Why break-even can exceed cost basis
A percentage selling fee is charged on the final transaction amount. The break-even formula solves backward through that fee instead of treating it as a fixed markup.

Find the minimum gross sale price needed to recover your card cost after percentage fees, fixed fees, grading, and shipping.
Quick answer
Break-even = (invested cost + fixed selling costs) ÷ (1 − percentage fee rate).
When the marketplace charges a percentage of the final sale price, simply adding that percentage to your cost understates the price you need. Break-even is the gross sale amount where net proceeds equal the complete invested cost.
