Should I pay off my credit card?

I have a quicksilverone credit card at capital one. I have a 500 dollar credit limit. Until September of 2016, I have a zero APR. I owe 317.41 dollars for my credit card and I have 434.64 dollars in my capital one checking account. I also have at least 600 dollars in other bank accounts. I don't get paid again until the 31st. Should I pay off my credit card now? Or should I wait? Please explain your choice. Any tips or ideas are welcome. Thanks
