Exponential Compounding Growth: Returns generate subsequent returns over time t, rapidly accelerating capital growth.
Common Mistakes & Traps
- Entering annual percentage rate (e.g. 7%) as 7 instead of converting to decimal 0.07.
- Neglecting the compounding frequency (n): monthly compounding produces higher yield than annual.
- Ignoring inflation drag when evaluating long-term nominal returns.

Worked Example: Profit Margin
Given:
- revenue = 1000
- cost = 600

- Margin = (400 / 1000) × 100
- Margin = 40%
- Markup = (400 / 600) × 100 = 66.67%
Answer: 40
