Desire to find out how long a download might have? Because a broadband upgrade and want to meet how much faster your net speed could exist?

In this guide, y'all can use our download time figurer to go an instant estimate of how long a transfer will take and learn more about downloading and uploading and improving your download speed.

Broadband download fourth dimension and speed calculator

Use the calculator widget below to find out how long a download will take.

Enter the size of the download in bytes (kilobytes, megabytes, gigabytes, etc.) and the speed of your broadband connexion in bits (about likely megabits). Click the drop-downward menus to switch between kilo/mega/giga and seconds/minutes/hours.

Use our free speed test to notice out your broadband speed.

You can also enter a time and file size to guess the speed of a broadband connection, or a fourth dimension and speed to get a file size.

How is download time calculated?

The equation for computing download time is:

File Size in bytes / (Download Speed in bits / 8) = Fourth dimension

For instance:

50MB / (10Mb/8) = forty seconds

Of grade, it's much simpler to apply the calculator above, especially when you get into the hundreds or thousands of megabytes.

What's the difference betwixt bits and bytes?

Bits and bytes are both units of data, but they're used in dissimilar ways for broadband.

Data transfer speed is measured in bps — bits per second. Most broadband speeds volition be shown as megabits per second (Mbps, Mb/s, or Mb), though kilobits (Kbps, Kb/s, or Kb) and gigabits (Gbps, Gb/s, Gb) are also common.

Bytes are used to indicate data size or chapters, like the size of a file or a difficult bulldoze's storage space.

There are eight bits to every byte. So a 1 megabit internet connection can transfer one megabyte every 8 seconds.

Upper and lower case is used to differentiate between them; small b for bits (Kb, Mb, Gb), big B for bytes (KB, MB, GB).

What broadband download speed practice I need?

Your broadband speed requirements will depend on what yous plan to practice with the broadband and how many people share the connection.

Frequent large file downloads or uploads are much easier with fast internet; the table below shows how long files of various sizes tin can take to download and illustrates how much of a difference fibre broadband makes.

File size	Broadband speed
	10Mb	35Mb	50Mb	65Mb	100Mb	500Mb
1GB	13.3 mins	three.8 mins	two.6 mins	ii.1 mins	1.3 mins	16 secs
10GB	2.two hours	38.1 mins	26.6 mins	20.v mins	xiii.iii mins	2.6 mins
50GB	eleven.1 hours	3.2 hours	two.2 hours	1.vii hours	1.1 hours	thirteen.3 mins
100GB	22.two hours	vi.4 hours	four.4 hours	iii.4 hours	two.2 hours	26.6 mins

As yous tin see, even a cheap entry-level fibre optic deal with an average speed of 35Mb will significantly reduce download times compared to a 10Mb ADSL service.

Video streaming also benefits from faster broadband speeds equally it will let you lot stream in loftier-quality HD and ultra HD. Without information technology, you may discover viewing is oft interrupted by buffering.

The other gene to consider is how many people will be sharing the connection considering every person (or device) you add will reduce the bachelor bandwidth.

ADSL broadband (which has an boilerplate speed of only 10Mb) can struggle to cope even with fairly calorie-free usage if more than one person is online at the aforementioned time.

Fibre optic cyberspace is essential for shared or family homes. As a crude guide, let a speed of 10Mb per person, plus another 10Mb for every person who is probable to be using information technology for things like file downloads and video streaming.

Notwithstanding, we recommend a minimum of 35Mb fibre optic broadband for everyone, even if you're the only person using the internet. With this speed, you can easily stream Hd video and download files in a reasonable fourth dimension. And at that place are enough of cheap fibre optic deals bachelor, so it'south non much more expensive than ADSL.

How can I calculate upload time speed?

Calculating the time of an upload (where files are sent from your device to the cyberspace) is the same as working out a download time, except y'all'll most likely have to change the speed.

Most broadband services have a slower upload speed in favour of quicker downloads (this is known as asymmetrical broadband). Some broadband is symmetrical, which ways it has the aforementioned download and upload speed, but this is rarer.

Use our broadband speed test to find out your current upload speed.

Why are my downloads and uploads taking longer than calculated?

The figurer shows the time information technology will take to transfer files at any given speed, just your connection will non continuously move data at the same charge per unit. Speeds can fluctuate fifty-fifty during a transfer, and the performance of your broadband will change throughout the day depending on network traffic.

The speed can also be restricted by the connection of the server that is sending or receiving information. If a server is very busy, yous will find that speeds are reduced as a result, fifty-fifty if your broadband connectedness appears to be working normally.

How to get faster download speeds

If your downloads are slower than expected, here are a few things y'all tin can do to improve the speed.

Switch off other devices and software on your Wi-Fi
Other devices sharing your broadband may be impacting the speed by reducing the bachelor bandwidth. Switch off anything yous don't need to free up more bandwidth for your download.

Download from a different server
Sometimes a deadening download is caused past the server sending you the file rather than your broadband connectedness, so try getting the file from another site. If possible, cull a server close to your location.

Save big downloads for off-superlative hours
Broadband networks tin tedious down during peak hours (typically 8am to midnight). Await until late at dark or early in the morning time, and yous might find the transfer is completed much sooner.

Employ a wired network connectedness
Wired networks tin be faster and more reliable than Wi-Fi, so it'southward preferable to connect your devices directly to the broadband router with a network cable if you need faster speeds.

Boost your Wi-Fi signal
If a network cablevision isn't an option, at that place are ways you lot can improve Wi-Fi signal strength to get ameliorate speeds. Wi-Fi extenders are a cheap mode to heave the bespeak in areas of your home where the network is weak. You should as well ensure that the Wi-Fi router is in a key location in your home and is not close to whatever walls or appliances which may block the bespeak, especially fridges, microwaves, and cordless phones.

Reboot the Wi-Fi router
If your broadband is unusually boring and you've eliminated other causes, effort switching it off and on. Frequently, power cycling your router to reconnect it to the network will improve broadband performance. This volition disconnect every device on your Wi-Fi network while it reboots, and then bank check with everyone in your home first.

Upgrade your broadband
If there's no way to amend your electric current broadband service, information technology may be time to consider upgrading to a faster parcel.
