LEGO Set Value Formula:
| From: | To: |
The LEGO Set Value formula estimates the monetary value of a LEGO set based on the number of pieces, average price per piece, and a rarity factor. This calculation helps collectors and sellers determine fair market value for LEGO sets.
The calculator uses the LEGO Set Value formula:
Where:
Explanation: The equation calculates base value from piece count and price, then adds a premium for rare or hard-to-find sets.
Details: Accurate LEGO set valuation is crucial for collectors, investors, and sellers to determine fair market prices, insurance values, and investment potential.
Tips: Enter the total number of pieces in the set, the average price per piece in your currency, and a rarity factor between 0.00 and 1.00. All values must be valid (pieces > 0, price ≥ 0, rarity ≥ 0).
Q1: How accurate is this valuation method?
A: This provides a baseline estimate. Actual market value can vary based on set condition, completeness, box quality, and current market demand.
Q2: How do I determine the rarity factor?
A: Rarity factor is typically: 0.00-0.25 for common sets, 0.26-0.50 for uncommon, 0.51-0.75 for rare, and 0.76-1.00 for extremely rare/retired sets.
Q3: What's a typical price per piece?
A: Most LEGO sets range from $0.08 to $0.15 per piece, but licensed sets and complex builds can exceed $0.20 per piece.
Q4: Does this work for used LEGO sets?
A: For used sets, reduce the calculated value by 20-40% depending on condition, completeness, and presence of original packaging.
Q5: Are minifigures included in this calculation?
A: Rare minifigures can significantly increase value. Consider adding their separate market value to your final calculation.
