1. What is Pay Percentage Change?

The Pay Percentage Change calculates the relative difference between old and new pay amounts. It shows how much a salary has increased or decreased as a percentage of the original amount.

2. How Does the Calculator Work?

The calculator uses the percentage change formula:

Where:

• New Pay — The current or proposed pay amount
• Old Pay — The previous pay amount

Explanation: The formula calculates the difference between new and old pay as a proportion of the old pay, then converts it to a percentage.

3. Importance of Pay Percentage Change

Details: Understanding pay changes as percentages helps compare salary adjustments across different income levels and provides clearer insight into the real impact of pay changes.

4. Using the Calculator

Tips: Enter both old and new pay amounts in dollars. The calculator will show the percentage increase or decrease. Old pay must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What does a negative percentage mean?
A: A negative percentage indicates a pay decrease, while positive shows an increase.

Q2: How is this different from absolute change?
A: Absolute change shows dollar difference (new-old), while percentage change shows relative difference, which is more meaningful for comparison.

Q3: Why can't old pay be zero?
A: Division by zero is mathematically undefined. You can't calculate percentage change from nothing.

Q4: How should I interpret a 10% increase?
A: A 10% increase means the new pay is 110% of the old pay (or 1.1 times the old amount).

Q5: Can I use this for hourly wage changes?
A: Yes, the calculator works for any pay comparison - salary, hourly wage, or total compensation.
