Ok, so say a gardener or cleaner charges £20 per hour.
they are unlikely to be able to work all the hours 9-5, as often it will be 2 hours here, pack up, drive, 2 hours at next job. If you work hard and juggle well you might land large gardens who need a full day every week, but those are rare.
so if I work 5 days a week, maybe 2 full day 8 hrs gardens and 6 part day gardens at 3 hours each, and a half day for admin. You’ve got a max of 34 hours to bill in the week. 34 x £20 = £680.
I can’t work 52 weeks a year, I’d like holiday time, so if we take out 6 weeks that’s 46 weeks to work in the year, £680 x 46 = £31,280
Out of that I have to buy all tools and gloves, kit etc. £1000 (low because I don’t use big tools on the whole. Insurance £100. Website £200. Advertising I barely need as it’s word of mouth. So net profit call it £30,000
NI cat 2: £163
NI Cat 4: £1760
Tax: £34860
pension: £2400 (probably need to up this)
take home £22,000 - If it doesn’t rain for weeks on end, or get too cold to work. Which it does. I probably loose about 6 weeks a year to weather. If I get flu or whatever I get no pay.
