Calculate Any Percentage
Step-by-Step Solution

How Percentages Work
The word "percent" means "per hundred." So 7% means 7 out of every 100. The formula is: Result = (Percentage / 100) × Amount. For 7% of 100: (7 / 100) × 100 = 7.00.
Real-World Examples
Shopping: a 7% discount on a $100 item saves you $7.00. Tips: 7% tip on a $100 bill is $7.00. Finance: 7% annual return on a $100 investment earns $7.00 per year. Tax: 7% tax rate on $100 income means $7.00 in taxes.
Mental Math Tip
To calculate 7% 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 7% discount followed by another 7% discount is NOT 14% off. The second discount applies to the already-reduced price. Also, percentage increase and percentage points are different: going from 7% to 14% is a 7 percentage point increase but a 100% relative increase.
