if that

As a maximum amount; at most. Used after some small amount of something to indicate that it is the most that should be expected. I love making videos for ViewTube, but they certainly don't pay the bills. I probably earn about $30 a week, if that. I've only got about a week's worth of work left for you, if that, so you might want to start looking for something new. You know I never have cash on me. I might have $4, if that!
