Parameters

  • Arg2
    Type: System.Double

    Per - the period for which you want to find the interest and must be in the range 1 to nper.

  • Arg3
    Type: System.Double

    Nper - the total number of payment periods in an annuity.

  • Arg4
    Type: System.Double

    Pv - the present value, or the lump-sum amount that a series of future payments is worth right now.

  • Arg5
    Type: System.Object

    Fv - the future value, or a cash balance you want to attain after the last payment is made. If fv is omitted, it is assumed to be 0 (the future value of a loan, for example, is 0).

  • Arg6
    Type: System.Object

    Type - the number 0 or 1 and indicates when payments are due. If type is omitted, it is assumed to be 0.

Return Value

Type: System.Double

Remarks

If payments are due

0

1

Make sure that you are consistent about the units you use for specifying rate and nper. If you make monthly payments on a four-year loan at 12 percent annual interest, use 12%/12 for rate and 4*12 for nper. If you make annual payments on the same loan, use 12% for rate and 4 for nper.

For all the arguments, cash you pay out, such as deposits to savings, is represented by negative numbers; cash you receive, such as dividend checks, is represented by positive numbers.
