> taking a 5% loan for the 6 weeks? You need to actually invest the money versus paying the credit card to earn interest. And I do. I don't have any actual money. It's all invested. I look for ways to borrow money at a lower rate and invest it at a higher rate. > Realistically a person will take out loans for like 4-5 transactions in their life where this actually matters. Every time you buy something with a credit card, you take out a 0% loan for 6 weeks. If you pay attention to what a bank does, if the bank hands you a check for borrowed money, they start charging you interest immediately. If you pay off the loan by handing them a check, they charge you interest until the check clears. I.e. the bank works the float both ways. The pennies add up. If you're not aware of this for a large transaction, the other party surely is and is taking advantage of you. A few years ago, it was commonplace for late night TV to run seminars that I call "Make Money By Real Estate Scamming". I decided to watch one and see how it went. The presenter presented a series of transactions that ended up netting the buyer $15,000. It was complicated, so I set about figuring just how the $15,000 from nothing came about. It turns out it hinged on giving the sucker a bond that paid $X upon maturity in lieu of paying $X today. The $15,000 was the interest on the time to maturity. The complications were all about hiding this.

For example, I'll get flyers in the mail offering mortgages for an absurdly low teaser interest rate for the first year, and after the first year the interest rate goes above market. I carefully read the contract. If there's no prepayment penalty, I'll get the loan. A year later, I refinance and pay off the first mortgager. I asked my loan officer "why do they do these contracts?" He laughed and replied they were playing the odds - the vast majority of people are too lazy to refinance, or didn't read the contract. Once I bought a new car, and they offered 0% financing after we agreed on a price. I asked, why would they offer 0% financing? The dealer said the terms of the contract were if you are late on a payment, you get hammered with interest. I said sure, I'll take the loan, and set up an automatic payment plan. This is all basic stuff. The credit card thing is mostly just for practice.
