Introduction: The Magic Number Everyone Is Waiting For
For over 50 lakh Central Government employees and 60 lakh pensioners, the “Fitment Factor” isn’t just a technical term—it is the magic multiplier that determines financial future.
When the 7th Pay Commission was implemented, that number was 2.57.
Now, as we approach the 8th Pay Commission (expected Jan 1, 2026), the buzz is around numbers like 1.96, 2.86, or even 3.68.
But where do these numbers come from? Is it random?
No. There is a precise scientific logic behind it involving inflation data (AICPI-IW) and a minimum wage formula established decades ago.
In this guide, we break down exactly how the Fitment Factor is calculated and what it means for your salary.
1. What is the Fitment Factor?
In simple terms, the Fitment Factor is a multiplier used to transition your salary from an old Pay Commission structure to a new one. It accounts for the inflation that has occurred over the last 10 years and resets your “Basic Pay” to a higher level.
The Formula:
$$New Basic Pay = Old Basic Pay \times Fitment Factor$$
- Example (7th CPC):If your Basic Pay was ₹7,000 (6th CPC), the 7th CPC multiplied it by 2.57.$$7,000 \times 2.57 = \text{₹}17,990$$ (Rounded off to ₹18,000).
2. The Core Logic: The Dr. Aykroyd Formula
The foundation of all Pay Commission calculations in India is the Dr. Wallace Aykroyd Formula.
The 7th Pay Commission (and likely the 8th) uses this “Need-Based Minimum Wage” method to determine the minimum salary required for a government employee to live with dignity.
The 3+1 Components of the Formula:
The formula assumes a standard family consists of 3 Consumption Units (Husband, Wife, and two children treated as 0.5 units each).
| Component | Requirement Standard |
| Food | Net intake of 2,700 Calories per adult per day. |
| Clothing | 66 meters (approx 72 yards) of cloth per year per family. |
| Shelter | Rent expenditure based on the minimum area provided by Government housing schemes. |
| Fuel & Misc | Calculated as 20% of the total minimum wage. |
| Social Needs | (Added by Supreme Court): 25% for medical, education, and recreation. |
How this creates the Fitment Factor:
- The Commission calculates the cost of these components using current market prices.
- This total cost becomes the Minimum Basic Pay.
- The Fitment Factor is then derived by dividing this New Minimum Pay by the Old Minimum Pay.
3. The Role of AICPI-IW (Inflation Data)
You often hear about AICPI-IW (All India Consumer Price Index for Industrial Workers) when checking your Dearness Allowance (DA). This same index is the “fuel” for the Fitment Factor.
- The Connection: The prices of the food, clothing, and fuel mentioned in the Aykroyd formula are tracked using AICPI-IW numbers.
- The 10-Year Gap: Since Pay Commissions come every 10 years, the government looks at how much the AICPI-IW index has risen from the start of the last commission (2016) to the start of the next (2026).
The “Merger” Effect:
Usually, when DA crosses 50%, it is effectively “merged” into the Basic Pay during a Pay Commission revision.
- Current Trend: If DA reaches 60-65% by Jan 2026, the 8th Pay Commission will likely recommend a Fitment Factor that subsumes this DA into the new Basic Pay, resetting DA to 0%.
4. 7th vs. 8th Pay Commission: The Scenario Analysis
Let’s look at how the numbers stack up. Unions are demanding a higher factor to combat recent inflation spikes.
| Metric | 7th Pay Commission (Actual) | 8th Pay Commission (Projected) |
| Old Minimum Pay | ₹7,000 | ₹18,000 |
| Fitment Factor | 2.57 | 1.92 (Low) to 3.68 (High) |
| New Minimum Pay | ₹18,000 | ₹34,560 to ₹66,240 |
| DA Status | Reset to 0% | Expected Reset to 0% |
Note: A Fitment Factor of 3.68 is the demand from major unions to set the minimum wage at ₹26,000+. However, analysts predict a factor between 1.96 and 2.28 is more fiscally probable for the Government.

5. Why is the 8th Pay Commission Crucial?
The 8th Pay Commission is not just about salary; it’s about Real Income.
While your DA increases every 6 months, it only compensates for inflation. A Pay Commission revision (via the Fitment Factor) is supposed to provide a real increase in standard of living beyond just inflation adjustment.
With the 7th CPC tenure ending in December 2025, the data collected (AICPI-IW) throughout 2024 and 2025 will be the final evidence used to lock in the new Fitment Factor.
Conclusion: Prepare for 2026
Understanding the calculation helps us set realistic expectations. The Fitment Factor isn't a gift; it's a mathematical result of the prices of dal, rice, clothing, and housing over the last decade.
As we move closer to 2026, keep a close watch on the AICPI-IW figures released every month on fitmentfactor.in. If the index spikes, your projected Fitment Factor goes up with it.
