How to cost packaging and labels per unit

To cost packaging and labels, divide what you paid for each pack by the units you actually get out of it, then add up everything that leaves with one unit: bottle, cap, label, seal, bag. For a bottled sauce, that total can come close to the cost of the sauce itself. Leave it out and your price covers what is in the bottle but not the bottle.

What counts as packaging

Everything the customer takes home with the product, plus anything you use to get it to them in one piece:

• Main container: jar, bottle, tub, box, resealable bag.
• Closure: cap, lid, shrink band, tape, tamper sticker.
• Identification: label, date sticker, card.
• Per order: carrier bag, tissue, napkin, cutlery, insulated bag.
• Protection: baking paper, dividers, card inserts, bubble wrap if you post.

All of this is part of the loaded cost of each unit, alongside ingredients, your time and monthly overhead. It is one of the easier hidden costs of a food business to work out, because every item has a clear price and quantity.

Step 1: price per piece

The sum is always the same:

cost per piece = pack price ÷ usable pieces in the pack

"Usable" matters. If 4 labels out of every 100 crease or go on crooked, the 96 good ones carry the cost of all 100. If a case of bottles always has one chipped, same thing. Track your losses over one or two orders and use that figure.

Step 2: add up what one unit uses

Make the list per product, not per purchase. A bottle of sauce and a boxed brownie use different packaging, even if you bought everything on the same trip to the cash and carry.

Step 3: spread what goes per order

Bags, tissue paper and napkins go with each order, not each unit. Divide their cost by the units in a typical order. If most customers buy two bottles, a $0.12 bag adds $0.06 per bottle.

If a channel needs extra packaging (a sealed bag for delivery, a sturdier box for a shop), work out a packaging cost per channel. The same product can have two packaging costs.

Worked example: a 150 ml bottle of hot sauce

You sell hot sauce in 150 ml glass bottles at $9.00. You have already worked out that the sauce (chillies, vinegar, garlic, salt, a little sugar) costs $1.10 per bottle. This is what you buy to bottle it:

• Bottle and cap: case of 48 for $40.80 → 40.80 ÷ 48 = $0.85.
• Labels: 250 printed labels for $72.00. About 10 get spoiled applying them → 72.00 ÷ 240 = $0.30.
• Shrink bands: 500 for $20.00 → 20.00 ÷ 500 = $0.04.
• Carrier bag: $0.12 each. An average order is 2 bottles → $0.06 per bottle.

With the sauce, the material cost per bottle is $1.10 + $1.25 = $2.35. Packaging is 1.25 ÷ 2.35 = 53% of what you spend on materials, and 1.25 ÷ 9.00 = 13.9% of the price.

Here is the effect on margin, counting only materials for now:

• Sauce only: (9.00 − 1.10) ÷ 9.00 = 87.8%.
• Sauce and packaging: (9.00 − 2.35) ÷ 9.00 = 73.9%.

Nearly 14 points of margin are gone before you count your time, energy or rent.

Ordering more labels: when it pays

The printer offers 1,000 labels for $180.00 instead of 250 for $72.00.

• 250 labels: 72.00 ÷ 250 = $0.288 each.
• 1,000 labels: 180.00 ÷ 1,000 = $0.18 each.

You save $0.108 per label, about $108 across the 1,000. But you pay $180 today instead of $72, and at 60 bottles a month those labels last well over a year. In that time you may change the recipe, the design, your address or the wording your local rules require. If that happens after six months, you throw away about 640 labels and the saving turns into a loss.

A practical rule: order what you will use in three to six months, unless you are sure the label will not change.

Label design and other one-off costs

Design, a stamp, or a printing plate are paid once. Do not fold them into every label as if they repeat. Spread them over the first print run, or treat them as overhead and add them to the monthly pool, as explained in how to allocate overhead to products. A $120 design spread over 1,000 labels adds $0.12 per bottle, and only while those 1,000 last.

Bottling time costs money too

Filling, capping, shrinking the band, labelling and dating take time. At 45 seconds a bottle, a batch of 40 bottles takes 30 minutes. That time does not go in the packaging cost; it goes in your labour. See how to cost your own labour.

What the label has to say

Before you order 1,000 labels, check what they must include. The guide to what goes on a food label covers the usual elements. Requirements differ by country and by where you sell, so check with your local food authority before printing. Changing a label after printing is the most common reason labels end up in the bin.

Common mistakes

• Counting the bottle and forgetting the cap, band and bag. Pennies add up: in the example, everything except the bottle and cap comes to $0.40.
• Using the case price when you actually buy by the dozen. Use the price you really pay.
• Ignoring spoiled pieces. Crooked labels, chipped jars, lids that will not seal.
• One packaging cost for every channel. If delivery needs a sealed bag and the market stall does not, those are two numbers.

Do it with the calculator

In the food cost calculator, add up the cost per unit of each packaging item and enter the total in "Packaging and label per unit"; it adds it to your recipe's loaded cost.
