💰 Instrument Value Calculator
Enter the purchase price, age, and condition of a brass instrument to get a rough resale value — a quick reference for buying or selling, not a formal appraisal and not an insurance value.
💰 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 or make an offer, then compare against recent sales of the same make and model, which move real prices far more than age alone. Do not insure an instrument at this figure: a resale estimate is what a buyer might pay for yours, while replacing it after a loss costs what the same or an equivalent model sells for today.
❓ 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.
Can I use this figure to insure my instrument?
No. This is a resale estimate: what a buyer might pay for your instrument as it is. If it is lost, stolen or damaged beyond repair, you pay today's price for the same or an equivalent model, which is usually far more. Ask your insurer whether a policy pays replacement cost or a depreciated value, and for a valuable or vintage horn get a written appraisal.
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.
