What each row means
Each row estimates the same file transfer over a different connection rate using the selected real-world efficiency.
Compare one file size across common connection speeds and see how bandwidth changes total transfer time.
The table holds file size and efficiency constant so the effect of bandwidth is easy to compare.
Each row estimates the same file transfer over a different connection rate using the selected real-world efficiency.
Doubling usable throughput roughly halves transfer time when the connection remains the limiting factor.
The model does not know whether the source/destination server, storage device, Wi-Fi link or protocol imposes a lower ceiling than your selected connection speed.
For deadlines, choose an efficiency that reflects your real environment and leave margin for retries or changing network load.
0BPS SHOWS MEASURED OR CALCULATED FACTS SEPARATELY FROM INTERPRETATION. WHERE A RESULT IS ADVISORY, ESTIMATED OR DESTINATION-SPECIFIC, THE LIMIT IS STATED IN THE TOOL.
It applies one file size to several common connection speeds so you can compare transfer duration without recalculating each rate manually.
They are estimates. Real transfers can be slower because of protocol overhead, server limits, congestion, storage speed and Wi-Fi quality.
Calculator results are mathematical estimates based on the values you enter.
Protocol overhead, server limits and shared network activity can make observed results differ from the theoretical result.
Short examples using the same units and assumptions as this module.
Compare the same 25 GB file across 50, 100, 500 and 1000 Mbps without recalculating each rate.
