Connect the ideas.
- Identify the principal, rate base, timing and complete cash flows before calculating.
- Simple interest uses the original principal; compound interest repeatedly updates the balance.
- For nominal compounding, periodic rate=r/m and number of periods=mt.
- Present value reverses growth by division; a minimum deposit is rounded upward to cents.
- Compare effective annual growth and net balances after supplied fees and tax.
- Share profit includes purchase/sale costs and supplied dividends; an ROI needs a stated base and period.
- Credit comparisons need deposits, all repayments and fees, not just an advertised monthly payment.
- Real purchasing-power growth uses a ratio of growth and inflation factors; every conclusion is conditional on the model.
