Key Concepts
- Compound interest: A = P(1 + r/n)^(nt)
- EMI amortizes principal and interest over equal monthly payments.
- APR must include compounding frequency to compare loans fairly.
- Inflation erodes purchasing power — real return = nominal − inflation.
- Profit margin = (Revenue − Cost) / Revenue × 100%.
Common Mistakes
- Using annual rate without converting to monthly for EMI
- Ignoring fees, taxes, and insurance in mortgage totals
- Comparing simple vs compound interest scenarios
- Confusing markup with profit margin
