"Statement balance" refers to the amount of money you owe to a credit card company at the end of a billing cycle. It includes all the purchases and payments made during that period. Full definition
I have paid statement balance in full today, so it's early than the due date. (money.stackexchange.com)
Having your account number and last statement balance on hand will help, too. (dime.com)
For most credit cards, if you always pay off your entire statement balance by the due date, you do not incur interest for purchases. (creditdonkey.com)
