What Does Self-Hosting Cost?

Self-hosting has three ongoing costs: hardware (amortized), electricity, and internet. The upfront investment is real, but for most people, self-hosting pays for itself within 12–24 months by replacing cloud subscriptions. Here’s the actual math.

Prerequisites

Interest in self-hosting (Getting Started)
Basic understanding of what services you want to replace

The Cloud Subscription Bill

Most tech-comfortable households pay for some combination of these:

Service	Typical Monthly Cost
Google One (200 GB)	$3
iCloud+ (200 GB)	$3
Dropbox Plus (2 TB)	$12
1Password (Family)	$5
Netflix (Standard)	$15.50
Spotify (Family)	$17
NordVPN	$4
Google Workspace	$7
Notion (Plus)	$10
Adobe Creative Cloud (Photography)	$10
Backblaze (Computer Backup)	$9
UptimeRobot (Pro)	$7

Typical combined total: $50–150/month ($600–1,800/year)

Not all of these can be replaced by self-hosting (Netflix, Spotify require their content licenses), but storage, password management, VPN, notes, backups, and monitoring absolutely can.

Realistically replaceable: $40–80/month in cloud services.

Hardware Cost Tiers

Tier 1: Raspberry Pi ($50–120)

Component	Cost
Raspberry Pi 5 (8 GB)	$80
SD card (64 GB) or NVMe hat + SSD	$15–50
Power supply	$12
Case	$10
Total	$117–152

What you can run: Pi-hole, Vaultwarden, Home Assistant, Uptime Kuma, FreshRSS, small Nextcloud. ~5–10 lightweight services.

What you can’t: Jellyfin transcoding, large Nextcloud with many users, databases under heavy load. The Pi has 8 GB RAM and a quad-core ARM CPU — fine for lightweight services, insufficient for media-heavy workloads.

Electricity: ~5W idle, ~$5–7/year.

Tier 2: Mini PC ($150–350)

Component	Cost
Intel N100 mini PC (16 GB RAM, 500 GB SSD)	$150–200
External USB drive for backups (4 TB)	$80
Total	$230–280

Recommended models: Beelink S12 Pro, Trigkey G4, MinisForum UN100. All have Intel N100, 16 GB RAM, and 500 GB SSD.

What you can run: Everything a Pi can, plus Jellyfin (no transcoding), Nextcloud with 5–10 users, Immich for photo management, Gitea, monitoring stacks, 15–25 services simultaneously.

What you can’t: Heavy Plex transcoding for multiple streams, large AI workloads, very large databases.

Electricity: ~10–15W idle, ~$10–15/year.

This is the sweet spot for most self-hosters. Best performance per dollar.

Tier 3: Used Enterprise Mini PC ($100–250)

Component	Cost
Dell OptiPlex Micro or Lenovo ThinkCentre Tiny (used, i5 6th–8th gen, 16–32 GB RAM)	$80–180
SSD upgrade (if needed)	$30–50
External backup drive	$80
Total	$190–310

Advantage: More powerful CPUs than N100 for the same or less money. Supports hardware transcoding. 32 GB RAM options available cheaply.

Disadvantage: Higher power consumption (20–35W idle), older platform.

Tier 4: NAS ($300–800+)

Component	Cost
Synology DS224+ (2-bay)	$300
2× 4 TB HDD (Seagate IronWolf)	$200
RAM upgrade (optional)	$30
Total	$530

What you get: Dedicated storage appliance with Docker support, RAID protection, built-in backup tools, low power consumption.

Best for: Users who prioritize storage (photos, media, file sync) over compute-heavy workloads.

Electricity: ~15–25W, ~$15–25/year.

Tier 5: DIY Server ($500–1,500+)

Component	Cost
Case (Node 304 or rack mount)	$80–150
Motherboard + CPU (used Xeon or Ryzen)	$100–300
RAM (32–64 GB ECC)	$50–150
Boot SSD (500 GB)	$40
Storage drives (2–4× HDD)	$200–500
PSU	$50–80
Total	$520–1,180

For: Power users who need lots of storage, VMs, multiple concurrent streams, or want to learn server hardware.

Electricity: 50–100W idle, ~$50–100/year.

Electricity Costs

Electricity is the main ongoing cost. Calculate yours:

Annual cost = Watts × 24 hours × 365 days ÷ 1000 × $/kWh

US average electricity: $0.16/kWh (varies widely by state).

