How to compute a future value if the given is only the interest rate, periods per year and the present value?

Question

How to compute the payments per period?

Answer 1

The formula for Future Value is :

FV = P x (1 = i)^n

where P = principal or present value

i = interest rate

n = no. of periods

If you have everything except FV, you can easily solve for FV

Answer 2

I assume that you are using a financial calculator.  If you are, payments per year are 0.  Just enter:

Present Value:  Whatever it is.

Periods per Year:  1

Interest (per year):  whatever is given.

Then compute for future value.  Remember to set the calculator at "beginning" (that you will be making the single payment at the beginning of the period).
