Appraisal season is where HR and finance talk past each other every year. HR sees the employee’s take-home bump. Finance sees the cash going out the door. They are not the same number, and the gap catches people out. This calculator shows both sides at once so a raise gets sized against a budget instead of eyeballed.
Two numbers, one raise
A ₹12 lakh employee on a 10% hike moves to ₹13.2 lakh. Their monthly in-hand rises about ₹8,560. That is the number the employee cares about and the one HR quotes in the appraisal conversation.
The company’s cost is different. The full ₹1.2 lakh of extra CTC leaves the business, not the ₹8,560-a-month slice the employee feels. The rest goes into employer PF, gratuity provision and the tax the employee pays on the raise. Add a one-time retention bonus of ₹50,000 on top and year-one outflow climbs to ₹1.7 lakh for that single hike. The employee experiences a ₹1 lakh-a-year in-hand bump; the company writes off ₹1.7 lakh. Both are true.
Why the take-home gain lags the headline hike
A 10% CTC hike almost never means 10% more in the bank. The raise is taxed at the employee’s marginal rate, and once someone crosses into the 30% slab, roughly a third of every extra rupee is gone before it reaches them. Professional tax and the employee PF on any basic increase take a further nibble.
This is exactly why restructuring beats a flat raise at higher salary bands. Above ₹25 lakh or so, diverting part of an increment into employer NPS under 80CCD(2) can hand the employee more net benefit than the same money paid as taxable salary, at no extra cost to the company. The calculator here models the straight hike; to see how the restructured version plays out, run the new CTC through the in-hand salary optimizer.
Sizing the retention bonus
The retention bonus field is where you stress-test a counter-offer. A departing employee with a competing offer usually needs both a hike and a lump sum to stay. Model the combined year-one cost before you commit, because a ₹2 lakh golden handcuff on top of a 15% raise adds up faster than most managers estimate in the moment.
For the percentage side of the decision, the salary hike calculator checks an increment against typical market bands. To confirm the exact monthly in-hand before and after on the full salary structure, use the take-home salary calculator.
