Here's an example of a WebFOCUS function for a different calculation you could follow to write the NPER function yourself.

That's how I came up with the code below which calculates Periods in a function using the formula from this site: https://help.anaplan.com/anape...ctions/All/NPER.html.
```
SET PAGE = OFF
DEFINE FUNCTION NPER (P/D12.2, F/D12.2, PMT/D12.2, R/D12.2, T/I1)
-* Note:
-*  LOG((-R*F+PMT*(1+Rate*Type))/(Rate*Pv+PMT*(1+Rate*Type)))/LOG(1+Rate)
-*  Input Parms:
-*  Present Value         = P
-*  Future Value          = F
-*  Payment             =PMT
-*  Interest              = R
-*  Type                  =T

NPER/D12.2 = LOG((-R*F+PMT*(1+R*T)) / (R * P+PMT*(1+R*T)))/LOG(1+R);
END
-*
DEFINE FILE CAR
PERIODS/D12.2 = NPER(-10487,4000,300,.0040,0);
END
-*
TABLE FILE CAR
"Example of NPER"
"Number of Periods"
PRINT
PERIODS
BY COUNTRY

ON TABLE SET STYLE *
ENDSTYLE
END```
