Hike Percentage = ((New Salary – Old Salary) / Old Salary) × 100
Hike Amount = New Salary – Old Salary
Percentage Increase = (Hike Amount / Old Salary) × 100
If old salary is 50,000 and new salary is 55,000, hike percentage = ((55,000 – 50,000) / 50,000) × 100 = 10%
If old salary is 40,000 and new salary is 46,000, hike percentage = ((46,000 – 40,000) / 40,000) × 100 = 15%
