Brick Insights Sets Statistics FAQ

Not comparing apples to oranges anymore

Price Per Part

Can we really compare Price Per Part (PPP) between sets?

A couple of weeks ago I received this question by Jared Hinton:

"Just a quick question on the PPP data. Most years have a average PPP of 20c+ per part. This sounds very high, especially when most sets come way under that (which are then marked as good value). Do Duplo sets get included in the years average PPP figure? Because they tend to be alot higher than LEGO sets. This is the only thing I could think of why the year average is almost double what I'd expect it to be."

This is a very good observation, and something I hadn't really thought about. I built the PPP comparison when Brick Insights first launched in 2018, almost as an afterthought. I wanted to see if a set was worth buying from a MOCing point of view, and threw it in to help guide me. It was definitely time to take another look at those calculations.

All numbers in this article are adjusted according to inflation to make them comparable over the years. This isn't something we did before this investigation, so thank you for that too, Jared! Check the FAQ to learn the details about this. All categories referenced in this article are collected from Brickset, where we get most of our set data. That's also in the FAQ.

Average PPP for each category

If Jared's suspicion is correct we ought to see that some categories have a much higher PPP than others, which would skew the comparison.

Since we've got the PPP for each set, it's a simple matter to calculate the PPP for each category by averaging all individual values. If we display the average category PPP in a bar chart, we can quickly see if some categories differ a lot.

Finding comparable categories

Alright, Jared's suspicion is definitely correct - some categories sway the PPP comparison. The best way to solve this is by grouping the categories into comparable chunks. We want to ensure we compare apples to apples and oranges to oranges, so to speak. Here's the breakdown I came up with. It roughly groups categories together by part types.

Now, armed with this data, we can compare a set with other sets that are similar. You can see the grouping below, along with the average PPP of all times. But stick around - we can also see how prices have changed over the years!

And now, the ultimate question: what has happened to LEGO prices over the years?

With this grouping done we can do a quick calculation to figure out what the true Price Per Part has been over the years. Many people quote that a set should be priced at around $0.10 per part to be worthwhile. Is this the average?

Looking at the data, System and Technic sets have been pretty stable around $0.11 - $0.13 per part the last couple of years. Other categories are higher. We might need to revise that guideline a bit!

Play around with the chart below to have a closer look. You can toggle a category by clicking on it in the legend.

Fun stuff! How do I use it?

Whew, that was a rabbit hole, to say the least. With all of this done, the following things have now been improved on Brick Insights:

I have to say, doing this deep dive was super fascinating. I hope it'll prove useful to you. As always, let me know if you have any suggestions for improvements.

Hold on! I want to dig deeper into the data!

Happy to oblige - here's a bonus page with details. It contains charts displaying PPP and PPM for each category and comparable category over the years. Have fun!
