My 15 year old has 80 per month no strings attached, but she buys her own clothes except sports kit (no school uniform).
13 year old was offered the same arrangement but wants me to keep buying his clothes so he still only gets pocket money - 6 per week. Unconnected to chores, no strings.
The 3 kids (10, 13 15) do the dishwasher alternately, they police it themselves, there are no arguments with us and they have a list stuck to the dishwasher.
They each put their own laundry away - I don't police the older two, only remind the littlest, but basically if they don't do it they have to keep going to their basket in the laundry room for clean clothes - not my problem.
Their rooms are up to them, nothing to do with me, I don't live in them. This is possible because we have a strict no food and drink except water upstairs rule which applies to all of us - DH and I too - because DH and I stick to it there's not much room for argument.
The older two cook our evening meal quite often, at least once per week - sometimes the middle and youngest cook together. Whoever cooks chooses what we eat. It's also unconnected to money. They usually do it voluntarily or if I'm working late. Sometimes we ask one of the older ones to cook but in that case it's fine to bung freezer pizza / fish fingers or something in if they don't want to cook.
Eldest often does her own laundry but if she sticks it in the family laundry I do it - she prefers to have her s under her control. Unconnected to money.
They can earn money if they want by asking me if I want anything doing and how much they'll geet for it. I can always find a task if they want to earn money. Generally only the eldest does, but sometimes she has phases of doing lots of extra chores for money (cleaning out the garage, sorting outgrown clothes, family laundry, cleaning the kitchen) but also months when she does nothing - this is fine.
