The Annuity Payment based on Present Value calculator computes the payment from a fixed rate (r) annuity, loan or structured settlement over a number of periods (n).

INSTRUCTIONS: Choose the preferred currency units and enter the following:

• (PV) This is the present value of the annuity.
• (r) This is the fixed interest rate per period.
• (n) This is the number of periods.

Annuity Payment: The calculator returns the payment value in U.S. dollars. However, this can be automatically converted to other currencies via the pull-down menu.

The Math / Science

The annuity-payment formula is used to calculate the periodic payment on an annuity (i.e. a series of periodic payments that are received at a future date). The formula assumes that the rate does not change, the payments stay the same, and that the first payment is one period away.

`P = (r * PV)/(1-(1+r)^(-n))`

where:

• PV is the Present Value
• r is the fixed interest rate per period
• n is the number of periods
