How is HRA calculated in the 8th Pay Commission?

HRA is calculated by applying the HRA percentage slab (based on city class X/Y/Z) to the salary base. Under the 8th CPC, the base may rise due to revised basic pay using the fitment factor, which can increase the HRA amount.

What is the role of fitment factor in HRA calculation?

The fitment factor helps project the revised basic pay under the new pay commission. Since HRA is a percentage of the salary base, any increase in projected basic pay can increase HRA.

Which city classes are used for HRA slabs?

HRA slabs usually depend on posting location categorized as X, Y, or Z. Each category has a different HRA rate. This calculator lets you select a city class and apply the corresponding percentage.
