I don't actually think you need as much as £100k to go private... if you have a girl, that is, and choose day school over boarding.
We are lucky enough to live in an area where there's an abundance of good private schools and most of the day schools for girls (e.g. one gets 20% admission to Oxbridge, loads to Bristol/Durham/St. Andrew's/King's/UCL...) costs around £12k per year.
I know plenty of working mums pay that for nursery fees alone - with a household income of about £80k. Of course, things would be tight here and there, but nursery would have "trained" you for that. Obviously, it is advisable to have more - but considering that these parents may have only been in their careers for 5-10 years, they will probably earn more as time passes by.
However, if you have a son, you are looking at around £15k+.
And boarding, obviously substantially more.
