❏Present value is calculated by multiplying the amount of each annuity payment by the interest rate between payments and the number of periods in the annuity. As an equation, it is: PV = PMT * [(1-(1+r)^-n)/r], in which PV = present value, PMT = payment amount, r = interest rate and n = number of periods
