Profit after return costs

Profit lost

Use realistic estimates before buying. After an item sells, replace estimates with the real figures so you can see the true result.

How to use the answer

1 · Use real numbers

Start with evidence

Use what you paid and realistic selling figures rather than the best-case number.

2 · Keep a safety margin

Allow for surprises

Offers, refunds, extra postage and slow stock can change the final result.

3 · Record the real sale

Learn from what happened

The best calculator is useful only if you compare the estimate with the final sale.
