Are there chinese idioms similar to 'It takes money to make money'?

This seems like the type of question that would be good for the StraightDope. It’s not something you can find with a quick google search. At least, I didn’t see anything.

Is there any type of old Chinese sayings or idioms equivalent to ‘It takes money to make money’?

If you could also type the chinese characters that would be much appreciated.
