How the calculator works
This tool works out what you actually walk away with after selling a card, once all the costs that come out of the sale price are accounted for.
- Gross profit: Simply your sale price minus your purchase price — the headline number before any costs are deducted.
- Platform fee: The percentage a marketplace takes from your sale price. This varies by platform — selecting one from the dropdown fills in a typical rate, which you can adjust.
- Flat fee: A fixed per-order charge some platforms apply on top of their percentage fee.
- Shipping cost: What it costs you to send the card to the buyer.
- Grading cost (optional): If you had the card professionally graded before selling, include that cost here to see its true impact on your margin.
- Net profit: What’s actually left in your pocket — sale price, minus your purchase price, minus all fees, shipping, and grading costs.
- ROI: Net profit as a percentage of your total cost (purchase price + shipping + grading), showing how efficient the trade was relative to what you put in.
