Thank you Gary's Student.

(1) How can I convert to a UDF (have never done this before - have read the
documentation, but I guess I need more hand holding in terms of steps)...

(2) How can I run this routine using a sheet with about 30 different form
types, each with a string of monthly receipts - use an array?

Thank you.

This is just an example:

1. put monthly receipt values in column A
2. put the target (fixed) value in cell B1
3. enter and run this macro:


Sub Macro1()
Sum = 0
target = Cells(1, 2).Value
For i = 1 To 65536
Sum = Sum + Cells(i, 1).Value
If Sum = target Then Exit For
denom = Sum
If i = 65535 Then Exit Sub
Next
j = i - 1
result = (target - denom) / Cells(i, 1).Value
Cells(1, 3).Value = j + result
End Sub


It will perform the calculation and enter the result in cell C1. If you are
not familiar with macros, see:

Hello all.

Here is my business problem for which I am seeking a solution:

Desired outcome - generate a cycle time based on varible number of input
values marked agianst a set vaue. Example, I have a fixed value of 1,000,
and a string of consecutive monthly receipt values (from nearest month to
farthest month), say 300, 200, 300, 450. I need a solution to determine how
many times of these values go into 1,000, and the last value expressed as a
decimal, if applicable. So, using the above vlaue would generate a cyckle
time of 3.4444. That is, 300 =1 because 300 < 100, 200 = 2, because 300+200
< 1000, 300 = 3 because 300+200+300 < 1,000., and the difference between
1,000 and 800 divided by 450 = .4444. I have tried countif, sumif, arrays,
and I just can;'t seem to find a solution other than manually performimng the
calucation every time.

Any ideas to create a specialized formula or function to handle this task?

Thank you.
