How much money should I get paid to work in the house?

If this is the house you live in you should just be doing these things to help out free of cost. If it's your parents house you should certainly be doing this to help out, they already pay for the roof over your head, your food, and school needs. If your parents have agreed to pay you for chores around the house I would expect to only pay for things that aren't part of weekly cleaning. For example you could maybe offer to wash all the windows in the house, or paint a room, if you want to be paid for it. Things that are done as regular house keeping you should not be paid for.
