Calculates the number of periods of an investment involving constant cash flows.
Format: NPER (rate, pmt, pv {,fv}{,type})
Arguments:
ΓÇó rate: Interest rate per period.
ΓÇó pmt: Payment to be made per period.
ΓÇó pv: Present value of the investment.
ΓÇó fv: Optional. Future value of the investment or cash value remaining after final payment. If omitted, assumed to be 0.
ΓÇó type: Optional. Type of payment scheme. (0 or 1; preset to 0, which means payments are due at the end of the period.)
Example:
NPER (10%/12,-250,10000) returns 48.86 months (when using a fixed number format with a precision of 2).
Shows that a £10,000 purchase at a 10% interest rate, monthly payments of £250, and nothing down requires 49 monthly payments (10%/12 is a 10% rate over 12 months).
