TERM Function
The TERM function calculates the number of payment periods required to reach the future value.
This function works in much the same way as the NPER(rate, pmt, pv, fv, type) function does in Mircosoft Excel. For more information on that function you can see the Microsoft Office help for NPER.
Providing the interest rate, payment amount, and the future value, this function returns the number of periods required to pay the loan off completely.
TERM is one of Author's financial expressions and can be used in calculating savings, loans or investment values.

Example
If you have an annual rate of 7.5% paying $100 a month and you know that the future value is $4,023.1381682 then you can work out how many months you need to reach that amount by using the following figures:
- rate: 0.00625 (0.075/12 to find the monthly rate)
- payment: -100
- present value: 0
- future value: 4,023.1381682
- type: 0
The following script would return 36:
TERM ( 0.00625, -100, 0, 4023.1381682, 0)
