Internet Speed Requirements for Remote Work
Tell us your video stack and household. We'll tell you exactly how much Mbps up and down you need, plus a verdict on whether your current ISP plan is enough.

For context:
- FCC fixed-broadband benchmark is 100/20 Mbps (March 2024).
- US median speed is around 285/49 Mbps (Ookla 2025).
- Latency < 150 ms and jitter < 30 ms matter more than raw Mbps once you're above ~25 Mbps.
Show per-app bandwidth math
Bandwidth numbers sourced from Zoom Help Center (official tables), Microsoft Teams Prepare Your Network, Google Meet network requirements, Cisco Webex bandwidth article, Slack Huddles network configuration, and Netflix recommended speeds. Recommendations include 20% protocol overhead and a Wi-Fi efficiency factor (real Wi-Fi delivers ~70% of advertised throughput in mixed-use households).
How much internet speed you actually need
The published "minimum" numbers from Zoom, Teams, and Google Meet are honest but optimistic. They describe the bare-floor bitrate the protocol needs in a clean lab, not what works on your living-room Wi-Fi when your spouse is also on a call and a kid is streaming Netflix in 4K. This calculator factors all that in.
Why upload speed is the real constraint
Most home internet is asymmetric - you get a lot more download than upload. A typical 100 Mbps cable plan only delivers 10 Mbps up. That's fine for watching Netflix but borderline if two people in the household are on simultaneous video calls. For remote work, upload speed is the number to watch. Fiber and 5G home internet usually deliver symmetric (or near-symmetric) speeds; cable plans below ~300 Mbps down rarely do.
Why latency matters more than raw Mbps
Past about 25 Mbps each way, raw bandwidth stops being the bottleneck for video calls. What starts to matter is latency (round-trip ping time, ideally under 150 ms) and jitter (variation in latency, ideally under 30 ms). A 50 Mbps fiber connection with 8 ms ping will outperform a 1,000 Mbps cable connection with 60 ms ping for video calls. Run a test at speed.cloudflare.com to see all three numbers (down, up, latency, jitter).
VPN and the 25% rule
Corporate VPNs encrypt and tunnel everything, which adds protocol overhead. Plan for about 25% extra upload demand when you're on a VPN, especially if your work involves screen sharing or large file transfers. The calculator factors this in if you tick the VPN toggle.
