InterestRate: this is the interest rate per period (expressed as a decimal, 8% = 0.08).
Period: this represents the number of payments made.
Payment: represents the payment made each period.
PV: equals the present value as of the beginning of the period.
AnnuityType: indicates whether payments are made at the beginning or end of the period. 0 indicates payments are made at the end of the period. 1 indicates payments are made at the beginning of the period.
Examples
FV(.08, 30, 822.48, 0, 1): equals -100,627.03, rounded to two decimal places.
This is the future value after 30 years of annual payments of $822.48 made at the beginning of each year, using an annual interest rate of 8% and an initial present value of zero. The result is negative because the payments are entered as positive amounts.
Comments
The sign of payments and present value relative to future value will be opposite.
