CalcKitA job offer of ₹12,00,000 a year sounds like ₹1,00,000 a month — until the first payslip arrives and the number is closer to ₹85,000. Nothing has gone wrong. The offer figure is your CTC, or cost to company: the total amount your employer spends on you, not the salary it pays you. Part of that total never reaches your bank account at all, and several deductions are taken from what remains. Once you know the two layers between CTC and take-home pay, you can work out your real monthly salary from any offer letter in minutes.
CTC, gross salary and in-hand salary are three different numbers
Think of your pay as three stacked layers. CTC is the top layer: everything the company spends on employing you, including its own contributions to your provident fund and its gratuity provision, plus any insurance premiums or other benefits it funds. Gross salary is the middle layer: the salary actually paid to you before your own deductions, made up of basic salary plus allowances such as house rent allowance (HRA) and special allowance. In-hand salary is the bottom layer: gross salary minus your deductions — your own provident fund contribution, income tax deducted at source (TDS), professional tax where your state levies it, and any other recoveries. The journey from CTC to in-hand pay is a two-step subtraction, and skipping either step is why most estimates come out too high.
The formula
Step 1: Gross salary = CTC − employer contributions. Employer contributions are the employer's provident fund contribution and its gratuity provision, which sit inside CTC but are not paid to you as monthly salary. Step 2: In-hand salary (annual) = gross salary − employee deductions. Employee deductions are your own provident fund contribution, income tax (TDS), professional tax where applicable, and any other deductions. Step 3: Monthly in-hand salary = annual in-hand salary ÷ 12. That is the whole calculation; your offer letter and payslip usually spell out each component.
Worked example: a ₹12,00,000 CTC
Take an offer with a CTC of ₹12,00,000 a year. Suppose the breakup is: basic salary ₹4,80,000, HRA ₹1,92,000, and other allowances ₹4,47,300, giving a gross salary of ₹11,19,300. The remaining ₹80,700 of the CTC is employer-side: an employer provident fund contribution of ₹57,600 and a gratuity provision of ₹23,100. Those two amounts are real costs to the employer, but they are not monthly pay — the provident fund contribution goes into your retirement fund and the gratuity provision is set aside for your end-of-service payout.
Now subtract the employee deductions from the gross salary of ₹11,19,300. Say the employee provident fund contribution is ₹57,600, professional tax is ₹2,400 for the year, and income tax deducted at source is ₹45,000 for the year in this example — actual tax depends on your income, your chosen tax regime and current slabs, so check current rates rather than treating this figure as a rule. Total deductions come to ₹1,05,000. Annual in-hand salary is therefore ₹11,19,300 − ₹1,05,000 = ₹10,14,300, and monthly in-hand salary is ₹10,14,300 ÷ 12 = ₹84,525. A ₹12,00,000 CTC becomes ₹84,525 a month in hand — about 15% less than the ₹1,00,000 a month the headline figure suggests. Try your own numbers in our free Salary / Tax Calculator.
The deductions, one by one
The provident fund is usually the biggest deduction after tax. Both you and your employer contribute, and both contributions are calculated on basic salary, which is why a higher basic component means a bigger provident fund balance but a smaller monthly take-home. Income tax is deducted at source each month based on your estimated annual income and the tax regime you choose; it is an advance payment of your final tax bill, adjusted when you file your return. Professional tax applies only in some states, while other deductions — insurance premiums, meal or transport recoveries, and loan repayments — depend on your employer's policies and your own choices.
Why two people with the same CTC take home different pay
Two employees can hold identical CTC figures and still receive different monthly salaries, because the breakup matters more than the total. A salary weighted toward basic pay carries higher provident fund deductions; one weighted toward allowances can leave more in hand each month but builds a smaller retirement fund and a smaller gratuity. Tax regime choice, HRA exemption claims, and deductions for investments or insurance also shift the final number. This is why comparing offers by CTC alone misleads: a lower CTC with a cleaner breakup can beat a higher CTC loaded with employer-side costs. Always ask for the full salary breakup, run it through the formula above, and compare the monthly in-hand figures.
Mistakes to avoid
The most common mistake is dividing CTC by 12 and budgeting on the result — that overstates monthly income by the employer contributions and all deductions combined. Another is forgetting variable pay: if part of your CTC is a performance bonus paid once a year, your regular monthly salary is lower than the CTC ÷ 12 figure suggests. A third is treating the first payslip as the final answer: tax deductions are often estimated at the start of the year and corrected later, so monthly take-home can shift during the year. Work out the in-hand figure from the breakup and revisit it whenever your salary structure or the tax rules change.
