What is Basic Salary?
Basic salary is the single most important number on your payslip — not because it's the biggest, but because so many other amounts are calculated from it.
What basic salary is
Basic salary (or basic pay) is the fixed, core part of your salary, before any allowances are added. It's usually the largest single component — commonly around 40-50% of your CTC — and it is fully taxable under both tax regimes.
Why basic matters so much
Basic is the base figure that several other amounts are calculated from, which is why it quietly drives your whole payslip:
- Provident Fund (PF) — both your 12% and your employer's 12% are calculated on basic (plus DA).
- Gratuity — accrues at roughly 4.81% of basic (plus DA).
- HRA exemption — the tax-free limit is 50% of basic for metro cities (40% for non-metro). See how HRA works.
- Dearness Allowance — where applicable, is often set as a percentage of basic.
Higher basic vs lower basic
Because so much is pegged to it, the size of your basic involves a trade-off:
- A higher basic means more PF and gratuity — more long-term savings, but a little less cash in hand each month.
- A lower basic means more take-home now, but a smaller retirement corpus and a lower ceiling on your HRA exemption.

The take-home salary calculator lets you change the basic percentage and watch how PF and your in-hand pay move — or read CTC vs take-home salary for the bigger picture.
Frequently asked questions
How much of my salary should be basic?
There's no single fixed percentage, but employers commonly set basic at around 40-50% of CTC. Employers can't keep it artificially low to reduce PF and gratuity liability — labour rules expect basic (and DA) to be a fair share of total pay.
Is basic salary fully taxable?
Yes. Basic salary is fully taxable under both the old and the new tax regime. Unlike HRA or some allowances, no part of basic is exempt.
Does a higher basic salary mean lower take-home?
Often, yes — in the short term. A higher basic increases your PF contribution (12% of basic) and gratuity accrual, so a little less reaches your bank each month, but more goes into your retirement savings.
