Charging rent for 19 year old

[Paddingtonmum]

I need a bit of advice. My little brother has had to move in with me and my partner because of issues at home. He's almost 20, works full time in a shop.

Everything has gone up on cost since him being here and initially we said we'd charge him £100 a month just to cover his food and that, but I don't think £100 a month is even anywhere near covering that. I don't want to make any money off of him, but I can't afford to be paying for him too when he works full time and I have my own children to pay for.

What do other people charge adult children to live in their house? I don't want him to be paying anything more than what he actually costs e.g. food and increase in bills due to him being here x

30% of income on housing, light & heat, food, washing & toiletries (?) is an absolute bargain.
Never again in his life will he be able to live so cheaply.

If all this was only costing him 30% he'd still have 70% left for personal costs - that's £700.
How much does your family have for personal spends OP?

Seriously £100 a month leaving him £900 of disposable income.

You need to sit him down and explain food bills have gone up, fuel bills, water etc and have a discussion. I’d say £250 was more than reasonable.

If you find it hard to work out the cost of what he eats I am bemused you think randoms who do not know you can.

If he has a take home pay of 1k then & charging him £100 then not only are you being foolish towards your own family but to him as well. How is your brother going to manage if he has to get is own place? Living costs money & not cheep. He needs to learn the true cost & bugeting and running a home. I had my own place at 16. It was hard as I didn't know the first thing about anything realy but I'm still in the same flat & own it now. I made a tremendous amount of Financial mistakes because I didn't know or have much experience of living costs. You & your brother have an excellent chance to avoid what I when through & it will also help your kids when they grow up.
