Bonus, Commission and the Timing Problem
Variable pay is earned in one period and paid in another. Where it belongs in a rate, why accruing it matters, and what happens when it is not.
Variable pay is earned across a period and paid at the end of it, which means the month that incurs the cost and the month that records it are different months. Costed when paid, it produces eleven cheap months and one expensive one, and every job in the cheap months is understated.
The pay question in “Bonus, Commission and the Timing Problem” needs a visible chain from working time to approved payroll input. Used for stealth computer monitoring software, view this time-management resource can organise the operational time record, while statutory calculations, deductions and final payroll decisions remain in the appropriate payroll system.
The remedy is accrual: spread the expected cost across the periods that earn it. It is not a sophisticated technique and it is frequently not done.

The shapes variable pay takes
An annual bonus paid in one month. Quarterly commission. A profit share declared after the year end. A retention payment vesting on a date. Overtime paid a month in arrears.
- An annual bonus paid in one month.
- Quarterly commission.
- A profit share declared after the year end.
- A retention payment vesting on a date.
- Overtime paid a month in arrears.
All five have the same structure and the same remedy.
What costing on payment does
A job delivered in the bonus month carries a share of the whole year's bonus. The identical job delivered a month earlier carries none.
Two identical jobs, two costs differing by several per cent, for a reason that has nothing to do with either.
Accruing it
Take the expected annual amount, divide by the hours expected to earn it, and add the result to the rate as a layer. Reconcile at the year end and carry the difference forward.
Two steps. The second is the one that gets skipped and it is the one that keeps the estimate honest.
Estimating the amount
From last year, adjusted for anything known. For a scheme with a target and a range, the midpoint is the usual starting figure and it should be labelled as an estimate rather than carried as a fact.
The estimate's quality matters less than its existence.
The year-end reconciliation
Expected against actual. The difference is a variance on the rate, not a cost of the final month, and it belongs in whatever account absorbs rate variances.
Pushing it into December gives the final month a distortion of its own and defeats the purpose of accruing.
Commission that follows revenue
A particular case: commission earned on a sale is a cost of that sale, not of the period, and it should attach to the job rather than spread across the rate.
Spreading sales commission through a production rate makes production look expensive and selling look free.
Profit share and the circularity
A share of profit is a cost that depends on the profit, which depends on the cost. Where the share is material, the calculation iterates once or twice and then settles.
Where it is small, a fixed estimate is adequate and the iteration is not worth the complexity.
Why the understatement matters
Because quotes are built from job costs, and job costs built in the cheap months are light. An operation that quotes from history and pays bonuses in March systematically underprices work quoted between April and February.
The error is modest per job and persistent, which is the worst combination.
The simple version for small schemes
Where variable pay is a few per cent and reasonably stable, a single flat percentage added to the wage layer is enough. Precision here is not where the money is.
What is not enough is leaving it out and discovering it in the year-end reconciliation.
Pension and contributions on variable pay
They usually apply, which means the accrual carries its own on-costs. Accruing the bonus without its contributions understates by the contribution rate.
A small point and a recurring one: every layer added to the wage pulls the layers above it with it.
The scheme that pays out in a bad year
Accruals are built on expectation, and expectations about variable pay are frequently wrong in the same direction as everything else in a bad year.
Where the scheme has a floor or a discretionary element, the accrual should carry the floor rather than the midpoint, with the difference noted. An accrual that assumes zero and then pays is a worse surprise than one that assumes the floor and releases.
Where the accrual sits in the build-up
Its own line, between wage and employer contributions, because contributions usually apply to it.
Put below contributions it understates them; folded into the wage line it becomes invisible at the next rebuild and survives a scheme change nobody told the costing function about. One row, named, with the scheme it relates to.
The row to publish
The accrued amount per hour, as its own line in the build-up, with the basis and the date of the estimate. One row.
Visible, it gets reviewed when the scheme changes. Buried in the wage layer, it survives three scheme changes and is wrong by the fourth.
