An in hand salary calculator exists because CTC, the number quoted in an offer letter, and the amount that actually lands in a bank account each month are rarely the same figure. The gap comes from a specific, traceable set of deductions and employer-side components, not from anything mysterious. This guide walks through what those components are, how professional tax differs by state, how bonus payouts affect a monthly figure, and how the choice between the old and new tax regime changes the final number.
CTC vs Gross vs Net Salary: What's the Difference
A ctc calculator has to start by separating three terms that get used loosely in everyday conversation but mean specific, different things on an actual payslip. CTC, or cost to company, is the total amount an employer spends on an employee in a year, including money that never becomes cash in the employee's hands. Gross salary is the cash component of that total before any deductions: basic pay, HRA (house rent allowance), and other allowances. Net salary, or in-hand salary, is what's left of gross salary after deductions.
CTC generally includes gross salary plus the employer's provident fund contribution, an accrual toward eventual gratuity, and the cost of benefits like group health insurance where these are bundled into the package. None of these employer-side components show up as a monthly credit in the employee's bank account, which is exactly why CTC divided by 12 tends to overstate monthly in-hand pay.
Net salary is arrived at by taking gross salary and subtracting the employee's own provident fund contribution, professional tax where the state levies one, and income tax deducted at source (TDS), calculated according to the tax regime and slab the employee falls under.
For example, an employee with a CTC of ₹9,00,000 might have a gross salary of ₹7,80,000 once employer PF and a gratuity accrual are set aside, and a net salary of roughly ₹7,00,000 after the employee's own PF contribution, professional tax, and TDS are deducted, though the exact figures depend on that employee's specific salary structure and tax situation.
| Term | What it includes | Shows up in bank account? |
|---|---|---|
| CTC | Gross salary + employer PF + gratuity accrual + other employer-borne benefits | No |
| Gross salary | Basic pay + HRA + other allowances | Before deductions |
| Net (in-hand) salary | Gross salary − employee PF − professional tax − TDS | Yes |
The in-hand salary calculator applies this breakdown to a specific CTC figure, which is generally more reliable than estimating a flat percentage.
What Gets Deducted From CTC to Reach Take-Home
To calculate salary correctly from a CTC figure, it helps to work through the deductions in the order they're actually applied, since CTC first narrows to gross salary, and gross salary then narrows to net salary through a separate set of deductions.
The first deduction, and generally the largest for most salaried employees, is the employee's own provident fund contribution: 12% of basic pay plus dearness allowance, deposited into the Employees' Provident Fund. Both the employee and employer contribute this 12%, but only the employee's share reduces monthly in-hand pay directly; the employer's matching share is an addition to CTC that never touches gross salary in the first place.
Professional tax comes next, where the state an employee works in levies one. It's a small, generally fixed monthly amount, capped at ₹2,500 a year under Article 276(2) of the Constitution of India, and it varies meaningfully by state, covered in more detail in the next section.
The final and usually largest deduction is TDS, income tax withheld from salary under the provisions that were previously in Chapter XVII-B of the Income-tax Act, 1961, and now sit under the Income-tax Act, 2025, which came into force on 1 April 2026 and governs income earned from FY 2026-27 onward. The amount withheld depends on projected annual salary, the tax regime chosen for that year, and any deductions or exemptions declared to the employer, such as HRA exemption or Section 80C investments under the old regime.
An in hand pay calculator that only accounts for PF and ignores professional tax and TDS will overstate take-home pay, sometimes substantially at higher income levels where TDS becomes the dominant deduction. All three deductions have to be applied in sequence to arrive at an accurate net figure, which is what the in-hand salary calculator does automatically for a given CTC and state.
Professional Tax: State-Wise Variation
Professional tax is a state-level levy, not a central one, which is why ctc to in hand salary calculations differ slightly depending on which state an employee works in, even for an identical CTC and salary structure elsewhere.
