Syntax Description
INTRATE(settlement; maturity;
investment; redemption; basis)
IPMT(rate; period; NPER; PV; FV;
type)
Calculates the annual interest rate that results when a
security (or other item) is purchased at an investment value
and sold at a redemption value with no interest being paid.
Settlement is the date of purchase of the security. Maturity
is the date on which the security is sold. Investment is the
purchase price. Redemption is the selling price. Basis
indicates how the year is to be calculated.
Calculates the periodic amortization for an investment with
regular payments and a constant interest rate. Rate is the
periodic interest rate. Period is the period for which the
compound interest is calculated. NPER is the total number of
periods during which annuity is paid. Period=NPER, if
compound interest for the last period is calculated. PV is the
present cash value in sequence of payments. FV (optional) is
the desired value (future value) at the end of the periods.
Type (optional) defines whether the payment is due at the
beginning (1) or the end (0) of a period.
IRR(values; guess) Calculates the internal rate of return for an investment. The
values represent cash flow values at regular intervals; at
least one value must be negative (payments), and at least
one value must be positive (income). Values is an array
containing the values. Guess (optional) is the estimated
value. If you can provide only a few values, you should
provide an initial guess to enable the iteration.
ISPMT(rate; period; total_periods;
invest)
MDURATION(settlement; maturity;
coupon; yield; frequency; basis)
MIRR(values; investment;
reinvest_rate)
Calculates the level of interest for unchanged amortization
installments. Rate sets the periodic interest rate. Period is
the number of installments for calculation of interest.
Total_periods is the total number of installment periods.
Invest is the amount of the investment.
Calculates the modified Macauley duration of a fixed interest
security in years. Settlement is the date of purchase of the
security. Maturity is the date on which the security matures
(expires). Coupon is the annual nominal rate of interest
(coupon interest rate) Yield is the annual yield of the security.
Frequency is the number of interest payments per year (1, 2
or 4). Basis indicates how the year is to be calculated.
Calculates the modified internal rate of return of a series of
investments. Values corresponds to the array or the cell
reference for cells whose content corresponds to the
payments. Investment is the rate of interest of the
investments (the negative values of the array) Reinvest_rate
is the rate of interest of the reinvestment (the positive values
of the array).
NOMINAL(effective_rate; Npery) Calculates the yearly nominal interest rate, given the
effective rate and the number of compounding periods per
year. Effective_rate is the effective interest rate Npery is the
number of periodic interest payments per year.
