In a typical ecommerce supply chain, wholesale price is the amount a supplier charges a business buying goods for resale. Retail price is the amount charged to the end customer. The two prices belong to different transactions in the distribution chain, and each seller has its own costs and margin. A retailer’s purchase price is therefore a starting point for pricing, not a measure of everything it costs to sell the product.
Follow one hypothetical bottle from supplier to retailer to customer, and the distinction becomes clearer: a $30 wholesale price can become a $32 product cost for the retailer before it sells for $50.
Key takeaways
- Wholesale and retail describe who buys the product and why. Order size alone does not define the channel.
- Gross margin divides gross profit by selling price; markup divides it by cost.
- In the hypothetical example below, a 10% retail discount cuts gross profit per unit by 27.78% when product cost stays unchanged.
What is wholesale price, and what is retail price?
Wholesale and retail prices apply to different transactions. The same business can sell through both channels, but the buyer’s purpose and the terms of each sale differ.
What is wholesale price?
In a typical ecommerce supply chain, wholesale price is the price a supplier charges a business buying goods for resale. The supplier might manufacture the product or distribute goods made by another company. The buyer then sells those goods onward.
A wholesale quote usually states a price per unit alongside order conditions. Those conditions can include a minimum quantity, pack sizes, payment terms and who pays for delivery. A lower unit price might depend on buying a larger quantity. Check the conditions before treating a quoted price as your purchase cost.
What is retail price?
Retail price is the price charged to the final buyer for their own use. It can be the regular selling price or a temporary sale price. A manufacturer can also suggest a retail price, but that recommendation does not establish what every customer will actually pay.
Retail prices are commonly higher than wholesale prices for the same item because the retailer needs room to cover its product cost and selling expenses. There is no fixed gap between the two prices. A customer buying a large pack for personal use is still making a retail purchase.
One product, two businesses: the full price example
The supplier’s selling price becomes the retailer’s purchase price. Each business then calculates gross profit using its own selling price and its own cost of goods sold, or COGS.
Hypothetical example: A supplier sells a reusable bottle to a retailer, which sells it to a customer. All amounts are USD, excluding taxes. These are invented teaching figures, not industry benchmarks or customer results. The calculations follow the same unit through both completed sales, with no returns.
The supplier’s product cost is $20 per unit. The retailer pays $30 for the bottle plus $2 per unit in allocated inbound delivery to the store. For this simplified example, those two items make up the retailer’s $32 product cost, recognized as COGS when the unit sells.
| Measure | Supplier → retailer | Retailer → customer |
|---|---|---|
| Product cost per unit | $20.00 | $32.00 ($30 purchase + $2 inbound delivery) |
| Selling price per unit | $30.00 wholesale | $50.00 retail |
| Gross profit per unit | $10.00 | $18.00 |
| Gross margin | 33.33% | 36.00% |
| Markup on product cost | 50.00% | 56.25% |
The supplier earns $10 in gross profit on a $30 sale. Dividing $10 by the selling price gives a 33.33% gross margin; dividing it by the $20 cost gives a 50% markup.
The retailer earns $18 in gross profit on a $50 sale. Its gross margin is $18 ÷ $50 = 36%. Its markup on the $32 product cost is $18 ÷ $32 = 56.25%.
The $20 gap between the wholesale and retail prices is not the retailer’s gross profit: the $2 inbound delivery cost also belongs in this example’s cost base. Nor can you add the supplier’s 33.33% margin to the retailer’s 36% margin. Those percentages use different businesses’ sales revenue as their denominators.
The retailer’s $18 is not net profit. Payment processing, advertising, store operating expenses and any later returns are outside this simplified calculation. Their effects still need to be reflected when assessing the business’s final result. They have not been silently folded into the $32 COGS figure.
Wholesale vs retail price formulas: margin and markup
The same formulas work at either stage of the sale. What changes is whose cost and whose selling price you use.
Let P mean selling price per unit and C mean that seller’s COGS per unit. Use the same product, currency and tax basis throughout.
Gross profit per unit = P − C Gross margin (%) = ((P − C) / P) × 100 Markup on cost (%) = ((P − C) / C) × 100
Margin asks how much of the selling price remains after product cost. Markup asks how much has been added relative to that cost. The dollar difference is the same; the denominator changes.
Price for a target gross margin
To calculate a selling price for a target gross margin m, enter the margin as a decimal: 40% becomes 0.40. The target must be below 100% when cost is positive.
