Does a VPN Slow Down Your WiFi?

A VPN adds some overhead — but a good one on a fast connection is barely noticeable. Here's what to expect and how to minimise the impact.

Updated 2026

  1. 1

    Why a VPN slows things down

    A VPN encrypts every packet and routes it through an extra server before it reaches its destination. Encryption takes CPU time; the extra hop adds distance and latency.

  2. 2

    How much speed you lose

    A quality paid VPN (Mullvad, NordVPN, ExpressVPN) on a 100Mbps connection typically costs 5–20% speed. Free VPNs can be 50–80% slower due to overcrowded servers.

  3. 3

    Reduce VPN speed loss

    Connect to a server close to your physical location. Use WireGuard protocol if your VPN supports it — it's significantly faster than OpenVPN. Avoid free VPNs.

  4. 4

    When VPN makes no difference

    For browsing and streaming at HD quality, a 10–20% speed reduction is invisible. The impact only matters for large downloads or if your base speed is already low.

Frequently Asked Questions

Does a VPN affect ping in gaming?
Yes — a VPN routes traffic through an extra server, which adds latency. For gaming, turn the VPN off unless you specifically need it (e.g. to avoid ISP throttling of game traffic).
Can a VPN actually speed up my connection?
Occasionally — if your ISP throttles certain traffic types (streaming, gaming), a VPN can bypass this and give faster effective speeds for those services.
