Sellers Calculator

Running an online business or selling through platforms like Amazon, Etsy, or eBay? Knowing your true profit after all costs and fees is critical to growing and sustaining your business. That’s where our Seller Profit Calculator comes in.

This simple yet powerful tool helps you quickly determine your net profit, total costs, fees, and profit margin, all based on real inputs from your sales process. Whether you’re a seasoned online seller or just starting, this calculator makes it easy to know exactly how much you’re making — or losing — on each sale.


How to Use the Seller Profit Calculator (Step-by-Step)

Using the calculator is straightforward. Follow these steps to get accurate profit insights:

  1. Enter Product Cost ($):
    This is how much it costs you to produce or source one unit of your product.
  2. Enter Shipping Cost ($):
    Add the cost you pay to ship the item to the buyer (not what the buyer pays you).
  3. Enter Selling Price ($):
    Enter the final sale price you list or sell the product for.
  4. Enter Platform Fee (%):
    Many eCommerce platforms charge fees. This input is a percentage of your selling price, such as 10% for Etsy or eBay.
  5. Enter Other Fees ($):
    Include any fixed fees like payment processing, advertising, or packaging.
  6. Click “Calculate”:
    The calculator will instantly show you:
    • Total Cost
    • Platform Fees
    • Net Revenue
    • Profit
    • Profit Margin (%)
  7. Click “Reset” to start over with a new product or scenario.

Example: Calculating Profit for a Handmade Mug on Etsy

Let’s say you’re selling a handmade ceramic mug and want to check how profitable it is.

  • Product Cost: $5.00
  • Shipping Cost: $4.00
  • Selling Price: $25.00
  • Platform Fee: 10%
  • Other Fees: $1.50 (packaging, payment fees)

Click “Calculate”, and here’s what the calculator will display:

  • Total Cost: $10.50
  • Platform Fees: $2.50
  • Net Revenue: $22.50
  • Profit: $12.00
  • Profit Margin: 48%

This shows you’re making nearly a 50% margin, which is healthy for most online businesses.


Why This Tool Matters for Online Sellers

Selling online involves more than listing a price and waiting for sales. Platforms like Amazon, Etsy, Shopify, and eBay all take their cut — and those fees can sneakily eat into your profit.

Our calculator helps sellers:

  • Avoid underpricing by knowing the real cost of selling a product
  • Set competitive prices that leave room for actual earnings
  • Plan promotions and discounts while maintaining profitability
  • Compare multiple products or pricing strategies before launching

Whether you’re running a full-time eCommerce brand or selling as a side hustle, knowing your margins keeps your business healthy.


Bonus Tips for Maximizing Profit

  • Negotiate with suppliers: Lowering your product cost by even $0.50 can raise your margin significantly.
  • Use flat-rate shipping: Platforms like USPS or courier services offer discounted rates for volume shipping.
  • Batch packaging: Save on labor and materials by prepping orders in batches.
  • Track your averages: Use the calculator for every product to monitor which ones are performing best.
