Build an all-in labour rate
Turn a base wage into a true cost per productive hour by adding on-costs and dividing by the hours actually worked, then feed that rate into the assemblies that build your unit rates.
Cách hoạt động, từng bước một
4 bước xuyên suốt nền tảng - bạn làm gì ở mỗi bước và vì sao điều đó quan trọng.
Enter the base wage
Đơn giá nhân côngEnter 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.
Tại sao: 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.
Add the on-costs
Đơn giá nhân côngLayer 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.
Tại sao: 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 by productive hours
Đơn giá nhân côngDivide 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.
Tại sao: 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.
Use it in the assemblies
Tổ hợpFeed 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.
Tại sao: 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.
