Mathematical Mortgage Formula

The biggest question that prospective home buyers have is how to calculate a mortgage or the mathematical mortgage formula needed to arrive at an estimate. The biggest reason for this is to have a rough idea of how much they can afford to borrow and their possible monthly payments.

A very simple mathematical mortgage formula will require you to determine first what the current prevailing average mortgage rate is. What you can do is simply gather the lenders different rates, add all of them and the sum will be divided by the number of lenders rates. For instance, you inquired from three lenders and their rates are 3, 4, 5, add all these numbers which will be 12, then you divide it by three and comes to 4 percent. That means your average rate will be four percent. You can use your ordinary digital calculator at home especially when dealing with decimal points.

Then now you have to apply it the amount of property you are looking to purchase. For example you planning to purchase a 500,000 dollar house, this is how it will look like;

500,000 x 4% = 20,000, then you divide 20,000 by 12 months which would equal to 1,666.67 which will be your monthly payments. This is if you are doing it manually, but the best thing for you to do is to go online and search amongst the many mortgage calculators that can easily provide you with the answers.  

A simple mathematical mortgage formula or calculation of your possible monthly payments cannot be relied upon as the sole interpreter of you much you can afford and or borrow for a mortgage. It can however help you get some very basic information on the possible figures you may be looking at. But far from the real mortgage amount for mortgage loan that you will be signing. The reason for this is the different home taxes and insurance from each state. There are no uniform state taxes and home insurances across the board which make it more difficult to just give a number and start calculating what you mortgage payments will be.

If you really want to go deeper into the mathematical mortgage formula, it will not be as easy as you may think. It is actually a complex mathematical formula that it is better interpret by a mathematician. So your best bet to calculate a mortgage is through a mortgage calculator which is readily available online instead of manually doing a mathematical mortgage formula yourself.
