Example calculations

Tap an example to prefill the calculator with sample values.

WireGuard regional server

250 Mbps line on a modern device

A practical case where the protocol is efficient and the server is not too far away.

Result: The line should still be more than fast enough for 4K streaming and general browsing.

OpenVPN on older hardware

Bigger overhead from protocol and device CPU limits

This catches the common case where the VPN protocol and hardware both compress usable throughput.

Result: Overhead compounds quickly once the protocol and hardware are both less efficient.

Far-away server route

Strong base line, but long geographic route

Useful when unblocking a far library or region-specific service is the reason for the VPN session.

Result: Distance can dominate the latency side even when the raw line speed is good.

Gaming VPN — FPS competitive

30ms base ping, WireGuard local, FPS game

Tests whether a VPN is viable for competitive FPS play where ping sensitivity is highest.

Result: WireGuard on a local server typically stays under 50ms — acceptable for competitive FPS with DDoS protection.

How the VPN overhead estimate works

The calculator starts with a protocol-level speed and latency penalty, then layers on route distance and a small device-class adjustment to reflect encryption overhead and longer network paths.

It is intentionally directional rather than exact. The point is to compare likely tradeoffs between protocols and server choices before you connect.

VPN overhead FAQs

Use it for planning, not as a benchmark replacement for a live speed test.

Why does protocol choice matter so much?

Different VPN protocols have different encryption and transport overhead. WireGuard is usually lighter, while OpenVPN TCP is often slower and adds more latency, especially on weaker devices.

Why include server distance separately?

Because even an efficient protocol cannot avoid physics. A much longer route adds latency and can also reduce throughput depending on peering and congestion.

Is a VPN good for gaming?

It depends on the game type and VPN protocol. WireGuard on a local server typically adds 10–15ms, which is acceptable for most games. FPS and Battle Royale titles are the most ping-sensitive, while MMOs tolerate more latency. The main gaming benefit is DDoS protection for streamers and competitive players.

Does a VPN reduce ping?

Almost never. A VPN adds an extra network hop which increases latency. In rare cases where ISP routing is suboptimal, a VPN can improve routing, but for most users ping goes up. The calculator shows the expected increase based on your protocol and server distance.
