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% employee PF, new regime FY 2026-27 and ₹200 monthly professional tax, the model reconciles annual CTC to monthly gross and then subtracts employee-side deductions to estimate take-home.
Important assumptions
- 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.
When this tool is useful
- When you want a fast estimate before making a financial or salary decision.
- When you want to compare different assumptions in seconds.
- When you want to understand the formula behind the result.
