Internet connection speed calculator

Do you want to to know the speed of your Internet connection what have you contracted? When you see an advertisement on television offering, for example, a download speed of 300 Mbps, you must bear in mind that what they are selling you is 300 Megabits (Mb) per second and not 300 MegaBytes (MB).

The differences between both units are very palpable when downloading files, music or movies over the Internet since these files are in KiloBytes, MegaBytes or GigaBytes. Below you have a calculator that we have designed for you to know the download or upload speed of your connection to the Internet from the data you have contracted. 

Does the data correspond to the Internet connection you have contracted?

Internet speed test

Now that you have calculated the theoretical speed of your Internet connection, it is highly recommended that you do a speed test to check if the data obtained is close to what you have contracted.

With the speed test you can calculate the download and upload speed of your Internet connection.

Note that the data obtained by speed test will be lower than the theoretical data obtained with our Internet speed calculator. How much lower? It depends on many factors but the most influential are the following:

  • If you have a fiber or ADSL connection. In the latter there is a lot of signal attenuation and the copper pair can reduce the speed of your connection if it is in bad condition.
  • Whether you are connected to the router by cable or by WiFi. If you use a wireless connection, get as close as possible to the access point so that distance is not another factor that slows down your connection speed.
  • Close data-consuming applications in the background. If you are downloading any movies or music, using youtube, etc. Close all those tasks before starting the speed test or you will get false results. You should also make sure that no other devices are connected to your connection and are consuming bandwidth.
  • Distance from your home to the supplier of services. This is something that has a greater influence in the case of ADSL because of what we have mentioned in the first point. If you have fiber, the attenuation is much less and the signal reaches your home practically in its entirety, so you will almost certainly have the speed you have contracted.

If still Internet is very slow and the speed test differs a lot from the results obtained with our calculator, then call your operator and ask for an explanation because they are not complying with the conditions agreed in the contract.

How to calculate the speed of your Internet connection?

Internet connection speed

Let's take an example. Imagine that your connection is 20 Mbps downstream and 600 Kbps upstream. upload speed. You enter this data into the calculator and you will see that you can download files at a maximum speed of 2.38 MB/s and get an upload speed of 73.24 KB/s.

Of course, these values are theoretical so it is likely that you will actually get much lower results. This is due to multiple technical factors such as the condition of the cabling, the distance from your home to the service provider (if you are using fiber, to the FTTH point), etc.

Even so, it can be useful as a guideline in case you are thinking of changing operator and want to get an idea of the speed that your Internet connection could reach.
