Frequently Asked Questions-

1. What is the formula to calculate percentage decrease?
   The formula to calculate percentage decrease is:

   $$\text{Percentage Decrease} = \frac{\text{Original Value} - \text{New Value}}{\text{Original Value}} \times 100$$

   This formula calculates how much the original value has decreased as a percentage of the original value.

2. What is the difference between percentage decrease and percentage increase?

   • Percentage Decrease measures the reduction in value from the original value to the new value.
   • Percentage Increase measures the increase in value from the original value to the new value.

   Both calculations use similar formulas but differ in the direction of change (decrease vs. increase).

3. Can the percentage decrease be negative?
   No, the percentage decrease cannot be negative. If the new value is greater than the original value, the result will indicate a percentage increase, not a decrease. In such a case, you would need to use a percentage increase calculator.

4. Can I use the calculator for prices and sales?
   Yes, the percentage decrease calculator is commonly used to calculate discounts or price reductions. For example, if a product originally costs $100 and is now priced at $75, the percentage decrease is 25%.

5. Can I calculate percentage decrease for values with decimals?
   Yes, the calculator can handle values with decimals, making it useful for calculating percentage decreases in financial figures, measurements, or other contexts where decimal values are common.
