Can a VPN Affect Internet Speed?
What changes, why it happens and what our real VPN speed tests show
Yes, a VPN can affect internet speed. A VPN adds encryption and sends your traffic through a VPN server before it reaches the website, app or streaming service you are using. That extra step can reduce download speed, change upload speed and increase ping.
The important part is how much it changes. On a nearby, well-run server, the difference can be so small that you barely notice it. On a distant server, or one that is busy, the drop can be obvious — especially for gaming, video calls and large downloads. If your results are worse than expected, the fix is usually to test first, then change one setting at a time.
In our own speed testing, a 536.70 Mbps baseline connection still averaged 517.17 Mbps through a local UK NordVPN server. That is a real drop, but not one most people would feel in normal browsing or streaming. Distance made a bigger difference: New York averaged 458.28 Mbps from the UK, while Melbourne averaged 311.75 Mbps.
Usually affected first
Download speed can fall because of encryption overhead, server load and the route your traffic takes. Good VPNs keep this loss small on local servers.
Distance matters most
Ping normally rises when you connect through a VPN, especially if the server is in another country or continent.
Not all VPNs are equal
A fast protocol and high-capacity servers can make the speed impact surprisingly small. A weak provider can turn the same line into a bottleneck.
What Our VPN Speed Tests Showed
The cleanest way to answer whether a VPN affects internet speed is to compare the same connection with and without the VPN. In our testing, the direct Virgin Media line averaged 536.70 Mbps download, 50.93 Mbps upload and 11.67 ms ping. That became our 100% reference point.
We then tested NordVPN across local, transatlantic and long-distance servers. These figures are used here as real-world examples of how speed changes as distance and routing change. You can see the full raw results on our NordVPN speed test results page.
| Connection | Average download | Download retained | Average upload | Average ping | What it tells us |
|---|---|---|---|---|---|
| No VPN baseline | 536.70 Mbps | 100% | 50.93 Mbps | 11.67 ms | The raw line was performing above its advertised 500 Mbps tier, so later drops are more likely to come from VPN overhead, routing or server distance. |
| UK Manchester | 517.17 Mbps | 96.36% | 43.76 Mbps | 25.00 ms | Local VPN use caused only a small download loss. For ordinary browsing, streaming and downloads, this kind of drop would usually feel invisible. |
| USA New York | 458.28 Mbps | 85.39% | 48.01 Mbps | 90.67 ms | Longer distance increased latency, but download speed stayed strong enough for heavy streaming and large file downloads. |
| Australia Melbourne | 311.75 Mbps | 58.09% | 35.79 Mbps | 305.33 ms | The distance penalty was obvious, especially in ping, but throughput was still unusually high for a UK-to-Australia VPN route. |
What the numbers mean in plain English
The local UK result shows the best-case version of VPN speed loss. Encryption and tunnelling still added overhead, but download speed stayed above 96% of the no-VPN connection. That suggests the VPN was not acting as a meaningful bottleneck nearby.
The New York result is more interesting. The connection crossed the Atlantic and ping climbed to about 91 ms, yet download speed still averaged over 458 Mbps. That is the kind of result that shows why distance affects latency before it necessarily destroys throughput.
Australia shows the trade-off clearly. The connection was still fast enough for demanding use, but the 305 ms ping would not be ideal for reaction-based gaming or real-time work. For streaming or downloading, it could still be perfectly usable.
Why Does a VPN Slow Internet Speed?
A VPN does not slow your internet by magic. It changes the route and processing your traffic goes through. Sometimes that change is tiny. Sometimes it is the difference between a smooth connection and a frustrating one.
Encryption overhead
Your device has to encrypt outgoing traffic and decrypt incoming traffic. Modern protocols are much faster than older options, but this still takes processing time.
Server distance
A nearby VPN server usually gives better speed and lower ping. A server on another continent forces traffic to travel further, which mainly hurts latency. After switching location, it is worth using an IP checker to check your visible IP address and confirm the VPN exit location changed as expected.
VPN server load
If too many users are sharing the same server, speed can dip. This is why the same VPN can feel fast at one time of day and slower at another.
Protocol choice
WireGuard-based protocols are usually faster than older OpenVPN setups. Some apps choose automatically, but manual switching can help when speeds look wrong. After changing server or protocol, you can also check whether your VPN is working before judging the speed result.
Your device and router
Older phones, laptops and routers can struggle with VPN encryption at high speeds. This matters more on fast fibre and gigabit connections.
Routing and peering
Sometimes the route through a VPN is simply less direct than your normal ISP route. In rare cases, the opposite happens and the VPN route performs better.
How a VPN Affects Download Speed, Upload Speed and Ping
Speed-test results can be misleading if you only look at the download number. A VPN can affect each part of the connection differently.
Download speed
This is the number most people notice first. It affects web pages, app downloads, large files and video quality. In our local UK example, download speed dropped from 536.70 Mbps to 517.17 Mbps, which is a small loss for a VPN connection.
Upload speed
Upload speed matters for video calls, sending files, livestreaming and cloud backups. It can be less predictable than download speed because upload capacity is often lower to begin with.
Ping
Ping is the delay before data starts moving. It matters more for gaming and calls than for watching video. The UK server averaged 25 ms, New York averaged 90.67 ms and Melbourne averaged 305.33 ms, which shows how quickly distance changes the feel of a connection.
Stability
A stable 150 Mbps connection can feel better than an unstable 500 Mbps one. If a VPN server keeps spiking, dropping packets or switching routes, you may see buffering even when the headline speed looks fine.
Will a VPN Affect Streaming, Gaming or Video Calls?
