I’m a single parent, DD18 is studying (at home) and working part time. She gets approx £750 a month including her wages and an allowance from her dad. She has a car to run, a phone contract and a gym membership but no other outgoings.
She’s good at budgeting and keen to pay her way but I’ve no idea what is fair to charge her. I could really do with the extra and think it’s a good life lesson for her but I want to be reasonable. What do other people do?
