transfer time ▸ explained

What you need
to know.

Estimate how long a file, backup or server migration takes at a given connection speed.

bits vs bytes

Speeds are in megabits; files in megabytes. 100 Mbps moves about 12.5 MB per second at best.

overhead

TCP/IP, TLS and disk speed typically eat 10–20%. We apply your chosen efficiency.

migration

Moving 500 GB over 100 Mbps takes ~12 hours — schedule it overnight or ask us for a free migration.

How long does it take to transfer 1 TB?+

About 2.5 hours at 1 Gbps or roughly 25 hours at 100 Mbps, assuming 90% efficiency.

Why is my download slower than my plan speed?+

Server limits, Wi-Fi, distance and protocol overhead all reduce real throughput. The calculator's efficiency slider models this.

Does The PowerHost migrate sites for free?+

Yes — website migrations to our hosting are free. Our team moves files, databases and email for you.
