Valuing level cash flows, annuities and perpetuities
Annuity: finite series of equal payments that occur at regular intervals.
• If the first payment occurs at the end of the period, it is called an ordinary annuity.
• If the first payment occurs at the beginning of the period, it is called an annuity due. (only
understand the concept for annuity due, not calculations)
Perpetuity: infinite series of equal payments. (last forever)
PVA - present value annuities
FVA- future value annuities
CF- cash flow
Perpetuities:
• An annuity in which the cash flows continue forever.
• Formula:

Document Summary
Future and present values of multiple cash flows: valuing level cash flows: annuities and perpetuities, comparing rates: the effect of compounding periods. Annuity: finite series of equal payments that occur at regular intervals. If the first payment occurs at the end of the period, it is called an ordinary annuity. If the first payment occurs at the beginning of the period, it is called an annuity due. (only understand the concept for annuity due, not calculations) Perpetuity: infinite series of equal payments. (last forever) Perpetuities: an annuity in which the cash flows continue forever. In addition to constant cash flow streams, one may have to deal with cash flows that grow at constant rate over time: these cash flow streams called growing perpetuities. Effective annual rate (ear): this is the actual rate paid (or received) after accounting for compounding that occurs during the year.
