A line-by-line walk from the number on your offer letter to the amount that lands in your bank account every month.
Cost to company adds together everything the employer spends on you: basic, HRA, special allowance, the employer's 12% PF contribution, a gratuity provision (4.81% of basic), and often group insurance, meal cards or variable pay. Only part of that is paid monthly.
Gross = CTC − Employer PF − Gratuity − other employer-only costs
Employer PF is 12% of basic. Many employers cap it at 12% of ₹15,000 (₹1,800 a month), the statutory wage ceiling; others pay 12% of full basic.
Basic 50% = ₹6,00,000. Employer PF (capped) ₹21,600; gratuity 4.81% = ₹28,860. Gross = ₹11,49,540. Taxable under the new regime = ₹10,74,540, which is below ₹12 lakh, so income tax is nil. In-hand = ₹11,49,540 − ₹21,600 PF − ₹2,400 PT = ₹11,25,540 a year, about ₹93,800 a month — 94% of CTC.
Ask for the salary structure, not just the CTC. Check whether variable pay is guaranteed, whether PF is on full basic, and whether insurance is included. Two offers with the same CTC can differ by several thousand rupees a month in take-home.
