How to say this ?
Hi dear native speakers

Consider the following context:

You friend wants to pay in cash for sth, but he finds out that he doesn't have enough money. How would you informally tell him " how much more money do you need?"

Thanks

Answer

You could say 'how much more do you need?' - that's fine, or 'How much are you short?'
He could say 'I'm short 10 bucks' for example.
