Formula used
Current gross baseline = current basic + current DA + current HRA + current transport allowance. Revised basic scenario = current basic × selected fitment factor. Projected gross = revised basic + projected DA + projected HRA + projected transport allowance. Current DA is not added to revised basic a second time.
Example calculation
For current basic pay of ₹44,900, 60% current DA, 30% current HRA and ₹3,600 transport allowance, current gross is ₹88,910. A 2.57× scenario gives revised basic of ₹1,15,393. Projected allowances are then applied separately.
How to use this calculator
- Enter current basic pay from the latest payslip.
- Confirm current DA and select the current X, Y or Z HRA category.
- Enter current transport allowance to build the gross baseline.
- Choose a fitment-factor scenario; none is labelled official.
- Choose a projected X, Y or Z HRA scenario and review its monthly and annual difference.
- Open advanced assumptions only if you want to model projected DA or transport allowance.
- Compare revised basic separately from gross-to-gross change.
Important assumptions
- All fitment factors are illustrative user-selected scenarios, not official recommendations.
- Current DA defaults to the 60% rate effective 1 January 2026 and can be edited.
- Current HRA uses the 7th CPC DA-linked 30%, 20% and 10% X/Y/Z rates.
- Projected DA, HRA and transport allowance are independent assumptions because 8th CPC values are not notified.
- Other allowances, deductions, pension, NPS, tax and arrears are excluded.
Common mistakes to avoid
- Adding current DA to basic before applying the fitment factor and thereby counting DA twice.
- Treating a media or employee-body demand as an official fitment factor.
- Comparing revised basic with current gross instead of showing basic-to-basic and gross-to-gross separately.
- Assuming an implementation date, arrears period or revised HRA without a government notification.
Official status of the 8th Central Pay Commission
The Government of India constituted the 8th Central Pay Commission through a notification dated 3 November 2025 and gave it 18 months to submit its report. The official site does not publish a final fitment factor, pay matrix or implementation date. This page therefore labels every future-pay input as a scenario.
Why current DA must not be counted twice
Current DA is part of today's gross salary. The fitment scenario is applied once to current basic pay to estimate revised basic. Projected DA is then a separate assumption on revised basic and defaults to zero. This keeps the current baseline and future scenario mathematically distinct.
Basic-to-basic versus gross-to-gross
A fitment factor produces a revised-basic scenario, not an in-hand salary. The gross comparison adds only the projected allowances entered by the user. Tax, NPS, CGHS, pension, other allowances and arrears are outside this calculator.
Current versus projected government HRA
The calculator keeps current 7th CPC X/Y/Z HRA separate from a user-selected projected X/Y/Z scenario, then shows monthly and annual HRA differences. This is government salary HRA, not the income-tax HRA exemption calculation, and no 8th CPC HRA rate is treated as official.
Source and Methodology
Last reviewed: 22 August 2026
The status and constitution date come from the official 8th CPC website. Current DA is based on the PIB approval effective 1 January 2026. Current HRA categories follow the PIB-published 7th CPC DA-linked escalation. Calculation version 2026-08-17.2 is covered by DA double-counting and HRA monthly-to-annual regression tests.
Calculation version: 2026-08-17.2 · Facts checked: 2026-08-22
Next review trigger: Official 8th CPC report, pay matrix, fitment factor, allowance rule or implementation notification; or a new central DA order.

How this calculator builds its scenarios
It first builds a current 7th CPC gross-pay baseline, then applies your selected fitment factor once to current basic pay. Projected DA, HRA and transport allowance are separate scenario inputs, so current DA is not counted twice.
8th Pay Commission salary at 1.92×, 2.08×, 2.57×, 2.86× or 3.00×
These are comparison scenarios, not notified fitment factors. Enter current basic pay and switch between the available factors to see how revised basic changes while projected DA, HRA and transport allowance remain separate assumptions.
How do DA and HRA affect an 8th CPC salary estimate?
Current DA and current HRA belong to the current-pay baseline. A fitment-factor scenario is applied to current basic pay, while projected DA and projected HRA are entered separately. This avoids counting current DA twice and avoids presenting any future allowance as official.
