If you are using a hand-held financial calculator (not an online version), you will need to be familiar with the different buttons used in a calculation.
Most financial calculators will have buttons labelled, "N, I/YR, PV, PMT, FV".
N stands for the number of payments (360 for a 30-year mortgage).
I/YR stands for Interest Rate.
PV stands for Present Value (the amount financed).
PMT stands for Payment.
FV stands for Future Value. This is usually set to 0 for mortgage payment calculation purposes.
Mortgage calculators are great tools for calculating basic mortgage payments to give you a simple idea of roughly how much of a mortgage you might be able to afford. However, there are a lot of other factors that need to be considered, that many times only a mortgage professional can correctly account for. Some of the other items that need to be considered are, how much are the property taxes on the home you are looking to buy. This needs to be considered into your monthly mortgage payment. Also, how much is the homeowners insurance going to be. This is another item that is commonly included in your mortgage payment. One other item is will you have to pay private mortgage insurance, also known as PMI, and if so how much. Your credit, credit score, and your loan to value on your loan will play a significant role in determining how much the private mortgage insurance is going to cost you. Therefore, there are many different factors that will change the payment from the simple mortgage calculator that you may use, and the best way to find out how much of a home you can comfortably afford is to seek the assistance of a mortgage professional.
A mortgage calculator will only tell you very basic information about your loan. There are other things that play into what the loan will actually cost you. A mortgage professional can help you use that calculator and get an accurate monthly payment.
The calculator will help you get the basic information. However how to correctly interpret what that information means to you and your goals often takes the help of a mortgage professional.
