Real-World Financial Examples
Business & Investment Scenarios
Revenue: $50,000, Costs: $35,000, Profit: $15,000
Profit Margin = $15,000 ÷ $50,000 = 30%
Bought at $100, Sold at $125
Return = ($125 - $100) ÷ $100 = 25% gain
5% commission on $80,000 sales
Commission = 5% of $80,000 = $4,000
Daily Life Financial Calculations
Meal cost: $85, Tip rate: 18%
Tip = 18% of $85 = $15.30
Purchase: $200, Tax rate: 8.5%
Tax = 8.5% of $200 = $17.00
Original: $150, 30% off sale
Final Price = $150 - (30% of $150) = $105
Loan & Interest Calculations
Loan: $10,000, Interest rate: 6.5%
Annual Interest = 6.5% of $10,000 = $650
House price: $300,000, 20% down
Down Payment = 20% of $300,000 = $60,000
Balance: $5,000, Minimum: 2%
Min Payment = 2% of $5,000 = $100
Business Growth & Metrics
Last year: $100K, This year: $125K
Growth = ($125K - $100K) ÷ $100K = 25%
1,000 visitors, 45 purchases
Conversion = 45 ÷ 1,000 = 4.5%
Your sales: $2M, Total market: $20M
Market Share = $2M ÷ $20M = 10%

Advanced Percentage Formulas & Financial Impact
A $1,000 investment with 7% annual growth becomes $7,612 after 30 years. Even 1% difference (6% vs 7%) results in $1,400 less final value.
Interest rate change from 3% to 4% is a 1 percentage point increase, but a 33% relative increase (1÷3 = 0.33).
If costs are 70% of revenue, you need 42.8% revenue increase to double profits (mathematical leverage effect).
