Ask a founder what one unit of their product earns and you will usually get the marketplace number: sale price minus fees minus cost, done. That is one channel. The same unit sold to a retailer at half the price has a completely different set of costs, and it often ends up earning a similar amount with far less effort per unit. Unit economics is the discipline of working out what a single unit earns in each channel after every cost that unit causes, and it is the only fair way to compare Amazon with wholesale.
This guide builds the two models side by side with round numbers, shows where the comparison usually goes wrong, and gives you a way to decide how much of your volume belongs in each channel.
What unit economics means for a product brand
Unit economics is revenue per unit minus all the costs a single unit triggers, in a specific channel. It is contribution margin per unit, viewed channel by channel. The reason to do it per channel is that the costs are so different:
- On a marketplace, a unit carries referral fees, fulfillment, storage, advertising and a return rate, and it sells one at a time.
- In wholesale, a unit sells at a lower price but carries almost none of those costs, and it ships in cases with dozens of other units.
Both start from the same landed cost. Everything after that diverges, which is why comparing the two on gross margin alone is meaningless; gross margin vs net margin explains that trap.
The marketplace model
Take a product with a landed cost of 7 dollars that sells for 25 dollars on a marketplace. Per unit, working down:
- Sale price: 25.00
- Referral fee, a share of the sale price: about 3.75
- Fulfillment fee for pick, pack and ship: about 5.00
- Monthly storage allocated per unit: about 0.40
- Advertising, total ad spend divided by all units sold, not just ad-attributed ones: about 3.00
- Returns and refund losses, as a per-unit allowance: about 0.60
- Landed cost: 7.00
Contribution per unit: about 5.25 dollars, roughly 21 percent of the sale price.
The fee amounts here are illustrative; yours depend on size, weight, category and how hard you push ads. The structure is the point: most of the 25 dollars goes to costs that scale with every single unit, and advertising is the line that quietly decides whether the channel makes money.
The wholesale model
Same product, same 7 dollar landed cost, sold to a retailer at 12.50 dollars, half of the 25 dollar retail price. A typical order is a case of 24. Per unit:
- Wholesale price: 12.50
- Outbound freight, if you pay it, spread across the case: about 0.50
- Packing materials and labor, per unit on a case order: about 0.25
- Payment processing or early-payment discount allowance: about 0.25
- Samples, allowances and chargebacks, as a per-unit reserve: about 0.25
- Landed cost: 7.00
Contribution per unit: about 4.25 dollars, roughly 34 percent of the wholesale price.
The marketplace unit earns about a dollar more. That is the number most founders stop at, and it is why they conclude wholesale is not worth it. Keep going.
The comparison that actually matters
Three adjustments change the picture.
Effort per unit. The marketplace unit needed a listing, ongoing advertising management, customer service and a return process, one unit at a time. The wholesale unit was one twenty-fourth of a single order with one invoice and one shipping label. If you value your own time at all, contribution per hour of work favors wholesale by a wide margin once orders reach case quantity.
Cash and risk. Advertising is paid in advance and is never guaranteed to work. A wholesale purchase order is a commitment from a buyer before you ship. Wholesale can tie up cash in net terms, but the demand is contracted rather than hoped for.
Volume and ceiling. A marketplace listing has a ceiling set by search demand and ad costs, and pushing past it usually means paying more per unit in ads, which lowers the contribution. A wholesale account reorders on a cadence, and adding accounts adds volume without raising the per-unit cost. The channel decision in detail is covered in retail vs wholesale margins.
Put the numbers together for a month. Say the marketplace moves 1,000 units at 5.25 contribution, which is 5,250 dollars, after a serious amount of daily attention. Twenty wholesale accounts reordering a case each moves 480 units at 4.25 contribution, which is 2,040 dollars, from twenty invoices. Wholesale is smaller today. It is also a channel where the fortieth account costs the same to serve as the twentieth, and where nobody can raise your fees overnight.
Running the numbers for your own product
The free wholesale margin calculator does this comparison for your actual product: enter landed cost, marketplace price and fees, and a wholesale price and order size, and it shows the profit on one wholesale order next to a month of marketplace sales. A few rules for filling it in honestly:
- Use true landed cost. Freight and duties included. The factory quote is not your cost.
- Charge all advertising to the marketplace units. Not only the sales the ad platform claims, because the rest of your marketplace sales depend on that spend too.
- Include a return and damage allowance on both sides. Wholesale has fewer returns but does have chargebacks and samples.
- Cost your own time. Even at a modest hourly figure, it changes the answer.
- Model a realistic wholesale order size. A case of 24 to a boutique and a pallet to a distributor have different freight and handling per unit.
What the models tell you to change
Once the two models sit side by side, the levers become obvious:
- If marketplace contribution is thin, the usual cause is advertising. Wholesale gives you volume that does not require it.
- If wholesale contribution is thin, the usual cause is price or freight. Raising the wholesale price a dollar, or moving freight to the buyer, changes the model far more than any other line. Amazon FBA fees vs wholesale margin walks through these levers one at a time.
- If both are thin, the problem is landed cost, and no channel strategy fixes it.
- If wholesale contribution per order is small but positive, the fix is order size and minimums, not price; contribution margin for product brands shows how to judge an individual order.
Common mistakes in the comparison
- Comparing on gross margin. Sixty percent versus thirty-five percent looks decisive and means nothing until selling costs come off.
- Leaving advertising out of the marketplace model. It is the largest variable cost for many brands and the easiest to forget because it is paid monthly, not per unit.
- Assuming wholesale is free to serve. Freight, samples, chargebacks and net-terms financing are real. Small, but real.
- Pricing wholesale to protect the marketplace number. If the wholesale price is set so low that the model never works, the comparison was rigged before it started.
- Ignoring the time axis. A unit that took ten minutes of your attention and a unit that took ten seconds did not earn the same amount, even if the contribution matches.
The short version
Unit economics means working out what one unit earns in each channel after every cost that unit causes. On a marketplace, fees and advertising eat most of a high sticker price. In wholesale, a lower price carries almost no selling cost and ships in cases. The per-unit contribution is often closer than the gross margins suggest, and once you add effort, cash risk and the volume ceiling, wholesale frequently earns its place as a second channel rather than a lesser one.
The model only pays off with buyers to sell to. WholesalePilot finds the distributors, wholesalers and retail buyers that fit your product, verifies their emails, sends outreach in your name and books the calls, so the wholesale side of your unit economics gets real volume behind it.
A unit that sells itself twenty-four at a time is worth more than its margin says.