In Maharashtra, under the Maharashtra State Tax on Professions, Trades, Callings and Employments Act, 1975, salaried men earning above ₹7,500 a month pay ₹200 a month for eleven months and ₹300 in February, reaching the constitutional cap of ₹2,500 a year. Following a 2023 amendment to the Act, women earning up to ₹25,000 a month are exempt from this tax entirely; women earning above that threshold pay the same slab as men.
In Karnataka, under the Karnataka Tax on Professions, Trades, Callings and Employments Act, 1976, as amended with effect from 1 April 2025, employees earning below ₹25,000 a month are exempt, while those at or above that threshold pay ₹200 a month, rising to ₹300 in February, again reaching the ₹2,500 annual cap. Unlike Maharashtra, Karnataka doesn't apply a separate slab by gender.
For example, a salaried man in Mumbai earning ₹30,000 a month falls into Maharashtra's taxable slab and has ₹200 deducted most months, while a woman in the same role and city, earning the same ₹30,000, is exempt entirely since it's below Maharashtra's ₹25,000 women's exemption threshold. The same employee moved to a Karnataka-based role at the same salary would have ₹200 a month deducted regardless of gender, since Karnataka's exemption threshold doesn't distinguish by gender the way Maharashtra's does.
A handful of states, including Delhi and several others, don't levy professional tax at all, in which case this deduction simply doesn't apply regardless of salary. Since the tax is capped at ₹2,500 a year everywhere it does apply, it's a comparatively minor factor in most in-hand salary calculations, but it's still worth confirming for the specific state and gender where relevant.
How Bonus and Variable Pay Affect Monthly In-Hand
A takehome salary calculator generally treats bonus and variable pay separately from the guaranteed monthly components of gross salary, since bonus payouts are typically credited on their own schedule, annually or quarterly, rather than spread evenly across twelve months.
Variable pay tied to individual, team, or company performance is, by its nature, not fixed; the amount actually paid can range from the full target amount down to nothing, depending on how targets are met and on employer policy for a given year. Because of this, a monthly in-hand figure calculated from CTC generally reflects only the fixed, guaranteed components, since including an assumed bonus in a monthly average would overstate what's reliably available to spend each month.
When a bonus is paid, it's still subject to the same categories of deduction as regular salary: any portion attributable to PF-eligible components is deducted accordingly, and TDS is calculated on the bonus at the applicable rate for that pay cycle, generally treating it as part of total annual income for TDS purposes rather than taxing it separately at a flat rate. This means a large bonus paid in a single month can push that month's TDS deduction higher than usual, even though the annual tax liability works out the same either way once the full year's income is accounted for.
For example, an employee with a fixed monthly gross salary that produces a steady in-hand figure most months may see a noticeably smaller net credit in the specific month a large annual bonus is paid and taxed, followed by a return to the regular monthly figure afterward. Reviewing an offer's fixed monthly in-hand separately from any variable component generally gives a more realistic month-to-month expectation than averaging the bonus across the year.
Old vs New Regime Impact on Take-Home Pay
A post tax salary calculator needs to know which regime an employee has chosen, since the old and new tax regimes apply different slab rates, different standard deductions, and different rebate thresholds, all of which change monthly in-hand pay even when CTC is identical.
Under the new tax regime, the default option since it was introduced, the slabs for FY 2026-27 are: nil up to ₹4,00,000, 5% from ₹4,00,000 to ₹8,00,000, 10% from ₹8,00,000 to ₹12,00,000, 15% from ₹12,00,000 to ₹16,00,000, 20% from ₹16,00,000 to ₹20,00,000, 25% from ₹20,00,000 to ₹24,00,000, and 30% above that, with a standard deduction of ₹75,000 for salaried employees and a rebate that brings tax to zero for taxable income up to ₹12,00,000. Under the old regime, the slabs are nil up to ₹2,50,000, 5% from ₹2,50,000 to ₹5,00,000, 20% from ₹5,00,000 to ₹10,00,000, and 30% above that, with a standard deduction of ₹50,000 and a rebate that brings tax to zero for taxable income up to ₹5,00,000. A 4% health and education cess applies to the computed tax under either regime.
