Pay Rises Arrive Mid-Year
A rate set in January is wrong from April. How to handle a pay award inside a rate, and why the answer is a dated version rather than a blend.
A pay award landing in April makes every rate set in January wrong from April onward. The two usual responses — leave it until the next annual rebuild, or blend the old and new wage across the year — are both defensible and both produce a number that was never true on any particular day.
The pay question in “Pay Rises Arrive Mid-Year” needs a visible chain from working time to approved payroll input. Used for employee monitoring software with screenshots, explore the published reporting options can organise the operational time record, while statutory calculations, deductions and final payroll decisions remain in the appropriate payroll system.
The better answer is a dated version: one rate before the award, one after, each labelled.
As an outside benchmark for “Pay Rises Arrive Mid-Year”, see IFRS Foundation resources. Keep the source record, calculation rule, approval and resulting decision visible as separate steps.
Why leaving it is wrong
Because every job costed after April is understated by the award percentage, and quotes built from those costs carry the error forward into the following year.
A three per cent award left unapplied for eight months understates every job costed in those months, and the error travels into next year's quotes through the history they are built from.
A three per cent award left for eight months is a two per cent understatement across the whole year's work.
Why blending is wrong
A blended rate is a number that was correct on no day of the year. Jobs before the award are overstated and jobs after are understated, by amounts that depend on when they fell.
It balances in total and is wrong on every job, which is the opposite of what costing is for.
The dated version
Rate A from January to March, rate B from April. Both published, both dated, both built from the same template.
Jobs are costed at the rate in force when the hours were worked, which is what actually happened.
What it costs to run
Almost nothing, once the build-up is a spreadsheet rather than a habit. Change one input, re-run, save with a date.
The work is not the arithmetic; it is having the build-up written down in the first place, which is the subject of this whole section.
Jobs that span the change
Hours before the date at the old rate, hours after at the new. Most job systems can do this if asked and almost none do it by default.
Where the system cannot, the honest approximation is to use the rate in force at the midpoint of the hours and to note it.
Quotes already issued
Not affected by the award unless the contract says so. A quote is a price; a rate change is a cost change, and the gap lands in margin.
Knowing in advance how much work is quoted at the old cost base is a useful number to have in the week the award is agreed.
Awards known in advance
Most are: a settlement date, a negotiation timetable, a statutory minimum that moves on a known date. The rate's review date can be set to follow them rather than the financial year.
Reviewing in January when awards land in April is a calendar inherited from somewhere else.
The statutory minimum
Moves on a fixed date in most jurisdictions and compresses differentials: the lowest grade rises, and the grades above it either rise too or the structure flattens.
Both outcomes change the rate. The second one changes it in ways that are easy to miss because no individual award was announced.
Backdated awards
Agreed in July, effective from April. The cost belongs to April onward, and the cash lands in July.
Costing it from July repeats the bonus timing problem, and the remedy is the same: accrue from the effective date, reconcile on payment.
What to write next to the rate
"Effective 1 April 2026; supersedes the rate of 1 January 2026; change is the 3.4% award." One line.
It makes the series readable, it tells anybody comparing two job costs why they differ, and it stops the annual question about whether the rate has been updated.
Different awards on different dates
Common in organisations with several agreements: one group settles in April, another in October, a third follows a statutory date.
Three effective dates mean three dated rate versions for three groups, which sounds like administration and is one spreadsheet with a date column. The alternative — a single annual rebuild — leaves two of the three groups wrong for most of the year.
What to tell the people who quote
That the rate changes on a known date, what the change is, and what happens to quotes issued before it.
Without that, quoting carries on at the old rate for weeks after the change, and the gap lands in margin without anybody choosing it. A note in the quoting tool a fortnight before the date is the whole mechanism.
Keeping the old versions
Every superseded rate, with its dates, kept. Reconstructing what a job should have cost two years ago is impossible without them, and it is asked for more often than anybody expects — usually in a dispute.
