Pricing is the single decision that most determines whether a store survives. It is also the one beginners spend the least time on — usually matching the first competitor they can find, then adjusting later when something feels off. This guide walks through a more deliberate approach.
None of the numbers below are prescriptive. Every category has its own dynamics. What matters is the framework: know your costs, understand margin versus markup, price for the business you intend to run, and adjust with reason rather than reaction.

Margin and markup are not the same thing
This is the single most common source of pricing confusion. The two terms sound interchangeable. They are not, and mixing them up produces prices that quietly lose money.
Markup is the percentage added on top of what the product cost you.
Margin is the percentage of the final selling price that is profit.
Example — a product that costs $10:
| Markup | Selling price | Profit | Margin |
|---|---|---|---|
| 25% | $12.50 | $2.50 | 20% |
| 50% | $15.00 | $5.00 | 33% |
| 100% | $20.00 | $10.00 | 50% |
| 200% | $30.00 | $20.00 | 67% |
A 50% markup is a 33% margin. A 100% markup is a 50% margin. The higher the markup, the more the two numbers diverge.
Why this matters: platform fees are almost always quoted as a percentage of the sale price. Payment processing, referral fees, and commissions all come off the revenue — not off the cost. If you price using markup but budget using margin, the two calculations produce different answers, and the business math doesn't reconcile.
Worked example
You source a product for $8. You want to "make 50%."
If you mean 50% markup: price is $12.00. After a 15% platform fee ($1.80) and $0.60 in processing, net is $9.60. Profit = $1.60 (13% margin).
If you mean 50% margin: price is $16.00. After the same fees, net is $12.80. Profit = $4.80 (30% margin).
Same intent, same wording, two very different businesses.
The full cost stack, in order
Before setting a price, model every cost that comes out of a sale. There are six common layers. Miss any one and the price looks fine on paper but loses money in practice.
| Layer | Typical impact | How it varies |
|---|---|---|
| Product cost | $3–$30 per unit | Depends entirely on category and volume |
| Freight and duties | 15–40% of product cost (if imported) | Weight, distance, tariff class |
| Platform fees | 6–15% of sale price | Marketplace, category, seller tier |
| Payment processing | 2.5–4% + fixed fee | Country, payment method |
| Fulfillment | $3–$10 per order | FBA, 3PL, or self-fulfilled |
| Returns (amortized) | 2–10% of revenue | Category return rate |
Advertising is a seventh layer but is usually treated separately because it varies so widely. A product with a $2.80 margin and $6 of ad spend per sale is a losing business, even though the fee math alone looks fine.
Why "match the competitor" is a trap
The most common pricing error is opening three competitor listings, averaging their prices, and setting your own one cent below. This approach fails for five reasons:
- You don't know their cost structure. A competitor selling at $22 may be sourcing at $4 with volume discounts you don't have. Matching their price could mean selling at a loss.
- You don't know what they're including. Free shipping, bundled extras, faster fulfillment — each of those represents a real cost that may or may not be reflected in the price.
- You don't know their business model. Some sellers use one product as a loss leader to drive traffic to higher-margin items. Their price on that item tells you nothing about what yours should be.
- You don't know their stage. A seller clearing old inventory may temporarily price below cost. A new seller testing the market may be pricing artificially low to learn.
- You don't know their reviews. A listing with 500 reviews and Prime shipping can command a higher price than a new listing with neither. The price gap is often justified by trust, not by margin.
Competitors are useful for a different reason: they show you the upper and lower bounds of what the market will accept. They are a sanity check on your calculated price, not a substitute for calculating one.
A pricing framework that works
Here is a sequence that produces defensible prices. It takes about 20 minutes per product.
Step 1 — Total landed cost
Product cost plus freight plus duties plus any inbound handling. This is the number everything else builds on.
Step 2 — Add platform and payment fees
Calculate what percentage of the sale price goes to the platform and to payment processing. Do not estimate — use the current rates for your specific platform, category, and account tier.
