Bandwidth Required Calculator

Know how much data you need to move and how much time you have? Calculate the theoretical minimum network bandwidth required to finish within that window.

Data to transfer

Transfer window (hours)

277.778Mbps

Theoretical minimum bandwidth. Allow headroom for real-world overhead and other traffic.

Planning a backup window

This is useful when sizing links for backups, migrations and large data transfers. For production planning, add headroom because protocol overhead, congestion, storage speed and competing traffic can reduce effective throughput.

Formula

Required bandwidth = data size in bytes × 8 ÷ available seconds.
