You mean per year? Also I think you miss one zero in the 9th. Can You please also provide a source?

That is indeed per year in GBP. That is published by the UK Government directly: https://www.gov.uk/government/statistics/percentile-points-f...

I noticed that I used an older version, so the number have increased a little. The trend is the same though, with

50th: 23200

90th: 53100

95th: 75000

and taking off after that.
