What is a fitment factor?
The fitment factor is the single multiplier a Pay Commission applies to an employee's existing basic pay to arrive at the revised basic pay. It exists to convert the old pay structure — including the dearness allowance that has accumulated since the last revision — into one clean starting figure in the new pay matrix. The formula is simply:
Revised basic pay = Existing basic pay × Fitment factor
Current fitment factor vs previous fitment factor
- 6th Pay Commission (2006): 1.86x — the previous fitment factor.
- 7th Pay Commission (2016): 2.57x — the current fitment factor in force.
- 8th Pay Commission (expected 2026–27): estimates between 1.92x and 2.86x, with 2.28x the most widely reported figure. Nothing has been officially notified yet.
How the factor is derived
A Pay Commission adds the DA neutralisation percentage on the implementation date to 100%, then adds a real increase. For the 7th CPC, DA stood at 125%, so 2.25 plus a 14.29% real rise produced 2.57x. If DA reaches roughly 60–70% by January 2026, a similar approach gives a factor in the 1.92x–2.28x band; a more generous real increase would push it towards 2.86x.
Fitment factor vs fitment allowance
The two terms are often mixed up. The fitment factor is a multiplier on basic pay. A fitment allowance, used in some state revisions and PSU settlements, is a flat amount or percentage merged into basic pay instead of a multiplier. Both aim to absorb accumulated DA, but only the factor scales proportionally across all pay levels.
Why the factor matters more than any allowance
Because DA, HRA, transport allowance, pension and gratuity are all computed as a percentage of basic pay, a change of even 0.1x in the fitment factor compounds across the entire salary and post-retirement benefits. That is why every 0.29x step in the table above — 2.28x to 2.57x, and 2.57x to 2.86x — produces such a visible jump in the projected figures.
