How to profit off your credit card

I know in the near future, I am going to have a few large expenses. One, I may be moving, and two, I want to get a nice sized LCD for the new place. While I have the money to spent, there are also really nice short-term rates out there in the form of high-yield CDs that many banks are offering.

How do I take advantage of this?

Well, consider that the total expenditures I expect to make are about $5000 (shocking that this is the same amount as the minimum at most banks for said high-yield CD). Instead of spending it, I went out and got a high limit credit card with a 0% APR offer for 6 months.

That way, I can charge the expenses to the credit card, paying the minimum balance to avoid any fees, and since there is no interest involved, by the time I have to pay, the balance would be $5000 - 5 x minimum payments. Considering a minimum payment of 2%, that's about $100 a month. So I would have to pay a lump sum of $4500 by the sixth month.

At the same time as the purchase, I put the $5000 in cash into a 6-month CD at about 5.30% APR. That's about $22 a month in interest, or by the end of 6-months, about $134!

And there you go, if you plan it correctly, you can eat your cake and keep it too!
