10k is 10 per cent of their budget. If it's only travelling and going out, it seems a lot if the goal is to save.think 80-100 a week is reasonable, the odd cup of coffee or drink with friends is essential IMO. You’re young and should be able to have holidays and nights out.
Our current budget for holidays as a family of 4 (3 adults) is 10 to 12 k a year and last year I was away for 8 weeks on that budget (during school holidays with 4 trips abroad). I could probably add 2 k for going out.
