WHen i apply my wife to US from Sweden, the sponsorship amount is your sponsor need to earn 17,500 or above in US.
They have a formula to calculate the sponsorship you need, i would say yopur sponsor need to earn more than 17,500 USD to be able to sponsor your application, more if you have dependent children.

Notice that bank account alone cannot be used as a Sponsorship proof.
