When my child turned 7, I started giving him pocket money, £2 a week. £1 to put in his piggy bank to spend when he wanted, and 2 x 50p to go into 2 savings pots, one to open when he was 8, and one to keep until he is 16. His piggy bank already had about £30 in it. I let him spend it all on Minecraft add-ons, as long as he brought me the money and told me how much change he needed, I paid for them with my card.
It took him about 3 months to run out of spending money. Then I explained he could either wait and save up his pocket money for what he wanted or do some work to earn it. The first time he chose to do some work, at other times he’s decided it doesn’t want it that much. When he turned 8 he was excited to open his savings pot, count up his money and go buy something he wanted. We started a new pot he’ll open when he’s 9, and his pocket money has gone up to £3 with the same split.
I’m hoping he’ll learn the value of money by the time he’s 18 - he has a cash JISA , s&s JISA and Premium Bonds, I’m expecting him to have around £40k at 18. He also has a JSIPP, I’m hoping it will be worth around £2m when he reaches 57, but of course I can’t predict share values! In between 18 and 57 I expect he will inherit something, so he basically has three chances in life! If, like me, he gets it wrong twice, I’ll be glad I set up the SIPP for him.
