How Much Data Can 100 Mbps Transfer Per Day?

A 100 Mbps connection can theoretically transfer 1.08 TB in 24 hours at continuous full utilization.

The calculation

100 Mbps ÷ 8 = 12.5 MB/s. Across one day, that equals 1.08 TB using decimal units.

Real-world planning

At 90% sustained efficiency, capacity is about 972 GB/day; at 80%, about 864 GB/day.
