Excel Formula Qn for Inventory

L

Hi,

I've been stumped trying to figure the formula for the following problem. Any help is appreciated.

I am creating a financial spreadsheet using Excel for Mac 2011 (v14.3.8) with the following rows (the columns are months of the year):-

Row 1: Pre-sales Inventory
Row 2: Total units ordered by the client
Row 3: Post sales inventory
Row 4: Number of units required
Row 5: Number of units ordered

The problematic formula relates to Row 5. Orders can only be placed in 500 unit batches. I want the system to recognize that if the row 4 cell is negative then a certain amount of stock (row 5 cell) should be ordered. This amount should be in multiples of 500.

To better explain this I've included an example...

B4=A3-B2 The number of units required to be available for February is equal to the post sales inventory for January minus the total units ordered by​
the client. If this number is negative (eg. -240) then the number of units that need to be ordered (cell A5) would be 1 * 500. If the number is -501 then 2*500 and so on. Thus making B1=A3+A5.


​
If you haven't realised, my knowledge of Excel is quite basic. Thanks for your input.

Assuming the spreadsheet as depicted, the formula would go into cell B7. So try this formula in the first cell for Stock Units Ordered, then drag across;
=ROUNDUP(B6/500,0.5)*-500

You should end up with this;
