GPU depreciation spreads an accelerator's purchase cost over its useful life, which drives the real cost of every GPU-hour.
One concept connected to AI compute market decisions.
A practical introduction designed to be completed in one sitting.
Useful for operators, analysts, investors, and procurement buyers.
Plain-English definition
Depreciation is how the cost of a GPU is spread over its useful life. Asking how fast an accelerator depreciates is asking how quickly an expensive chip loses economic value — through wear, newer generations, and falling rental rates — which sets how much of its purchase price must be recovered in each year it operates.
Why it matters
The assumed useful life of a GPU drives the cost of every GPU-hour an owner sells or uses. A longer assumed life spreads the purchase cost over more hours and lowers the hourly cost; a shorter life concentrates it. The AI-capex debate turns on whether operators are depreciating GPUs over too many years and understating the true cost of compute as newer chips arrive.
Simple example
Suppose an accelerator costs an illustrative $30,000. Spread straight-line over 3 years that is $10,000 a year; over 5 years, $6,000 a year. At an illustrative ~70% utilization (about 6,100 productive hours a year), the hardware-only cost is roughly $1.64 an hour at 3 years versus about $0.98 at 5 years — before power, networking, or facilities. The schedule alone moves the hourly cost by around 40%.
Example figures are illustrative calculations, not current quoted market prices.
Market signal
Disagreement over GPU useful life is a signal about the true cost of compute and about operator economics. If newer generations arrive faster or rental rates fall, effective useful life shortens and per-hour cost rises. Watch how operators state depreciation schedules and how quickly prior-generation rental rates decline.
Market read: the depreciation schedule is a hidden driver of compute cost and operator margin. Evidence discipline: state the purchase price, useful life, and utilization behind any per-hour cost, and treat schedules as assumptions, not facts.
Common mistake
Treating a GPU’s hourly cost as fixed. Most of it is recovered purchase cost spread over an assumed life and utilization — change either and the cost moves a lot. Assuming a long life also ignores that a newer chip can make an older one uncompetitive well before it physically wears out.
Practical takeaway
When you see a GPU-hour cost or an operator margin, ask what depreciation schedule and utilization it assumes, and test it against a shorter useful life.
Decision check: before trusting a low GPU-hour cost, check whether its assumed useful life survives the next generation of accelerators.
Helpful memory trick
A GPU usually goes obsolete before it wears out — economic life, not physical life, sets the clock.
