You can manually adjust any field to test different scenarios. This is perfect for sports card investors, flippers, and sellers who want to maximize profits and avoid losses.


What Is ROI in Sports Card Investing?

ROI (Return on Investment) measures how much profit you make relative to your initial cost. In the world of sports card investing, ROI helps you evaluate whether grading, selling on certain platforms, or holding a card longer is worth it.

Formula:
ROI % = (Profit ÷ Purchase Price) × 100

Example:
If you buy a card for $100 and sell it for $200 after fees, your profit is $50.
Your ROI = (50 ÷ 100) × 100 = 50%

Tracking ROI helps you:

  • Compare raw vs graded card flips
  • Decide whether to sell now or hold
  • Evaluate which marketplaces give the best return
  • Avoid selling at a loss due to hidden fees

Use our calculator to make smarter decisions and grow your sports card portfolio with confidence.


Marketplace Fees Explained

Every selling platform takes a cut. Here’s how they impact your bottom line:

eBay

  • Typical seller fee: 13%
  • Additional ad/promoted listing fees may apply
  • Great for high-volume, lower-end cards

Goldin / PWCC

  • Consignment fee: 20% (average)
  • Ideal for high-end graded cards
  • Auction format may yield higher sale prices

Local / Facebook Marketplace

  • Fee: 0%
  • No shipping or platform fees
  • Best for quick flips and local meetups

Our calculator automatically adjusts for these fees, but you can override them manually. Understanding marketplace fees is critical for accurate ROI calculations and maximizing sports card profits.
