Download time depends on file size divided by transfer speed. Real speeds can be lower than advertised connection speeds.
Internet plans are often quoted in megabits per second, while file sizes are often shown in megabytes or gigabytes. Mixing those units is the most common download-time mistake.
The estimate is best-case if the entered speed is stable. Real downloads can slow because of Wi-Fi, congestion, the server or other devices using the same connection.
If the download affects a schedule, use time calculators to plan the finish window.
