Convert Turn Rate to Weekly Supply

[Joe]

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?

 

[Bob Phillips]

=A3/144*52

 

[Joe]

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.

=A3/144*52

[Joe]

Thank you for your help in simplifing =A1/SUM(SUM(A2*12)/52) but that really
is not the problem I am trying to solve.

I am trying to come up with a formula that will allow me to back into the
weeks supply without have to have both the inventory and the cost of goods
sold at the same time by using the turn rate as a substitute for one of them.

Thanks

Perhaps, Joe, you could give us a clue what you intended the two SUM
functions to achieve in
=A1/SUM(SUM(A2*12)/52) when you haven't given the function a number of
arguments to sum?
Why not just =A1/((A2*12)/52) ?

or, of course, =A1/(A2*12/52)

If you don't understand what the SUM function does, look it up in
Excel help.

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.

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)?

[Fred Smith]

To calculate weeks' supply from turn rate, use:

=52/a3

Where a3 is your turn rate. You don't need either inventory or COGS.

Regards,
Fred.

Try

=52/C2

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!

[Fred Smith]

Yes. Basically the supply period is the reciprocal of the turn rate. Glad it
worked for you. Thanks for the feedback.

You just have to reverse engineer it.
