Payroll & Salary Calculations

Understanding the true cost of an employee starts with payroll numbers.

  • Gross Salary – Includes basic pay, allowances, bonuses, and incentives. Total earnings before deductions.
  • Net Salary – Take-home pay after deductions such as PF, TDS, ESI, or professional tax.
  • Cost to Company (CTC) – Total expense the employer pays, including employer PF, gratuity, insurance, and benefits.
  • Overtime Pay – Calculated using hourly rate multipliers (1.5x or 2x) for extra working hours.
  • Leave Encashment – Unused leaves converted to cash using basic salary formula (Basic/26 × Unused Leaves).

Recruitment Metrics & Hiring Costs

Hiring is one of the biggest expenses for companies. Measuring recruitment efficiency is critical.

  • Cost per Hire – Total recruitment expenses divided by number of hires.
  • Offer Acceptance Rate – Percentage of candidates who accept job offers. Higher rate indicates strong employer branding.
  • Selection Ratio – Hiring competitiveness measured by comparing applicants to hires.

Employee Performance & Productivity

After hiring, measuring performance is essential.

  • Employee Productivity – Output divided by input to understand workforce efficiency.
  • Revenue per Employee – Key business performance indicator showing revenue generated per employee.
  • Absenteeism Rate – Lost workdays due to absences. High absenteeism reduces productivity and increases costs.
  • Turnover Rate – Frequency of resignations. Tracking helps improve retention strategies.
  • Retention Rate – Percentage of employees who stay with your company over time.

HR ROI & Financial Analysis

Training and workforce investment should generate returns.

  • Training ROI – Compare training benefits with costs to evaluate effectiveness.
  • Human Capital ROI – Profit remaining after operating and employee costs, measuring workforce investment payoff.
