💰 Instrument Value Calculator
Enter the purchase price, age, and condition of a brass instrument to get a rough current value — a quick reference for buying, selling, or insuring, not a formal appraisal.
💰 Estimate a Used Value
What is an Instrument Value Calculator?
It gives you a ballpark resale figure for a brass instrument. Starting from the price when new, it depreciates gradually with age, holds a sensible floor because quality horns keep a baseline value, and then adjusts for condition to land on a rough estimate.
Use it as a sanity check before you list an instrument, make an offer, or set an insurance value — then compare against recent sales of the same make and model, which move real prices far more than age alone.
❓ Frequently Asked Questions
How does the instrument value calculator work?
Enter what the instrument cost new, how old it is, and its condition on a 0-to-1 scale. It applies a straight-line depreciation of about 8% a year, never lets the value fall below 30% of the original price, then scales the result by condition to give a rough estimate.
Is this an appraisal?
No. It's a quick guide, not a valuation. Real prices depend heavily on brand, model, rarity, and current demand — a sought-after professional or vintage horn can hold or even gain value, while a generic student model depreciates faster. Always check recent sales of the same model.
Why is there a 30% floor?
Well-known brass instruments rarely become worthless. Even older, worn horns tend to retain some resale value because they can be overhauled and played for decades. The 30% floor reflects that a quality instrument keeps a baseline worth rather than depreciating to nothing.
How should I judge condition?
Consider lacquer or plating wear, dents, how freely the valves or slides move, and whether it plays in tune without leaks. Mint instruments sit near 1.0; heavily worn or needing-repair ones sit lower. Be honest — buyers will notice, and condition strongly affects price.
