The 7th Central Pay Commission (CPC) introduced a revolutionary change in the salary structure of Central Government employees by replacing the old Pay Band/Grade Pay system with a simplified Pay Matrix. This online calculator helps you accurately determine your new pay based on the fitment factor (2.57), current Dearness Allowance (DA), and House Rent Allowance (HRA).

Understanding the Components

Your gross salary is composed of several key elements. Here is how they are calculated:

Basic Pay: Your basic pay is determined by your Level in the Pay Matrix. For conversion from 6th CPC, the factor is 2.57.
Dearness Allowance (DA): This is a cost-of-living adjustment. As of recent updates, when DA crosses 50%, certain other allowances (like HRA) are automatically revised.
Transport Allowance (TPTA): This depends on your Pay Level and the city you are posted in (Higher TPTA cities vs. Others).

HRA City Classifications (X, Y, Z)

House Rent Allowance is determined by the population of the city you are posted in. The rates were revised when DA crossed 25% and again when it crossed 50%.

City Category	Population Criteria	HRA Rate (DA > 50%)
X (Tier 1)	50 Lakhs & above	30% of Basic
Y (Tier 2)	5 Lakhs to 50 Lakhs	20% of Basic
Z (Tier 3)	Below 5 Lakhs	10% of Basic
