eBay Profit Calculator
Real eBay profit after fees.
Calculate eBay net profit after listing fees, final-value fees, payment processing, and shipping — the actual figure that lands in your account.
What this tool does
This calculator estimates your profit on a single eBay sale by working backward from the sale price through all applicable fees and costs. It takes your sale price, the item's actual cost to you, shipping charged to the buyer, your actual shipping expense, and the applicable final value and payment processing fee percentages, then subtracts these from your gross revenue to show bottom-line profit per transaction. The final value fee and payment processing costs have the greatest impact on your result, since they're calculated on your total revenue including shipping charged. This is useful for understanding how different pricing strategies—adjusting sale price or shipping charges—affect individual transaction outcomes. The calculator assumes standard fee structures and doesn't account for listing costs, returns, refunds, or platform-specific promotions that may apply to your account.

eBay fees bite hard. Final value fees 10-15% on most categories plus payment processing 2.9% + 0.30. This calculator shows true net profit after all fees.
50 sale with 30 cost and 8 shipping (5 actual) costs 9 in eBay fees after all charges. Net profit 15, margin 30%. Many sellers underprice because they don't account for fees properly.
Use before listing - reverse-calculate minimum price needed for target margin. Compare categories - final value fees vary (lower on some, higher on others).
A worked example
Try the defaults: sale price of 50, item cost of 30, shipping charged of 8, shipping actual cost of 5. The tool returns 13.48. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Sale Price, Item Cost, Shipping Charged, Shipping Actual Cost, and Final Value Fee %. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.
The formula behind this
Revenue = sale + shipping charged. Final value fee = revenue × %. Payment fee = revenue × 2.9% + 0.30. Profit = sale - cost - shipping loss - fees. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
What the score tells you
Headline financial numbers — income, savings, debt — each tell part of the story. This calculation stitches several together into a single read you can track over time. The value is in the direction, not the absolute number.
What this doesn't capture
The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.

Sources & Methodology
Methodology
The calculator computes net profit by subtracting all costs and fees from revenue. Revenue is defined as the sale price plus shipping charged to the buyer. Final value fees are applied as a percentage of this total revenue. Payment processing fees are calculated as a percentage of revenue plus a fixed amount per transaction. Profit is then computed by taking the sale price, subtracting the item cost, the difference between actual and charged shipping, and all applicable fees. The model assumes fees apply uniformly to all sales, treats shipping as a direct cost offset, and does not account for taxes, additional marketplace charges, inventory holding costs, or variable fee structures that may apply to different seller categories or sale volumes.
