Employee Cost Calculator
Calculate the true cost of a bad hire, including recruiting, onboarding, lost productivity, and replacement costs. Understand the financial impact of hiring mistakes.
Open the CalculatorThe Bad Hire Cost Calculator measures the financial impact of hiring the wrong person — distinct from the Hiring Cost Calculator (one-time cost to fill any position) and the Employee Turnover Cost Calculator (cost of losing any employee). It adds up nine components: original recruiting, interview, onboarding, and training sunk costs; lost productivity during the failed tenure; manager time spent coaching; severance; and the cost to recruit and onboard a replacement.
Lost productivity is usually the largest single component. It is calculated as (annual salary ÷ 12) × (100% − productivity percentage) × months employed. An employee performing at 50% of expected output for six months on an $80,000 salary loses roughly $20,000 in unrealized work value. The productivity percentage represents how much of the expected output the employee actually delivered.
Manager time cost equals the hours spent managing, coaching, and correcting the underperformer multiplied by the manager’s hourly rate. Severance or termination expense covers any separation payment. Both are direct, quantifiable costs of the failed tenure.
After the bad hire leaves, the position must be refilled. Replacement recruiting and onboarding costs are added on top of the original sunk costs, because the original hire’s recruiting and onboarding spend produced no lasting return.
Total cost of a bad hire is the sum of all nine components, and the calculator shows the total as a percentage of annual salary. A bad hire costing 150% of annual salary is not uncommon. This estimate does not include intangible costs: damage to team morale, lost client relationships, damage to company reputation, and the opportunity cost of time spent on the failed hire. For the cost of losing any employee (not just an underperformer), use the Employee Turnover Cost Calculator.

A bad hire is an employee who does not meet the performance expectations of the role — whether because of skills mismatch, poor cultural fit, attitude problems, or misconduct. The financial impact includes sunk recruiting and onboarding costs, the value of work the employee never produced, manager time spent coaching and correcting, severance, and the full cost to recruit and onboard a replacement.
A bad hire commonly costs 30% to 150% of the employee’s annual salary, and for senior or revenue-generating roles the figure can exceed 200%. The largest single component is usually lost productivity — an employee performing at 50% of expected output for six months on an $80,000 salary loses roughly $20,000 in unrealized work value alone.
Lost productivity cost = (annual salary ÷ 12) × (100% − productivity percentage) × months employed. For an $80,000 employee at 50% productivity for 6 months, the monthly salary is $6,667, the monthly loss is $3,333, and the total lost-productivity cost is $20,000. The productivity percentage represents how much of the expected output the employee actually delivered.
The calculator measures direct, quantifiable costs. It does not capture intangible costs that are real but hard to price: damage to team morale and engagement, lost client relationships and goodwill, harm to company reputation, knowledge drain, and the opportunity cost of time spent on the failed hire. The true total cost of a bad hire is almost always higher than the estimate.
The Bad Hire Cost Calculator focuses on underperformance — it includes lost productivity during the failed tenure and manager time spent coaching. The Employee Turnover Cost Calculator measures the cost of losing any employee and replacing them — separation costs, vacancy cost while the role is open, and ramp-up productivity loss for the replacement. Use the bad hire tool when the issue is underperformance; use the turnover tool when the issue is attrition.
