Cigarette and tobacco inventory count: how to work out shrink

Tobacco is small, expensive, and kept behind the counter, which makes it the easiest thing in a c-store to lose track of. The count is simple: what you started with, plus what came in, minus what the POS says sold, is what should be on the shelf. Count what is on the shelf. The difference, at cost, is your shrink.

What to write down

For each item, between two counts (a week is common for cigarettes):

• Begin count: the last physical count.
• Received: units in from the distributor since then, from the invoices.
• Sold: units sold, from the POS item-movement report for the same dates.
• Actual count: what's on the shelf and in the back now.
• Cost per unit: what you paid, not the shelf price.

Pick one unit per line and stick to it. If cigarettes come in cartons and sell as packs, count everything in packs (a carton is ten), or keep cartons and packs as separate lines and record every carton you break open.

The formula

expected      = begin count + received − sold
variance      = actual count − expected
shrink at cost = variance × cost per unit

Negative is missing product. Value it at cost, because cost is what you're out; the lost margin is a second, separate number.

Worked examples

Short. A king-size cigarette, counted in packs at $8.15 cost. Begin 140, received 200, POS sold 231. Expected: 140 + 200 − 231 = 109. On the shelf: 104. Variance −5 packs, −$40.75 at cost.

Balanced. Another cigarette, same cost. Begin 120, received 100, sold 118. Expected 102, counted 102. Variance 0.

Small and probably noise. Moist snuff by the can at $4.20. Begin 48, received 50, sold 61. Expected 37, counted 35. Variance −2 cans, −$8.40.

With a $10-per-item flag, only the first line needs a closer look. Those are lines from the filled example in the kit linked below; across its six sample items the week comes out $57.75 short at cost.

The same thing in a spreadsheet

One row per item. Columns: A = item, B = unit, C = cost per unit, D = begin, E = received, F = sold, G = expected, H = actual, I = variance, J = shrink at cost, K = status. With a $10 flag:

G2:  =N(D2)+N(E2)-N(F2)
I2:  =IF(H2="","",H2-G2)
J2:  =IF(I2="","",I2*C2)
K2:  =IF(J2="","",IF(ABS(J2)>10,"CHECK","OK"))

Fill down and total column J. Next count, copy the actual counts into the begin column. Works the same in Excel, Google Sheets and LibreOffice.

Free download: the tobacco count and shrink sheet (.xlsx, 11 KB; opens in Excel, Google Sheets and LibreOffice; no macros, no sign-up). It's the Tobacco tab from the kit below: 60 item rows starting at row 5, expected, variance and shrink at cost filled in for you, CHECK past the flag you set on the Settings tab ($10 to start), and the total under the last row. Filled with the kit's six sample items it gives the same −$40.75 / $0 / −$8.40 lines as above and $57.75 short in total. All five free sheets are on one page. How to pick the numbers on the Settings tab: setting variance tolerances.

When a line doesn't make sense

1. One brand over, a similar one short by the same amount. Not theft: the clerk scanned one for the other, or a scan code is attached to the wrong item. Look for these pairs before anything else.
2. A carton line short ten, the pack line over ten. A carton was broken into packs and nobody recorded it.
3. A whole delivery's worth over. The distributor invoice was never received into the POS, so the sales came out of stock the system didn't know about. Received should come from the invoice, not from memory.
4. Multipack and promotion sales. A two-pack deal rung as one item, or a promotion code that sells one unit but removes two (or the reverse). Check how the POS records the deal.
5. Count timing. Counting while the store is open, with sales ringing between the shelf count and the report, moves a few units from one week to the next. Count at shift change and pull the POS report at the same moment.
6. Real loss. Steady shortages on high-value items, concentrated on certain shifts, that none of the above explains. Count more often for a few weeks, and compare with who was working.
