8th Pay Commission DA Reset — Why Your 60% DA Goes to 0%

Dearness Allowance exists to compensate employees for inflation. It is calculated as a percentage of basic pay and revised every six months based on the All India Consumer Price Index (AICPI). Over the course of a Pay Commission's tenure (typically 10 years), DA accumulates significantly — reaching 125% by the time of 7th CPC implementation, and 60% now.

When a new Pay Commission revises the pay matrix, it absorbs the existing DA into the new basic pay through the fitment factor. The fitment factor is not an arbitrary number — it is calibrated to compensate for: (a) accumulated inflation since the last revision, (b) the existing DA component, and (c) a real-terms increase in purchasing power.

This is why a 2.57× fitment factor was used in the 7th CPC — because DA at that time (125%) plus real pay increase justified that multiplier. The 8th CPC fitment factor will similarly embed the current 60% DA.

HRA rates are linked to DA thresholds. On Day-1 of 8th CPC implementation, your DA will be 0%. This means you will initially receive the lowest HRA rate:

• X-class cities: 24% of new basic (not 30%)
• Y-class cities: 16% of new basic (not 20%)
• Z-class cities: 8% of new basic (not 10%)

Once DA crosses 25% (estimated 2–3 years after implementation), HRA steps up. Once DA crosses 50%, it reaches the final rate. Our calculator shows the long-term steady-state HRA by default, with the Day-1 amount separately displayed as a note.

This is why some employees will see a temporary dip in take-home pay in the first 2 years of 8th CPC, even with a higher basic pay.
