1. What is Percentage Increase?

Percentage increase measures how much a value has grown relative to its original amount, expressed as a percentage. It's commonly used to calculate salary raises, price changes, and growth rates.

2. How Does the Calculator Work?

The calculator uses the percentage increase formula:

Where:

• New Value — The current or increased amount
• Old Value — The original or previous amount

Explanation: The formula calculates the difference between new and old values, divides by the original value to get relative change, then converts to percentage by multiplying by 100.

3. Importance of Percentage Increase Calculation

Details: Calculating percentage increases helps in financial planning, evaluating raises, comparing growth rates, and making informed decisions about salary negotiations or investments.

4. Using the Calculator

Tips: Enter both salary amounts in the same currency. The old salary should be the original amount, and the new salary should be the increased amount. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between percentage increase and absolute increase?
A: Absolute increase shows the numerical difference (New - Old), while percentage increase shows the relative change compared to the original value.

Q2: Can the percentage increase be negative?
A: Yes, if the new value is less than the old value, the result will be negative, indicating a percentage decrease.

Q3: How do I interpret a 50% increase?
A: A 50% increase means the new value is 1.5 times the original value (original + half of original).

Q4: Does the calculator work for any currency?
A: Yes, as long as both values are in the same currency. The percentage result is currency-independent.

Q5: What if my old salary was zero?
A: The calculation is undefined when the old value is zero, as you cannot divide by zero. The calculator requires positive values.
