LEGO Price Per Piece Calculator
To get the price per piece, divide the set's price by its piece count: a $99.99 set with 1,254 pieces costs about 8 cents per piece. Enter your sets below to compare them, check a sale price, or see the price per gram.

How to calculate LEGO price per piece
Price per piece, often shortened to PPP, is the price of a set divided by the number of pieces in it. It is the quickest way to compare a $20 set with a $500 one, because it turns two very different boxes into the same kind of number.
Take the Medieval Castle (31120): $99.99 for 1,426 pieces. Divide 99.99 by 1,426 and you get 0.0701, so the castle costs about 7 cents per piece. Prices per piece are usually written with three decimals, like $0.070, because two decimals would round most sets to the same 10 or 11 cents.
Always use the price you will actually pay. A set that looks expensive at full price can be a good deal at 20% off, and the calculator's discount field handles that for you. The piece count is printed on the front of the box and listed on the LEGO website and on Brickset.
What is a good LEGO price per piece?
Fans have long used 10 cents per piece as the dividing line between a good deal and an expensive set. Prices have crept up over the years, and many recent sets now land between 10 and 13 cents. The tiers below are the ones this calculator uses. They are rules of thumb based on US dollar prices, not an official LEGO scale.
| Tier | Price per piece | What you usually find here |
|---|---|---|
| Great Large sets with lots of standard bricks, many Creator and Icons models, and good sales. | under $0.08 | Large sets with lots of standard bricks, many Creator and Icons models, and good sales. |
| Good Below the usual 10 cents. Plenty of unlicensed sets land here at full price. | $0.08 to $0.10 | Below the usual 10 cents. Plenty of unlicensed sets land here at full price. |
| Typical Where most current sets sit, including many big licensed and Technic models. | $0.10 to $0.13 | Where most current sets sit, including many big licensed and Technic models. |
| High Common for licensed themes, smaller sets and sets with large or special parts. | $0.13 to $0.16 | Common for licensed themes, smaller sets and sets with large or special parts. |
| Premium Small licensed sets, sets heavy on minifigures, and Duplo, where the pieces are big. | $0.16 and up | Small licensed sets, sets heavy on minifigures, and Duplo, where the pieces are big. |
Licensed themes cost more per piece because LEGO pays the owners of Star Wars, Marvel, Harry Potter and other brands for the right to use them. Sets packed with printed parts, new molds or minifigures also cost more to make. Duplo looks expensive on this scale because its bricks are much bigger, so a box holds far fewer of them.
Price per piece of popular sets
Here is how the math works out for a few well-known sets at their US list prices. Prices change, and some of these sets have retired, so treat the table as a worked example and enter today's price in the calculator.
| Set | Theme | Pieces | US price | Per piece |
|---|---|---|---|---|
| Eiffel Tower 10307 | Icons | 10,001 | $629.99 | $0.063 |
| Medieval Castle 31120 | Creator 3in1 | 1,426 | $99.99 | $0.070 |
| Galaxy Explorer 10497 | Icons | 1,254 | $99.99 | $0.080 |
| Avengers Tower 76269 | Marvel | 5,201 | $499.99 | $0.096 |
| Millennium Falcon 75192 | Star Wars | 7,541 | $849.99 | $0.113 |
| McLaren P1 42172 | Technic | 3,893 | $449.99 | $0.116 |
| Police Station 60316 | City | 668 | $99.99 | $0.150 |
The three $99.99 sets show why the number is useful. They cost the same, yet the Police Station works out to more than twice the price per piece of the Medieval Castle. The City set includes vehicles and several minifigures, while the castle is mostly regular bricks and plates.
Price per gram: when weight is the better measure
Price per piece has one well-known weakness. A 1x1 round plate and a large Technic panel each count as one piece, so a set full of tiny parts looks like great value even when it holds less plastic. Price per gram fixes that by dividing the price by the weight instead.
Neither number is right on its own. Price per piece suits most System sets, where parts are similar in size. Price per gram is fairer for Technic, Duplo and anything with big molded parts. When two sets rank differently on the two measures, the difference usually comes from part size, and you can decide which matters more for what you want to build.
That makes this tool a price per gram calculator as well: enter the weight in grams next to each set. Brickset lists weights for many sets. If you only have the shipping weight, remember that it includes the box and the instructions, so compare sets using the same kind of weight.
How to compare LEGO sets fairly
The comparison is most useful between similar sets. Two Star Wars ships, two Technic cars or two modular buildings make a fair match. Putting a licensed collector's model next to a City set mostly tells you that licenses cost money, which you already knew.
Sales change the picture more than anything else. Big retailers often take 20% or more off sets during holiday sales and clearance, which can move a set from the High tier to Good. Run the numbers at the sale price before you decide a set is overpriced.
Price per piece also ignores the things many builders care about most: minifigures, rare colors, the building experience and how the model looks on a shelf. Use it to spot real bargains and obvious overpricing, then let the set itself decide the rest.
Price per piece is not resale value
This calculator tells you what a set costs you per piece. It does not estimate what a set is worth on the secondhand market. For that, look up recent sales on sites such as BrickLink or BrickEconomy, which track retired sets and the value of their individual parts and minifigures.
Frequently Asked Questions
How do you calculate LEGO price per piece?
Divide the price of the set by its piece count. A $99.99 set with 1,254 pieces works out to $99.99 / 1,254 = $0.080 per piece, or 8 cents. If you bought it on sale, use the price you actually paid.
What is a good LEGO price per piece?
Anything under 10 cents per piece is generally seen as good value, and under 8 cents is very good. Between 10 and 13 cents is typical for current sets. Licensed themes such as Star Wars or Marvel often cost 13 cents or more per piece.
What is the average LEGO price per piece?
The figure most fans quote is about 10 cents per piece in US dollars, and many sets released in the last few years land between 10 and 13 cents. Small sets, licensed sets and Duplo usually cost more per piece than large unlicensed ones.
Is price per gram better than price per piece?
It answers a different question. Price per piece rewards sets full of tiny parts, while price per gram rewards sets with big, heavy parts. Looking at both gives a fairer picture, especially for Technic and Duplo. Use the weight of the set itself if you can find it, because box weight includes the cardboard and instructions.
Do minifigures count as pieces?
Yes. A minifigure is built from several parts, such as the legs, torso, head and hair or helmet, and those parts are included in the official piece count. A set with many minifigures therefore gets a few extra pieces from them, but each figure usually costs more to make than a basic brick.
Can I use euros, pounds or other currencies?
Yes. Pick your currency and the calculator shows every result in it. Exchange rates are not applied, so enter local prices. The value tiers are based on US dollar prices, so the scale is shown for dollars and euros only.