For example, taking three CTC levels and assuming, for simplicity, that gross salary works out to roughly 90% of CTC after employer PF and a gratuity accrual are set aside, with no additional deductions claimed beyond the standard deduction:
| CTC | Assumed gross salary | New regime tax (with cess) | Old regime tax (with cess, no other deductions) |
|---|---|---|---|
| ₹6,00,000 | ₹5,40,000 | ₹0 (within rebate) | ₹0 (within rebate) |
| ₹12,00,000 | ₹10,80,000 | ₹0 (within rebate) | ₹1,23,240 |
| ₹20,00,000 | ₹18,00,000 | ₹1,50,800 | ₹3,51,000 |
At ₹6,00,000 CTC, both regimes produce zero tax once the rebate applies, so regime choice makes no difference to in-hand pay at this level. At ₹12,00,000 and ₹20,00,000, the new regime results in noticeably lower tax in this particular example, though this comparison assumes no deductions beyond the standard deduction; an employee under the old regime with a large HRA exemption, home loan interest deduction, or Section 80C investments could see a meaningfully different result, potentially favoring the old regime instead.
Is This Right For You?
This guide covers a general, simplified comparison of take-home pay across CTC levels and tax regimes. It isn't a substitute for professional advice where an employer's TDS calculation is disputed, where income includes unusual components like foreign salary or stock options, where significant old-regime deductions like a home loan or large HRA claim need to be modeled precisely, or where the amounts involved are large enough that a wrong regime choice would be costly. A chartered accountant is better placed to run the exact numbers for a specific salary structure.
Conclusion
CTC, gross salary, and net salary are three different figures, and the gap between them comes from employer-side additions like PF and gratuity accrual on one side, and employee-side deductions like PF, professional tax, and TDS on the other. Professional tax varies by state and, in Maharashtra's case, by gender, though it's capped at ₹2,500 a year wherever it applies. Bonus and variable pay are best tracked separately from guaranteed monthly in-hand, since they're paid on their own schedule and aren't guaranteed. Regime choice, old versus new, can meaningfully change monthly take-home, particularly at higher CTC levels and for employees who do or don't have significant deductions to claim.
To work out the numbers for a specific CTC, state, and regime, use the in-hand salary calculator. The HRA calculator guide and gratuity calculator guide go deeper into two of the components that shape this calculation.
FAQs
Why is my in-hand salary lower than CTC divided by 12?
Because CTC includes components that never reach a bank account, such as the employer's PF contribution and an accrual toward gratuity, and because gross salary itself is further reduced by the employee's own PF contribution, professional tax, and TDS. Dividing CTC by 12 skips all of these, which is why the resulting number is almost always higher than actual monthly in-hand pay.
Does professional tax vary by state?
Yes. Professional tax is levied by individual states under their own legislation, so both the threshold at which it applies and the exact amount differ. Maharashtra and Karnataka, for instance, apply different income thresholds and, in Maharashtra's case, a separate exemption for women, while several other states don't levy professional tax at all. It's capped at ₹2,500 a year everywhere it's charged.
How does choosing old vs new tax regime change my monthly in-hand salary?
The two regimes use different slab rates, standard deductions, and rebate thresholds, so the same CTC can produce different TDS deductions depending on which regime is chosen. At lower income levels the difference can be negligible, but at higher CTC levels, and depending on how many deductions an employee can claim under the old regime, the gap in monthly in-hand pay can become significant.
Is employer PF contribution part of my CTC or separate?
It's part of CTC, not separate from it. The employer's 12% provident fund contribution is one of the components, along with gratuity accrual and other benefits, that gets added to gross salary to arrive at the total CTC figure. It never appears as a deduction on a payslip and never reaches the employee's bank account directly, since it's the employer's own contribution rather than the employee's.
