I do exactly the same as Catwalk W. There are things my 11 year old does and we call that "the price of living" in our house. Up until this past year, it was mostly just self-care and helping me out - like helping me get dinner, or helping me unload the dishwasher.
Now that she's older and more capable, I added on some things like unloading the entire dishwasher or doing laundry that isn't hers (like the towels).
She can "earn" money by doing things, basically, that I don't want to do (lol) like clean my bathroom (for $5 she has to clean tub, sides of tub, toilet - entire bowl and wipe outside as well as round base, sweep and mop floor, clean mirror, clean sink and counter, wash and rehang display towels, empty trash and wash the trash can). She can do that at least once a week. We have a 'community bathroom' that she can also clean once a week in the same manner also for $5.
She can sweep and mop the kitchen floor for $2 and she could do that every other day, if she wanted. She could vaccum the upstairs for $2, and she can do that every other day (4x a week).
So, her *earning potential* each week would be $26 if she did absolutely everything as often as she is allowed.
***** however, all homework, practice and *her* stuff has to be done before she can earn any money. So, she doesn't have time some weeks if she is studying extra for a test or she has extra homework or whatever. Realistically she probably *earns* $40/month.
Pretty much this is her ONLY money, unless she gets money for gifts. I set a budget for clothes. Once it's gone, she buys anything else she wants. If she wants to "upgrade" (ie, I set a budget of $100 for summer clothes. She wanted Abercrombie shorts..... that was 1/2 her budget. she had to pick if she wanted 1 pair of shorts and basically 1 swimsuit..... or shop at Target and get stuff on sale and more stuff.)
If we go to a movie - I pay for everyone's admission. She's not dating yet or really even doing much with friends just them without adults.... so we haven't had to cross that bridge yet.
