This changes how your tax is worked out further down.
02
What the job costs you
Direct costs£
Everything you buy in for this job — parts, timber, fixings, skip hire, waste disposal.
%
Contingency added£0.00
Covers price rises, breakages and the bits you always forget. 5–10% is normal.
hrs
£
Value of your own labour£0.00
Price your own time, always. Your labour is a real cost of the job even though HMRC doesn't treat your own drawings as a business expense. Leaving it out is the fastest way to work for nothing.
£
Labour you pay out for — subbies, labourers, an extra pair of hands for the lift.
£
£
Parking, congestion charge, fuel for this job, building control fees, permits.
03
Overheads this job must carry
Fixed costs£
Van, insurance, tools, phone, accountancy, advertising — the costs you pay whether you're on site or not.
£
hrs
Overhead per billable hour£0.00
Most full-time trades bill 1,200–1,600 hours a year once you strip out quoting, admin, travel and holiday.
04
Your mark-up
Profit on top%
Added on top of your costs. 15–30% is typical for domestic work.
%
The slice of the final price that is profit. We'll work the price backwards for you.
Mark-up and margin are not the same number. A 20% mark-up on £1,000 of cost gives a £1,200 price — and £200 profit on £1,200 is a 16.7% margin. Quote off mark-up, judge yourself on margin.
05
Tax & VAT
What to set aside£
Your best guess at profit for the whole tax year. This tells us which tax band this job lands in — the same job costs you more tax at £60k than at £20k.
£
Corporation Tax is 19% up to £50,000 of profit and rises to an effective 26.5% between £50,000 and £250,000, so where this job sits matters.
I'll draw this job's profit out as a dividend
£
Personal income you'll already have taken this year (salary plus dividends). Used to work out the dividend tax on top of Corporation Tax.
I'm VAT registered (add 20% to the invoice)
VAT isn't your money — you collect it and pass it to HMRC. Registration is compulsory once turnover passes £90,000 in any rolling 12 months.
