Self-Hosted Cloud Storage in 2026: The Real Cost Calculator

Dropbox Plus is $120/year for 2 TB. Google One is $100/year for the same. But what if you self-host? Let me show you the real 5-year cost of running your own Nextcloud box, and when the math works out.

The Hardware

You need a small always-on PC, a couple of drives, and a domain name. A reasonable 2026 setup:

• Beelink N100 mini PC: $160
• 2 x 8 TB IronWolf NAS drives: $300 total
• UPS (APC BE600M1): $65
• Domain name (5 years): $60 total

Total upfront: $585

The Electricity

A Beelink N100 idles around 6W and pulls 15W under load with two drives. Average maybe 12W. At 12W 24/7 over a year:

12W * 24h * 365 = 105 kWh per year

At a US average of $0.16/kWh: $16.80/year for electricity. Plus drive replacement every 5 years ($300 amortized = $60/year).

Annual operating cost: ~$77/year (mostly the drives).

The Software

• Nextcloud: free, open source
• OS (Ubuntu Server LTS): free
• ScsDriver to mount the WebDAV share on Windows: $5.5 lifetime
• Tailscale for remote access: free for personal use

Total software: $5.5 one-time

5-Year Total Cost

Item	5-year cost
Hardware upfront	$585
Electricity	$84
Drive replacement	$300
Domain (5y)	$60
ScsDriver (lifetime)	$5.5
Total	$1034.5

5-Year Cost of Dropbox Plus (2 TB)

$120/year * 5 = $600

Wait, Dropbox is Cheaper?

On paper, yes. But consider:

• 2 TB cap: you outgrow it as your library grows
• Privacy: your files live on Dropbox servers
• Speed: depends on Dropbox servers, not your home connection
• Vendor lock-in: if Dropbox raises prices, you pay or leave

With self-hosting:

• Capacity scales by adding drives (~$150 per 8 TB)
• Privacy: files stay on your hardware
• Speed: 1 Gbps home LAN = 100+ MB/s to every PC
• No vendor: the box runs as long as the electricity does

When Self-Hosting Wins

• You have more than 1 TB and are growing
• You care about privacy (medical, financial, creative work)
• You have upload-heavy workflows (video, photo backup)
• You already have a home server or NAS

When Dropbox Wins

• You need less than 1 TB
• You want zero maintenance
• You travel a lot and want seamless sync to mobile
• You don't want to learn Linux

The Mount Story

Once your Nextcloud is up, the next decision is how to access files on Windows. The browser interface is fine for occasional use, but if you edit documents, photos, or videos directly, you want a mounted drive.

ScsDriver at $5.5 lifetime does this for Windows: it mounts your Nextcloud as drive N: and any program can read/write files directly. No two-way sync, no conflicts, just a drive letter.

For $5.5 one-time, the WebDAV mount is a small add-on that makes the whole self-hosting setup feel native on Windows.

Verdict

If you have a home with reliable power and a 1 Gbps LAN, self-hosted Nextcloud is the cheaper option in 5-year terms only if you need more than 1 TB. If you need only 500 GB and travel often, Dropbox Plus is more pragmatic.

For most home-lab enthusiasts with growing libraries, the self-hosted path at $1034 over 5 years is competitive with Dropbox once you factor in capacity scaling and privacy. And once the box is set up, the marginal cost of the next 8 TB is just the drive.
