Find the percentage increase between an old and new salary.
The reverse of the salary hike calculator — starting from two salary figures instead of applying a percentage to one.
Increment %: (New − Old) ÷ Old × 100
Sometimes you know both your old and new salary but not the percentage. This calculator works backwards from the two figures to give the rupee increase and the increment as a percentage of the old salary.
It is useful when an appraisal letter states only the revised CTC, when comparing a new job offer with your current pay, or when an HR team wants to compare increments across employees. A teacher in Kochi whose salary moved from ₹8,50,000 to ₹9,52,000 can see what increment that really is. The calculator answers: by what percentage did my salary increase?
1. Write down the old annual salary O and the new annual salary N.
2. Increase in rupees = N − O.
3. Increment % = (N − O) ÷ O × 100.
4. Always divide by the old salary, since the increment is measured from where you started.
5. If N is smaller than O, the result is negative and shows a pay cut.
6. Use the same basis for both figures, for example CTC to CTC, not CTC to in-hand.
A percentage change compares the change with the starting value. Dividing by the new salary gives a smaller number that answers a different question: what share of the new salary is the increase. For a move from ₹8,50,000 to ₹9,52,000, the increase is ₹1,02,000. Divided by the old salary it is 12%. Divided by the new salary it is about 10.7%. Appraisals and offers always use the first, so the calculator does too.
A 20% cut followed by a 20% increment does not restore the original salary. A salary of ₹10,00,000 cut by 20% becomes ₹8,00,000, and a 20% rise on that gives only ₹9,60,000. To return to ₹10,00,000 you need a 25% increment. This is why comparing percentage changes across different bases can mislead, and why stating the rupee amounts alongside the percentage is helpful.
The increment is only meaningful if both salaries are measured the same way. Comparing an old in-hand figure with a new CTC will exaggerate the increment, since CTC includes employer PF, gratuity and sometimes variable pay. If the new structure includes a performance bonus that the old one did not, compare fixed pay with fixed pay separately. The calculator does the arithmetic; choosing comparable figures is up to you.

How do I know if my increment is good?
Increments vary a lot by industry, role, and how well the company is doing. Comparing your increase to your industry's usual yearly range gives more useful context than one single number.
