Pricing a used board game for a trade or auction is guesswork without a consistent method. This calculator turns MSRP, condition, completeness, age, and demand into a transparent fair-value range, so you can trade and bid with confidence instead of gut feel.
How it works
The estimate is MSRP scaled by a chain of multipliers:
value = MSRP × condition_factor × completeness_factor × demand_factor × age_factor
Condition runs from Mint (near full value) down to Fair (about a third). The completeness factor penalises missing components more steeply than a worn box, because a missing component breaks playability. Demand bumps sought-after out-of-print titles up and discounts readily available in-print games. A mild age factor reflects gradual wear and edition obsolescence. The tool then shows a low-to- high range around the central figure.
Tips and notes
Use the low end as a quick trade-in figure and the high end as a patient private- sale or auction target. Condition and completeness dominate the result, so be honest: sleeved cards, an organiser insert, punched-but-bagged tokens, and original shrink justify the top of the range, while water damage, missing rulebooks, or a crushed box pull it down. For genuinely valuable out-of-print titles, always cross- check the estimate against recent completed marketplace sales before agreeing a price.
