Amazon Seller Income Calculator

How to Use the Calculator: Units, Price, Profit per Unit

The calculator turns three numbers into three concrete results: monthly revenue, monthly profit, and annual profit. Using it comes down to filling in three fields and reading the answers.

• Units / month — how many units of the product you sell in a typical month. The default is 500.
• Price — the selling price of one unit. The default is 24.99.
• Profit / unit — the amount left from each unit sold after subtracting the costs you want to include. The default is 6.

It is best to start with your own real numbers. The unit count should match what you actually sell in a month, not what you only plan to sell. Price is the amount a customer pays for one unit. The third field is the most important because both profit results depend on it — the more accurately you set it, the more useful the final numbers will be.

The tool displays amounts in dollars. If you sell in another currency, enter your figures in that currency and keep the same currency in both fields — the math will work in that currency.

How to Calculate Monthly and Annual Revenue

The whole logic is based on multiplication. The three relationships look like this:

• monthly revenue = units × price,
• monthly profit = units × profit per unit,
• annual profit = monthly profit × 12.

You can calculate annual revenue by multiplying monthly revenue by 12. This comparison is useful when planning a budget, supplier orders, or a conversation with an accountant.

Here is how it looks with the default values:

Where do these numbers come from? 500 units × 24.99 = 12,495, or $12,495.00 in monthly revenue. 500 units × 6 = $3,000.00 in monthly profit, and 3,000 × 12 = $36,000.00 per year. Note that revenue here is more than four times profit — that is the difference between sales and what remains after costs.

How Revenue Differs from Net Profit on Amazon

Revenue is the money customers paid for your products. In this tool, it is calculated as units × price, meaning gross sales. It is not the amount Amazon will transfer to your account — commissions, logistics fees, and other charges sit between sales and payout.

Net profit is what remains after subtracting all costs from revenue: product sourcing, platform commissions, logistics and storage fees, advertising, packaging, returns, and taxes. The tool does not guess these costs — it takes profit per unit exactly as you enter it and multiplies it by units.

This leads to two ways to use the calculator:

• If you enter profit after subtracting all costs, the monthly and annual profit results will be close to your net profit.
• If you enter only the difference between price and product cost, the result will show profit before platform fees.

Stick to one definition each time you calculate. Then you are comparing scenarios that are truly comparable.

How to Include Amazon Fees and Costs in the Calculation

The tool does not include any platform rates or storage, advertising, or tax costs. This is intentional: fees depend on product category, size, weight, sales country, and change over time. Instead of guessing current rates, calculate profit per unit yourself and enter the finished amount.

Step by step:

1. Start with the selling price of one unit.
2. Subtract the cost to buy or make the product.
3. Subtract the commission charged by the platform for the sale.
4. Subtract logistics, storage, and packaging fees.
5. Subtract advertising and marketing costs per unit.
6. Subtract returns, damage, and other losses.
7. Subtract taxes and charges you want to include.

Enter what remains as profit per unit. Profit per unit = selling price − total costs per unit.

Check the current fee schedule in your seller dashboard, because rates change with category and platform policy. When you want to see how fees affect the result, calculate everything twice: once with profit before fees, and again after subtracting them, and compare both sets of results. The difference shows how much costs really take.

Limitations and What the Tool Does Not Calculate

The calculator calculates exactly what you enter and nothing more. Treat the results as a starting point for further analysis, not as a finished profit and loss statement.

• It does not include platform fees. It has no sales commissions, logistics fees, or storage fees.
• It does not account for taxes. It does not add VAT, income tax, or customs duties — you account for their impact yourself in the profit per unit field.
• It does not know your costs. Product sourcing, packaging, advertising, returns, or shipping depend on your situation.
• It does not track changes over time. The numbers you enter describe one scenario; seasonality, promotions, and demand fluctuations are not considered.
• It does not convert currencies. Amounts are shown in dollars, and by entering your own figures you can calculate in any currency.
• It does not tell you what the platform payout will be. Revenue is gross sales, not the transfer amount.

The result is approximate whenever your real costs differ from the profit per unit you entered. It is most valuable when the profit field contains a number calculated from invoices and current rates — then the monthly and annual amounts become a realistic plan. Also remember that revenue alone does not tell you whether the business is profitable: sales can grow while profit stays low if costs are high.
