How much bandwidth do I need?

Estimate concurrent users, multiply by the Mbps each needs for their main application, then add headroom. This calculator automates that pattern for study and small designs.

How do I calculate network bandwidth?

Required Mbps ≈ users × concurrency fraction × per-user Mbps × (1 + overhead). Adjust the per-user figure for web, voice, or video workloads.

How much bandwidth does video conferencing use?

SD calls often sit near 1-1.5 Mbps per stream. HD calls commonly need about 2-3 Mbps, and HD with screen share can reach ~5 Mbps. Use the presets, then confirm with your vendor’s guidance.

How do I calculate bandwidth for multiple users?

Do not multiply as if everyone peaks at 100% unless that matches reality. Apply a concurrency percentage so idle users do not inflate the circuit size.

What is the difference between bandwidth and speed?

Bandwidth is capacity (how much data the path can carry). Speed describes how quickly a transfer finishes for a user. Congestion appears when demand exceeds bandwidth.

What is Bandwidth Calculator?

A free online tool that estimates network capacity from users, per-user demand, concurrency, and overhead for learners and admins.

How does the Bandwidth Calculator work?

It computes concurrent users, multiplies by Mbps per user, applies overhead, and rounds up to a practical recommended capacity.

How do I use the Bandwidth Calculator?

Fill in users, Mbps per user, concurrency, and overhead, or pick an application preset, then read the recommended Mbps or Gbps figure.

Is this Bandwidth Calculator free to use?

Yes. It is free for home networks, IT students, and network administration planning exercises.

Can I use the Bandwidth Calculator on mobile?

Yes. The calculator works in mobile browsers for quick capacity checks.
