How to Use This 15-Year Fixed Rate Mortgage Calculator
To use our calculator, complete the steps listed below:
- Enter the total amount of the mortgage you want. You can do this either by typing in the dollar amount or using the sliding scale below the dollar amount.
- Add the interest rate you’re being offered. This will typically be expressed as an APR, or Annual Percentage Rate. Our calculator will break down exactly how much money, in dollars, this amount comes to over the duration of the mortgage.
- Enter the number of months you plan to spend paying off the mortgage. This can be the number of months stated in your contract (for a 15-year mortgage, that would be 180), or a shorter period of time if you’re planning to pay off your mortgage faster.
- Type in any additional principal. This is any money added to the starting amount of your mortgage. In most situations, this number will be $0.
You will be able to see your results change in real time as you adjust each of these numbers.
How to Understand Your Results
There are three ways to look at your results: a simple bar graph chart, a detailed table, and a full amortization schedule.
The chart is a visual representation of your mortgage decreasing with each payment. In the browser, you can hover over the bar for any month to see the specific balance owed at that time.
Below the chart you’ll find a table detailing the following information:
- Mortgage Amount. This is the exact dollar amount you are receiving for the mortgage.
- Interest Rate. The interest rate being offered on the mortgage you’re looking at, usually represented as an APR (Annual Percentage Rate).
- Number of Months to Pay Off. The exact number of months you expect to spend paying off your mortgage; this can be the maximum number of months you have allowed, or a shorter period of time if you’re willing to make higher monthly payments.
- Additional Principal. In some instances, an additional principal may be added to the total amount of your mortgage. This may or may not come with an increased amount of time to pay the mortgage.
- Monthly Payment. The dollar amount you’ll need to pay each month in order to pay off your mortgage within the desired amount of time.
- Total Interest Paid. The precise amount of money you can expect to spend on interest throughout the duration of your mortgage.
Finally, the amortization schedule breaks down how much of each month’s payment goes toward paying off the principal of the mortgage, and how much goes toward interest. It also shows exactly how much your mortgage balance decreases each month.
