多少钱？

You can use it alone by pointing at an object. Just say 多少钱？ while looking at that shiny teapot. You can also put the object first. For example, 这个多少钱？ means 'How much is this one?' It is incredibly flexible. You don't need complex grammar to make it work. Just drop it at the end of your sentence. It is the linguistic equivalent of a Swiss Army knife.

Use it whenever money is about to change hands. Use it at the grocery store for apples. Use it at a restaurant when the bill hasn't arrived. It is perfect for taxi rides too. If you are texting a seller on an app, it is the standard opening. It is practical, clear, and gets straight to the point. No one will be confused by this phrase.

Don't use it if you are asking about someone's salary. That is considered quite nosy and rude in many contexts. Also, avoid using it for 'how many' when not referring to money. For people or objects, use 几个 or 多少 without the 钱. If you are at a very formal charity auction, there might be more elegant ways to ask. But for 99% of life, it is safe. Just don't ask your date 多少钱 after they buy you dinner!

In China, prices aren't always set in stone. Asking 多少钱 is often the opening bell for a friendly negotiation. In local markets, the first price given is rarely the final price. It is a social dance. Money is discussed much more openly in China than in some Western cultures. Don't be shocked if a new acquaintance asks how much your shoes cost. It is often a way to give a compliment on your good taste.

You might hear 这个怎么卖？ which means 'How is this sold?' This is very common in produce markets. Another one is 一共多少？ for 'How much in total?' If you want to sound like a local pro, try 多少？ with a quick downward tone. It shows you mean business. For very cheap items, some might say 几块钱？ which means 'How many bucks?'
