Some things to remember when attempting to flip sports cards for a profit and calculating costs and gains.

Your total cost isn’t just the amount you paid for a card—it’s the total amount you spent on a card. So, if you bought a card on COMC and had it shipped to you, your total cost of that card includes:

  • Amount paid for card
  • Supplies fee if you had it shipped in a toploader
  • Shipping and handling fee

Same thing if you bought a card on eBay. Yes, you might have bought the card itself for $100, but you also paid shipping, say $5 and then sales tax. When you sell the card and need to ship it, you’re paying for the label but also shipping supplies, etc.

All of this together represents your total investment in the card and should be considered when calculating profit.

This is why I’ve also included the cost to get a card graded in the calculator. This too is an amount you are putting into the card before you sell it, and needs to be factored in if you’re wanting to get a true estimate on how much you made selling a card you purchased.
