When considering a mortgage, one of the most important decisions you'll make is choosing between a 15-year and 30-year loan term. This calculator helps you compare the two options by showing monthly payments, total interest paid, and total cost of the loan over time.
What is 15 v 30 Year?
The term "15 v 30 Year" refers to the comparison between a 15-year mortgage and a 30-year mortgage. Both options have their advantages and disadvantages, and the best choice depends on your financial situation, goals, and risk tolerance.
Mortgage terms are typically offered by lenders and can vary based on interest rates, down payments, and credit scores. Always check with a mortgage professional for personalized advice.

- Faster ownership of your home
Key Features of 30-Year Mortgages

How to Use This Calculator
Using this calculator is simple. Just enter the loan amount, interest rate, and select the loan term (15 or 30 years). The calculator will then display the monthly payment, total interest paid, and total cost of the loan.
Formula Used
The monthly payment is calculated using the standard mortgage formula:
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]
Where:
- M = Monthly payment
- P = Principal loan amount
- i = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years multiplied by 12)
Example Calculation
Let's say you're considering a $200,000 mortgage with a 4% annual interest rate. Here's how the calculations would work:
| Loan Term | Monthly Payment | Total Interest Paid | Total Cost |
|---|---|---|---|
| 15 Years | $1,420.46 | $126,055.20 | $326,055.20 |
| 30 Years | $995.74 | $186,322.80 | $386,322.80 |
In this example, the 15-year mortgage has a higher monthly payment but results in lower total interest paid and total cost over the life of the loan.
Key Differences
There are several key differences between 15-year and 30-year mortgages that you should consider:
Interest Rates
15-year mortgages typically have higher interest rates than 30-year mortgages. This is because they are considered higher risk by lenders.
Monthly Payments
15-year mortgages have higher monthly payments than 30-year mortgages because the loan is repaid more quickly.
Total Interest Paid
The total interest paid over the life of the loan can be lower with a 15-year mortgage if you can afford the higher payments. However, if you can't afford the higher payments, the total interest paid will be higher.
Total Cost
The total cost of the loan (principal plus interest) is typically lower with a 15-year mortgage if you can afford the higher payments.
Ownership Timeline
With a 15-year mortgage, you'll own your home free and clear in 15 years, whereas with a 30-year mortgage, it will take 30 years.
Comparison Table
Here's a comparison table showing the differences between 15-year and 30-year mortgages:
| Feature | 15-Year Mortgage | 30-Year Mortgage |

| Loan Term | 15 years | 30 years |
| Interest Rate | Higher | Lower |
| Monthly Payment | Higher | Lower |
| Total Interest Paid | Lower (if payments are affordable) | Higher (if payments are unaffordable) |
| Total Cost | Lower (if payments are affordable) | Higher (if payments are unaffordable) |
| Ownership Timeline | 15 years | 30 years |
FAQ
Which mortgage term is better, 15-year or 30-year?
The better mortgage term depends on your financial situation. If you can afford the higher monthly payments, a 15-year mortgage may be better because it results in lower total interest paid and total cost. If you can't afford the higher payments, a 30-year mortgage may be better because it results in lower monthly payments and potentially lower total interest paid over time.
Can I refinance a 15-year mortgage to a 30-year mortgage?
Yes, you can refinance a 15-year mortgage to a 30-year mortgage. This can be a good option if you want to lower your monthly payments or take advantage of lower interest rates.
Are there any penalties for paying off a 15-year mortgage early?
Some lenders may charge prepayment penalties for paying off a 15-year mortgage early. It's important to check with your lender to understand any prepayment penalties that may apply.
Can I get a 15-year mortgage with a lower interest rate than a 30-year mortgage?
In most cases, no. 15-year mortgages typically have higher interest rates than 30-year mortgages because they are considered higher risk by lenders. However, there may be exceptions depending on your credit score and financial situation.
