Bandwidth Calculator

Estimate required link capacity from concurrent users, per-user rate, and protocol overhead.

Required capacity550 Mbps
Raw bps550000000

How to read the result

Required capacity = users × per-user rate × (1 + overhead). Add headroom for bursts and retransmits.

Example

100 users × 5 Mbps + 10% overhead → 550 Mbps

FAQ

What overhead should I use?

10% is a common planning value for headers and retransmits; use 20-30% for video or lossy links.

Is this bits or bytes?

Rates are in bits per second (Mbps/Gbps). File sizes use bytes (MB/GB).
