5 Of The Top LEGO® Sets Under $20

Last updated October 26, 2026

Balling on a budget is the way to go. The best LEGO® sets under $20 prove you don’t need a flagship budget to have flagship fun. Whether you’re a seasoned LEGO® architect or a novice brimming with enthusiasm, affordability matters — and striking a balance between indulging your LEGO® passion and maintaining your budget can sometimes be challenging. Luckily, that’s where we come in. I’ve curated a list of five fantastic LEGO® sets under $20 — now updated for 2026 with current prices and retirement statuses, because a few of these picks have gotten interesting since I first wrote this.

The Importance of Affordable LEGO® Sets

With a plethora of designs, themes, and complexity levels, LEGO® provides a versatile platform that appeals to various ages and interests. But let’s be real – some of these sets can get quite pricey. Having affordable options within reach enables both casual builders and serious enthusiasts to enjoy the LEGO® experience without the financial stress.

Affordable LEGO® sets serve as an excellent introduction for beginners looking to start their building journey. They offer a taste of the creativity, problem-solving, and satisfaction that come with assembling a LEGO® set. Moreover, for the seasoned LEGO® builders, budget-friendly sets can complement existing collections, providing additional pieces and unique designs to inspire new creations. If $20 still feels steep, I’ve even rounded up LEGO® sets under $15 — yes, they exist.

Why LEGO® Sets Under $20 Are Secret Investment Vehicles

Here’s the lesson hiding in this list’s 2026 update: cheap LEGO® sets retire fast and without much fanfare. Nobody hoards a $19.99 slushy van — until it’s gone, and suddenly it’s a roughly $50 collectible as of October 2026. Four of my original five picks have retired since this post first went up (the fifth is retiring soon), and the Penguin Slushy Van alone has more than doubled. Budget sets fly under every investor’s radar, which is exactly why the ones with charm (penguin suits, exclusive minifigs) can outperform the big-ticket Icons sets on a percentage basis.

The takeaway: if a sub-$20 set makes you smile, buy it while it’s on shelves, and check the LEGO® sets retiring in 2027 list to see which ones are on the clock. Worst case, you’ve got a fun build. Best case, you’ve got a 2.5x. And if your budget stretches a little further, check out my picks for great LEGO® sets under $30.

LEGO® Sets Under $20 FAQ

What is the best LEGO® set under $20 in 2026?

The 501st Clone Troopers Battle Pack (75345) was the best army-building value in LEGO® Star Wars at $19.99, with four minifigures and a brick-built AV-7 anti-vehicle cannon. It retired in July 2026 and sells for roughly $20 sealed on BrickEconomy as of October 2026, so sealed copies are still going for about what they cost at retail. Of these picks, the one still on shelves is the LEGO® Creator 3-in-1 Exotic Parrot 31136 at $19.99. It is tagged retiring soon with an exit expected in December 2026, so grab it while supplies last!

Are LEGO® sets under $20 worth collecting?

Yes — budget sets retire quickly and with little notice, and charming ones can more than double after retirement. The Penguin Slushy Van went from $19.99 to roughly $50 sealed on BrickEconomy as of October 2026, within two years of retiring at the end of 2024.

Do cheap LEGO® sets have minifigures?

Plenty do. Battle packs are the gold standard — four figures for $20 — and most City and Harry Potter sets in this price band include two or three. Creator 3-in-1 animal sets typically skip minifigs in favor of more build pieces.

Finding reasonably priced LEGO® sets designed to captivate mature enthusiasts needn’t be an intimidating challenge. I’ve curated a collection of five standout sets, each costing less than $20 (at least when they were on shelves), that provide an array of immersive construction experiences and aesthetic display possibilities catering to diverse thematic preferences. So, whether it’s a self-indulgent treat or a thoughtful gift for another LEGO® aficionado, choose one of these cost-effective sets to kickstart an exciting building adventure.
