PgivenF | R Documentation |
Compute P given F
PgivenF(
F,
n,
i,
frequency = c("annual", "semiannual", "quarter", "bimonth", "month", "daily")
)
PF(
F,
n,
i,
frequency = c("annual", "semiannual", "quarter", "bimonth", "month", "daily")
)
F |
numeric vector that contains the future 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)] |
P is expressed as
P = F\left[\frac{1}{\left(1 + i\right)^n}\right]
the "present equivalent"
the "future equivalent"
the "effective interest rate per interest period"
the "number of interest periods"
PgivenF numeric vector that contains the present value(s) rounded to 2 decimal places
PF data.frame of both n (0 to n) and the resulting present values rounded to 2 decimal places

# Example 4-4 from the Reference text (page 128)
PgivenF(10000, 6, 8, "annual") # the interest rate is 8%
PF(10000, 6, 8, "annual") # the interest rate is 8%