Hardware	Idle Watts	Annual Cost ($0.16/kWh)	Annual Cost ($0.30/kWh)
Raspberry Pi 5	5W	$7	$13
Intel N100 mini PC	12W	$17	$32
Used Dell OptiPlex	25W	$35	$66
Synology DS224+	20W	$28	$53
DIY server	70W	$98	$184

Measure don’t guess. A Kill-A-Watt meter ($20) shows actual power consumption. Idle power matters most — your server idles 95%+ of the time.

Internet Costs

You probably already pay for internet. Self-hosting doesn’t increase this cost unless:

You need a static IP (some ISPs charge $5–15/month extra)
You need higher upload speeds for remote access to large files
Your ISP blocks port 80/443 (use Cloudflare Tunnel or Tailscale to work around this — both free)

For most people: $0 additional internet cost.

Total Cost of Ownership

Example: Mini PC Setup (Most Common)

Year 1:

Item	Cost
Intel N100 mini PC	$175
4 TB external backup drive	$80
Domain name	$12
Electricity	$17
Total Year 1	$284

Year 2+:

Item	Cost
Electricity	$17
Domain renewal	$12
Total Year 2	$29

Comparison to Cloud Services

Assuming you replace $50/month in cloud subscriptions:

	Cloud	Self-Hosted
Year 1	$600	$284
Year 2	$1,200	$313
Year 3	$1,800	$342
Year 5	$3,000	$400

Break-even: ~7 months. After that, you’re saving $550+/year.

And you get:

Unlimited storage (add drives as needed)
No vendor lock-in
Full data ownership
No price increases from SaaS companies
Skills that transfer to professional IT

Hidden Costs to Consider

Time Investment

Self-hosting requires time:

Initial setup: 4–20 hours depending on complexity
Monthly maintenance: 1–4 hours (updates, monitoring, troubleshooting)
Learning curve: significant if you’re new to Linux and Docker

If your time is extremely valuable and you have zero interest in learning, self-hosting may not be worth it. For everyone else, the learning itself is valuable — and maintenance decreases dramatically after the first month.

Storage Growth

Photos and media grow over time. Budget for additional drives:

4 TB HDD: ~$80 (lasts most users 2–3 years)
8 TB HDD: ~$130

Hardware Replacement

Consumer hardware lasts 5–7+ years for server workloads. Budget ~$200 every 5 years for replacement.

Software Costs

Almost all self-hosted software is free and open source. Some optional paid tools:

Tailscale (free for personal use, up to 100 devices)
Plex Pass ($5/month or $120 lifetime — optional)
Custom domain ($10–15/year)

What You Can’t Self-Host (Economically)

Some services aren’t worth self-hosting:

Email: Deliverability is a nightmare. Use a paid provider ($3–5/month).
Content streaming (Netflix, Spotify, YouTube Premium): You’re paying for the content library, not the infrastructure.
Mobile app ecosystem (app store, phone OS): Can’t replace.
Massive-scale collaboration (Google Docs with 50 concurrent editors): Possible but not practical.

FAQ

Is self-hosting really cheaper than the cloud?

For most people replacing 3+ cloud services, yes. The math works in your favor by month 7–12. The more services you replace, the faster the payback.

What’s the cheapest way to start?

An Intel N100 mini PC (~$175) running Docker. It handles 15+ services, uses 12W of power, and runs silently. Start with Pi-hole, Vaultwarden, and Nextcloud — you’ll replace $15–20/month in subscriptions immediately.

Should I buy a Raspberry Pi or a mini PC?

Mini PC. For $50–75 more than a Pi 5 setup, you get significantly more RAM, an x86 CPU (better app compatibility), NVMe storage, and enough power for medium workloads. The Pi is great for single-purpose use (Pi-hole, Home Assistant) but limiting as a general server.

How much RAM do I need?

16 GB handles 15–20 typical services comfortably. 32 GB if you run databases, Nextcloud with many users, or memory-hungry apps like GitLab. 8 GB is tight — you’ll hit limits quickly.

Does self-hosting increase my electricity bill noticeably?

An N100 mini PC adds $1–3/month to your electricity bill. A DIY server adds $8–15/month. For most setups, electricity is a rounding error compared to cloud subscription savings.
