Assumptions and estimates

  • Distinguishes decimal GB from binary GiB and megabits/second from bytes. Efficiency allows for protocol/connection overhead; simultaneous traffic, throttling, server limits and latency can lengthen actual transfers.
  • Method: Transfer seconds = file bytes × 8 / (link Mbps × 1,000,000 × throughput efficiency).
  • Editable inputs are planning assumptions; check the method and result notes for scope.

How the file transfer & download time calculation works

Transfer seconds = file bytes × 8 / (link Mbps × 1,000,000 × throughput efficiency).

Editable inputs are planning assumptions; check the method and result notes for scope.

Using this calculator

  1. Enter your own figures in the labelled inputs. Keep the currencies, units and time periods consistent.
  2. Choose any applicable rate profile, pattern or assumption shown for this tool. Open additional inputs when relevant.
  3. Review transfer minutes and effective mbps, then read the stated assumptions and eligibility conditions before using the result.
