Model a revised basic using a fitment factor you choose, then add HRA and DA. The 8th CPC has not notified a final fitment — treat every result as a scenario.
01
Enter current basic
Use 7th CPC basic or your last drawn basic.
02
Set fitment
Until an official factor is notified, try the figure your department is modelling.
03
Add HRA and DA
Pick a city class for HRA and an optional DA percentage on the new basic.
