Build an all-in labour rate

Enter the base hourly wage for each trade and grade you employ, taken from the working rule agreement or your own payroll rather than a round guess.

لماذا: Starting from the real agreed wage is what makes everything above it defensible. A rate built on an invented base is wrong no matter how careful the on-costs are.

Layer on the on-costs that turn a wage into an employment cost: holidays and public holidays, pension, employer taxes and insurances, sick pay, training levy, travel and allowances.

لماذا: These on-costs commonly add a third or more to the wage. Leaving any of them out understates the cost of every hour of labour in every rate you build on top.

Divide the burdened annual cost by the hours actually spent on the tools, after taking out holidays, training, travel and downtime, to get the all-in rate per productive hour.

لماذا: You pay for the whole year but only sell the productive hours. Dividing by paid hours instead of productive hours is the subtle error that leaves margin on the table on every job.

Feed the all-in rate into the assemblies that build your unit rates, so labour flows into every price from one maintained figure rather than a number retyped per line.

لماذا: One rate in one place means a wage award or an insurance change updates every price at once. It also kills the inconsistency of different labour rates hiding across the same bill.
