ISPMT Function
The ISPMT function is one of the financial functions. It is used to calculate the interest payment for a specified period of an investment based on a constant payment schedule.
The ISPMT function syntax is:
ISPMT(rate, per, nper, pv)
where
rate is the interest rate for the investment.
per is the period you want to find the interest payment for. The value must be from 1 to nper.
nper is a number of payments.
pv is a present value of the payments.
Note: cash paid out (such as deposits to savings) is represented by negative numbers; cash received (such as dividend checks) is represented by positive numbers. Units for rate and nper must be consistent: use N%/12 for rate and N*12 for nper in case of monthly payments, N%/4 for rate and N*4 for nper in case of quarterly payments, N% for rate and N for nper in case of annual payments.
The numeric values can be entered manually or included into the cell you make reference to.
