There is no hard limit per say, but the internal limit is based on your spending patterns. So say they start you at 5k, which you can check through your account online with them. You can put certain amounts in to figure out what your internal limit is. if you try spending more than that limit, you must call in to get them to approve.
If they see you run a lot of purchases through the card, they raise your internal limit so you don't have to call them to approve a large purchase.
So basically the internal limit is the maximimum amount you can charge at one time without having to call them to get them to approve more. Your spending habits influence this number
Anything. Navy Federal has the most generous credit lines by far.
I have a charge card for personal use and a revolver for business use. I highly recommend that you join navy federal credit union today... I have a card with them; 2 auto loans; an overdraft line of credit.. they are amazing to work with. If you love the idea of rewards do a PRG and use NFCU for revolver.
On a serious note I hear nothing but good things about them great advice great cards CLI the works
You should go for Navy Federal credit union. They do more to craft their products to your financial needs.And you will probably get a $15K limit with your scores.
