Estimate the internet bandwidth your business needs based on team size, usage patterns, video conferencing, and cloud services.
| Team Size | Light Usage | Standard Usage | Heavy Usage | Power Usage |
|---|---|---|---|---|
| 1–10 | 30 Mbps | 80 Mbps | 150 Mbps | 300 Mbps |
| 11–25 | 60 Mbps | 150 Mbps | 350 Mbps | 600 Mbps |
| 26–50 | 120 Mbps | 300 Mbps | 700 Mbps | 1 Gbps+ |
| 51–100 | 200 Mbps | 500 Mbps | 1 Gbps+ | Leased Line |
| 100+ | 350 Mbps | 800 Mbps+ | Leased Line | Leased Line |

As a rough guide, allow 5 to 10 Mbps of dedicated bandwidth per user for typical office work including video calls, cloud apps, and email. A 20-person office doing regular video conferencing and using cloud services like Microsoft 365 usually needs 150 to 300 Mbps of reliable, symmetric bandwidth to avoid slowdowns.
Video conferencing and cloud backup are typically the heaviest consumers, each using 1.5 to 3 Mbps per active call or sync session. Large file transfers, VoIP calls, and streaming updates for cloud-hosted applications like SaaS platforms also add up quickly, especially when many staff are active simultaneously during core hours.
Generally yes, but not in strict proportion - bandwidth needs scale with concurrent usage, not headcount alone. An office where everyone is on video calls at 9am needs far more bandwidth than one where staff mostly do email and occasional cloud file access spread throughout the day.
Cloud applications like Microsoft 365, VoIP, and hosted line-of-business software generally need consistent, low-latency bandwidth rather than just high peak speed. This calculator estimates your required bandwidth based on user count and application mix, helping you check whether your current connection has enough headroom before performance issues appear.
