How a score is built

The value score (0–100)

Each set is ranked against similar sets: the same theme and a similar size (under 200, 200–499, 500–999 or 1,000+ pieces). A size band with fewer than 8 sets is merged with its neighbor. On each factor below the set gets a percentile, and the score is their weighted average. 50 is typical for the group.

• Plastic per dollar: 35%
• Price per piece: 30%
• Minifigures per $100: 20%
• Builder rating: 15%

75+ is Great value, 60–74 Good value, 40–59 Average, 25–39 Below average and under 25 Poor value. If a factor is missing for a set, for example because it has fewer than 5 ratings, the other factors fill in its share.

Because sets are compared within their theme, a Star Wars set scoring 80 is great value for Star Wars. Licensed themes give less plastic per dollar, which the themes page shows.

Plastic per dollar

Price per piece is easy to game: a set full of tiny pieces looks cheap per piece. Plastic per dollar measures how much material you actually get. It's shown as an index: 100 is a typical set, 130 means about 30% more plastic for the money, and 80 means about 20% less.

The amount of plastic is worked out from each set's parts list: every part's weight times how many are in the set, minifigures included and spare parts left out. Packaging isn't counted, so a big box doesn't make a set look like better value. For 98% of sets the part weights are known; for the other 2% the amount is estimated from the kinds of parts in the set and marked "estimated". Weights themselves aren't published here, only the index.

The price check

Each set page also compares its MSRP with what a set with the same pieces, plastic and minifigures typically costs in its theme. That comes from a price model fitted on every rated set, which explains 95% of the differences in price. It's a separate method from the value score, and the two agree closely (rank correlation 0.85).

Prices

Prices are US MSRP. To compare sets from different years, they are adjusted for inflation to September 2026 dollars with the US consumer price index. When LEGO changed a set's price mid-life, the newer price may be used. Store discounts aren't counted yet.

What's included

4,604 sets from 37 themes released 2010–2027: Animal Crossing, Architecture, Bionicle, Botanicals, BrickHeadz, Castle, City, Creator 3-in-1, DC, Disney, Dreamzzz, Editions, Elves, Friends, Harry Potter, Hidden Side, Icons, Ideas, Juniors, Jurassic World, Legends of Chima, Marvel, Minecraft, Monkie Kid, Nexo Knights, Ninjago, Other LEGO themes, Other licensed, Pokémon, Sonic the Hedgehog, Space, Speed Champions, Star Wars, Super Mario, Technic, The LEGO Movie, Vidiyo. Left out: gear, books, magazine gifts, polybags, promotional items, sets without a US MSRP and sets under 25 pieces (2,548 in all). Sets with motors or hubs are scored but flagged: motors cost a lot and weigh little, so they look like poor value by these measures.
