FgivenA | R Documentation |
Compute F given A
FgivenA(
A,
n,
i,
frequency = c("annual", "semiannual", "quarter", "bimonth", "month", "daily")
)
FA(
A,
n,
i,
frequency = c("annual", "semiannual", "quarter", "bimonth", "month", "daily")
)
A |
numeric vector that contains the annual value(s) |
n |
numeric vector that contains the period value(s) |
i |
numeric vector that contains the interest rate(s) as a percent |
frequency |
character vector that contains the frequency used to obtain the number of periods [annual (1), semiannual (2), quarter (4), bimonth (6), month (12), daily (365)] |
F is expressed as
F = A\left[\frac{\left(1 + i\right)^n - 1}{i}\right]
the "future equivalent"
the "uniform series amount (occurs at the end of each interest period)"
the "effective interest rate per interest period"
the "number of interest periods"
FgivenA numeric vector that contains the future value(s) rounded to 2 decimal places
FA data.frame of both n (0 to n) and the resulting future values rounded to 2 decimal places

# Example 4-7 from the Reference text (page 131-132)
FgivenA(23000, 40, 6, "annual") # the interest rate is 6\%
FA(23000, 40, 6, "annual") # the interest rate is 6\%
