8th Pay Commission: Railway union proposes 5-fitment-factor formula; salaries may jump over 400% — check calculator

The Indian Railway Technical Supervisors' Association (IRTSA) has proposed an unique change to salary revision norms under the upcoming 8th Pay Commission, urging the Centre to adopt separate fitment factors for different employee categorie instead of a common multiplier for all levels.

The railway employees' body proposed a total of five fitment factors ranging from 2.92 to 4.38 to ensure a more balanced salary structure across lower, middle and senior-level employees.

This as goes:

Level 1-5 - 2.92

Level 6-8 - 3.50

Level 9-12 - 3.80

Level 13-16 - 4.09

Level 17-18 - 4.38

This proposal, if accepted, may result in a salary hike over 400% for few employees

What is fitment factor?

A fitment factor is a mathematical multiplier used by the Central Pay Commission to convert an employee's pre-revised basic salary (or pension) into the new, revised basic salary structure.

How the calculator is used?

Following the fitment factor calculator is crucial because any change in the multiplier directly impacts salaries, pensions, increments and related arrears.

.The primary formula used is:

Current basic pay x fitment factor = New basic pay

Here’s the likely jump in salaries if the recommendation is implemented:

Level 1-5 employee

For instance, if an employee currently earns a basic pay of ₹20,000, a fitment factor of 2.92 would raise it to ₹58,400.

₹20,000 × 2.92 = ₹58,400

Level 6-8 employee

If the current basic pay is ₹45,000 and the proposed fitment factor is 3.50, the revised pay will be ₹1,57,500

₹45,000 × 3.50 = ₹1,57,500

Level 13-16 employee

If an employee’s current basic pay is ₹1,20,000, applying the proposed fitment factor of 4.09 would increase it to ₹4,90,800.

₹1,20,000 × 4.09 = ₹4,90,800

Level 17-18 employee

Similarly, if an employee’s current basic pay is ₹2,50,000, applying the proposed fitment factor of 4.38 would raise the revised basic pay to ₹10,95,000.

₹ ₹2,50,000 × 4.09 = ₹10,95,000

Fitment factor calculation

The concept of the fitment factor became became a talking point during the 6th and 7th Pay Commissions, as earlier pay panels followed more complex approaches to revise salaries, including pay rationalisation, dearness allowance mergers, and need-based wage calculations.

How earlier pay panels worked

It would not be accurate to apply the modern concept of a ‘fitment factor’ to the first five pay commissions. Earlier commissions revised salaries through broader restructuring methods, and there was no single uniform multiplier used across the system. However, the core objective remained the same — aligning government pay structures with prevailing economic conditions and administrative requirements.

What is the significance of the 8th Pay Commission?

The 8th Pay Commission is significant because it is expected to affect more than 1.1 crore beneficiaries, including central government employees and pensioners, as well as their families.

So far, India has witnessed seven pay commissions. The First Pay Commission was established in January 1946, and since then, a new pay commission has generally been constituted every 10 years. The 8th Pay Commission was constituted on 3 November 2025.
