The verdict in three sentences
Packaging is the line everyone underestimates: too weak, it generates 3 to 8 % breakage and costly returns; too big, it inflates volumetric cost by 15 to 30 %. Right-sizing targets a packaging cost of 2 to 5 % of order value, with padding focused on fragile items. Done well, it cuts breakage by 50 to 70 % and even lifts repeat purchase by 5 to 10 % thanks to a tidy box.
Under-packing versus right-sizing
Two opposite mistakes are expensive. Under-packing saves a few cents per parcel but pays in breakage, returns and negative reviews. Over-packing (big box, too much filler) reassures on protection but blows up the volumetric cost billed by the carrier.
Right-sizing: a box matched to the product, padding targeted where it is fragile, no more no less.
| Criterion | Under-packing | Right-sizing |
|---|---|---|
| Breakage / return rate | 3 to 8 % | Under 2 % |
| Packaging cost / order | Very low | 2 to 5 % of value |
| Volumetric cost (shipping) | Baseline | -15 to 30 % vs oversized |
| Breakage returns | High | -50 to 70 % (targeted padding) |
| Effect on repeat | Neutral to negative | +5 to 10 % (tidy box) |
| Bulk buying | No | -20 to 40 % on materials |
The real cost of breakage
A breakage return costs more than the product: it costs the return leg, the replacement, the second shipment, and often the negative review. On a 15 000 item, a breakage return can cost 20 000 to 25 000 once everything is counted. At 3-8 % breakage, the bill climbs fast.
| Line (order at 15 000) | Under-packing | Right-sizing |
|---|---|---|
| Packaging cost | 150 | 450 to 700 |
| Breakage (weighted probability) | 900 to 1 400 | 200 |
| Volumetric shipping cost | High | Optimized |
| Returns / support | 600 to 1 000 | 150 |
| Estimated total cost | 1 650 to 2 550 | 800 to 1 050 |
Spending 300 to 500 more on suitable packaging saves two to three times more in avoided breakage and support.
Levers to lower cost without sacrificing protection
Three axes. Bulk buying of boxes and filler cuts material price by 20 to 40 %. Targeted padding (bubble or foam only around fragile zones) cuts breakage by 50 to 70 % without over-packing. Finally, a tidy branded box, without excess, raises perceived value and repeat purchase by 5 to 10 %; eco/reusable options support premium positioning.
Mini case study
Akosua sells tableware and decor items in Accra, 220 orders a month, average basket 16 000 (local currency). With minimal packaging, her breakage rate is 7 %: 15 broken parcels a month. Full cost per breakage (product + return leg + replacement): about 22 000, i.e. 330 000/month.

She moves to targeted padding (foam around fragile pieces) at +400 per parcel, i.e. 88 000/month of extra material cost. Breakage drops to 2 %: 4 parcels instead of 15, breakage cost 88 000 instead of 330 000. Net saving: 330 000 - 88 000 - 88 000 = 154 000/month, plus fewer negative reviews.
FAQ
What packaging budget should I target?
Between 2 and 5 % of order value in 2026. Below that, you risk breakage; above it, you erode margin with no real protection gain.
What is volumetric cost?
Carriers often bill the higher of actual weight and volumetric weight. A box too big makes you pay for empty space: up to 15 to 30 % of avoidable surcharge.
Is a branded box worth it?
Yes if it stays sober. It raises perceived value and repeat purchase by 5 to 10 %, for a modest surcharge. Avoid marketing over-packing that inflates volume.
How do I cut breakage fastest?
Targeted padding on fragile zones cuts breakage by 50 to 70 %. It is the most cost-effective lever before investing in pricier materials.
Is bulk buying worth it for a small store?
From 150 to 200 parcels/month, bulk buying cuts materials by 20 to 40 %. Pooling with other sellers speeds up the break-even point.
