# How Long Will My Download Take? Calculating Download Time

Calculate the time it will take to download a file depending on bandwidth / download speed. This video explains how to calculate how long it will take to download or transfer your file, dependent upon knowing the size of the file and the speed of the transfer. However this method can be adapted to calculate any transfer and apply it to real world problems. I explain the mathematics behind the simple formula of size / bandwidth = seconds of transfer. I also explain some of the considerations involved in the estimate of the transfer time.
