How to calculate a 30% hike on CTC, and what it means for in-hand salary

CTC (cost to company) is the total your employer spends on you in a year. It includes your salary, the employer's PF contribution, gratuity and any bonus. A 30% hike on CTC is worked out on this total, not on your monthly take-home.

New CTC = Current CTC × 1.30

1. Take your current yearly CTC, for example ₹10 lakh.
2. Multiply it by 1.30. The new CTC is ₹13,00,000.
3. The hike in rupees is the new CTC minus the old one: ₹3 lakh a year.
4. To see the change in your monthly bank credit, work out in-hand pay on both CTCs. That step needs PF, professional tax and income tax, which is where the 30% shrinks or grows.

The same steps work for any hike. For other percentages, the reverse calculation and common mistakes, see how to calculate salary hike percentage.

The table applies a 30% hike to five CTCs. Every row uses the same structure: basic pay at 50% of CTC, HRA at 50% of basic, PF of 12% on the ₹25,000 monthly wage ceiling, gratuity inside the CTC, professional tax of ₹2,500 a year, no variable pay and the new tax regime. The figures are illustrations; your offer letter may use a different structure.

• At ₹6 lakh and ₹10 lakh, in-hand pay rises more than 30%: 34.4% and 32.5%. The new CTC still pays no income tax, and PF and professional tax stay the same.
• At ₹15 lakh the in-hand rise falls to 27.7%, with ₹78,501 more tax a year.
• At ₹25 lakh and ₹40 lakh most of the hike is taxed at 30% plus cess, so in-hand rises 24.5% and 26.1%.

In-hand pay is your gross salary minus your PF, professional tax and income tax. When CTC rises 30%, the parts that grow with salary decide what you keep.

Extra in-hand = Extra CTC − extra employer PF and gratuity − extra employee PF − extra income tax

• Income tax grows faster than salary. India taxes income in slabs. In the new regime the rates are 5%, 10%, 15%, 20%, 25% and 30% as income rises, plus 4% health and education cess. A hike is taxed at your top slab, so the share lost to tax is higher than your average tax rate.
• PF on the wage ceiling stays flat. From 17 September 2026 the EPF wage ceiling is ₹25,000 a month. When PF is on the ceiling, both your PF and the employer's stay at ₹3,000 a month after the hike, so they do not reduce the extra pay.
• Gratuity grows with basic. Many employers show gratuity of 4.81% of basic inside the CTC. Since basic rises with the hike, a small part of the extra CTC goes to gratuity, which you receive only when you leave after the qualifying service.

So on a ₹12 lakh CTC, a 30% hike to ₹15,60,000 adds ₹21,329 a month to in-hand pay, a rise of 23.3%. The new salary pays ₹95,391 of income tax a year, where the old one paid none. The salary calculator shows the full breakup for any CTC.

In the new regime, the rebate makes tax zero when taxable income is up to ₹12 lakh. For salaried people the ₹75,000 standard deduction comes off first, so gross salary up to ₹12.75 lakh pays no tax. Just above the line, marginal relief applies: the tax cannot be more than the income above ₹12 lakh. In practice, almost every extra rupee in that band goes to tax until the normal slab tax catches up.

This creates a flat zone. In the structure used here, a ₹13.4 lakh CTC still pays ₹0 of tax and gives ₹1,02,773 a month in hand, while a ₹14 lakh CTC gives ₹1,02,857. The table shows different hikes on a ₹10 lakh CTC.

A 40% hike on ₹10 lakh leaves you with ₹27,736 more a month, slightly less than the ₹27,899 from a 35% hike. The extra ₹50,000 of CTC goes almost fully to tax. The exact band moves with your basic share, PF basis and whether you use the old regime, so check your own numbers. The guide is income up to ₹12 lakh tax-free? explains the rebate in detail.

A "30% hike" in an offer letter often includes money that is not paid every month or every year. Take a current fixed CTC of ₹12 lakh and an offer of ₹15.6 lakh.

• Variable pay. If ₹2 lakh of the ₹15.6 lakh is a performance bonus, the fixed part is ₹13.6 lakh. Your fixed pay rises only 13.3%. The bonus is paid later, often once a year, and only if targets are met.
• Joining bonus. If ₹1.5 lakh is a one-time joining bonus, the pay that repeats every year is ₹14.1 lakh, a 17.5% hike. In the second year, CTC drops by the bonus amount.
• Clawback clauses. Many joining bonuses must be paid back if you leave within a set period, often 12 months. Read the clause before counting the bonus as yours.
• Your old CTC. If your current CTC also has variable pay, compare fixed with fixed. If you did not receive the full bonus last year, the CTC on paper overstates what you were paid.

Two offers with the same CTC can be very different. These are the facts that decide how much of a CTC reaches you.

• Monthly pay comes from fixed pay. Variable pay is not part of the monthly salary credit.
• Future hikes compound on the base. Next year's appraisal is usually a percentage of fixed pay or CTC. A 10% hike on a fixed ₹15.6 lakh gives ₹17,16,000, while the same 10% on a fixed ₹13.6 lakh gives ₹14,96,000.
• Basic decides PF and gratuity. Basic is usually a share of fixed pay. Gratuity is based on basic, and PF too when it is on the full basic. A higher basic means more long-term savings but can mean less in-hand.
• Employer PF and gratuity inside the CTC. In most private jobs they are counted in the CTC. If one offer pays them on top of the CTC, the two headline CTCs are not equal.
• Tax is the same on both. Variable pay and joining bonuses are taxed as salary in the year they are paid, at your slab rate.
