>Remember the formula for SFF:
>i / (1-i^n)-1 = SFF
>i = the interest rate
SFF = mortgage constant - interest rate
where mortgage constant is just your regular = PMT (Interest rate/12,years*12,1)
The above mentioned is Excel function. You have similar function in HP12c and TI calculators.
No need to remember SFF formula actually. |
