How to Figure a Mortgage Payment – A Quick and Easy Way to Calculate Payments in Your Head

There are several ways to calculate monthly mortgage PITI payments. PITI stands for Principal, Interest, Taxes (property taxes) and Insurance (home owner’s insurance).

o You could use a long, complex formula like: P = L[c(1 %2B c)n]/[(1 %2B c)n – 1] Does that sound fun to you? Me neither.

o You can use an on-line calculator. They are all different, though. Some are good, some are not. But if you are out house shopping and do not have internet access – not an option.

o You can even use a special, hand-held realtor calculator that will prompt you step by step to enter all the variables like: home price, down payment amount, interest rate, length of the loan, etc., then it will calculate the monthly mortgage PITI payment. However, these calculators are expensive, and unless you are a realtor, you will no longer need it once you find your home or refinance – not a cost-effective option.

You need a quick and easy way to figure your payment in your head, or maybe with the calculator in your cell phone.

Believe it or not, there is a way. It is very straightforward and will give you a ballpark estimate of your PITI payment.

Are you ready for this? It is super simple – just a one step multiplication problem. OK. Here it is. To estimate your monthly mortgage PITI payment multiply the amount of your loan by .008 . That’s it…seriously! (As long as mortgage interest rates don’t change drastically from what is available in Jan 09)

o If you are going to buy a $200,000 house, and you can pay $10,000 down, your loan amount will be about $190,000.

o The math looks like this: $190,000 x .008.

o Plug those numbers into your calculator.

o Your monthly mortgage PITI payment will be about $1520 per month.

Be advised, this figure is only an estimate – a simple way to get an estimate when you are not able to get to a computer. If you are in contact with a realtor or loan officer, they can give you a much more accurate idea of your monthly mortgage PITI payment.
