Shrinkage Rate Calculator
Inventory lost to theft, damage, admin error, or supplier fraud, as a % of sales.
A silent margin killer. The industry average is ~1.5% of sales — every 0.1% reduction drops straight to profit.
- Formula
- (Recorded Inventory − Actual Inventory) ÷ Net Sales × 100

How to read it
Shrinkage is the gap between the stock your system says you hold and the stock actually there, measured against sales. A result of 0.3% is strong; the industry generally sits nearer 1.5%. Because it is expressed against net sales, the figure only compares fairly between stores of similar turnover — a small store losing the same riyals as a large one will show a much worse percentage.
Common mistake
Assuming it is all theft. In most retail businesses a large share of shrink is administrative: receiving errors, unrecorded damages, markdowns never entered, transfers that left one store and never arrived at the other. Launching a loss-prevention programme against a paperwork problem spends money and changes nothing. Separate the causes you can identify before you act on the ones you cannot.
What to do about it
Shrink above 2% needs the count before the campaign. Cycle-count the highest-value categories first and compare the error pattern against the receiving log — if the gaps cluster around delivery days, the problem is at the back door rather than the shop floor. Every 0.1% recovered drops straight to profit, which is why this is usually the cheapest margin available to a store manager.
Questions
What is an acceptable shrinkage rate?
Under 1% is excellent, around 1.5% is common, and over 2% warrants investigation. The direction matters more than the level — a stable 1.8% is a different problem from a 1.2% that has doubled in two quarters.
Should shrinkage be measured at cost or at retail?
At cost for the profit impact, at retail for the sales impact. Be explicit about which, because the two can differ by the whole margin and are often quoted interchangeably.
How often should we count?
Full counts twice a year, with cycle counts monthly on high-value and high-risk lines. Shrink discovered at an annual count is a year old and untraceable.
