Do you want to know how to calculate a mortgage? Do you know you can calculate your monthly payment by using a mortgage calculator or by doing it by hand?
Calculating your mortgage by hand is beneficial because you’ll learn how different factors work together to affect your monthly rate. These factors include the total amount you’re borrowing from a bank, the interest rate for the loan, and the amount of time you have to pay back your mortgage in full.
In this article, you will get to know how you can calculate a mortgage, how to calculate principal and monthly payments, the example of the monthly payments, and lots more.
How to Calculate Mortgage
Mortgages and mortgage lenders are often a necessary part of purchasing a home, but it can be difficult to understand what you’re paying for and what you can actually afford.
Let say you borrowed $265,000 on a 15-year mortgage at 4.32 percent. Start by dividing 0.0432 by 12 to find that the monthly rate equals 0.0036. Next, add 1 to 0.0036 to get 1.0036. Third, multiply 15 years by 12 payments per year to find that your loan consists of 180 monthly payments. Fourth, raise 1.0036 to the negative 180th power to get 0.5237. Fifth, subtract 0.5237 from 1 to get 0.4763. Sixth, divide 0.0036 by 0.4763 to get 0.00755826. Finally, multiply 0.00755826 by $265,000 to find your monthly payment will be $2,002.93.
How to calculate principal and monthly payment
To estimate your monthly mortgage payment, you can use a mortgage calculator. It will provide you with an estimate of your monthly principal and interest payment based on your interest rate, down payment, purchase price and other factors.
Gather these data points to calculate your monthly mortgage payment:
- Home price
- Down payment amount
- Interest rate
- Loan term
- Taxes, insurance and any HOA fees
Example of Monthly payment
M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1].
- M = Total monthly payment
- P = The total amount of your loan
- I = Your interest rate, as a monthly percentage
- N = The total amount of months in your timeline for paying off your mortgage
Plug those numbers into the payment formula:
{100,000 x (.06 / 12) x [1 + (.06 / 12)^12(30)]} / {[1 + (.06 / 12)^12(30)] – 1}
How much interest do you need to pay?
Your mortgage payments is important but you also need to know how much of it gets applied to interest each month. A portion of each monthly payment goes toward your interest cost, and the remainder pays down your loan balance. Note that you might also have taxes and insurance included in your monthly payment, but those are separate from your loan calculations.3
An amortization table can show you month by month exactly what happens with each payment. You can create amortization tables by hand, or use a free online calculator and spreadsheet to do the job for you. Take a look at how much total interest you pay over the life of your loan. With that information, you can decide whether you want to save money by:
-
Borrowing less (by choosing a less-expensive home or making a larger down payment)
- Paying extra each month
- Finding a lower interest rate
- Choosing a shorter-term loan (15 years instead of 30 years, for example) to speed up your debt repayment
Factors that influence the type of mortgage
