Formula used
Annual gross salary = annual CTC minus employer PF only when employer PF is included in CTC. Monthly in-hand = annual gross/12 minus employee PF, user-entered professional tax, estimated monthly income tax and other monthly deductions. Every result is labelled monthly or annual.
Example calculation
For ₹12,00,000 annual CTC, 50% basic, employer PF included, 12% PF, new regime FY 2026-27, ₹200 monthly professional tax and no other deductions: employer PF is ₹72,000 a year, so gross salary is ₹11,28,000 a year or ₹94,000 a month. Employee PF is ₹6,000 a month and the modelled income tax is ₹0. Monthly take-home is ₹94,000 − ₹6,000 − ₹200 = ₹87,800. This is a worked model example, not a payroll quote.
Important assumptions
The assumptions below describe the Quick calculator and its examples. The additional planner has its own visible method, input limits and assumptions, also included in its downloads.
- Annual CTC is entered in rupees and monthly outputs divide annual values by 12.
- Employer PF is removed from CTC only when the user confirms it is included.
- Employee PF is estimated from the selected basic-pay percentage and employee rate.
- Professional tax is user-entered because it is state-specific.
- Income tax uses the selected financial year and regime; surcharge above ₹50 lakh is excluded from this model.
- Variable pay and employer benefits not entered are not modelled.
Common mistakes to avoid
- Treating CTC/12 as cash gross when CTC includes employer PF or other employer costs.
- Selecting an assessment year as though it were the salary-earning financial year.
- Assuming one professional-tax amount applies nationwide.
- Comparing an annual CTC with a monthly take-home without reconciling units.
- Ignoring variable pay, gratuity, insurance or one-time deductions in the offer letter.
