Formula and method

PV = payment × [1 − (1+r)^(-n)] ÷ r

Payments are received at the end of each period. At zero interest the present value is the sum of all payments.

Worked example

Payment per period: 10000, Rate per period (%): 0.5, Number of payments: 120. The result is 900,734.53327167 (present value of annuity).
