Most LEGO calculators give you a number. We give you the math behind the number — and the context that tells you whether to trust it.
The fee math is real. eBay's final value fee is 13.25%. Payment processing adds 2.9% plus thirty cents. A typical UCS-sized set ships at $30–50 depending on zone. Calculators that quote "gross profit" and stop there overstate margins by 18–25% — a difference that regularly flips a real buy into a no-buy.
The comps are split. On any given set, sealed eBay comps and used eBay comps trade at wildly different prices — sometimes a 30%+ spread. Reading the wrong row is the most common, most expensive reseller mistake. Our calculators show both medians and force you to choose.
The part-out floor matters. Some sets sell sealed for years; others move faster broken into parts. The BrickLink part-out value isn't a hypothetical — it's the floor under your downside scenario. Knowing it before you buy turns a maybe-flip into a hold-with-confidence.
The retirement signal is the timing edge. UCS sets that retire often see meaningful price lift in the year after EOL. Knowing months early is the difference between paying retail and paying secondary.
Every tool here works on a single set, free, no signup. When you want this analysis on your full collection — saved, alerted on, and updated every morning — that's what BrickPicker Pro does.
Yes. Every tool here works without a signup, for any LEGO set we track. Saving calculations, getting alerts when target prices hit, and running calculations across your full collection live in the paid Brickfolio product.
Part-out totals are derived from current BrickLink price-guide data — the same source professional resellers use. We refresh on a 3-week cycle for the full tracked catalog and propagate sibling-color estimates so coverage is near-total. Methodology notes are on the part-out page.
By default the eBay final value fee (13.25%), payment processing (2.9% + $0.30), and an estimated shipping cost based on the set's box dimensions and a typical US destination zone. BrickLink, Mercari, and Amazon FBM are selectable alternates with their own fee tables.
Our retirement signal blends official LEGO end-of-life announcements (where available), Brickset retirement records, and a model trained on 15+ years of set lifecycles. The free tool exposes status and a window; the paid Predictions feature adds confidence intervals, portfolio-wide retirement risk, and alerts on new EOL announcements.
