Setting a product price is not just about looking at competitors and choosing a similar number.
A profitable selling price needs to cover the product cost, marketplace fees, shipping, packaging, advertising, returns, and taxes while still leaving enough margin for the business to grow.
QUICK ANSWER
To price products for profit, calculate your total cost per order first, add marketplace fees and expected advertising or return costs, choose a target profit margin, compare the result with competitor prices, test the price in the market, and track actual net profit instead of relying only on revenue.
Why Product Pricing Is More Difficult Than It Looks
Many new sellers make one simple calculation:
Selling Price − Product Cost = Profit
That calculation is incomplete.
Your real cost can include:
- Supplier cost
- Marketplace commission
- Payment processing fees
- Shipping
- Packaging
- Advertising
- Returns and refunds
- Storage or fulfillment fees
- Taxes
If you ignore those costs, a product that appears profitable can actually lose money.
Important:
Revenue is not profit. A seller can generate strong sales while losing money on every order.
1. Calculate the Product Cost
Start with the amount you actually pay to obtain one sellable unit.
This can include:
- Wholesale price
- Supplier shipping
- Import cost
- Customs duties
- Inspection costs
- Packaging from the supplier
If you purchase products in bulk, divide the total landed cost by the number of units you can actually sell.
For example:
Total inventory cost: $1,000
Sellable units: 100
Product cost per unit: $10
Tip:
Use landed cost rather than the supplier’s advertised unit price whenever shipping or import expenses are significant.
2. Add Marketplace Fees
Marketplaces normally charge sellers for access to customers and payment infrastructure.
Depending on the platform and category, costs may include:
- Referral or commission fee
- Payment-processing fee
- Listing fee
- Fulfillment fee
- Storage fee
- Optional advertising charges
Do not use a marketplace’s headline fee without checking the fee that applies to your exact category and fulfillment model.
If a marketplace charges a percentage of the selling price, remember that increasing the price also increases the fee.
3. Include Shipping and Packaging
Shipping can destroy a product’s margin if you underestimate it.
Calculate:
- Courier charge
- Box or mailer
- Tape
- Labels
- Protective materials
- Remote-area surcharges
If you offer “free shipping,” the shipping cost is not actually free.
You are paying it, so it needs to be included in the product price.
Warning:
Do not treat shipping as zero just because the customer does not see a separate shipping charge.
4. Estimate Advertising Cost Per Order
If you use paid marketplace advertising, the ad cost should be part of your pricing model.
For example:
If you spend:
$100 on ads
and generate:
10 orders
your advertising cost per order is:
$10
That $10 should be included when you calculate the true profitability of those orders.
Useful metric:
Track both return on ad spend and actual net profit. A high ROAS does not always mean the product is profitable after all other costs.
5. Add a Return and Refund Allowance
Not every order stays completed.
Some products have higher rates of:
- Returns
- Refunds
- Damaged deliveries
- Customer-service compensation
- Reshipping
If you sell 100 orders and historically lose $100 through returns and refunds, the average return cost is:
$1 per order
Building this expected loss into your pricing model gives a more realistic margin.
Tip:
Use your own historical return rate once you have enough orders. Estimates are useful at the beginning, but real store data is better.
6. Choose a Target Profit Margin
After calculating all expected costs, decide how much profit you want to earn from each sale.
A simple margin formula is:
Profit Margin = Net Profit ÷ Selling Price × 100
For example:
Selling price: $50
Total cost: $40
Net profit: $10
Profit margin:
$10 ÷ $50 × 100 = 20%
The correct margin depends on your category, competition, return risk, inventory turnover, and business model.
Important:
Markup and profit margin are not the same thing. Always know which calculation you are using.
7. Compare the Result With Competitor Prices
After calculating your profitable price, compare it with real competing products.
Compare items with the same:
- Quantity
- Size
- Quality
- Brand position
- Shipping
- Delivery speed
If your required profitable price is much higher than the market price, you may have a sourcing problem rather than a pricing problem.
Your options may include:
- Negotiate a lower supplier price
- Reduce packaging or logistics cost
- Choose a different supplier
- Create a higher-value bundle
- Find a different product
Warning:
Do not copy the lowest competitor price if that price would make your business unprofitable.
8. Test and Adjust the Price With Real Data
The first price you choose does not need to be permanent.
Monitor:
- Impressions
- Clicks
- Conversion rate
- Orders
- Ad spend
- Return rate
- Net profit
If the listing gets many views but few sales, price may be one possible problem.
If sales are strong but profit is too low, increasing the price may improve the business even if order volume falls slightly.
Price testing should focus on total profit, not only the number of units sold.
Recommended approach:
Use a pricing spreadsheet and update it whenever supplier costs, marketplace fees, shipping rates, advertising costs, or return rates change.
Simple Product Pricing Example
Imagine you sell a product for $40.
Your costs are:
- Product cost: $15
- Marketplace fee: $5
- Shipping and packaging: $6
- Advertising: $3
- Expected return cost: $1
Total cost:
$30
Net profit:
$40 − $30 = $10
Profit margin:
$10 ÷ $40 × 100 = 25%
That is much more useful than saying the product makes $25 because the supplier cost is only $15.
Profit Margin vs Markup
Markup compares profit with product cost.
Profit margin compares profit with selling price.
Example:
Cost: $50
Selling price: $100
Profit: $50
Markup:
100%
Profit margin:
50%
Mixing these two calculations can create serious pricing mistakes.
Common Product Pricing Mistakes
- Ignoring marketplace fees
- Forgetting shipping cost
- Ignoring advertising expenses
- Ignoring returns
- Confusing markup with margin
- Copying competitor prices blindly
- Pricing from revenue instead of net profit
- Failing to update prices when costs change
Frequently Asked Questions
What is the simplest formula for pricing a product?
Start with total cost per order, then add the amount of profit you need while accounting for percentage-based marketplace fees.
What is a good profit margin for ecommerce?
There is no universal margin. It depends on category, competition, advertising, returns, inventory turnover, and operating costs.
Should I match the cheapest competitor?
No. Match or beat competitor pricing only when the resulting price still meets your profitability target.
Should advertising be included in product pricing?
Yes, if paid advertising is a normal part of acquiring orders.
Why am I selling products but not making money?
Your selling price may not fully account for commissions, shipping, advertising, returns, packaging, or other costs.
