Amy is a sales person for your company and she earns her pay based on commission. Amy's pay is known as variable pay or what other term?

Fixed pay is the opposite of commission pay - it refers to guaranteed compensation that does not change based on individual performance.

'Commission only' describes the payment mechanism but is not the formal HR classification term used to categorize this type of variable compensation structure.

Base pay refers to the guaranteed, fixed salary component of compensation - the direct opposite of variable or at-risk pay.

Commission-based pay is formally classified as 'at risk pay' because the employee's earnings are not guaranteed and fluctuate entirely based on achieving measurable performance targets. The income is considered 'at risk' since poor performance directly reduces or eliminates compensation. This term distinguishes variable pay from fixed or base pay in total compensation frameworks.
