Given:
C = Principle
P = Payment
i = interest
n = months or quarters or years, etc
(i must be related to n)


P - C i
Log -----------
P
n = ----------------------
1
Log ----------
1 + i

I don't know how/if Excel handles this formula.
For finacial calculations I do normally use
mathematical formulas.

Bruce's formula is correct. I am not sure if there is a direct formula that
returns period, but:


put 5 in A1 (years)
put 8% in B1 (rate)
put 100 in C1 (payment)
put 0 in D1 (type)
put =PV(B1/12,A1*12,-C1,0,0) in E1 (amount financed)

you will see $4,931.84 in E1. Since you want to calculate the years and not
the amount financed), then click on E1 and pull-down:

Tools > Goal Seek... and enter your desired amount inthe value field and A1
in the changing field.

You will now have the payoff time.
 
Thank you gentlmen, you have been most helpful!
