Self-hosting break-even: $23/month of SaaS, a $170 mini PC, about 9 months

Description and use

A $170 mini PC with 15 W idle draw cuts monthly SaaS costs from $22.97 to $7.30, saving $15.67 per month and breaking even in 9 months.

Problem

Deciding whether self-hosting services can offset SaaS subscription costs and when it pays off.

Outcome

A $170 mini PC with 15W idle draw and modest backup/maintenance costs reduces monthly SaaS spend from $22.97 to $7.30, yielding a $15.67 monthly saving and a 9‑month break‑even. Higher‑cost hardware (e.g., $800 server for $10/month storage) never pays back within the chosen 5‑year lifetime.

Workflow

• 1. Identify SaaS services and monthly costs.
• 2. Choose self-hosting hardware and estimate power draw.
• 3. Input electricity rate, maintenance, backup costs into calculator.
• 4. Run calculator to get monthly savings and break-even period.
• 5. Review ongoing monthly costs and compare to SaaS savings.
• 6. Decide whether to purchase hardware based on break-even and lifetime.
• 7. If proceeding, set up chosen self-hosted services (e.g., Vaultwarden, Jellyfin, Uptime Kuma, Immich).

Evidence

Replacing $23/month in SaaS subscriptions (Google One 2TB + 1Password + Plex Pass) with a $170 mini PC drawing 15W idle breaks even in about 9 months.
