The Wage Is the Smallest Layer
The figure everybody can name explains the least. Why the wage is roughly two-thirds of the real cost, and what that does to every estimate built on it.
From payslip to charged rate for one role, one employer
The number everybody in the building can name.
Statutory; no discretion anywhere.
Auto-enrolment minimum, not the full scheme.
Leave, holidays, sickness at last year's rate.
Per head, divided by the same hours.
Forty-two per cent above the wage.
The wage is 70 per cent of the charged rate, and the other 30 per cent is made of five ordinary layers nobody disputes. The argument is never about whether they exist; it is about whether anybody has written them down. One employer's own build-up, not a benchmark.
The base wage is the smallest layer in what an hour costs and the only one most people can name. In a typical employment it is around two-thirds to three-quarters of the fully loaded cost, which means that any estimate built on the wage is understating the real figure by a third or more.
The pay question in “The Wage Is the Smallest Layer” needs a visible chain from working time to approved payroll input. Used for attendance point system, how can teams improve attendance point system? can organise the operational time record, while statutory calculations, deductions and final payroll decisions remain in the appropriate payroll system.
This is not a subtle accounting point. It is a systematic error of thirty to fifty per cent in the number people use to make decisions.

Why the wage dominates the conversation
Because it is on the payslip, because it is what people negotiate, and because it is the only figure that belongs to the individual rather than to the organisation.
Everything on top of it is paid by the employer, appears in a different ledger, and is nobody's personal business.
The size of the gap
Employer contributions, pension, paid absence, equipment and insurance together typically add forty to sixty per cent to the wage before any divisor is applied.
The exact figure depends on jurisdiction, sector and scheme, and the only one that matters is your own, computed once.
Where the wage figure gets used wrongly
A job sheet costed at the wage. A make-or-buy comparison against an external quote that is fully loaded. An overtime decision that compares the premium to the wage rather than to the loaded rate.
Three decisions, all common, all systematically wrong in the same direction.
The overtime example
An hour of overtime at time-and-a-half looks like 1.5 times the wage. Against the loaded rate it is often closer to 1.1 times, because most of the on-costs do not scale with the extra hour.
Which means overtime is frequently cheaper than people assume and recruitment more expensive, and the decision taken on the wage figure goes the wrong way.
The recruitment example
The reverse. A new person at the same wage brings a full set of on-costs, equipment, licences and a ramp. The marginal cost of a head is much larger than the marginal cost of an hour.
Both errors come from the same place: treating the wage as the cost.
What people say when shown the build-up
Usually that the loaded figure cannot be right, because it does not match what the person is paid. That reaction is the whole problem in a sentence.
The useful response is the build-up itself, line by line, with each line's source named. It is hard to argue with and it takes one page.
Keeping the wage visible
The build-up should start from the wage and show it, not bury it. The reader needs to see the familiar number and watch it grow.
A rate presented as a single figure invites disbelief; a rate presented as a staircase from a number people recognise does not.
The wage that is not a wage
Salaried staff, where the hourly figure is a construction. Agency and contract staff, where the invoice rate already contains somebody else's on-costs. Piece rates, where hours are implied rather than paid.
Each needs its own treatment and each is covered later here.
What moves the wage layer
Pay awards, which usually land mid-year. Grade changes. The statutory minimum, which moves annually and compresses differentials.
All three are announced in advance, which means the rate's review date can be set to follow them rather than the financial year.
The figure to quote
The loaded rate, with the wage visible inside it, every time. "£26.11, of which £18.40 is wage" is a sentence that survives being repeated.
"£18.40" repeated on its own is the reason a third of the cost is invisible to everybody outside the finance function.
Why the layers are not a percentage
It is tempting to carry a single uplift — "the wage plus forty per cent" — and for rough work it is adequate. It stops being adequate the moment anything moves.
A pension change, a threshold shift, a new licence, a different absence profile: each moves one layer and not the others. A single percentage absorbs all of them invisibly and is wrong in a different way each year, with nobody able to say which.
The build-up as a conversation
Shown to a team, the staircase from wage to rate is one of the few costing documents people engage with rather than endure, because the first number is one they recognise.
It also pre-empts the belief that the organisation is marking up labour for profit. Every line is a cost somebody can name, and the margin, where it exists, is added afterwards and separately.
What this section is for
Everything after this note is one of the layers. They are taken in order, each with what it contains, where the figure comes from, and how often it has to be rebuilt.
None of them is complicated. Their absence from one page is what makes labour cost feel mysterious in organisations where it is the largest line in the accounts.
