Buying a home is one of life’s most exciting milestones, but it’s not something you do on a whim. Taking out a mortgage is a huge decision that’ll significantly impact your financial future. There are many factors to consider, including term duration. Should you go for a 15- or 30-year mortgage? How are they different?

A 30-year fixed-rate mortgage has been the typical path American homebuyers have taken for generations. However, opting for a 15-year term instead can save you thousands over the length of the term, and may be the better choice for some aspiring homeowners. Here’s everything you need to know about 15- vs 30-year fixed-rate mortgages, including the pros and cons, to help you decide.

15- vs 30-Year Fixed Mortgage: Which One Should You Choose?

15- and 30-year mortgages are fixed-rate loans with similar structures. Their monthly principal and interest rates never change regardless of market conditions, offering borrowers stability. While they have fixed rates in common, they also have some notable differences, the main one being their term.

Aside from having a shorter term, 15-year mortgages also have lower interest rates, meaning you’ll pay less interest over the loan’s period. However, you’ll have higher monthly payments due to the shorter loan term. Meanwhile, 30-year mortgages can give you lower monthly payments, but you’ll pay more interest at a higher rate.

Who Should Consider A 15-Year Mortgage?

A 15-year mortgage is an attractive option for those who want to save on interest and payoff their loan faster. However, borrowers need to assess whether they can commit to a higher monthly payment amount.

Is it harder to qualify for a 15-year mortgage? Yes, it’ll be more challenging because of the higher monthly payments – lenders will want to be certain you can comfortably afford the loan.

Who Should Consider A 30-Year Mortgage?

A 30-year mortgage is a great option for borrowers with tighter budgets. Monthly payments are significantly lower than that of 15-year mortgages which means you’ll have more money remaining for other expenses and savings. However, 30 years of interest will add up to a much higher total cost over the life of the loan.

15 vs 30-Year Mortgage Example

The total difference in cost between a 15- and 30-year mortgage can be significant. For example, let’s compare a $300,000 loan with a 30-year mortgage and a 6.90% interest rate to a 15-year fixed-term mortgage with a 6.24% interest rate.

Comparison of a 30- and 15-year mortgage
30-Year Fixed Rate Mortgage 15-Year Fixed Rate Mortgage
Loan Amount $300,000 $300,000
Interest Rate 6.90% 6.24%
Monthly Payment $1,976 $2,571
Total Interest To Be Paid $411,288 $162,714
Total Mortgage Cost $711,288 $462,714

While the monthly payment for the 30-year mortgage is lower, you pay a higher interest rate over a longer duration which greatly increases your total mortgage cost. The 15-year mortgage is the more affordable option in the long run.

Aside from the loan term, there are many other factors to consider when calculating your monthly payment and total mortgage cost, including the downpayment, homeowners insurance, property taxes, and closing costs – which usually range from 3% to 6% of the loan amount.

Once a prospective homeowner explores their loan options, the next steps are getting pre-qualified and pre-approved. What’s the difference between a mortgage pre-qualification and pre-approval? A pre-qualification is the first step, giving you an estimate of how much you can borrow, while a pre-approval involves submitting any credit and financial details the lender requires for an official mortgage application.
