The Bible has a great verse in Proverbs, which is just that, a book full of wise sayings and principles.Actually, it has lots of good advice in Proverbs....it's one of the books I just love to read because it's so helpful!
22:7 "The borrower becomes slave to the lender."
3:28 "Don't tell your neighbor to come back tomorrow to get it, when you have it with you now." *
*these are paraphrases.
So the Bible seems to say that it's not great to be in debt, because as long as you owe someone money they can do bad things to you, like take your house or car. It also says that if you've got the money now, pay it!
And this works out practically too. In economics class we had to construct a table that showed how long it took to pay things off based on how much you paid. I made an excel spreadsheet that has a bug or two in it, so it's not always right, but it does the same thing as the linked website, and shows you an amortization table for it, so you can see how you are saving money.
If you pay off more principle in the beginning, they can't charge you interested on it in the next payment. So you pay less interest every single payment. What's interesting is an amortization chart that shows how much of your monthly payment went to interest and how much towards principle. In the beginning, very little goes to principle. As it's not being paid off much, you still get charged alot for interest. About halfway through a loan, you have paid off what you owed, the rest is just cushioning
It's why a 500k loan costs you 750k. Oppurtunity cost.
So yes, pay off as much as you can! My dad paid off a 30 year note in 7 years by working extra calls and paying it off maniacly....about ayear into it he realized how much he could save and devoted himself to paying it off early. Now his "monthly payments" go into retirement funds--when you are done paying off the house, don't take the money and go bonkers withit! You are used to living without it, so put it into savings, stocks or bonds or whatever you want really, anything helps. Not only is this money for your retirement, but the less you live on per year before you retire, the leess you will need when you retire per year to maintain a similar lifestyle.
Money always seems to have a snowball effect.
