Basic Percentage Calculation
Basic percentage calculation finds the percentage value of a specific number:
- Stock Investment Example: To calculate 20% profit on $1,000 investment
$1,000 × 20% = $200 (Profit) - Discount Calculation Example: To calculate 30% discount on $50 item
$50 × 30% = $15 (Discount amount)
$50 - $15 = $35 (Final price) - Tax Calculation Example: To calculate 22% income tax on $50,000 salary
$50,000 × 22% = $11,000 (Tax amount)
Percentage Change Calculation
Calculate the percentage rate of change between two values:
- Stock Return Example: If $1,000 investment becomes $1,200
((1,200 - 1,000) ÷ 1,000) × 100 = 20% increase - Revenue Growth Example: Last year $50,000, This year $40,000
((40,000 - 50,000) ÷ 50,000) × 100 = -20% decrease - Inflation Rate Example: Last year $3.00, This year $3.30
((3.30 - 3.00) ÷ 3.00) × 100 = 10% increase
