The Federal Communications Commission (FCC) defines broadband internet with a minimum download speed of 25 Mbps and 3 Mbps of upload speed. Therefore, 100 Mbps internet may be considered a fast speed by some users. Typically, a 100 Mbps internet speed plan can support an average American household, where 2 to 5 devices are connected simultaneously, engaging in activities like video conferencing and HD streaming.

However, when smart homes and home offices come into the equation, 100 Mbps internet speed may not sound like a lot. Ultimately, how fast you consider an internet speed to be depends on how you use the internet and how many devices you have.

If you are wondering whether 100 Mbps is fast, your answer lies in the your household’s consumption of the internet. To simplify the matter for you, our guide determines if 100 Mbps is fast for you and distinguishes what speeds qualify as “fast internet”.

Defining a Good Internet Speed

Most people are seeking a “good internet speed” for their household, without fully understanding what a good internet speed could mean for them. A 5 Mbps internet speed may be considered good enough for single-person use who just wants the internet for casual browsing and SD video streaming (3 Mbps per device).

Whereas, a 25 Mbps internet speed may be what makes the cut as “good internet speed” for a household with 4 internet users engaging in activities like checking emails (1 Mbps per device), streaming videos in HD (5-8 Mbps per device), and social networking (3-5 Mbps per device).

100 Mbps internet is an excellent speed for gaming (3-6 Mbps per device), 4K streaming (25 Mbps per device), and video chatting (1-6 Mbps per device) — all simultaneously! And even more, 100 Mbps internet speed is not the highest speed tier out there. In fact, providers like AT&T and Xfinity offer multi-gig internet speeds of up to 5 or 6 Gig!

However, internet that fast may not be a necessity for gaming and video conferencing. In fact, with only 2 or 3 devices connected to the internet, a speed lower than 100 Mbps may suffice too!

So, the answer to the million dollar question – what is a good internet speed – is not any specific number. It is instead based on how many devices are connected and how the internet is being used. Here is a quick look at some estimates of how much internet speeds are required by various online activities:

Internet Speed Number of Devices Activities

25 to 40 Mbps

2 to 4

Basic web browsing, checking emails, social networking, SD video streaming

40 to 100 Mbps

4 to 6

Streaming in HD, occasional video chatting, sharing mid-size media files

100 to 500 Mbps

6 to 8

4K video streaming, basic gaming, video conferencing, working from home, basic smart home devices

500 Mbps or above

10 or above

Advanced smart homes, cloud computing, 4K gaming, 4K streaming, heavy media file sharing

How Fast Is 100 Mbps Internet Speed?

100 Mbps internet is pretty fast. If we consider the FCC’s broadband internet definition, 100 Mbps internet is 4 times faster than the basic broadband download speed. So, while a 100 Mbps internet plan may sound fantastic in theory, you might need to look into some other factors before deciding whether the speed is right for you.

Firstly, depending on your household’s internet usage and device count, the 100 Mbps internet speed may prove to be more, less, or just right. For instance, if you have a smart home with devices like security cameras, thermostats, and speakers, each using up to 10 Mbps, your 100 Mbps plan may get strained. On the other hand, the same speed tier may end up being a bit excessive for a small household engaged in basic online activities like casual browsing, emailing, or streaming music.

So, how do you determine whether 100 Mbps is fast internet speed for you?

Consider the general estimate that the 100 Mbps internet plan can accommodate data-intensive activities for 3 to 4 users very easily. Some of these activities include HD and 4K streaming, gaming, and video conferencing. It is a highly recommended speed tier if you work remotely or share heavy media files online.

However, if you are a stickler for accuracy, consider using an online tool to obtain a precise answer. The BuyTVInternetPhone Speed Calculator will determine if the 100 Mbps speed tier is suitable for your household and provide customized recommendations as per your zip code.

Secondly, take into account the quality of your internet equipment. Make sure the modem and router have updated firmware and are fully compatible with your internet connection to ensure optimal performance. In addition to this, place your equipment in a strategic location to ensure sufficient signal coverage for all your devices. Plus, adjust your router settings to utilize the best channel and frequency for your network.

Thirdly, a 100 Mbps internet plan does not necessarily mean you will be able to enjoy the exact download speed in reality too. The speeds received by your devices actually are affected by several external factors, such as possible viruses and malware, background processes, poor signal coverage, and outdated devices. Therefore, it is essential to investigate what might be impacting your internet speed and take steps to minimize those effects.

Asking the right questions will help you determine whether 100 Mbps is a speed fast enough for you!