Price for target gross margin = C / (1 − m) With C = $32 and m = 0.40: Price = $32 / 0.60 = $53.333…
That is approximately $53.33. If the margin must be at least 40%, a price rounded to cents needs to be $53.34. At $53.33, the actual gross margin is slightly below 40%, even though a rounded percentage display might show 40.00%.
Price for a target markup
To calculate a selling price for markup u, multiply the cost by one plus the markup, again expressed as a decimal.
Price for markup = C × (1 + u) With C = $32 and u = 0.40: Price = $32 × 1.40 = $44.80
The resulting gross profit is $12.80, and the gross margin is $12.80 ÷ $44.80, or about 28.57%. A 40% markup therefore produces a very different price from a 40% gross margin.
The cost base matters just as much as the percentage. If W means only the $30 wholesale purchase price, W / (1 − m) omits the retailer’s $2 inbound delivery cost. For this example, the correct calculation is (W + $2) / (1 − m). Use C / (1 − m) when C includes the full product cost you have defined.
What a 10% retail discount does to gross profit
A percentage discount on the selling price can cause a much larger percentage decline in gross profit. The discount reduces revenue while the cost of the already purchased product stays unchanged.
In the same hypothetical example, the retailer reduces its $50 selling price by 10%. The new price is $50 × 0.90 = $45, while product cost remains $32.
| Measure | Regular price | After a 10% discount |
|---|---|---|
| Selling price per unit | $50.00 | $45.00 |
| Product cost per unit | $32.00 | $32.00 |
| Gross profit per unit | $18.00 | $13.00 |
| Gross margin | 36.00% | 28.89% |
The gross profit decline is:
($18 − $13) / $18 × 100 ≈ 27.78%
Gross margin also falls by about 7.11 percentage points, from 36% to 28.89%. That is a different measurement from the percentage decline in gross profit per unit.
This calculation does not predict whether the discount will attract enough additional sales to improve total profit. It shows the effect on each unit sold under the stated assumptions. When several price reductions apply, distinguish the advertised starting price from the amount charged; the separate guide to list price and net price covers that distinction.
Why doubling wholesale price is only a shortcut
Keystone pricing sets retail price at twice the wholesale purchase price. It is a starting heuristic, not a rule that fits every product or guarantees a profit.
For the bottle, doubling the $30 wholesale price gives a $60 retail price. That is a 100% markup on the purchase price. It would produce a 50% gross margin only if $30 were the entire product cost.
With the retailer’s actual $32 cost base in this example, gross profit at $60 is $28. Gross margin is therefore $28 ÷ $60, or about 46.67%.
Doubling the invoice price cannot establish whether customers will pay $60, how much a sale costs to acquire or how many units will remain unsold. The multiplier also says nothing about the supplier’s margin, which depends on the supplier’s own costs.
Order quantity, unit cost and total spend are different
A wholesale unit price does not tell you how much cash an order requires. Multiply it by the required quantity, then account for delivery and other applicable charges.
As an order-size extension of the hypothetical bottle example, suppose the supplier requires at least 24 units, sold in increments of six, with a maximum of 120 per order. At $30 each, the minimum goods purchase is $720. With $48 inbound delivery allocated across those 24 bottles, the total outlay is $768, and product cost is still $32 per bottle.
Check whether each minimum or volume-price threshold applies to one variant, a product family or the whole order. Some catalog systems apply rules separately to each variant. Buying two colors does not automatically let you combine their quantities to reach a lower price tier.
A larger order can offer a lower price per unit while requiring more cash overall. Compare both figures and consider how many units you can sell. A quantity discount alone cannot establish that the larger purchase is worthwhile.
Check the calculated price against the business and the market
A target gross margin gives you a candidate price. You still need to assess whether sales at that price can cover the rest of the business’s costs.
For a simplified single-product break-even check:
Break-even units = Fixed costs / (Price per unit − Variable costs per unit)
Use fixed costs for a defined period and include all relevant variable costs per sale, counting each cost once. The denominator is contribution per unit and must be positive. It need not equal the $18 gross profit above: payment fees or other variable selling costs may reduce it. Round a fractional unit result up. This is a planning calculation under stated assumptions, not a sales forecast.
Then use price benchmarking to compare the same product and variant on consistent currency, tax and delivery terms. Competitor prices provide market context, but do not reveal competitors’ costs or prove demand at your proposed price.
If the price needed for your target margin is difficult to sustain, review purchasing terms, product cost and positioning. The guide to ecommerce pricing strategies covers how to choose a broader approach. Keep the underlying calculation explicit: whose sale, which cost base, and whether the target is markup or gross margin.
