The present value (PV) of an annuity is the value today of a series of payments in the future. It uses a payment amount, number of payments, and rate of return to calculate the value of the payments in today’s dollars.
- “Payment” is the payment each period.
- “Rate of Return” is a decimal rate of return per period (the calculator above uses a percentage). A return of 2.2% per period would be calculated in the formula as “0.022”.
- “Number of Periods” is the number of periods (any payments).
We will receive $100 each year for the next 10 years. The interest rate at the moment is 2.2% compounded annually. What is the present value of this annuity?
