Frequently Asked Questions
How do you calculate a percentage?
To calculate a percentage, you typically divide the 'part' by the 'whole' and then multiply the result by 100. For example, to find what percentage 20 is of 50, you would perform the calculation (20 / 50) * 100, which equals 40%.
What is the formula for percentage change?
The formula for percentage change is: ((New Value - Original Value) / Original Value) * 100. A positive result from this formula indicates a percentage increase, while a negative result indicates a percentage decrease.
How can I calculate a discount using this calculator?
To calculate a discount, select the 'What is X% of Y?' operation. For example, to find a 25% discount on a $80 item, you would enter 25 for the percentage (X) and 80 for the value (Y). The result ($20) is your discount amount. The final price would be $80 - $20 = $60.
