@countdowntofriday - you asked what people do to make their DC financially literate
Here's what we do (although they are both still in primary school so amounts of pocket money will change as they get older.)
Both DC get £5 a week pocket money. They take this to the bank and pay it in (although this was pre covid, now we just direct debit it in) . Any time we're in town and they ask for toys/sweets/Smiggle goodies we tell them they can have it, but they need to go to the bank and withdraw the cash. This has worked to stop most nagging for things as they like watching their savings grow. Occasionally they save up for something big (massive Lego, etc). Birthday and Christmas money goes into this account too. We get paper statements once a month where we go through and check deposits and withdrawals (do they remember what they spent their money on?) And they love seeing how they have earnt interest (although it's usually around 50p a month).
Once a month they choose a charity to give £5 to (we don't take this out of pocket money)
Our general idea is that they use some of the money to save, some to spend and some to give to those less fortunate than themselves. Sometimes it's used to sponsor friends, for school charity appeals (like red nose Day) or sometimes they will give it to a homeless person, or a children's charity in Africa. Our thinking is that our DC actually live a very privileged life and we want them to be aware that not everyone in the world has access to all the things they have. I think charitable giving is a good habit to get into.
As they get older (into teenage years) we plan to give then an allowance for all the things they want/need. So they will have to budget for clothes, makeup, Starbucks with friends, cinema trips etc. If they blow all their money in the first week then they'll have to wait till next month to get more.
As a family we don't hide talking about money/family finances. So for this summer holiday we said we had a £1000 budget - and asked them what they wanted to do with it? We could get a few days away in a cottage (cost x amount), or we could go on several camping trips (cheaper) and have money left over for zoo membership and lots of trips to the local beach with ice creams etc. So we involve them in planning how we spend the cash.
My parents never taught me about budgeting and it led to quite a shock once I had regular rent and bills to pay. I don't want my DC to be scared of going into banks or embarrassed to talk about money so we are trying to ensure they grow up with some awareness of it.
I'm not sure if we are doing it right, or doing it all wrong but my 10 year old is more financially literate than I was at 20 (although that's not saying much)
