How to Calculate Salary Hike Percentage
A salary hike percentage measures the change from the old salary to the new salary relative to the old amount. Subtract the old salary from the new salary, divide by the old salary, and multiply by 100.
Hike percentage formula
((New Salary − Old Salary) ÷ Old Salary) × 100
Revised salary formula
Old Salary × (1 + Hike % ÷ 100)
Example: an annual salary of 800,000 increased to 920,000 has a difference of 120,000. Dividing 120,000 by 800,000 gives 0.15, so the salary hike is 15%.
Fixed Salary, Variable Pay, and CTC
A stated appraisal percentage does not always apply to every part of a compensation package. The detailed planner applies the entered change to fixed salary and keeps current and revised variable pay as separate inputs. This makes it easier to see whether a larger bonus is being presented as part of the overall increase.
Always compare the compensation table in the offer or revision letter. Employer definitions differ, and not every CTC component is paid as monthly cash.
Mid-Year and Prorated Salary Hikes
A hike effective during the year does not produce the full annual increase in that calendar year. The planner includes the selected effective month and calculates the gain for that month through December. A July effective month therefore uses six months of the annual difference.
Payroll cutoffs, a specific effective day, retroactive arrears, unpaid leave, and bonus timing may change the actual result. Use the prorated figure as a planning estimate and confirm the first revised payslip with payroll.
Salary Growth After Inflation
Nominal salary is the amount printed on the compensation letter. Real salary growth estimates how purchasing power changes after inflation. The calculator uses the compound relationship below rather than simply subtracting inflation from the hike.
Real hike formula
((1 + Hike Rate) ÷ (1 + Inflation Rate) − 1) × 100
Future projections compound the selected annual salary growth from the revised package. The today's-money column then discounts those values using the inflation assumption. These are scenarios, not forecasts or guaranteed raises.
Before Accepting a Revised Package
- Confirm whether the percentage applies to fixed pay, gross salary, or total CTC.
- Check variable-pay conditions, payout history, and performance targets.
- Compare employer contributions, insurance, leave, stock, and other benefits.
- Review effective date, arrears, payroll cutoff, and the first revised payslip.
- Estimate taxes and deductions using the rules for your location and situation.
- Compare role scope, working hours, location costs, and career growth—not salary alone.
Take-Home and Projection Disclaimer
Take-home values use simple flat deduction percentages and do not calculate tax slabs, exemptions, payroll contributions, benefits, or jurisdiction-specific rules. Inflation and future hikes are editable assumptions, not predictions. Use the results for comparison and confirm final figures with the employer, payroll team, or a qualified tax professional.
