Selling on Amazon can be incredibly rewarding, but understanding how to calculate your profit is essential to building a sustainable business. Without a clear picture of your earnings, it’s impossible to scale effectively or make informed decisions. In this guide, we’ll break down how to calculate profit on Amazon sales, highlight key considerations, and offer tips to maximize your earnings.
Why Calculating Profit is Essential for Amazon Sellers
Profit isn’t just about revenue; it’s what remains after deducting all expenses, including fees, shipping, and product costs. Accurately calculating your profit helps you:
- Set Competitive Prices: Ensure you’re profitable while staying competitive.
- Identify Best-Selling Products: Focus on items that generate the most profit.
- Plan for Growth: Reinforce your cash flow and reinvest profits wisely.
Components of Amazon Profit Calculation
To calculate your profit, you need to consider several factors:

1. Selling Price
This is the price at which your product is sold to the customer. It is the starting point for any profit calculation.
2. Cost of Goods Sold (COGS)
COGS includes all costs associated with manufacturing, purchasing, or sourcing your products. This includes:
- Wholesale purchase price
- Shipping costs to your warehouse
- Import duties and taxes
Example: If you source a product for $10 and pay $2 in shipping, your total COGS is $12.
3. Amazon Fees
Amazon charges various fees depending on your selling plan and product category. Key fees include:
- Referral Fee: A percentage of the selling price (usually 8%-15%).
- FBA Fees: Costs associated with storage, packing, and shipping if you use Fulfilled by Amazon.
- Monthly Subscription Fee: $39.99/month for professional sellers.
Example: If you sell an item for $30 and the referral fee is 15%, Amazon takes $4.50 as a referral fee.
4. Shipping Costs to Customers
If you fulfill orders yourself, account for shipping expenses. For FBA sellers, these costs are included in the FBA fees.
5. Other Costs
Additional expenses may include:
- Advertising costs (Amazon PPC campaigns)
- Returns and refunds
- Storage fees for long-term inventory
Amazon Seller Profit Formula
Here’s a simple formula to calculate your profit:

Profit = Selling Price – (COGS + Amazon Fees + Shipping Costs + Advertising Costs)
Example Calculation
Let’s assume the following:
- Selling Price: $50
- COGS: $20
- Amazon Referral Fee: $7.50 (15% of $50)
- FBA Fee: $5
- Advertising Costs: $3
Profit = $50 – ($20 + $7.50 + $5 + $3) = $14.50
In this example, your profit per unit sold is $14.50.

Tools to Simplify Profit Calculations
Manually calculating profit for each product can be time-consuming. Fortunately, there are tools designed specifically for Amazon sellers:
1. Amazon Revenue Calculator
Amazon’s own calculator lets you input product details, selling price, and estimated costs to determine your profit margin.
2. FBA Profit Calculators
Third-party tools like Helium 10 and Jungle Scout offer profit calculation features, including advanced analytics.
3. Excel Sheets
Create a custom Excel sheet to track your product costs, fees, and profits. This allows you to customize calculations based on your business needs.
Tips to Maximize Amazon Profit
1. Reduce Product Costs
Negotiate with suppliers or purchase in bulk to lower your COGS.
2. Optimize Pricing
Use dynamic pricing tools to adjust prices based on demand and competition while maintaining profitability.
3. Lower Advertising Spend
Refine your Amazon PPC campaigns to focus on high-performing keywords and reduce wasted ad spend.
4. Minimize Storage Fees
Regularly review your inventory to avoid long-term storage fees. Consider using inventory management tools like RestockPro.
5. Bundle Products
Sell complementary items as bundles to increase the average order value.
Common Mistakes When Calculating Profit
1. Ignoring Hidden Fees
Amazon fees can vary depending on your product category, size, and weight. Ensure you account for all fees to avoid underestimating costs.
2. Overlooking Returns
Returns can significantly impact your profit margins. Factor in a realistic return rate for your products.
3. Miscalculating Shipping Costs
If you handle fulfillment yourself, always get accurate shipping quotes to include in your cost calculation.
