Example Calculation
Popular Mascara Example
Product: Mascara (0.34 fl oz / 10 mL)
Price: $4.49
Efficiency: 177.4 applications/mL
Usage: 2 coats, once daily
Calculation
Total Applications = (177.4 × 10) ÷ 2 = 887 applications
Cost per Application = $4.49 ÷ 887 = $0.005
Days to Last = 887 ÷ 1 = 887 days (2.4 years!)
Result: Each application costs less than a penny!
