REMARKS

* A negative number represents any cash you pay out.
* A positive number represents any cash you receive (start with or end with).
* The "rate" and "nper" MUST be expressed in the same units of time: years, months or days.
* The present value is the total amount that the payments are worth now.
* If "fv" is left blank, then 0 is used.
* If "type" is left blank, then 0 is used.
* If "type" = 0, then payments are made in arrears.
* If you add the PPMT and the IPMT for the same period you will get the PMT.
* You can use the IPMT function to return the interest amount paid on a given period on a loan with fixed interest.
* You can use the PMT function to return the full amount (principal + interest) paid every period on a loan with fixed interest.
* The equivalent VBA function is VBA.PPMT
