☁️ Homelab vs Cloud — 5-Year TCO Comparison

See how your homelab stacks up against equivalent cloud instances over 5 years. Includes hardware depreciation, power costs, and cloud price increases.

Cloud Equivalent Monthly Yearly 5-Year Total Match?

Cloud prices based on on-demand US-East pricing (2026). Homelab 5-year cost = hardware (one-time) + power (yearly × 5). Cloud prices assume 20% annual increase for years 2-5. Egress and storage costs not included — cloud would be even more expensive.
