Most packaging websites hide their prices behind a quote form. We publish ours, so this guide explains exactly what drives the cost of a custom printed box and gives you realistic per-unit ranges you can budget against today.
The five things that set your price
Every custom box quote, from any manufacturer, is built from the same five inputs. Understand them and you can predict your price before you ask for it.
1. Board (the material)
Board is usually 40 to 60 percent of the unit cost. It is priced by area, so a bigger box costs more even before printing. Rough 2026 costs per square inch of blank, including die-cutting and gluing waste:
| Board | Typical use | Relative cost |
|---|---|---|
| 14 pt SBS paperboard | Light retail cartons, cosmetics | 1.0x |
| 18 pt SBS paperboard | Most folding cartons | 1.2x |
| 24 pt SBS paperboard | Heavy or premium cartons | 1.5x |
| E-flute corrugated | Mailer boxes | 1.6x |
| B-flute corrugated | Shipping boxes | 1.9x |
| BC double-wall corrugated | Heavy-duty shipping | 2.8x |
| 2 mm rigid greyboard, wrapped | Luxury set-up boxes | 5.5x |
Rigid boxes are expensive because they are assembled by hand from several parts: a chipboard base, a printed wrap, sometimes a neck and an insert. Folding cartons come off a die-cutter and gluer in one piece.
2. Printing method
Below roughly 500 units, digital printing wins: there are no plates, so short runs are cheap to set up. Above 500 units, offset printing takes over. Plates cost money once, but each sheet is far cheaper, and the colour is more consistent. Box Sense switches automatically and never charges for plates or dies.
Adding print to the inside of the box roughly doubles the print cost, because the sheet goes through the press twice. It is still one of the highest-impact upgrades for e-commerce mailers.
3. Finishing
Finishing is where quotes diverge most between suppliers. Typical adders per unit at 1,000 pieces:
- Aqueous coating: $0.02 to $0.04
- Matte or gloss lamination: $0.08 to $0.12
- Soft-touch lamination: $0.14 to $0.20
- Spot UV: $0.10 to $0.15 plus a one-time screen
- Foil stamping: $0.15 to $0.25 plus a one-time die
- Embossing or debossing: $0.12 to $0.18 plus a one-time die
- Die-cut window with film: $0.09 to $0.14
- Paperboard insert: $0.18 to $0.40 depending on complexity
4. Quantity
Setup costs (proofing, make-ready, press wash-up, die-cutter setup) are fixed. Spread over more boxes, they shrink. This is why a mailer that costs about $4.00 at 10 units can cost $1.17 at 1,000 and $0.75 at 10,000. The curve is steep up to about 500 units and then flattens.
5. Size
Because board is priced by area, doubling each dimension roughly quadruples the material cost. A 4 x 4 x 4 in carton uses about 130 sq in of board; an 8 x 8 x 8 in carton uses about 520 sq in. Right-sizing your box is the single cheapest way to cut cost, and it lowers freight too.

| Product | 100 units | 500 units | 1,000 units | 5,000 units |
|---|---|---|---|---|
| Straight tuck end carton, 18 pt, 3 x 2 x 5 in | $1.15 | $0.61 | $0.51 | $0.36 |
| Mailer box, E-flute, 8 x 6 x 3 in | $2.64 | $1.41 | $1.17 | $0.83 |

| Window box, 18 pt, 4 x 4 x 4 in | $1.66 | $0.89 | $0.74 | $0.53 |
| Rigid magnetic box, 8 x 6 x 3 in | $9.10 | $4.85 | $4.05 | $2.87 |
The hidden fees to ask about
When comparing quotes, ask each supplier these questions in writing:
- Are die and plate charges included? Many quotes add $75 to $300 after you accept.
- Is shipping included, and to where? "Free shipping" often applies only above a minimum or only to one warehouse.
- Is the sample free, and is it credited? Samples can cost $30 to $100.
- How many revision rounds are free? One is common; Box Sense includes two.
- What is the over-run tolerance? Offset runs typically deliver plus or minus 5 percent and bill accordingly.
How to lower your unit cost without hurting quality
- Consolidate SKUs on one press run. Two designs in one order share the setup.
- Order the next quantity break. The jump from 400 to 500 units often costs almost nothing extra.
- Choose aqueous coating over lamination unless you need the feel of soft-touch.
- Print inside in one colour instead of full colour. It still delivers the unboxing surprise.
- Right-size the box. Send us the product; our engineers will minimise the blank.
