What's the difference between margin and markup?

Margin is profit divided by selling price (e.g. $25 profit on $100 sale = 25% margin). Markup is profit divided by cost (e.g. $25 profit on $75 cost = 33% markup). A 25% margin equals a 33% markup. Margin is the finance-friendly metric; markup is the sales-friendly one.

How is break-even price calculated?

Break-even is the cost price — the minimum you'd need to charge to recover your direct costs without losing money. To include overhead, advertising, or transaction fees, add those amounts to the cost column.

Why is my blended margin different from the average of per-row margins?

Blended margin is total profit ÷ total revenue — it weights each product by its revenue. A high-margin product that sells little contributes less than a low-margin product that sells a lot. The simple average of margins treats every row equally regardless of revenue.

Can I add many products at once?

Yes. Click "Add product" as many times as you need. There's no enforced limit, but performance may degrade past a few hundred rows. The table is scrollable when it overflows.

How to use

1
Add products to the table
Start with the three sample rows or click "Add product" to add more. Each row tracks name, cost and selling price.
2
Type cost and price for each
Cost is what you pay per unit; price is what your customer pays. Profit, margin, markup and break-even update instantly as you type.
3
Read the per-row metrics
Profit shows in green (profit) or red (loss). Margin is profit ÷ price. Markup is profit ÷ cost. Break-even is the cost price — the floor below which you lose money.
4
Watch the blended totals
Top-of-screen stat cards show total revenue, total cost, total profit and the blended margin/markup across all products.

Common use cases

Audit a 10-product catalogue side-by-side to spot which SKUs drag the blended margin down.
Model new product launches by adding rows with proposed cost/price points.
Compare margin vs markup so sales and finance teams speak the same language.
Decide which products to discontinue — anything with a negative margin drags the total down.

Limitations

Marketplace and payment-processor fee schedules change frequently. The rates embedded in this calculator are illustrative and were last reviewed in early 2025 — always confirm the current fee schedule on the platform's seller documentation before pricing decisions.
This is gross margin — operating expenses, salaries, rent, payment-processing fees and shipping are excluded. A positive margin here does not guarantee overall business profitability.
Break-even is shown as the cost price. To include overheads, add a loaded cost (e.g. cost + $2 allocated overhead) in the cost column.
The blended margin divides total profit by total revenue across all rows. It does not weight by sales volume — use a weighted average if you sell very different quantities per SKU.
All amounts are displayed in your selected currency. Use the currency selector above the products table to change it — your choice is shared across every Dueneo money tool.
