Yeah but £36 a day for how many hours work? I guess an average of 1-2. So pro-rata you're onto a cushy number - with plenty of time left to go fishing, write the all american novel or post on a plumbing forum.
Fair point!
344.6 direct working hours
At least 400 hours for travel, chatting to customers, "could you just jobs", etc
And, in case you're wondering
Charge to customer per hour: £31.51
Out of this I receive £26.11 per hour gross (labour plus profit on stock sold) (£31.51 minus travel time costs)
Taken down to £16.66 per hour after some costs e.g. motor and travel, advertising, sundries, etc, etc
This will come down further due to remaining costs not yet taken into account. For example, depreciation, office use, insurance, clothing, etc as they're calculated at the end of the year.
This takes the £16.66 down to say to around £10.80 per hour.
£10.80 x 7.5 = £81 per day
= £405 per week = £19,440 (48 weeks)
£19.5k is the maximum because we all have days where we're ill, family commitment, customer not in or cancelling at the last minute, delivery late, etc, etc.
I've not typed this to prove a point - just I've never worked out these figures before despite taking time to record the necessary information!
