You pay off the entire balance 1 month later by the due date but if you REALLY can't, you try to consolidate it and refinance it with consumer loans at much much cheaper interest rate. You can sometimes do a balance transfer to another credit card that's having a promotion for 0% interest on balance transfers (MBNA has this ALL the time. They basically earn a balance transfer fee) or another payment arrangement offered by the card issuer. The bottom line is you do NOT pay the huge 19%, 20% interest rate that's on the card itself. This is what cripples your finance and you hear those stories of people who have to take longer time to pay off their credit card debt than paying off their mortgage. It's because they didn't manage their finances properly. Those double-digit interest rates is ok if your balance is small and you forgot to pay for just 1 month then it's no problem, you pay it off right away the next month. With the interest at 20%, on a balance of $3.5K for 1 month, the interest is just $0.2 X 3500 X 1/12 is about $58.33. It's very manageable. But if you have accumulated a huge balance of let's say $35K let's say, even for 1 month, 20% interest rate will incur you an interest amount of $583, and that's just 1 month. Imagine if you have been in arrears of 2, 3 months then that interest amount quickly becomes almost $2K and that's when the credit card debt starts to get out of control.
You cannot let things get out of control. Just like when you incur losses in your trading, you need to do a stop-loss. It's the same thing here. You need to stop-loss this credit card debt that's growing at 20% interest daily. How do you stop-loss a credit card debt? You either pay the entire balance off as quickly as you can, do NOT pay just the minimum amount and (not or) you refinance it with loans with cheaper interest rates just like how you refinance your mortgage. People all know how to refinance their mortgage by shopping for a cheaper mortgage rate but they do not know how to refinance their credit card debt. They think the amount is small so they can just pay it off slowly. No a credit card debt might be a small amount but it's at 10 times the interest rate so it's growing 10 times faster than the mortgage. The mortgage might be in a much larger amount but the interest rate is much much lower so at the end it amounts to the same thing. When your credit card amount outstanding is 5 digit for several months, at 20% interest, it's really become a second mortgage if you just pay the minimum amount required. The good thing is it's an open mortgage that you can refinance at any time. Just like for a mortgage, you shop around for cheaper consumer loans with lower interest rate and you use it pay off the ENTIRE balance of the credit card debt that's incurring the 20% interest rate and then you pay off the consumer loan that's at a cheaper hopefully much cheaper interest rate that should be much more manageable until it's paid off and then you can splurge again on credit card by replacing another 4 discs of your Mercedes or better buy another Mercedes on your credit card.
There is no caveat. You just manage it. Credit card is absolutely FANTASTIC! But just like anything that's fantastic, you have to manage it.