Step 3 — Add fulfillment and returns
If you fulfill yourself, this is the actual carrier cost plus packaging. If you use a third-party service, this is the fee. Add a realistic return rate — most categories run 3–8%.
Step 4 — Set a target net margin
Different businesses target different numbers. A reasonable range for physical products sold through marketplaces is 15–25% net profit. Digital products often run higher. Commodity physical products may run lower. The target is not aspirational — it is the floor below which the business does not work.
Step 5 — Solve for price
Working backwards: the sale price must cover all costs and leave the target margin on top. A calculator handles this faster than manual math because the platform fee depends on the price, which is what you're solving for.
Step 6 — Sanity-check against the market
Compare the calculated price to competitor listings. If it's wildly above, either the product needs repositioning (bundle, niche, upgrade) or the margin target needs review. If it's wildly below, you may be underpricing relative to perceived value.
Worked pricing example
Product cost $8, freight $1.50, target platform 15%, processing ~3%, fulfillment $4.00, return rate 5%, target net margin 20%.
| Line | Amount |
|---|---|
| Landed cost (product + freight) | $9.50 |
| Fulfillment per order | $4.00 |
| Returns allowance (5% of sale) | varies |
| Platform fee (15% of sale) | varies |
| Processing (3% of sale) | varies |
| Target net margin | 20% of sale |
Solving this yields a price around $20.50. Below that, the target margin is not met. Above that, additional margin accrues.
At $20.50, the fee stack is roughly:
| Item | Amount |
|---|---|
| Sale price | $20.50 |
| Platform fee (15%) | –$3.08 |
| Processing (3%) | –$0.62 |
| Fulfillment | –$4.00 |
| Returns allowance (5%) | –$1.03 |
| Landed cost | –$9.50 |
| Net profit | $2.27 |
$2.27 on a $20.50 sale is about 11% net. To hit the 20% target ($4.10), the price would need to rise to about $22.50.
This is why the sequence matters. Without the target margin, the price looks fine. With it, the gap becomes visible.
Pricing to a market segment
Not all pricing is cost-plus. Some sellers price to a market segment instead. This works when the product has a clear positioning (premium, mid-market, budget) and the cost structure supports it.
- Budget positioning: price at the low end, compete on volume, keep costs lean. Works when you have a real cost advantage.
- Mid-market: price in the middle, compete on reliability and reviews. The most common position and the most competitive.
- Premium: price above the market average, justify with presentation, packaging, service, or a specific benefit. Requires margin to support higher ad spend.
None of these positions is inherently better. The mistake is trying to be premium with budget costs, or budget with premium overheads. The position must match the economics.
Positioning consistency
A product with premium packaging, custom inserts, and a branded unboxing experience costs money. If the price is set at budget level, those extras erode margin without producing the trust they were designed to create.
Positioning is not marketing — it is a pricing constraint.
When to raise prices
Most new sellers underprice initially, then discover they need to raise prices once ad spend and returns kick in. Three signals indicate it's time:
- Conversion is strong but profit is thin. If the product sells well and the margin is under the target, the price is too low.
- Ad costs are rising. Customer acquisition cost rises over time in most categories. A price that worked at launch may not cover current ads.
- Supplier or shipping costs have moved. A 5% increase in landed cost usually needs at least a 3% price increase to preserve margin.
Raising prices does not require a public announcement unless you've made a commitment not to. It does require that you check the effect on conversion over the following two weeks and adjust if the change is too large for the market to absorb.
What to do next
Run the numbers on your product. Use the pricing calculator to solve for the price that hits your target margin after every cost. Compare the result to the market. If the two align, set the price and move on. If they don't, revisit the target margin, reposition the product, or reconsider the sourcing.
Pricing is iterative. The right price today may not be the right price in six months. What matters is that the framework stays consistent, so every change is a deliberate one.
