Frequently Asked Questions
How do I calculate a percentage of a number?
To calculate X% of Y, multiply Y by X/100. For example, to find 25% of 80: 80 × (25/100) = 80 × 0.25 = 20. Our calculator handles this automatically - just enter your values in the 'Basic Percentage' tab.
How do I calculate percentage change?
To calculate percentage change: subtract the original value from the new value, divide by the original value, then multiply by 100. For example, if a price changes from $50 to $60, the percentage change is: ((60-50)/50) × 100 = 20% increase.
What's the formula to calculate a value after percentage increase?
To find a value after a percentage increase, multiply the original value by (1 + percentage/100). For example, to increase 50 by 20%: 50 × (1 + 20/100) = 50 × 1.2 = 60.
How do I calculate how much is saved from a discount?
To calculate savings from a discount, multiply the original price by the discount percentage divided by 100. For example, if an item costs $80 with a 25% discount, the savings are: $80 × (25/100) = $80 × 0.25 = $20.
