What is a good price for a LEGO set? Work it out per piece
One division shows whether a set is expensive or cheap, and when that rule of thumb works less well.

How to calculate the price per piece
Divide the price of the set by the number of pieces. A set of 1000 pieces for 100 euros costs 10 cents per piece. The same set at 80 euros comes to 8 cents per piece. The number of pieces is on the box and in the product details of every shop.
A rule of thumb to compare with
Among LEGO fans, about 10 cents per piece counts as a good price. The site Brickset calls sets below that line a bargain. For licensed sets such as Star Wars, the price was often between 12 and 20 cents. Those figures are in US dollars, so use them as a rough guide for Belgium.
When the rule of thumb works less well
- Large sets often come out below 10 cents per piece. Small sets often sit above it, because packaging and design weigh more heavily.
- Licensed sets, such as a film or a sports star, often cost more per piece. Unlicensed ranges such as Technic, Creator, Ninjago and Friends often score better according to Brickset.
- Pieces differ in size. A set with large moulded parts counts differently from a set with many small pieces.
- Minifigures and special parts are a reason to buy for many people, even when the price per piece is high.
Use it to judge discounts
The price per piece helps you see whether a discount is really worth it. A crossed-out price does not always tell you how the set was priced before, so work out for yourself what you pay per piece.
