between these two options over the full loan term?
- Could I make extra principal payments on a 30-year loan to shorten it if I wanted flexibility?
- How does each option's monthly payment fit my current and expected future budget?
Frequently asked questions.
Can I pay off a 30-year mortgage faster if I want to?
In most cases yes — many mortgages allow extra principal payments without penalty, which can shorten the effective payoff timeline, though it's worth confirming there's no prepayment penalty on your specific loan.
