Returns the interest payment for a given period of an annuity based on periodic, constant payments and a constant interest rate.
IPmt(rate, per, nper, pv, fv, due)
An annuity is a series of constant cash payments made over a period of time. An annuity can be a loan (such as a home mortgage) or an investment (such as a monthly savings plan).
The IPmt function uses the following numeric arguments:
rate Interest rate per period. For example, if you get a car loan at an annual percentage rate (APR) of 10 percent and make monthly payments, the rate per period is 0.1/12, or 0.0083.
per Payment period in the range 1 through nper.
nper Total number of payment periods in the annuity. For example, if you make monthly payments on a four-year car loan, your loan has a total of 4 * 12 (or 48) payment periods.
pv Present value, or value today, of a series of future payments or receipts. For example, when you borrow money to buy a car, the loan amount is the present value to the lender of the monthly car payments you will make.
fv Future value or cash balance you want after you've made the final payment. The future value of a loan, for instance, is $0. As another example, if you will need $50,000 in 18 years to pay for your child's education, then $50,000 is the future value.
due Number indicating when payments are due. Use 0 if payments are due at the end of the payment period, and use 1 if payments are due at the beginning of the period.
The arguments rate and nper must be calculated using payment periods expressed in the same units. For example, if rate is calculated using months, nper must also be calculated using months.
For all arguments, cash paid out (such as deposits to savings) is represented by negative numbers; cash received (such as dividend checks) is represented by positive numbers.
Distribution Note When you create and distribute applications that use any of the financial functions, you should install the file MSAFINX.DLL in the customer's Microsoft Windows \SYSTEM directory.
