BrickGains tells you what your LEGO sets are really worth and whether it's a good time to sell. It pulls real resale prices from the LEGO marketplace (BrickLink) and tracks your collection's value and ROI over time. It runs in your browser, nothing to install.
On the homepage, type a set number (for example 10276) or a set name, then press Check value. You'll see its real resale value (new and used), its retail price, its gain versus retail, and whether it's retired or still available.
No. Anyone can run 3 free value checks per day with no signup and no card. Create a free account to track sets, and upgrade for unlimited checks.

Add sets to your Watchlist and BrickGains flags whether the current market suggests it's a good moment to buy, hold or sell, based on price trends and retirement status.
Market Movers shows which sets are gaining or losing value the fastest right now, so you can spot opportunities and risks at a glance.

It estimates your real profit after fees when selling a set, so you know your true take-home before you list it.
Opt in from Account settings to get emailed when a watched set hits a price target, moves significantly, or is about to retire. You can turn them off anytime.
Prices are real recent data from the BrickLink marketplace, the reference for LEGO resale. New (sealed) and used prices are shown separately and update regularly.
They reflect real marketplace prices, but any actual sale depends on condition, completeness, region and timing. Treat the values as a strong, data-backed estimate rather than a guaranteed sale price.
A retired set is no longer produced by LEGO. Retired sets often rise in value because supply is fixed, which is why BrickGains tracks retirement status and dates.
