Worked Examples
Online Store – Single SKU
Fixed Costs: $30,000
Price: $25
Variable Cost: $15
Units = 30,000 ÷ (25 − 15) = 3,000 units
Dollars = 30,000 ÷ (25 − 15)/25 = $75,000
Dollars = 30,000 ÷ (25 − 15)/25 = $75,000
Consulting Firm – Service
Fixed Costs: $50,000/year
Hourly Rate: $150
Variable Cost: $60/hour
Hours = 50,000 ÷ (150 − 60) ≈ 556 hours
Revenue = 50,000 ÷ 0.60 ≈ $83,333
Revenue = 50,000 ÷ 0.60 ≈ $83,333
