Basic pay is one component
Identify the level and applicable cell from the appointment or recruitment documents. The entry cell shown by a calculator is not necessarily the pay for every employee at that level. Increments, promotion rules, appointment conditions and later orders can alter basic pay.
Build an estimate transparently
A simplified monthly gross model adds basic pay, DA calculated at the applicable rate, HRA at the applicable city category, and eligible fixed allowances. A take-home estimate subtracts employee contributions and other deductions. Pay periods, tax, transport allowance, government accommodation and NPS coverage can change the result.
NPS and current orders
Where the employee contribution rule applies, the estimator on this site uses the requested 10% of Basic + DA assumption for Tier-I. Verify coverage, contribution base and payroll treatment with the employer's current order; don't treat this formula as a universal pay rule or pension advice.
Use the salary calculator for arithmetic only. It cannot issue an official pay slip.
