Over five or ten years the cumulative difference can be substantial, even when the step from Probation Band 3 to the next band looks modest year to year. This tool compares gross earnings under two promotion timings using illustrative pay from HMPPS pay (Prison & Probation).
Typical progression for Community Payback Supervisor
Progression may include senior Community Payback posts or wider Probation Service grades. Confirm with your employer.

Real world factors
Promotion depends on vacancies, performance, funding and policy. The calculator does not model competition for posts or time to complete training. Use it for financial comparison alongside career planning conversations with your line manager or union.
