What a day of you really has to cost.
If you're charging two-fifty a day, you might be paying to go to work. I was. So here's the sum nobody showed me. My numbers are in the boxes. Change them to yours. It adds itself up.
The wage you'd want if you worked for someone else. Before tax, same as any wage.
For a whole year. Before you've earned a penny.
Every weekday in the year. Then take these off. Be honest.
188 days at £250 is £47,000 in. Take off the £23,600 it costs to exist.
That leaves £23,400. Before tax.
You're £152 a day short. So it's not cheap. It's you paying them.
This is your labour, mate. Materials go on top, and the VAT if you're registered.
Do it again every year. The van and the diesel don't stay still, so your rate shouldn't either.
