Hardware amortization
Spread acquisition cost over useful life. Cite A100 street price and useful life.
purchase $ ÷ compute-hours in useful life = $/compute-hour (hardware)Worked numbers
| input | value | cite |
|---|---|---|
| 2× A100 80GB | 2 × $12,500 = $25,000 | A100 street |
| Host + NIC | $4,000 | typical 1U dual-GPU host |
| Useful life | 36 months × 24 h = 26,280 h | Useful life |
Hardware floor if the box runs 24/7:
$29,000 ÷ 26,280 = $1.103 / compute-hour
If you only sell 5 hours/day (the capacity-listing window), life hours drop to 5/24 × 26,280 = 5,475 unless the remaining hours pay for the box elsewhere. Then:
$29,000 ÷ 5,475 = $5.297 / compute-hour
That is why spare-capacity sellers who already paid for the box on a daytime workload should not re-amortize the purchase on the night ask. Use spare capacity.
H100 check: 2 × $28,000 + $4,000 host = $60,000 ÷ 26,280 = $2.283 / compute-hour at 24/7 (H100 street).
Next: Spare capacity.
