Methodology

How It Is Estimated

A transparent explanation of the calculation used by the salary and pension tools. These are planning scenarios, not official 8th CPC rates.

Salary calculation

Step by step

01Choose current pay Select a pay level/cell or enter your current basic pay.
02Apply fitment Estimated new basic = current basic × selected fitment factor.
03Add DA Estimated DA = new basic × selected DA percentage ÷ 100.
04Add HRA Estimated HRA = new basic × selected HRA percentage ÷ 100.
05Add transport The entered transport allowance is added to the estimated gross.
HRA choices

10% · 12% · 15% · 20% · 30%

The HRA dropdown is intentionally visible so users can test different assumptions rather than having the rate hidden in the formula.

Important

Fitment factor, implementation DA, HRA, transport and other allowances may differ when official rules are notified.

Pension

Pension estimate logic

Revised basic pension is modelled as current basic pension × selected fitment factor. DR and age-based additional pension are then shown as separate components.
