8th CPC Arrears Calculator
The 8th CPC arrears calculator estimates the lump-sum payment you will receive if the 8th Pay Commission is implemented with a notional date of 1 January 2026 but actual cash payment starts months later. Arrears are the difference between your old salary and new salary for each month of delay.
How arrears are calculated
Arrears = (New monthly in-hand salary - Old monthly in-hand salary) x Number of months of delay
For example, if the 8th CPC is implemented with notional effect from January 2026 but cash payment starts in July 2026 (6 months delay), and your new in-hand is Rs 5,000/month higher than your old in-hand, your arrears would be Rs 30,000 (Rs 5,000 x 6 months).
Arrears estimate by pay level
| Level | Old In-Hand | New In-Hand (1.92x) | Monthly Diff | 6-Month Arrears | 12-Month Arrears |
|---|---|---|---|---|---|
| Level 1 | Rs 38,940 | Rs 41,560 | Rs 2,620 | Rs 15,720 | Rs 31,440 |
| Level 6 | Rs 73,560 | Rs 78,920 | Rs 5,360 | Rs 32,160 | Rs 64,320 |
| Level 10 | Rs 1,11,420 | Rs 1,19,800 | Rs 8,380 | Rs 50,280 | Rs 1,00,560 |
| Level 13 | Rs 2,25,300 | Rs 2,42,100 | Rs 16,800 | Rs 1,00,800 | Rs 2,01,600 |
| Level 18 | Rs 4,50,000 | Rs 4,80,000 | Rs 30,000 | Rs 1,80,000 | Rs 3,60,000 |
Note: These are estimates at 1.92x fitment. Actual arrears depend on the final fitment factor, implementation date, and your specific pay level and allowances.
Tax on arrears
Arrears are taxable in the year you receive them, not the year they relate to. This could push you into a higher tax bracket. However, you can claim tax relief under Section 89(1) of the Income Tax Act, which allows you to spread the arrears across the years they relate to, reducing your tax burden.
To claim Section 89(1) relief:
- Calculate tax on your total income (including arrears) for the current year.
- Calculate tax on your total income (excluding arrears) for the current year.
- Calculate tax on your total income (including arrears) for each previous year the arrears relate to.
- The relief is the difference between the tax in step 1 and the sum of taxes in steps 2 and 3.
- File Form 10E with your employer or in your income tax return.
When will arrears be paid?
Based on the 7th CPC timeline:
- Cabinet approval: January 2025
- Commission report: Expected 2026-2027
- Government notification: After report acceptance
- Implementation: Notional from January 2026, cash payment follows
- Arrears payment: Typically within 3-6 months of notification

Arrears estimates are based on expected fitment factors. Actual arrears depend on the official 8th CPC notification, implementation date, and your specific pay and allowances.
Formula
Monthly Arrears = (New In-Hand - Old In-Hand) Total Arrears = Monthly Arrears x Number of Months Delay
Example
Old In-Hand: Rs 86,700 New In-Hand: Rs 110,688 (at 1.92x) Monthly difference: Rs 23,988 If implemented 8 months late: Total Arrears = 23,988 x 8 = Rs 1,91,904
How to Use
- Calculate your old and new in-hand salary
- Note the monthly difference
- Estimate how many months of delay
- Multiply monthly difference by months of delay
