A: A negative percentage indicates a decrease rather than an increase between the old and new values.

Q2: Why can't the old value be zero?
A: Division by zero is undefined in mathematics, so the calculation requires a non-zero old value.

Q3: How is this different from percentage points?
A: Percent increase measures relative change, while percentage points measure absolute difference between percentages.

Q4: Can I use this for percentage decrease?
A: Yes, the same formula works - a decrease will simply show as a negative percentage.

Q5: What are common applications of this calculation?
A: Useful for financial growth analysis, price changes, population growth, performance metrics, and more.
