You just have to reverse engineer it.

Wow that is much simpler then I thought. You don't need the inventory or
the
cost of goods sold as long as you have the turn rate. Thanks a Bunch!

Ok here it is:

A B C D
1
2 12 3 3 17.333

Cells A2 and B2 are values entered:
A2: 12
B2: 3

Cells C2 and D2 are formulas:
C2: =B2*12/A2 [which returns 3]
D2: =A2/(SUM(B2*12)/52) [which returns 17.333]

A2 = Inventory
B2 = Cost of Goods Sold
C2 = Turn Rate
D2 = Weeks Supply

Is it possible to come up with D2 (Weeks Supply) by using only

A2 (Inventory) and C2 (Turn Rate)

or by using only

B2 (Cost of Goods Sold) and C2 (Turn Rate)?

You will need to spell it all out again because none of it makes any
sense
now. The formula you give now returns 3 not 17.333.

I goofed and had one of the formulas backwards
Original: A3 = =A1*12/A2 [this give me the turn rate of: 3
Corrected: A3 = =A2*12/A1 [this give me the turn rate of: 3

I'm not sure if that had anything to do with it or not but weeks
supply
using these numbers is 17.333. Your formula =A3/144*52 returns
1.0833.

A1 = Monthly Inventory Value of 12
A2 = Monthly Cost of Goods Sold of 3
A3 = =A1*12/A2 [this give me the turn rate of: 3

To calculate the weeks supply of product I would use the
following
formula:
=A1/SUM(SUM(A2*12)/52) [this gives me 17.333 weeks supply]

It would be helpful to have a calculation that could arrive at
the
weeks
supply without having to have access to both the Inventory Value
or
the
Cost
of Goods Sold.

Is it possible to calculate the Weeks supply with only the turn
rate
and
one
of the other two? In other words if all you had was the turn rate
and
the
inventory or just the turn rate and the cost of goods sold, could
you
come
up
with the weeks supply?
