Calculate your 7th Pay Commission pay today — basic, 60% DA, HRA, transport allowance, NPS and tax — and model the 8th Pay Commission with your own fitment factor, DA reset, HRA and arrears. The 8th CPC has not announced any fitment factor; the results are scenarios, not forecasts.
Monthly gross = basic + DA + HRA + transport allowance (+ DA on TA) + other allowances.
The commission recommends a fitment factor — a multiplier applied to existing basic pay to get the new basic. The calculator multiplies your basic by the factor you enter and rounds to the nearest ₹100 (pay-matrix cells are multiples of ₹100). Under earlier commissions DA restarted at zero on revision and HRA restarted at lower base rates; the calculator follows that pattern by default, and you can change both.
Because DA resets, the effective rise in gross pay is lower than the fitment factor suggests. With a basic of ₹56,100 (Level 10, X-class city) and a fitment factor of 2.28 the new basic is ₹1,27,900, but the gross moves from ₹1,18,110 to ₹1,65,796 a month at zero DA — and the fitment factor that merely keeps today’s gross unchanged is about 1.59.
If the commission’s pay applies from 1 January 2026 but is implemented later, you receive arrears for the gap: the difference between the new pay and what you drew. The calculator sums the monthly difference using the DA path you set for both scales. Arrears are taxable in the year received; you can claim relief under section 89 (Form 10E) — see our salary arrears relief calculator.
Income tax uses the Tax Year 2026-27 slabs: new regime nil up to ₹4 lakh, 5% to ₹8 lakh, 10% to ₹12 lakh, 15% to ₹16 lakh, 20% to ₹20 lakh, 25% to ₹24 lakh, 30% above; ₹75,000 standard deduction; rebate up to ₹12 lakh of taxable income; 4% cess.
60% of basic pay from 1 January 2026. The next revision, due from 1 July 2026, depends on the AICPI-IW index and the Cabinet decision; update the DA fields when it is announced.
It has not been announced. The 7th CPC used 2.57. Published estimates for the 8th CPC range from about 1.8 to 3.0; use the calculator to test different values.
Recommendations are widely reported to take effect from 1 January 2026, but the commission has 18 months to report and the Government decides the implementation date. Arrears would cover the gap.
It did after the 6th and 7th commissions, when accumulated DA was merged into the new basic via the fitment factor. The calculator assumes DA restarts at the percentage you enter (default 0%).
With DA at 50% or more: 30% for X-class cities, 20% for Y and 10% for Z. Minimum HRA is ₹5,400, ₹3,600 and ₹1,800 respectively.

Scope: Monthly pay of a central government employee on the 7th CPC and under a user-defined 8th CPC scenario, with arrears, tax and a 10-year projection.
The calculation engine was checked against an independently written reference implementation across 10,368 pay-commission input combinations, and against published figures where the scheme publishes them. Review date: 5 October 2026.
