Hi donkey77!
I'm not sure that I understand what you want but:
Take the following in A1:A9
-100000
10000
25000
20000
15000
12000
15000
12300
13000
In A11:
=IRR(A1:A9,0)
Returns: 4.98763731503295%
To get the periodic equivalent of the payments in A2:A9
=PMT(A11,COUNT(A2:A9),A1,0,0)
Returns: 15464.4500896704
Now to check (one way)
-100000
$15,464.45
$15,464.45
$15,464.45
$15,464.45
$15,464.45
$15,464.45
$15,464.45
$15,464.45
IRR is 4.98763731503295%
Using the same principle of equivalence of payments we can batch up a series
of equal cash flows (eg) per month to equivalent cash flows (eg) per year.
