How this calculator works
A percentage increase multiplies a value by one plus the rate. Raising 50,000 by 12% means multiplying by 1.12 — a shortcut worth remembering, because it composes cleanly when several increases apply in sequence.
Finding the increase between two values divides the difference by the original. That base matters: the same rupee increase looks larger against a smaller starting salary.
Successive increases compound rather than adding. Two consecutive 10% raises produce a 21% total increase, not 20%, because the second is applied to the already-raised figure.
This is worth checking against inflation. A 5% raise in a year when prices rose 6% is a real-terms pay cut, whatever the headline number says.
The formula
Applying a increase
new value = value × (1 + percentage ÷ 100)
Finding the increase between two values
increase % = ((new − original) ÷ original) × 100
The denominator is always the original value, never the new one.
Worked example: a 12% salary increase on ₹50,000
A monthly salary of ₹50,000 rises by 12%.
| Starting salary | ₹50,000 |
|---|---|
| Increase (12% of 50,000) | ₹6,000 |
| New salary | ₹56,000 |
| Multiplier used | 1.12 |
| Two consecutive 10% rises instead | ₹60,500 |
| Total increase from two 10% rises | 21%, not 20% |
The salary rises to ₹56,000. If inflation runs at 6% over the same year, the real increase in purchasing power is closer to 5.7% than 12%.
Things worth knowing
- Percentage increases compound when applied in sequence. Two 10% rises give 21%, not 20%.
- A raise only counts as a real increase if it beats inflation. Compare against the inflation calculator before celebrating.
- Percentage increase from zero is undefined. If a value starts at zero, report the absolute increase instead.
- When comparing job offers, compare in-hand figures rather than CTC percentages — a bigger percentage rise on a worse structure can leave you with less.
