Calculate Any Percentage

How Percentages Work
The word "percent" means "per hundred." So 2% means 2 out of every 100. The formula is: Result = (Percentage / 100) × Amount. For 2% of 100: (2 / 100) × 100 = 2.
Real-World Examples
Shopping: a 2% discount on a $100 item saves you $2. Tips: 2% tip on a $100 bill is $2. Finance: 2% annual return on a $100 investment earns $2 per year. Tax: 2% tax rate on $100 income means $2 in taxes.
Mental Math Tip
To calculate 2% quickly: find 10% first (10), then adjust. 5% is half of 10%. 20% is double 10%. 1% is 10% divided by 10. Combine these building blocks for any percentage without a calculator.
Common Mistakes
Successive discounts do not add up. A 2% discount followed by another 2% discount is NOT 4% off. The second discount applies to the already-reduced price. Also, percentage increase and percentage points are different: going from 2% to 4% is a 2 percentage point increase but a 100% relative increase.
