The one thing that isn't brought up is the fact that the person who pays off his mortgage early will have a large sum of money every month that is available for investing.
Person 1 has a 30 year mortgage with an $800 payment
Person 2 has a 15 year mortgage with a $1000 payment
Person 1 puts that extra $200 into an investment that earns 8% a year. After 30 years he will have $298,071.89
Person 2 puts the entire $1000 into an 8% investment for the 15 years after he pays off the mortgage (same 30 total years as Person 1) and will end up with $346,038.22
Using that logic it is better to pay off the mortgage if you are disciplined enough to invest the money when the mortgage is over.
Also, this doesn't take into account the extra money Person 1 will save from the tax benefits of a mortgage. If you add that in the numbers may even out a little bit more.
I think your math is wrong, because every time I figure this out I come out with just the opposite. Apples to apples, here is what I figure.
You have 1000 a month. You have a 100k loan at 5.5% for 30 years. You can do 2 things. Pay 567.79 a month on the loan for 30 years and invest the remainder at 8% for 30 years. Doing this at the end of 30 years you'll have a house plus about $634,549.29.
That is your person 1.
Person 2 pays 1000k a month on the loan, and has it paid off 11.25 years. So for 18.75 years he can invest 1000k at 8%. At the end of 30 years he'll have the house and about $537,143.57. As you can see, paying off the house is the worse of the two ways.
I struggle with this though every day. I am in a position that I am buying a house in July and could pay the thing off in 5 years. But as you can see from the numbers above, on paper it doesn't make sense to do it if I could invest that money and get 10 or 12% return over the next 20 years. (I'm 24, so I have plently of time to let the money sit.)
This is all of course best case scenerio. Figuring out my place (it's about 230k loan) an investment could pay my monthly mortgage payments in about 5-7 years if I get a good return.
usually a 15yr mortgage is .5% less than a 30yr mortgage.
How do the #'s come out after adjusting for that fact?
