The wholesale price on an invoice is not your cost. It is the starting point. Between the wholesale price and what a unit actually costs you to put on the shelf, there are excise duties, freight, shrinkage, and compliance overhead — and most of these are predictable and calculable before you place an order. This guide gives you the complete cost formula, the excise calculation method for Canadian vaping products, a category-by-category comparison, and the margin arithmetic you need to set retail prices with confidence.
Part 1: The True Cost Formula
Every unit that reaches your shelf has passed through at least four cost layers beyond the wholesale price. Ignoring any one of them produces a margin calculation that is wrong in your favour — until it is not.
| Cost Component | What It Is | How to Estimate It |
|---|---|---|
| Wholesale price | The per-unit price from your distributor, before any other charges | From your wholesale invoice. This is your baseline. |
| Federal excise duty | A federal duty on vaping products calculated by liquid volume (mL). Applies to all vaping products sold in Canada. | For product sourced from a licensed Canadian distributor, excise duty is included in the wholesale price. See Part 2 for the calculation if you are verifying independently. |
| Freight | Shipping cost per order, allocated across units received |
Freight Cost ÷ Total Units Received. On a $15 freight charge across 100 units, that is $0.15 per unit. Above Arctic's $1,000 free shipping threshold, this drops to $0. |
| Shrinkage | Inventory loss from theft, damage, or unsellable product | Typical vape retail shrinkage runs 1–3% of inventory value. Apply as a per-unit cost: Wholesale Price × Shrinkage Rate. On a $10 unit at 2% shrinkage, that is $0.20. |
| Compliance overhead | Your share of the cost of maintaining SVS registration, CPA accountant fees, staff training, and regulatory compliance activities | Total annual compliance cost ÷ total annual units sold. For a store spending $2,000/year on compliance and selling 5,000 units, that is $0.40 per unit. |
True Cost = Wholesale Price + (Freight ÷ Units) + (Wholesale Price × Shrinkage Rate) + (Annual Compliance Cost ÷ Annual Units Sold)Excise duty is included in the wholesale price when sourcing from a licensed Canadian distributor — it does not need to be added separately.
Part 2: How the Canadian Excise Duty Works
Understanding excise duty is important for two reasons: it explains a portion of why vape wholesale prices are higher in Canada than in unregulated markets, and it tells you what to look for when verifying that a supplier's pricing reflects compliant, duty-paid product.
Under Canada's vaping duty framework, the federal excise duty on vaping products is charged at a flat rate per millilitre of vaping substance. As of 2026, the rate is:
| Tier | Rate (Federal) | Applies To |
|---|---|---|
| First 10 mL | $1.12 per 2 mL (i.e. $5.60 for first 10 mL) | All vaping products containing vaping substance |
| Each additional 10 mL (or part thereof) | $1.12 per 2 mL ($5.60 per 10 mL) | Amounts above the first 10 mL |
In addition, participating provinces (including Ontario) apply a coordinated provincial duty of equal value, effectively doubling the excise cost. For Ontario, the combined federal + provincial duty rate is $1.12 per mL on the first 10 mL and each subsequent 10 mL.
Worked example — a typical 14 mL disposable (e.g. a high-puff-count device like Lost Mary OS50000 or similar):
- First 10 mL: 10 × $0.56 = $5.60 (federal) + $5.60 (Ontario) = $11.20
- Remaining 4 mL: rounds up to next 2 mL increment — 4 mL = 2 × $0.56 = $1.12 (federal) + $1.12 (Ontario) = $2.24
- Total excise on one 14 mL disposable: approximately $13.44
Verify the actual liquid volume for each specific SKU — manufacturers do not always make this easy to find, but it will be on the product specification sheet or Health Canada's product registry. The exact mL fill determines your excise calculation, so rounding up to the nearest 2 mL as required by the duty framework is important for accuracy.
This excise cost is embedded in the wholesale price when you buy from a licensed Canadian distributor. A wholesale price that appears significantly lower than comparable licensed distributor pricing is almost certainly not including excise duty — which means either the product is unstamped, or the supplier is misrepresenting the compliance status. See our guide on grey market vapes for the retailer risk implications.
Part 3: True Cost by Category
Different product categories have materially different cost structures. Understanding these differences lets you evaluate margin realistically before committing to a buying decision.
