Total Pieces

Minifigures

LEGO's API often returns 0 minifigs — manually count from the box or set page to factor into the score.

Piece Composition ▼

Auto-detected

Auto-detected breakdown based on set characteristics. Read-only — shown for transparency.

Print & Decoration ▼

0 printed / 0 stickers

Printed pieces add real cost (~$0.50/piece). Stickers cost almost nothing — and many collectors penalize them.

Printed Pieces

Pad-printed tiles, decorated minifig parts

Sticker Sheet Count

Number of stickers in the set's sticker sheet

Color Complexity ▼

Standard palette

Rare colors cost more to produce (small batch runs). Includes pearl, chrome, transparent-rare, lavender, medium azure, etc.

% Rare/Specialty Colors 5%

% Transparent / Translucent 3%

Production & Design ▼

Standard

Licensed IP

Star Wars, Marvel, Disney, Harry Potter — adds 10-15% royalty

Premium / Display Set

Icons, UCS, Architecture, 18+ adult sets command higher pricing

Functional Elements

Powered Up motors, lights, mechanical functions, Technic gearing

New Molds

Brand-new piece designs (~$50K+ tooling each)

Unique Part Types

Number of distinct piece molds in set

Build Time (min)

Estimated assembly time

Packaging & Materials ▼

Standard

Instruction Books

~$2 each in printing cost

Number of Bags

Total numbered bags in box

Premium Packaging

Magnetic close box, foam inserts, sleeve, collector packaging

Quality & Design ▼

Standard

Qualitative factors that swing real collector value up or down. Auto-detected where possible.

Collector Series

UCS, Icons, Modular Buildings, Architecture flagship — premium engineering built in

Model Completeness

Build Rigidity

Design Excellence

Build Engagement

Alternate Builds

1 for single, 3 for Creator 3-in-1

Engagement captures whether the build process itself is enjoyable or a slog of repetition

IP Demand Level

Years on Market

0 = new release, 5+ = proven classic

Avg Minifig Value ($)

Default $3.50; raise for exclusive/rare minifigs

Common ranges: generic $2-4, printed $4-8, exclusive/rare $10-30+

Redundancy & Filler ▼

0 pcs

Pieces that exist only because LEGO split one element into multiple smaller ones, padding the count without adding value.

Set Comparison

Calculate a set and add it here to compare

The Core Philosophy

Intrinsic Value = what you actually get (parts worth, minifig value, printed pieces, functional features, build experience). Brand Premium = what LEGO charges beyond that (tooling, license fees, distribution, profit).

Value Ratio = Intrinsic Value / Retail Price

Grading Scale

Grade	Ratio	Meaning
A+	≥ 0.85	Exceptional — rare true bargain
A	≥ 0.70	Excellent value
A-	≥ 0.58	Very good value
B+	≥ 0.48	Great value
B	≥ 0.40	Good value
B-	≥ 0.33	Decent — reasonable premium
C+	≥ 0.27	Fair — typical licensed set
C	≥ 0.22	Average — notable brand premium
C-	≥ 0.17	Below average value
D	≥ 0.13	Brand premium-heavy
D-	≥ 0.08	Heavily overpriced
F	< 0.08	Way overpriced

Piece Composition (8 Categories)

Category	~ Value/pc	Examples
Baseplates	$0.22	16x16+ baseplates, panels
Large Bricks	$0.07	4x4 to 8x8 bricks/plates
Standard	$0.03	1x2 to 2x4 bricks
Small Plates	$0.015	1x1 to 2x2 plates/tiles
Micro	$0.004	1x1 round, cheese slopes
Specialty	$0.06	Clips, hinges, plants
Technic	$0.042	Axles, gears, pins
Large Specialty	$0.11	Wheels, dishes, windscreens

Quality & Design Modifiers

Beyond raw parts value, these factors shape real collector value:

Collector Series (UCS, Icons, Modular, Architecture flagship) — +10% intrinsic, premium engineering
Model Completeness — a half Death Star is not a full Death Star. Partial/slice models get -20% to -40%
Build Rigidity — sturdy displays hold their own on a shelf (+10-15%); wobbly models lose value (-10%)
Design Complexity — masterpiece engineering (SNOT, illegal builds, novel techniques) adds 10-20%
Build Engagement — a tedious, repetitive assembly (World Map mosaic, Eiffel Tower lattice) knocks 12-25% off intrinsic value even if the result is impressive. Varied/multi-stage builds get a bump.
Alternate Builds — 3-in-1 Creator sets multiply piece utility
IP Demand — Star Wars/Marvel principal IPs have massive buyer willingness; niche IPs don't move the needle
Years on Market — longevity proves staying power; mature sets often worth a small bonus

Print & Decoration

Printed pieces add real value (no fading, premium feel, ~$0.30 each). Stickers are a quality cut — many collectors discount sets with lots of stickers.

Color Complexity

Rare and transparent colors cost more to produce in small batches. A set with many specialty colors (medium azure, lavender, chrome, trans-rare) has higher material value.

Minifigure Value

Default aftermarket value is ~$3.50/minifig. Exclusive or highly-printed minifigs (unique molds, rare variants) can command $10-30+ on the secondary market. Adjust the per-minifig value if the set has especially valuable characters.

Production Costs Shown for Transparency

Tooling/R&D, license royalties, and packaging are LEGO's costs — they explain why prices are what they are, but they don't add value to you as a buyer. The breakdown shows these so you can see where your money goes beyond the actual bricks.

Redundancy Penalty

When LEGO uses 2-3 small pieces where one existing piece would work, that padding inflates the count without adding build value. Estimate these and they'll be subtracted.
