Console Game Collection Value Calculator
Estimate the total resale/market value of your console game collection based on number of titles, average condition, rarity mix, and completeness (CIB vs loose).
...
Formula
Segment Values (before condition):
Loose Value = N × looseFrac × avgLoose
CIB Value = N × cibFrac × avgLoose × cibMultiplier
Rare Value = N × rareFrac × avgLoose × rareMultiplier
Graded Value = N × gradedFrac × avgLoose × rareMultiplier × gradedMultiplier
Condition Adjustment:
Adjusted Total = (Loose + CIB + Rare) × conditionFactor + Graded × (1 − (1 − conditionFactor) × 0.1)
Range: Low = Total × 0.80 | High = Total × 1.20
Assumptions & References
- Average loose value is user-supplied; check PriceCharting.com for current market prices.
- CIB (Complete In Box) games typically sell for 2–4× the loose price depending on console generation (NES/SNES higher, PS2/Xbox lower).
- Rare titles (e.g., Stadium Events, Panzer Dragoon Saga) can command 5–100× average values; the multiplier should reflect your specific titles.
- Professionally graded games (WATA, VGA) carry significant premiums, especially high-grade sealed copies; multipliers of 3–10× are common.
- Condition factors: Excellent = 1.0, Good = 0.85, Fair = 0.65, Poor = 0.40 — based on standard collectibles grading conventions.
- Graded games receive only a 10% weighting of the condition penalty since their grade is already locked in by the grading company.
- The ±20% range reflects typical market volatility and platform/regional demand differences.
- This calculator provides an estimate only; actual resale values depend on platform, title, region, and current market demand.
