Explanation: The difference between new and old values is divided by the old value, then multiplied by 100 to convert to a percentage.

Q1: What does a negative result mean?
A: A negative result indicates a percentage decrease rather than an increase.
Q2: Can I use this for financial calculations?
A: Yes, this is commonly used to calculate investment returns, price changes, and revenue growth.

A: The calculation is undefined when old value is zero, as division by zero is impossible.
Q4: How is this different from percentage difference?
A: Percentage increase compares new to old specifically, while percentage difference is symmetrical and doesn't indicate direction of change.
Q5: Can I calculate percentage decrease with this?
A: Yes, when new value is less than old value, the result will show the percentage decrease.
