Bandwidth Calculator – Estimate Required Network Bandwidth
Use our free Bandwidth Calculator to estimate the total bandwidth needed for your users or devices. Accurate and easy to use
HD streaming, video calls, cloud file sync and social apps. Around 25 Mbps down and 5 Mbps up each.
Bandwidth is shared, so what matters is how many people are actually pulling data at the same moment - not the headcount.
Spare capacity for updates, backups and the days everyone is home. Sizing a line to exactly the average is how it ends up feeling slow.

Bandwidth is not the whole story
A line can have enough bandwidth and still feel slow. Latency, Wi-Fi coverage, an old router and the number of devices fighting for airtime all matter, and none of them are fixed by buying a bigger number.
