Unmetered vs unlimited bandwidth

Updated 2026-10-30

Unmetered bandwidth means the provider does not measure your monthly traffic for billing, so there is no per-GB or per-TB charge. "Unlimited bandwidth" is the phrase many people search for, and it usually means the same thing, but every connection still has a speed limit and a fair-use policy behind it.

The words are used loosely across the hosting industry. This guide separates them so you can read a plan sheet and know what you will pay.

Bandwidth and traffic are different things

Two quantities get mixed up all the time:

• Bandwidth is a rate: how much data can pass per second. It is measured in Mbit/s or Gbit/s and is set by the port your server is connected to.
• Traffic (or transfer) is a volume: how much data actually passed during a period. It is measured in GB or TB per month.

A road analogy works well. Bandwidth is the number of lanes. Traffic is how many cars drove on the road this month. A wide road can carry little traffic, and a narrow road can carry a lot if it is busy all day.

When a plan says "1 Gbit/s", it describes bandwidth. When it says "20 TB included", it describes traffic.

The three common models

1. Metered with an allowance

You get a monthly traffic allowance, for example a few TB. Beyond that, each extra GB or TB is billed. This is the most common model at large cloud providers.

• Good: predictable for low-traffic sites, often generous on paper.
• Watch out: a viral post, a backup sync or a misconfigured client can push you over and make the bill jump.

2. Metered with a hard cap

Once you use the allowance, the port is slowed down or blocked until the next month. You never pay more, but your service can degrade at the worst moment.

3. Unmetered

Traffic volume is not billed at all. You pay for the server, and the port speed is the practical limit. A fair-use policy protects other customers on the same network.

• Good: no surprise bills, simple budgeting, suits downloads, media, VPNs, backups and game servers.
• Watch out: read whether the port is shared or dedicated and what the fair-use policy says.

So what does "unlimited" mean?

Nothing physical is unlimited. A server port has a maximum speed, and the network behind it has finite capacity. When a provider says "unlimited bandwidth", it nearly always means one of these:

• traffic is not counted (unmetered), or
• a large allowance that most customers never reach, with fine print beyond it.

The honest version is "unmetered traffic with fair use". If a plan says unlimited, look for three facts: the port speed, whether that speed is shared, and what happens under heavy sustained use.

How to calculate what a port can carry

To turn bandwidth into a monthly volume, multiply the rate by the seconds in a month and divide by 8 to convert bits to bytes:

1 Gbit/s × 2,592,000 s (30 days) = 2,592,000 Gbit
2,592,000 Gbit ÷ 8 = 324,000 GB ≈ 324 TB per month

So a 1 Gbit/s port running flat out for a whole month moves about 324 TB. A 100 Mbit/s port moves about 32 TB. Real servers almost never run at full speed around the clock, so actual usage is a small fraction of that.

You can measure your own usage on Linux with vnstat:

sudo apt update && sudo apt install -y vnstat
sudo systemctl enable --now vnstat
# after some hours or days:
vnstat -m     # monthly totals
vnstat -l     # live rate

Shared vs dedicated ports

A shared port means the stated speed is the maximum your server can reach, and the capacity upstream is shared with other servers. Most of the time you get close to it; at busy times it may be lower. A dedicated or guaranteed port reserves the full rate for you, which is far more expensive.

For websites, APIs, VPNs and most self-hosted tools, shared ports are the normal and sensible choice. The bursts are short, and the speed is there when a page or download needs it.

What fair use really covers

A fair-use clause is not a hidden traffic limit. It lets the provider act when one server harms others: for example, sustained saturation that affects neighbours, or abuse such as attacks and spam. Typical actions are rate limiting or contacting you, not a surprise bill.

Before you buy, read the acceptable use policy and check:

• whether it names a number (if it does, that is an allowance in disguise);
• what the provider does first: warn, limit, or suspend;
• which uses are forbidden outright.

How Wolkra handles traffic

Every Wolkra cloud server includes unmetered traffic:

• no per-GB or per-TB fees and no traffic line on the invoice;
• ports up to 10 Gbit/s, shared;
• a fair-use policy in the acceptable use policy: we may limit resources that cause unusually heavy load for others.

That makes the monthly cost the plan price plus the extras you chose, nothing else. More details are on the network page and in unmetered bandwidth VPS.

When the model matters most

Traffic terms change the total cost most for:

• Downloads and media: file mirrors, podcasts, video, software updates.
• VPN servers: every byte your devices use passes through the server twice (in and out). See the WireGuard guide.
• Backups and sync: offsite copies of large data sets.
• Game servers and real-time apps: steady traffic all day.
• Scrapers, crawlers and CI runners that pull images and packages.

For a small blog, any model is fine. For these workloads, an unmetered plan removes the biggest variable on the bill.

Quick comparison

Summary

Bandwidth is speed, traffic is volume. "Unlimited" usually means unmetered, and unmetered means the volume is not billed, while port speed and fair use still apply. Compare plans on port speed, whether it is shared, overage price and the fair-use text, not on the word in the headline.
