Salary Increase Percentage = ((New Salary – Old Salary) / Old Salary) × 100
Subtract the old salary from the new salary
Divide the result by the old salary
Multiply by 100
Example: Old Salary = 50,000; New Salary = 55,000
Salary Increase Percentage = ((55,000 – 50,000) / 50,000) × 100
Salary Increase Percentage = (5,000 / 50,000) × 100
Salary Increase Percentage = 10%
