How to Calculate a Salary Hike Percentage (and What It Means for In-Hand Pay)
The hike formulas, what 5–30% hikes on ₹12 lakh do to monthly in-hand pay, your real raise after inflation, and how to compare offers.

Appraisal letters and job offers talk in percentages: "a 12% hike", "a 30% jump". To judge an offer, you need to turn that into rupees, compare it with inflation, and check what actually reaches your bank account each month. Here's how.
The two formulas
Hike % = (new salary − old salary) ÷ old salary × 100
New salary = old salary × (1 + hike ÷ 100)
From ₹12,00,000 to ₹13,80,000: (13,80,000 − 12,00,000) ÷ 12,00,000 × 100 = 15%. A 10% hike on ₹12,00,000 gives ₹13,20,000, or ₹10,000 more a month in CTC terms.

What a hike does to your in-hand pay
The CTC rises by the full percentage, but your take-home pay may not, because PF rises with basic and the extra income may be taxed at a higher slab:
| Hike on ₹12 lakh CTC | New CTC | In-hand per month | In-hand rise |
|---|---|---|---|
| Today | ₹12,00,000 | ₹85,387 | – |
| 5% | ₹12,60,000 | ₹89,666 | 5% |
| 10% | ₹13,20,000 | ₹93,946 | 10% |
| 15% | ₹13,80,000 | ₹98,226 | 15% |
| 20% | ₹14,40,000 | ₹98,696 | 15.6% |
| 30% | ₹15,60,000 | ₹1,03,865 | 21.6% |
Under the new regime, taxable income up to ₹12 lakh pays no tax, so hikes up to 15% here pass straight through to in-hand pay. Look at the step from 15% to 20%: the CTC rises by ₹5,000 a month but in-hand pay by only ₹470, because taxable income crosses ₹12 lakh and tax starts. Above that, each extra rupee is taxed at your slab rate.
Your real hike, after inflation
Real hike ≈ (1 + hike) ÷ (1 + inflation) − 1
| Hike | Real hike with 5% inflation |
|---|---|
| 5% | 0% |
| 10% | 4.8% |
| 15% | 9.5% |
| 20% | 14.3% |
| 30% | 23.8% |
A 5% raise with 5% inflation leaves your buying power almost unchanged. Anything below inflation is a pay cut in real terms.

Frequently asked questions
How do I calculate my hike percentage?
Subtract your old salary from the new one, divide by the old salary and multiply by 100. ₹12 lakh to ₹13.8 lakh is a 15% hike.
What is a 10% hike on ₹50,000?
₹5,000, making the new salary ₹55,000.
Is a hike calculated on CTC or in-hand salary?
Usually on CTC. Your in-hand pay may rise by a slightly different percentage because of PF and tax.
What is a good hike when switching jobs?
Job switches in India often bring 20–40%, depending on the role and industry. Compare the fixed in-hand pay of both jobs, not just CTC.
