You get an offer letter that says ₹12,00,000 CTC. You do the mental math: that's ₹1,00,000 a month. Then the first salary hits your account and it's ₹72,000. Nothing went wrong. This gap between the big number on paper and the money you can actually spend is the single most misunderstood thing about Indian salaries, and it catches even experienced professionals off guard when they switch jobs.
Let's break down exactly where the difference goes, item by item, so the next offer letter you read tells you what you'll really earn.
What CTC actually means
CTC stands for Cost to Company. It is the total amount your employer spends on you in a year, not the amount they pay you. That distinction is everything. CTC includes money that never touches your bank account, money the company sets aside on your behalf, and money that gets deducted before your salary is credited.
A typical CTC has three layers. First, your gross salary, which is basic pay plus allowances like HRA, special allowance, and any bonus. Second, employer contributions that are counted as your cost but paid into funds, not to you. Third, the deductions that come out of your gross before it lands in your account. Only after peeling away layers two and three do you get your in-hand, or take-home, salary.
The deductions that shrink your CTC
Here is each piece that separates CTC from what you keep.
Employer's PF contribution. Under the EPF Act, your employer contributes 12% of your basic salary to your Provident Fund every month. This is part of your CTC, listed as a cost, but you never see it as spendable cash. If your basic is above ₹15,000, many employers cap this at ₹1,800 a month (12% of ₹15,000), though some contribute 12% of the full basic. Either way, it inflates your CTC without adding to your monthly credit.
Gratuity. Companies provision gratuity into your CTC at roughly 4.81% of your basic salary. Gratuity is a lump sum you only receive after completing five years of continuous service, paid using the formula (basic × years × 15) ÷ 26. So this chunk of your CTC is money you cannot touch unless you stay half a decade, and you lose it entirely if you leave before five years.
Employee's PF contribution. Now the deductions from your side. You also contribute 12% of your basic to PF. This comes out of your gross salary, reducing your take-home. It is genuinely your money and it grows tax-free, but it is locked away until retirement (with limited early withdrawal). Between the employer's and your own contribution, PF alone can take a meaningful bite out of a basic-heavy salary structure.
Professional tax. A small state-level tax deducted monthly. It is capped at ₹2,500 per year total, so at most it costs you around ₹200 a month. States like Maharashtra, Karnataka, West Bengal, and Tamil Nadu levy it; some states like Delhi and Haryana do not charge it at all. Minor, but it is a real deduction.
Income tax (TDS). Usually the biggest deduction for higher earners. Your employer deducts tax at source every month based on your projected annual income and your chosen tax regime. Under the new regime, income up to ₹7,00,000 is effectively tax-free thanks to the rebate, and salaried people get a standard deduction. Above that, slab rates apply. The old regime lets you claim deductions like 80C, HRA exemption, and home loan interest, but has higher slab rates. Which regime saves you more depends entirely on your investments and rent, so it is worth checking both.
Putting it together with a real example
Take a ₹12,00,000 CTC. Suppose the structure is: basic ₹6,00,000, HRA and allowances ₹4,50,000, employer PF ₹72,000, and gratuity provision ₹28,800. That employer PF and gratuity (about ₹1,00,800) is CTC but not gross salary, so your gross is roughly ₹10,99,200 a year, or about ₹91,600 a month.
From that gross, subtract your own PF (₹6,000 a month), professional tax (₹200), and monthly TDS (say ₹8,000 depending on regime and declarations). Your in-hand lands somewhere around ₹77,000, not the ₹1,00,000 the CTC implied. The exact figure moves with your salary structure and tax choices, which is why estimating it precisely matters before you sign.
How to estimate your take-home before you accept
Never evaluate an offer on CTC alone. Ask HR for the detailed salary structure, or salary breakup, showing basic, allowances, and each employer contribution separately. Two offers with identical CTC can produce very different take-home pay depending on how much is loaded into non-cash components like PF, gratuity, and variable bonus.
The fastest way to see your real monthly figure is to run the numbers through a take-home salary calculator, which applies PF, professional tax, and current income tax slabs to convert any CTC into an in-hand estimate. Plug in the structure from your offer, compare the old and new tax regimes, and you will know what actually hits your account.
None of these deductions are the company cheating you. PF and gratuity build your long-term savings, and tax is unavoidable. But knowing the split turns a confusing offer letter into a clear decision. When you can look at a CTC and immediately picture the take-home behind it, you negotiate better and you are never surprised on payday.
