Variable pay

Pay and remuneration
What is variable pay?

Variable pay is the at-risk portion of remuneration that moves with performance or results: commissions, bonuses, incentives and profit shares. The ratio of fixed to variable pay (the pay mix) sets how much of a person's income depends on outcomes.

Pay mix, the real design decision

An 80/20 mix says the role is mostly about showing up skilled; a 50/50 mix says the outcome is the job. The mix should track two things: how much the individual genuinely controls the result, and how measurable the result is without distortion. High variable pay pointed at metrics people can game produces exactly the gaming it pays for, which is a design failure, not a character one.

The forms variable pay takes

Individual commission for direct revenue roles; short-term incentives (annual bonuses) against individual, team or company scorecards; long-term incentives (equity, multi-year cash) for senior roles where this year's decisions land in three years; profit sharing and gainsharing where collective results are the honest unit; and spot bonuses for recognition. Most organisations run several at once; the discipline is knowing which behaviour each is buying.

Making variable pay actually motivate

Three conditions, all necessary: line of sight (people can see how their work moves the metric), credibility (the plan pays what it implied, on time, without retrospective fiddling) and materiality (the amount at stake is worth changing behaviour for). Plans missing any of the three converge on the same outcome, variable pay treated as an unreliable salary component, resented when absent and unmotivating when present.

Common questions

Is variable pay superannuation-bearing in Australia?

Commissions and performance bonuses form part of qualifying earnings (the super base under the payday super rules), so the superannuation guarantee applies to them; under the 2026 rules this covers all commissions. Purely overtime-linked bonuses generally sit outside. Payroll settings should reflect it.

What is a good fixed-to-variable ratio?

Whatever matches the role's control over outcomes: heavy variable for direct revenue ownership, modest variable for shared outcomes, and near-zero for roles where measurement would distort the work.
