How Much Data Does a VPN Use?
Using a VPN adds a small amount of data "overhead" to your internet usage due to the encryption process. While usually minor, this can add up over a month, especially on a mobile data plan. This calculator helps you estimate your total monthly data consumption while using a VPN by factoring in this overhead.
Frequently Asked Questions
What is VPN overhead?
VPN overhead is the extra data used by the VPN protocol for encryption and encapsulation. Every data packet you send is wrapped in another packet, which makes it slightly larger. This overhead is typically between 5% and 15%, depending on the VPN protocol (e.g., WireGuard is more efficient than OpenVPN).
How can I estimate my base data usage?
You can use our main Data Usage Calculator to get a good estimate. For a rough idea: light browsing is ~0.15 GB/hour, HD video streaming is ~3 GB/hour, and 4K streaming is ~7 GB/hour.
