8th Pay Commission: At Fitment Factor 2.57, 12-Months Arrears To Be Rs 5.15 Lakh At Rs 44,900 Basic Pay; How?

The 8th Pay Commission has marked its 12 months, and there are six more months left for the Justice Ranjana Prakash Desai-led commission to submit their final report for implementation of the next pay commission. Under its terms of reference (ToR), Desai's committee were given 18 months to submit final recommendations. The time is ticking, and anticipation has heightened for the 8th CPC, which is going to benefit 1.17 crore central government employees and pensioners.

If the revised pay structure under the 8th CPC is implemented from January 1, 2026, central government employees and pensioners hope for significant lump-sum arrears. The 7th Pay Commission has ended as of December 31, 2026.

However, a lot will depend upon the fitment factor, which is crucial in calculating the scope of hikes in basic pay and pensions from 7th CPC. There are many recommendations for fitment factor. Some are modest at 1.90, and some recommendations are extraordinarily eye-popping, like the 4 fitment factor.

Fitment factor	Category	Status
1.92	Conservative estimate	Expert estimate
2.00-2.10	Conservative estimate	Expert estimate
2.28	Moderate estimate	Projection
2.57	7th CPC factor	Reference point
2.86	Higher estimate	Reported proposal
3.00	Higher estimate	Employee organisation demand
3.25	Higher estimate	Employee organisation demand
3.61	Union proposal	Demand
3.833	NC-JCM and other organisations	Formal demand
4.00	BPMS	Formal demand

Nonetheless, let's assume the 8th Pay Commission committee settles for a 2.57 fitment factor, the same as the 7th Pay Commission.

At a 2.57 fitment factor, level 7 grade employees with Rs 44,900 basic pay could attract between Rs 5.06 lakh to Rs 5.14 lakh in arrears for the 12 months. Let's calculate:

Basic Pay under the 7th Pay Commission x the new Fitment Factor of 2.57 under 8th Pay Commission:

Rs 44,900 x 2.57 = Rs 1,15,393.

Arrears Calculation Formula is = (New Salary - Old Salary) × Months Due

The arrears calculation also includes dearness allowance (DA) component. The difference between the new salary under 8th CPC and old salary of 7th CPC would fall at Rs 70,493.

For January to June 2026, the DA was at 60% and then hiked to 63% from July to December 2026. Let's apply that as well.

Let's do the detail calculation:

Revised Basic Pay = Rs 1,15,393
Old Basic Pay = Rs 44,900
January - June 2026 DA = 60%
July - December 2026 DA = 63%

For, January to June - DA at 60%, the monthly difference in the salary will be Rs 43,553 per month. For July to December - DA at 63%, the difference will come around Rs 42,206 per month.

Arrears for January to March 2026 = Rs 43,553 x 6 months = Rs 2,61,318

Arrears for July - December 2026 = Rs 42,206 x 6 months = Rs 2,53,236.

Arrears for entire 12 months (January - December 2026) would come around Rs 5,14,554 for the employee.

1. Calculate revised 8th CPC basic pay
₹44,900 \times 2.57 = ₹1,15,393
So, hypothetical revised basic pay = ₹1,15,393.
2. January to June - DA at 60%
Particulars	Amount
Existing basic pay	₹44,900
DA at 60%	₹26,940
Existing basic + DA	₹71,840
Revised 8th CPC basic	₹1,15,393
Monthly difference	₹43,553
Six-month arrears: ₹43,553 \times 6 = ₹2,61,318
3. July to December - DA at 63%
Particulars	Amount
Existing basic pay	₹44,900
DA at 63%	₹28,287
Existing basic + DA	₹73,187
Revised 8th CPC basic	₹1,15,393
Monthly difference	₹42,206
Six-month arrears: ₹42,206 \times 6 = ₹2,53,236
4. Total 12-month arrears
Period	Monthly difference	Months	Total
January-June (60% DA)	₹43,553	6	₹2,61,318
July-December (63% DA)	₹42,206	6	₹2,53,236
Total		12	₹5,14,554

8th Pay Commission Pay Matrix

By applying the same formula to all level grades of employees, here's how much arrears they could be eligible to receive.

Level 1: At 2.57 fitment factor for the 8th CPC, their basic pay would rise to Rs 46,260 from Rs 18,000 per month, and they could be eligible for arrears up to Rs 2,06,280 from the January to December 2026 period.

Level 5: These grade employees' salaries could rise from Rs 29,200 to Rs 75,044 per month. Arrears would come around Rs 3,34,632.

Level 10: They salary would nearly triple to Rs 1,44,177 at fitment factor of 2.57 from old basic pay of Rs 56,100. They also become eligible to receive arears of up to Rs 6,42,906.

Level 15: At 2.57 fitment, level 15 employees salary could rise to a whopping Rs 4,68,254 from current Rs 1,82,200 under 8th Pay, while they would be eligible for Rs 20,88,012 arears.

Level 18: The highest grad employees are of level 18 and at 2.57 fitment factor their salary could rise to an impressive Rs 6,42,500 from Rs 2.50 lakh per month. Taking into consideration the above formula, they would be looking at arrears up to Rs 28,65,000.

These are just examples and illustrations, and they are not the official announcement. The government is yet to take a decision on the 8th Pay Commission, including fitment factor, salary hike, allowances, and other benefits.
