Most people glance at a salary slip for exactly one number — net pay — and move on. That's fine when everything's correct, but it means an error in any of the lines feeding into that number can go unnoticed for months. The structure underneath is simple once you know what to look for.
The two sides: earnings and deductions
A salary slip is built around one straightforward equation: Gross Earnings minus Total Deductions equals Net Pay — the amount that actually lands in your account. Everything else on the document is just the breakdown of what makes up each side.
Earnings
- Basic Salary — the core, fixed component of your compensation, and usually the number other things (like PF contributions) are calculated as a percentage of.
- HRA (House Rent Allowance) — a separate allowance specifically for housing, which also happens to be partially tax-exempt if you're paying rent (see our HRA exemption breakdown for exactly how that's calculated).
- Other Allowances — a catch-all for anything else added to gross pay: conveyance, special allowance, bonuses for the period, whatever the specific employer structures separately.
Deductions
- Provident Fund (PF) — a mandatory retirement savings contribution, typically deducted as a percentage of basic salary.
- Professional Tax — a small state-level tax, applicable in some states and not others, usually a modest fixed amount.
- Other Deductions — anything else: loan repayments, insurance premiums, or other employer-specific deductions.
Why it's worth actually checking
The most common real errors aren't in the arithmetic (gross minus deductions is simple subtraction, rarely wrong) — they're in the inputs feeding it. A basic salary that doesn't match your offer letter, an allowance that's missing entirely, a deduction line that's higher than expected without explanation. None of these show up if you only ever look at the final net pay figure; they only show up if you check each line against what you actually expect it to be.
Using the tool
Our Salary Slip Generator produces a payslip with exactly this structure — earnings and deductions laid out side by side, gross earnings and total deductions each totaled separately, and net pay calculated automatically from the two. Useful for a small business issuing its own payslips, or just to see the structure clearly laid out with your own numbers.
