Used Hardware Value Calculator

Mining hardware loses value faster than almost any other computing equipment, driven by two forces at once: straightforward aging and the relentless efficiency gains of each new chip generation making yesterday's flagship comparatively wasteful. This calculator models aging first, with an exponential decay curve equivalent to 50% value loss per year (converted to a compounding monthly rate) applied to the original purchase price. That age-adjusted baseline is then multiplied by a technology ratio comparing your unit's efficiency in joules per terahash against a current best-in-class reference (21.5 J/TH, roughly a modern flagship ASIC) — a unit that's twice as power-hungry per hash as the current leader gets its value cut roughly in half by this factor alone, on top of age-based depreciation.

A market-condition multiplier then scales the whole estimate from 0.5× in a deep bear market up to 1.5× in a strong bull market, reflecting how used-hardware demand and pricing swing hard with coin prices and mining profitability sentiment. The final value is presented as a point estimate plus a ±20% low/high range, since actual resale prices vary by buyer, condition, and marketplace. A few figures are reported for context rather than feeding into the value itself — notably hashrate ratio (how your unit's raw hashrate compares to the current top model) — while remaining useful life assumes a flat 4-year (48-month) total economic lifespan regardless of how efficient or inefficient the unit already is, which is a simplification for older or newer hardware alike.
