eBay Profit Calculator Formula
The core relationship between your selling price, costs, and profit is defined by the following equation, which can be rearranged to solve for any single missing variable.
Rearranged to solve for Sale Price (S):
S = (N + C + F) / (1 – R / 100)

Variables Explained
Understanding the inputs is key to accurate profit calculations:
- Final Sale Price (S): The total amount the buyer pays for the item, excluding any sales tax.
- Item Cost (C): Your total cost of goods sold (COGS), including the wholesale price, packaging, and inbound shipping.
- Net Profit Goal (N): The desired amount of money you want to keep after all costs and fees.
- eBay Final Value Fee Rate (R): The percentage eBay charges on the sale. This varies by category.
- Fixed Transaction Fee (F): The per-transaction fixed amount, typically around $0.30, charged by the payment processor.

What is the eBay Profit Calculator?
An eBay Profit Calculator is a vital tool for sellers to ensure profitability before listing an item. It automatically accounts for the complex, tiered final value fees (FVF) and fixed transaction costs that erode gross revenue.
Beyond simply calculating current profit, the advanced functionality allows sellers to perform reverse calculations. For instance, you can input your desired Net Profit Goal and the Item Cost to instantly determine the lowest possible Sale Price you must set to achieve that target, making it indispensable for competitive pricing.
How to Calculate eBay Profit (Example)
- Identify Inputs: You sell an item for $100.00 (S). Your Item Cost is $30.00 (C). The eBay Fee Rate is 13.25% (R), and the Fixed Fee is $0.30 (F).
- Calculate Percentage Fee: Convert the rate to a decimal and multiply by the Sale Price: $100.00 × (13.25 / 100) = $13.25.
- Calculate Total Fees: Add the percentage fee and the fixed fee: $13.25 + $0.30 = $13.55.
- Determine Net Profit: Subtract all costs and fees from the Sale Price: $100.00 – $30.00 – $13.55 = $56.45.
- The resulting Net Profit (N) is $56.45.
Frequently Asked Questions (FAQ)
The Final Value Fee is calculated based on the total amount of the sale, including the item price and any shipping charges (if applicable). It varies significantly depending on the product category.
Is the Fixed Transaction Fee constant?For most transactions, the Fixed Transaction Fee is a constant small charge, usually around $0.30 per order, regardless of the sale price. However, international sales might incur additional currency conversion fees.
Why do I need to solve for the Sale Price (S)?Solving for S is essential for reverse engineering your pricing. If you know what profit you need (N) and what the item costs you (C), the calculator determines the minimum listing price required to meet your profit objective.
What if I include shipping costs?For simplicity, this model focuses on S, C, N, and R. In reality, eBay’s FVF also applies to the shipping cost paid by the buyer. You should incorporate *all* costs (including seller-paid shipping) into the ‘Item Cost’ (C) for the most accurate ‘Net Profit’ (N) calculation.
