Which fitment factor should I select?

Actual salary and arrears may therefore differ substantially from the figures generated by this calculator.

This calculator does not include HRA, Transport Allowance, increments, promotions, deductions, income tax or other components of an employee’s salary unless specifically stated. Users should refer to official Government orders and notifications before making any financial or service-related decision based on these estimates.
