Connect the ideas.
- Match the decimal interest rate and the exponent to the same period.
- Simple and straight-line models add fixed amounts; compound and reducing-balance models multiply current amounts.
- Interest is not the same as the final balance or total contributions.
- Payment timing determines the recurrence rule.
- Combine successive percentage factors by multiplication.
- Check fees, domains, assumptions and digital formulas before interpreting the answer.
