What does it mean when you have an available balance on your credit card?

You must make the minimum payment


You can charge more to your account


You must pay the available balance before you can charge more


Your balance has exceeded your credit limit|||It means you have additional credit on your card.|||Available balance is the difference between what you have charged and your limit. It's how much more can be charged on your account.|||I think it is the maximum amount of money you can spend using that credit card.


I am not 100% certain though :/
