After you do a stocktake, it's time to do something with it. You will need the following numbers for your financial figures.
1) The value of your stock (Perpetual stock value) that your computer thinks that it had before you did the stocktake. Print out a report of your stock valuation before starting the stocktake.
If you do not trust the figure in your point of sale software, then you can, or your accountant can give you an estimate. This is NOT recommended.
2) The value of the stock (Physically Counted Inventory Value) you have at the end of this financial year that you.
Now do the following calculation.
Shrinkage% = (1- (Physically Counted Inventory Value))/(Perpetual stock value)) x 100%
A familiar figure here is about 1.4%, but it does vary a lot. I have seen figures between 0.1% and 6%. What COVID will do to your figures is anyone guess.
3) Value of the damaged goods you counted. (Damaged stock value)
It would be best if you looked at is your damaged goods too. These have a different story, and it can be an exciting story to tell.
Damaged% = (Damaged stock value)/(Sales of stock product) x 100%
Once you get these figures, please let me know as I am interested in this stuff.
