A hefty amount is expected to be paid out as arrears under the 8th Pay Commission. This has sparked much discussion among employees of the Central Government as well as those receiving pensions, regarding what amount of arrears will be eligible for these groups. While the pay revision formula remains to be announced by the Government, estimates range from a few lakhs to more than ₹14 lakh of arrears based on the employee’s pay level, fitment factor and date of implementation.
Arrears will be paid based on the date of implementation
At present, it is anticipated that the 8th Pay Commission will result in salary and pension revisions effective 1st January 2026. However, it is likely that these recommendations will not be put into effect immediately. Hence, should the final approval occur a number of months or even years after this date, an employee will receive arrears for the period from 1st January until such time as the new salary is approved. Therefore, if the revised salary is approved in 2027, employees will receive any difference that existed between the old and new salaries during the period.
An amount for arrears will be determined by the Fitment Factor
The fitment factor is the multiplier to convert current basic salary into revised basic salary. Employee unions and experts have suggested fitment factors which vary from 2.0 through 3.83 with discussion among those in the field centering around the factors of 2.15, 2.57 and 2.86.
A higher fitment factor means:
- Higher revised basic pay
- Bigger monthly salary increase
- Larger arrears payout
As a result, the overall value of final arrears will depend primarily on the Commission’s recommendation regarding the fitment factor and its subsequent approval by government authorities.
Arrears of as high as ₹14 lakh are anticipated based on previous estimations; however, the original information shows a range between ₹5 lakh and upto ₹14 lakh across various employees, with maximum amounts generally being attributed to senior level employees with the highest salary ranges and therefore higher fitment factors.
Some reports indicate that, depending upon the agency’s decision to delay implementation or approve a preferable fitment factor, employees in higher pay ranges may receive lump-sum amounts as high as ₹14–₹15 lakh for lost time.
However, these are not considered official government estimates; they are only projections.

Calculating Arrears
The basic formula for calculating arrears is simple:
Arrears = Monthly Salary Increase × Total number of Delayed Months
For example: If the monthly increase is ₹20,000 and there was an overall delay of 20 months, overall estimated arrears will be ₹4 lakh (to arrive at this number, the actual amount of allowances/other adjustments must still be added).
In addition, other yet to be determined adjustments to be included as arrears may include adjustments to House Rent Allowance (HRA), Transport Allowance (TA), and other benefits.
What Employees in Organisations Are Demanding?
Multiple employee organizations have submitted applications to the 8th Pay Commission, asking the Commission to revise their pay to include a higher pay adjustment rate, or “fitment factor,” and to include improved pension benefits. Some organizations have requested that the fitment factor be set at 3.25 while others are requesting that it be set as high as 3.83.
Should the 8th Pay Commission accept all of these requests or even some of them, there may be substantial increases in the amount of arrears due to employees since the updated pay and new arrears would likely be much larger than projected.
No Official Number Released by Government
The government has not yet provided an official amount for the total amount of arrears due to the 8th Pay Commission. The Commission is continuing to conduct consultations with employee and pensioner groups and is collecting input from stakeholders throughout the country. As a result, the deadline for stakeholders submitting their input has been extended, indicating that the Commission is continuing to receive input.
Experts caution against believing what they read on social media regarding fixed total amounts due to employees based on fixed salary levels because, at this point, there is no definitive amount for the total amount of arrears.
What Comes Next?
The 8th Pay Commission is currently working with the employee and pension groups, as well as with other stakeholders in its consultations. Once the 8th Pay Commission provides the government with its report, the government will determine what the total amount that it has approved for the fitment factor, the pay matrix, and when these changes will go into effect.
If the recommendations of the commission are backdated to January 1st, 2026, employees and pensioners will have a right to be paid arrears for this delayed period. Depending on the final calculation of the fitment factor, these amounts may be several lakh rupees or several million dollars for higher level employees.
Conclusion
One of the main attractions for employees under the fifth Central Pay Commission is the potential for receiving a very large arrear payment. Current estimates suggest that employees of the central government could receive anywhere between $5,000 and over $14,000 as arrears; however, the ultimate amount will depend on three major factors, namely; the fitment factor that affects their salary level, the delay in implementing the new system and the number of employees receiving those pensions. Until the Commission makes its recommendations and those recommendations are formally approved by the government, any amounts suggested above are only estimates and not guaranteed payments.
