Central government employees should track three main things to understand their potential arrears.
1. Your current basic pay.
2. The final fitment factor of the 8th Pay Commission.
3. The exact rollout date of the new salary.
Let us say your new basic pay goes up by Rs 20,000 and the government delays the rollout by 20 months. You will see a difference of Rs 4 lakh just in the basic pay. The final amount will also include DA and other allowances. You should treat figures like Rs 8 lakh, Rs 13 lakh, or Rs 17.94 lakh as rough estimates for now, since the commission has not finalised the new pay structure yet.
