Q

Effective annual interest rates (EAR)

A

EAR = (1 + r / n) ^ n -1

The higher the # of periods compounded during the year, the higher EAR will be

Q

Annuity

A

finite series of equal payments occuring at regular intervals

Ordinary annuity - payment at end-of-period

PV = PMT [1/i - 1/i(1+i)^n]

Annuity due - payment at beg-of-period

PV = PMT + PMT [1/i - 1/i(1+i)^(n-1)]

Q

Perpetuity

A

periodic same amount cash flows never end

no growth: PV = PMT / i
constant growth: PV = PMT / (i - g)

Q

FV of an annuity

A

an ordinary annuity: FV = PMT [((1+i)^n-1) / i]
an annuity due: FV = (1+i) x PMT [((1+i)^n-1)/i]

Q

Inflation and real rates of return

A

Fisher effect:
(1+inflation rate) x (1 + real rate of return) = (1 + nominal rate of return)
