The true cost of a bad hire

1. Recruitment and onboarding: the cost you enter.
2. Lost productivity: annual salary ÷ 12 × months × productivity reduction. Only the unproductive share of salary is counted, so pay and lost output are never counted twice.
3. Replacement recruitment: the cost you enter.
4. Project delay: weeks of delay × your weekly delay cost. If your weekly figure already includes staff costs, reduce the productivity figure to avoid overlap.
5. Additional training and other measurable costs: as entered.

Low and high scenarios adjust only the uncertain inputs: months (× 0.75 and × 1.25), productivity reduction (× 0.75 and × 1.25, capped at 100%) and delay weeks (× 0.5 and × 1.5). Fixed costs stay as entered. There are no hidden multipliers.
