Annual Increment
The yearly step to the next cell of your pay level, roughly a 3% basic-pay rise, granted on a fixed date subject to satisfactory service.
Granted on a fixed date each year subject to satisfactory service, the increment continues to accrue during probation, so pay grows even before confirmation. Each step moves you exactly one cell within your pay level, and because DA and HRA are computed on basic pay, a single increment lifts those allowances along with it.
