OK Gorgon, here's Dr Hamsta'a Financial Breakdown in Credit Cards.....
1) Credit cards are GOOD, as long as you use them and they don't use you! You can defer payment for up to 55 days on stuff which means the $$ stay in your bank account for longer. With most accounts in NZ that means less bank fees and a happier bank manager. Transaction fees are charged to the retailer, not to you. You can easily buy stuff from overseas retailers without messy and expensive cash tranfers. They can help you get a good credit rating so financial institutions smile at you when you go asking for loans or mortgages. They also work really well with revolving-credit mortgages, but that's another story.... In this part of the world they often also have incentive schemes to earn you rewards like air points, etc.
2) Credit cards are DANGEROUS if you don't use them carefully. Most cards start clocking up interest at around 17-18% if you don't pay you account in full. When you consider that most mortgage rates are at about 7% at the moment, that's sheer highway robbery! And the worst part is that as soon as that happens you get NO MORE FREE CREDIT. As soon as you buy anything more it starts accumulating interest FROM DAY ONE, no 55 day stand-down. This is where A LOT of people get themselves into deep financial SCHTUK. In the same way as a credit card can give you a good credit rating, it can also completely ruin it if you aren't careful.
My Basic Rules are:
1) NEVER pay for anything on your card that you don't have the money in the bank to pay for. This helps stop you from spending beyond your means.
2) ALWAYS pay your account IN FULL on the day the balance is due. That way you avoid paying interest.
3) If you are constantly paying interest on your card you are being ripped off! Cut up the card, pay off the remaining balance asap, and close you credit card account! Learn to live more within your means, and maybe later when you're more financially secure you can think about a card again.
Credit cards can be really useful. I use mine almost exclusively for day-to-day stuff like groceries, gas, bills, etc. It clocks up the air points and I avoid the transaction fees each time I make a purchase, plus my bank manager loves me! BUT I ALWAYS PAY THE FULL AMOUNT OWING ON THE DUE DATE!
Remember, money paid to the credit card company in interest is less money to spend on headphones and CDs!
Have fun, but hey, "Let's be careful out there!"
