broadly 20% of income but self employed so it definitely varies, but a tiny mortgage and we have savings to cover fees during lean years, we aren't flash with our money anyway, oldish car etc.
no question our indy did better during lockdown than the local state schools, hands down. Full weeks online timetable, balanced between academic, creative and active. The school announced covid planning in January and was prepared to switch to online after February half term if they'd had to. The local state by all accounts did very little, many parents grumbling (although not loudly because they don't want blowback on their DC when they return).
We moved our DCs to indy because the local 'outstanding' state school was toxic, cliquey, incredibly badly managed I could write a book. Ultimately DC ceased to learn there so we pulled her out. The local state high schools are not much better, one in particular talks the talk and there are definitely more flashy cars at parents evening than at our indy, but when friends kids are being tutored in core subjects from year 9 or removed because of bullying and we hear reports of drug taking and blow jobs in the toilets, its a no from us. I don't care how good their exam results are.
Our indy is not academically selective and won't worry the league tables results wise but they try to get the best out of each individual and OMG they find what those kids are good at individually so they take flight.
I don't give a fuck about social connections for DC in later life either, if you use indy school for that fair play to you but its a pretty shallow reason for anyone to spend so much money IMO. Smaller class size definitely better for our DC, it only takes a couple of disruptors to trash a year group for mine and they can't learn, in indy where expectations of behaviour are much higher, much better discipline this doesn't happen.
From chatting to family and friends (some are tutors), tutoring is rife in the SE schools, state and indy (I won't name names but I got a shock). But its the land of the high achieving social climbing types so 🤷♀️. up here not so much.
Since ditching state for indy I have happy DC, its worth every penny.
