What is 1% of 100?
Calculate Any Percentage
Step-by-Step Solution
- Write 1% as a decimal: 1 ÷ 100 = 0.01
- Multiply: 0.01 × 100 = 1
Formula: Percentage × Amount ÷ 100 = Result
How Percentages Work
The word "percent" means "per hundred." So 1% means 1 out of every 100. The formula is: Result = (Percentage / 100) × Amount. For 1% of 100: (1 / 100) × 100 = 1.
Real-World Examples
Shopping: a 1% discount on a $100 item saves you $1. Tips: 1% tip on a $100 bill is $1. Finance: 1% annual return on a $100 investment earns $1 per year. Tax: 1% tax rate on $100 income means $1 in taxes.
Mental Math Tip
To calculate 1% 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 1% discount followed by another 1% discount is NOT 2% off. The second discount applies to the already-reduced price. Also, percentage increase and percentage points are different: going from 1% to 2% is a 1 percentage point increase but a 100% relative increase.