It depends on what you are doing. Streaming and downloading mostly care about bandwidth. Gaming and live calls care much more about ping, jitter and packet loss.
| Activity | What matters most | How a VPN can affect it | Best approach |
|---|---|---|---|
| Browsing | Latency and stability | Nearby servers usually feel normal. Far-away servers may make pages start loading more slowly. | Use the nearest reliable server. |
| Streaming | Download speed and consistency | A fast VPN can stream smoothly. A crowded or distant server can cause buffering or lower quality. | Choose a server in the country you need, then test a few locations. |
| Gaming | Ping, jitter and packet loss | Even if download speed is high, a distant VPN server can make games feel delayed. | Use a local server, or do not route the game through the VPN unless needed. |
| Video calls | Upload, ping and stability | Calls may freeze if upload speed dips or the server becomes unstable. | Use a nearby server and avoid overloaded Wi-Fi. |
| Torrents and large downloads | Sustained download and upload | A good VPN can stay quick, but weak servers may throttle long sessions. | Use a provider that allows the traffic type and has strong nearby capacity. |
Can a VPN Ever Improve Internet Speed?
Sometimes, but it is not the normal expectation. A VPN can occasionally improve speed if your ISP has a poor route to a service, if a particular path is congested or if traffic shaping is affecting a type of connection. By sending traffic through another route, the VPN may avoid the problem.
That does not mean a VPN is a speed booster. Most of the time, the extra encryption and routing add at least a little overhead. If a provider advertises a VPN as making every connection faster, treat that as marketing rather than a guarantee.
How to Stop a VPN Slowing Your Internet Down
If your VPN speed drops more than expected, do not assume the service is broken straight away. Work through the simple fixes first. For a deeper step-by-step guide, see how to speed up your VPN connection.
Start with the server
- Pick a server in your own country for normal browsing.
- Try a different city if one location feels overloaded.
- Avoid far-away servers unless you need that country.
Check the protocol
- Use WireGuard or a WireGuard-based protocol where available.
- Switch away from OpenVPN if speed is the priority.
- Let the app auto-select if you are not sure.
Rule out your own network
- Test without the VPN first, then test with the VPN on.
- Try wired Ethernet if Wi-Fi results jump around.
- Restart the router and VPN app if results suddenly collapse.
- Use our guide to fix a slow VPN connection if the drop happens across several servers.
Use split tunnelling
- Keep sensitive apps inside the VPN.
- Let low-risk, speed-sensitive apps use the normal connection.
- Use this carefully on shared or public networks.
How to Test Whether Your VPN Is Affecting Your Speed
One speed test is not enough. Wi-Fi, server load and local congestion can all create misleading results, so it is better to test in a simple pattern. You can use our tool to test your internet speed before and after connecting to the VPN.
- Turn the VPN off and run three speed tests to the same nearby test server.
- Average the download, upload and ping results. This is your baseline.
- Turn the VPN on and connect to a nearby VPN server.
- Run three more tests, preferably to a nearby test server again.
- Repeat with a distant VPN server if you use one for streaming or travel.
- Compare percentages, not just raw Mbps. A 50 Mbps drop sounds big on a 100 Mbps line, but small on a 900 Mbps line.
This is the same basic idea behind our NordVPN testing: establish the no-VPN capability first, then compare each VPN location against that baseline.
So, Can a VPN Affect Internet Speed?
Yes. A VPN can affect internet speed because it encrypts your traffic and routes it through another server. That can reduce download speed, change upload performance and increase ping.
But the size of the effect depends heavily on the VPN. In our real-world tests, a local NordVPN server retained more than 96% of our baseline download speed, while a New York server retained more than 85%. The big difference came with Australia, where the long distance pushed ping above 300 ms and download retention fell to about 58%.
For normal privacy, public Wi-Fi and day-to-day browsing, a good nearby VPN server should not feel slow. For gaming, video calls or remote streaming, server choice matters a lot more. Pick the closest server that does the job, use a modern protocol and test before blaming the VPN alone.
Can a VPN Affect Internet Speed? FAQs
Can a VPN affect internet speed?
Yes. A VPN can affect internet speed because your traffic is encrypted and routed through a VPN server before reaching the wider internet. The impact can be small on a nearby, fast server, but it can become more noticeable when the server is far away, overloaded or using a slower protocol.
Does a VPN always slow down internet speed?
A VPN usually adds some overhead, so a small speed drop is normal. However, the difference may be hard to notice if you use a nearby server, a modern protocol and a provider with enough capacity. In some cases a VPN can also improve a poor route or avoid certain forms of ISP traffic shaping, but that should not be assumed.
Why does a VPN increase ping?
A VPN can increase ping because your data has to travel to the VPN server first. Nearby servers may add only a small delay, while long-distance servers can add much more latency because the traffic has to cross more physical distance and network hops.
Which VPN server is fastest?
The fastest VPN server is usually one that is geographically close, not overloaded and supported by a modern protocol such as WireGuard or a provider's WireGuard-based option. For streaming from another country, the best server is often a balance between location, speed and reliability.
Can a VPN affect streaming quality?
Yes, but mainly when the VPN connection is too slow or unstable for the video quality you want. A fast VPN server can handle HD and 4K streaming comfortably, while a distant or overloaded server may cause buffering, lower resolution or longer loading times.
How do I stop a VPN slowing my internet down?
Use a nearby server for normal browsing, switch to a modern protocol, avoid overloaded locations, test both Wi-Fi and wired connections, restart the app if speeds collapse and use split tunnelling for apps that do not need the VPN.
