1. The present value of an annuity can be calculated using the formula PV = Pmt × [(1 - (1 + r)^-n) / r], where Pmt is the payment amount, r is the interest rate per period, and n is the number of periods.
2. The future value of an annuity can be calculated using the formula FV = Pmt × [((1 + r)^n - 1) / r].
3. Annuities can be classified into ordinary annuities (payments at the end of each period) and annuities due (payments at the beginning of each period).
4. In capital budgeting, annuities are used to evaluate projects with recurring cash flows, making it easier to compare different investment opportunities.
5. Understanding annuities is crucial for calculating loan repayments, retirement planning, and any financial scenario involving regular payments.
