Salary & compensation · Updated September 2026
Basic salary is the fixed core of your pay, before any allowances are added. It looks like just one line on a payslip, but it is the figure almost everything else is calculated from, which makes it the most important number in a salary structure and the one worth checking first.
Basic is usually set at 40% to 50% of CTC. A structure with a deliberately low basic increases short-term take-home because less goes to PF, but it also shrinks your retirement corpus, your gratuity and your HRA exemption. Two offers with identical CTC but different basic are not worth the same over a career.
The Code on Wages, 2019 defines “wages” so that allowances excluded from it cannot exceed 50% of total remuneration. In effect, basic plus DA must be at least half of pay. When the Code is fully notified, employers running very low-basic structures will have to rebalance, which raises PF and gratuity costs for both sides.
Worse for immediate take-home, better for retirement savings, gratuity and, if you rent, HRA exemption. For most people a basic around 45 to 50% is a reasonable balance.
Reducing basic is legally fraught and generally not done for existing employees. Restructuring usually happens at increment time by growing other components more slowly.
They are separate lines, but for PF, gratuity and HRA they are almost always taken together as “basic plus DA”.