| Category | Typical Wholesale Range (CAD) | Excise Component | Margin Characteristics |
|---|---|---|---|
|
Disposable vapes (Lost Mary, DOJO, ALLO) |
$12–$22 per unit (single) | High — excise on 10–20 mL fills is $11–$22+ per unit (federal + Ontario) | Excise is the dominant non-wholesale cost. Retail markup typically 30–50% over wholesale. High velocity offsets lower per-unit margin. |
|
Closed pod systems (STLTH, Level X) |
$8–$18 per pack | Moderate — pod volumes are typically 2–4 mL each, excise per pack varies by number of pods | Repeat purchase category. Loyalty-driven. Margin per pack is moderate but lifetime customer value is high. |
|
Open pod kits / devices (Vaporesso, Uwell) |
$25–$60 per device | Low — devices contain no vaping substance, excise applies only to pre-filled pods or e-liquid sold separately | Higher absolute margin per unit. Lower excise burden. Drives ancillary e-liquid and pod sales — evaluate device margin alongside the recurring purchase it generates. |
|
Salt nic e-liquid (KAPOW SALT, SUAVAE) |
$10–$18 per 30 mL bottle | High relative to price — excise on 30 mL is approximately $33.60 (federal + Ontario), often exceeding the wholesale price of the liquid itself | Excise-heavy category. Retail pricing must account for full excise pass-through. Smaller customer segment than disposables but strong loyalty. |
|
Freebase e-liquid (Flavour Beast, LEMON DROP) |
$10–$20 per 60–100 mL bottle | Very high — excise on a 100 mL bottle is approximately $112 (federal + Ontario combined) | Excise dominates the cost structure at large volumes. Retail pricing must reflect this. Sub-ohm customer segment; lower velocity than disposables for most SVS stores. |
Part 4: Calculating True Margin and Setting Retail Prices
True Gross Margin Formula
Once you have your true cost per unit, calculating actual gross margin is straightforward:
Example: a typical high-puff-count disposable (e.g. Lost Mary OS50000) retailing at $34.99
Wholesale: $18.00 (illustrative — actual pricing varies; apply for a wholesale account to see current rates) | Freight allocation: $0.15 | Shrinkage (2%): $0.36 | Compliance: $0.40
True Cost: $18.91
Gross Margin: ($34.99 − $18.91) ÷ $34.99 × 100 = 46%
Reverse-Engineering a Retail Price From Your Margin Target
If you know your true cost and have a target gross margin, you can calculate the minimum retail price required to hit that margin:
Example: True cost of $18.91, target margin of 40%
Minimum retail = $18.91 ÷ (1 − 0.40) = $18.91 ÷ 0.60 = $31.52
Selling below this price means you are below your margin target, even if you appear to be making money on the invoice price alone.
Common Margin Mistakes
- Marking up from wholesale price only. A 40% markup on an illustrative $18.00 wholesale unit gives you $25.20 retail. That looks like a $7.20 margin. Subtract freight ($0.15), shrinkage ($0.36), and compliance ($0.40) and your true margin drops to $6.29 — a real gross margin of 25%, not 40%. Pricing from invoice cost without adding the other components systematically underprices your products.
- Treating CTN pricing as per-unit cost. A carton of 5 units at $80 is $16 per unit — but only if all 5 sell. If one unit is damaged or stolen, your effective cost on the remaining 4 rises to $20 each. At a $25 retail price, that means one unit of shrinkage turns a 36% margin category into a 20% margin category on that carton. Build a 2% shrinkage assumption into your per-unit cost before committing to a retail price, not after.
- Ignoring seasonal velocity changes. A product with a 90% STR in summer and a 55% STR in winter does not cost the same to carry in both periods. In winter, you are holding that inventory for nearly twice as long before it sells — which ties up capital, increases the risk of dead stock, and effectively raises your per-unit cost through the opportunity cost of that capital. A product that needs a 35% margin to be worth stocking in summer may need a 40% margin target in winter to deliver the same return on capital.
Part 5: Using the $1,000 Free Shipping Threshold Strategically
Freight cost is one of the more controllable components of your true cost calculation. Arctic Distributions offers free shipping on orders above $1,000 CAD — which means your freight cost per unit drops to zero on orders that clear this threshold. The question is how to use this threshold intelligently rather than simply ordering $1,000 worth of inventory to unlock free shipping regardless of what you actually need.
Calculate Your Freight Break-Even Point
If your typical shipping cost is $20 on a $600 order, your freight allocation per unit on that order is $20 ÷ 60 units = $0.33 per unit. On a $1,000 order with free shipping, that freight cost is $0. The question is whether it makes sense to top up an order to reach $1,000 — and the answer depends on what you are adding.
- Top up with star SKUs only. If you need to add $400 to reach the free shipping threshold, use that $400 on high-velocity products you know will sell — not on slow movers you are buying opportunistically. Adding $400 of product with a 30% STR to save $20 in freight costs creates more dead stock risk than the freight saving is worth.
- Use the threshold to test new SKUs at low risk. If you are already at $900 and want to reach $1,000, a small quantity of a new brand or flavour is a low-cost way to validate demand before committing to a larger order — the freight saving partially offsets the risk of the test order.
- Do not over-order slow movers to hit the threshold. Freight is a real cost, but so is dead stock. $20 in saved freight against $100 in stranded inventory is a net loss.
Applying This to Your Margin Calculation
For orders above $1,000, remove freight from your true cost calculation entirely. Your revised formula becomes:
On the same example above: $18.00 + $0.36 + $0.40 = $18.76 (vs. $18.91 with freight)
Gross margin at $34.99 retail: ($34.99 − $18.76) ÷ $34.99 × 100 = 46.4%
The difference is small on a per-unit basis but compounds meaningfully across a full order. On 100 units, eliminating $0.15 in freight per unit saves $15 — which is effectively the same as negotiating $15 off your invoice.
