Thanks for letting me know about the annual fee, I didn't even know credit cards had them. Shows that there is a lot for me to learn huh? :)
So it seems the link you sent showed the journey card to not have an annual fee, but the Purchase Rate is (20.24% variable APR). What exactly does that mean?
APR is the annual percentage rate. It tells you the amount of interest you will be charged in a year. So, if you have $100 on the card, after a year you will have $20.24 in interest. Of course, your balance will go up when you make purchases and go down when you make payments, so what it really means is that you get charged 1/12 of that rate every month on whatever balance you have that month (actually a bit more complicated than that, but that's the gist). So, if you buy $100 of items in the first month, at the end of the month you will get charged 1.68% interest ($1.68). Then you make a $10 payment, but buy $25 more in stuff (net $116.68 balance), so the next month you get charged 1.68% interest on $116.68 ($1.96) and your new balance is 118.64.
The "variable" part means that the bank that you have the credit card with varies your APR based on a base rate + modifier. The 'base rate' is the rate the bank is getting charged to borrow the money they are lending to you (yeah, they do that) + the rate they are charging you. The rate they get charged is called the "prime rate" which is what you hear about on the news when they talk about The Federal Reserve Bank "The Fed" setting interest rates. The Fed changes the prime rate as often as every three months.
IF you pay off your card
every single month you can avoid getting charged _any_ interest at all while still building your credit score. So two rules to build credit:
* Buy everything you can with your credit card,
but only if you actually have that money in the bank!
* Pay off your balance every single month.
In other words, use the credit card as a convenience tool, not to actually borrow money. This will build your credit and keep you from sinking into a debt hole.
Only actually borrow money with a credit card if it's an
emergency situation.
