The expression is common in the USA. It is usually related to money, but it could be used to describe bringing to an end a romantic relationship or a variety of other things.

"We have dated for a year and she cannot decide if she wants to marry or not. I think I will cut my losses and go."

An expression with a similar meaning is "to quit while the quitting is good."

"I keep losing money in this restaurant. I am tired of working hard and not seeing any profits. I think I will quit while the quitting is good."
