I'd like my 14 yo DD to learn to manage cash and she is quite keen to do it. We would cover all basics but she would use allowance to cover any extras like nail varnish, Starbucks trips, geezer, extra clothes, extra treats for guinea pigs, cinema tickets etc etc etc. But I have no idea what is reasonable for a monthly allowance ... And would appreciate some help. FWIW we live near London.
I have opened a bank account (with a debit card) for my two DD's (12 and 13) and put in a weekly deposit of £6 and £6.50 (half their age). Every birthday it goes up 50p a week. I buy their main clothes and they buy anything I don't consider a 'must have'. 12 yr old spends the money like its going out of fashion on this and that from ebay/itunes. 13 yr old saves and begrudges spending any money, but she knows she has to when going out with friends.
DD2 who is 14 gets £30 a month. I do also pay for her phone top ups, but I won't pay more than £10 a month and she has to keep enough credit on there that she can contact us. If she uses it all by texting friends, she buys the next top up herself. Actually she is very careful with her phone use and it's about 3 months since I bought her the last one - mainly thanks to Tesco triple credit!
She is expected to do chores as and when required for that. Not too much, but hoovering now and then, wiping up when I need the help, feeding and cleaning out her gerbils and cat, and putting her clothes away (often on the bedroom floor unless I watch )
I buy a winter coat, sensible shoes, underwear and socks and pay for her dance and singing lessons and transport to these. She pays for casual clothes, her not inexpensive gaming habits, and little bits of socialising.
I have recently put it up from £25 to £30 as she has gone into Year 10 and I did the same for DD1 - but made it clear that chores are now expected when I need them. For DD1 I stopped at the end of Y11 and I will do the same with DD2. It didn't take DD1 long to find a part time job once the allowance stopped!
