It's annual Bad Maths Day!
Starting with Patreon, which is the one we can be most accurate with (and I acknowledge that it's not accurate enough!):
Today, she has 988 patrons. At the lowest rate of £3 per month, that's £2,964 a month, £35,568 a year. At the highest rate of £8.50 per month, that's £8,398 a month or £100,776 a year. I know the real rate is somewhere in between and also Patreon will take a bunch of that but it's the best I have for a starting point for Bad Maths.
Patreon is 23.4% of her income.
That means 1% is minimum £1,520 and maximum £3,406.67.
Brand deals 45% = £68,400 / £193,800
Adsense 21.9% = £33,288 / £94,316
Patron 23.4% = £35,568 / £100,776
Affiliates 6.6% = £10,032 / £28,424
Podcast 0.8% £1,216 / £3,445
Merch 2% £3.040 / £8,613
Writing 0.2% £304 / £861.33
Total £151,848 / £430,236
Last year worked out at £203,626 / £576,942 so "lost one third of my income" is surprisingly accurate for the higher figure - a little out on the lower one but close enough.
If anyone wants to check my maths, I won't take offence and I'll point out again that I'm in the wrong job.
