LEGO Collection Value Calculator — How Much Is Your LEGO Worth?

Add your LEGO set numbers below and we'll calculate your collection's total market value using live eBay pricing data.

How the LEGO Collection Value Calculator Works

Enter your LEGO set numbers (found on the box or instructions) and our calculator fetches real-time market data from eBay to determine what each set is currently selling for.

We show both new sealed and used complete prices when available, giving you an accurate picture of your collection's total market value.

Where to Find Your Set Number

  • On the front of the box (usually top-right corner)
  • On the first page of the instruction booklet
  • On the side of the box near the barcode
  • Use our AI scanner to identify sets from photos
