People that understand interest, EARN interest.
People that do not understand interest, PAY interest.
Yup! Last year I actually did earn more in interest than I paid.
The reason I pride myself on this so much is because years back I had buried myself in debt (started a business on CCs - bad idea). It took about 7 years to pay it all off. By the time all was said and done I had paid an enormous amount of interest... even with 100% on-time payments. Even though I was deep in debt, I did not allow it to hurt my credit.
After going through that I decided I would only used credit if it was to my advantage. As an example... when I bought my last car I decided to finance more of the price because my car loan interest rate is lower than my savings account interest rate. Basically I am making money off of financing my car.
My bank, the same day, cancelled my line of credit and lowered the limit on my ATM card. Imagine my embarrassment when I went to buy a new hard drive for my computer - there was plenty of money in the bank - and the transaction was declined. The bank had lowered my debit card limit from $1,000 to $300. So if I needed more than $300 at any time I had to physically walk into my home branch of the bank to get it.
Time to drop their ass and get a new bank! It pisses me off the way banks are more than eager to screw someone over by trapping them in debit with high interest payments... but the moment you turn the game around on them they get pissed.
