Server Unit Economics Snapshot (Phase 0)¶
This note summarizes monthly unit economics for one server with 4 GPUs.
Assumptions¶
- Runtime basis: 730 hours per month
- Energy price: EUR 0.10/kWh (biogas partner site)
- Maintenance: EUR 600 per GPU per year
- Insurance: 3% per year of insured hardware value
- Site overhead (internet + location share): EUR 350 per month
- Home electricity sensitivity: EUR 0.35-0.37/kWh (private household)
- Marketplace host rates (after fees):
- A100 80GB: EUR 0.65 per GPU-hour
- A100 40GB: EUR 0.55 per GPU-hour
- Insured hardware value per server:
- 4x A100 80GB + server base: EUR 74,000
- 4x A100 40GB + server base: EUR 52,000
1) One server with 4x A100 80GB¶
| Utilization | Revenue (EUR/mo) | Energy (EUR/mo) | Maintenance (EUR/mo) | Insurance (EUR/mo) | Internet + Site (EUR/mo) | Total Costs (EUR/mo) | Net before financing (EUR/mo) |
|---|---|---|---|---|---|---|---|
| 70% | 1,328.60 | 81.67 | 200.00 | 185.00 | 350.00 | 816.67 | 511.93 |
| 80% | 1,518.40 | 81.67 | 200.00 | 185.00 | 350.00 | 816.67 | 701.73 |
Revenue formula (80GB): 0.65 * 4 * 730 * utilization.
2) One server with 4x A100 40GB¶
| Utilization | Revenue (EUR/mo) | Energy (EUR/mo) | Maintenance (EUR/mo) | Insurance (EUR/mo) | Internet + Site (EUR/mo) | Total Costs (EUR/mo) | Net before financing (EUR/mo) |
|---|---|---|---|---|---|---|---|
| 70% | 1,124.20 | 81.67 | 200.00 | 130.00 | 350.00 | 761.67 | 362.53 |
| 80% | 1,284.80 | 81.67 | 200.00 | 130.00 | 350.00 | 761.67 | 523.13 |
Revenue formula (40GB): 0.55 * 4 * 730 * utilization.
3) Home scenario: one server with 4x A100 40GB (private power)¶
Assumptions specific to this case: - Internet + site share set to EUR 0 (already covered privately) - Energy draw equivalent to the model basis: about 817 kWh/mo - Home energy range: - 817 * 0.35 = EUR 285.95/mo - 817 * 0.37 = EUR 302.29/mo
3A) Without separate hardware insurance¶
| Utilization | Revenue (EUR/mo) | Energy (EUR/mo, 0.35-0.37) | Maintenance (EUR/mo) | Insurance (EUR/mo) | Internet + Site (EUR/mo) | Total Costs (EUR/mo) | Net before financing (EUR/mo) |
|---|---|---|---|---|---|---|---|
| 70% | 1,124.20 | 285.95-302.29 | 200.00 | 0.00 | 0.00 | 485.95-502.29 | 638.25-621.91 |
| 80% | 1,284.80 | 285.95-302.29 | 200.00 | 0.00 | 0.00 | 485.95-502.29 | 798.85-782.51 |
3B) With separate hardware insurance (same 3% basis)¶
| Utilization | Revenue (EUR/mo) | Energy (EUR/mo, 0.35-0.37) | Maintenance (EUR/mo) | Insurance (EUR/mo) | Internet + Site (EUR/mo) | Total Costs (EUR/mo) | Net before financing (EUR/mo) |
|---|---|---|---|---|---|---|---|
| 70% | 1,124.20 | 285.95-302.29 | 200.00 | 130.00 | 0.00 | 615.95-632.29 | 508.25-491.91 |
| 80% | 1,284.80 | 285.95-302.29 | 200.00 | 130.00 | 0.00 | 615.95-632.29 | 668.85-652.51 |
Notes¶
- These are planning values, not final quote-backed values.
- VAT and depreciation are excluded from this operating view.
- If you use grid power instead of biogas, replace the energy column accordingly.
