To calculate your salary hike percentage, subtract your old CTC from the new one, divide by the old CTC, and multiply by 100. A rise from ₹6,00,000 to ₹7,20,000 is an increase of ₹1,20,000, which is a 20% hike. To go the other way, multiply your current CTC by one plus the hike as a decimal — a 15% hike on ₹8,00,000 gives ₹9,20,000.
Salary Hike Formula
New CTC = Old CTC × (1 + Hike % ÷ 100)
CTC after n years = Current CTC × (1 + Hike % ÷ 100)n
Worked example. A CTC of ₹6,00,000 rising to ₹7,20,000 is an increase of ₹1,20,000. Divided by the old CTC that is 0.20, so the hike is 20%. Going the other way, a 15% hike on ₹8,00,000 gives ₹8,00,000 × 1.15 = ₹9,20,000.
Using the calculators above
- Hike percentage — enter your current and new CTC to get the increment as a percentage.
- New CTC — enter your current CTC and an expected hike to see what you would land on.
- Percentage — apply any percentage to any amount, for the parts of an offer quoted separately.
Annual or monthly figures both work, as long as you use the same basis in both boxes. A monthly figure in one and an annual figure in the other will give you a nonsense percentage — this is the single most common mistake with hike calculations.
The formula in Excel or Google Sheets
If you are modelling several offers, the same calculation as a spreadsheet formula:
- Hike percentage — with the old CTC in A2 and the new in B2:
=(B2-A2)/A2, then format the cell as a percentage. - New CTC from a hike — with CTC in A2 and hike percent in B2:
=A2*(1+B2/100) - CTC after several years — with the annual hike in B2 and years in C2:
=A2*(1+B2/100)^C2
What a hike compounds to over 5 and 10 years
A single increment is easy to judge. What it is worth repeated is much less intuitive, because salary compounds the same way an investment does — each year’s rise is calculated on the raised base.
Starting from a CTC of ₹10,00,000:
| Annual hike | After 5 years | After 10 years | 10-year multiple |
|---|---|---|---|
| 5% | ₹12.76 L | ₹16.29 L | 1.63× |
| 8% | ₹14.69 L | ₹21.59 L | 2.16× |
| 10% | ₹16.11 L | ₹25.94 L | 2.59× |
| 12% | ₹17.62 L | ₹31.06 L | 3.11× |
| 15% | ₹20.11 L | ₹40.46 L | 4.05× |
The gap between 10% and 15% looks like five percentage points. Over a decade it is the difference between ₹25.9 lakh and ₹40.5 lakh — a career’s worth of money.
At a steady 10% a year your salary doubles in about 7.3 years. At 15% it doubles in 5. This is the argument for treating a below-average increment as a compounding problem rather than a one-year disappointment, and it is why a single well-timed move that resets your base can outweigh several years of routine appraisals.
Why a 20% hike does not put 20% more in your account
CTC is what you cost your employer. In-hand is what reaches your bank. The gap between them is wide, and it does not scale evenly — which is why an increment so often disappoints when the first payslip arrives.
- Employer PF contribution counts inside CTC but never reaches your account. Because it is derived from basic pay, a hike that raises basic sends part of your increment straight into your provident fund.
- Gratuity provision is often included in CTC too, and you see it only after five years of service.
- Tax moves in steps. If the increment crosses a slab boundary, the portion above it is taxed at the higher rate — so the marginal gain is smaller than the average.
- Variable pay may be a larger share of the new CTC than the old. A 20% hike where variable doubles is not a 20% guaranteed increase.
- Stated-value benefits — insurance, meal cards, transport — inflate CTC without inflating cash.
When comparing two offers, compare the fixed component, not the CTC. Two offers with identical CTC can differ by lakhs in annual take-home depending on how each is structured.
Ask which component is changing
Two increments of the same percentage can have very different effects depending on where the money is placed.
A hike delivered through basic pay raises your PF contribution, your gratuity accrual and your HRA entitlement, since all three are calculated from basic. More goes into long-term savings, and less arrives as monthly cash — but the total value to you is higher.
A hike delivered through allowances or special pay arrives more fully as cash and is often more heavily taxed, with no effect on your PF or gratuity.
Neither is universally better. But an appraisal letter that quotes only the CTC change tells you nothing about which one you got, and it is a fair question to ask.
What counts as a good hike
There is no benchmark percentage, and figures quoted in the press are averages across industries that behave nothing like each other. Three tests are more useful.
Does it beat inflation? An increment below the inflation rate is a real-terms pay cut, whatever the number looks like. This is the first test, and a surprising number of increments fail it.
Does it move you toward the market rate? A strong percentage on a low base can still leave you underpaid. A weak percentage on a base that is already above market may be fine.
What does it do to your base? Because increments compound, the base you carry into next year matters more than this year’s cash. That is the reasoning behind the table above.
