How Much Data Does Your Household Really Use in 2026?

According to OpenVault's Broadband Insights report, the average US home now runs through nearly 770 GB of data every month, and homes full of streamers, gamers and remote workers blow well past that.

The average US household uses about 767 GB of internet data per month, according to OpenVault's Q4 2025 Broadband Insights report up nearly 10% year over year. The median home uses around 532 GB, while roughly one in four households qualifies as a "power user," consuming 1 TB or more each month.

Most of us never stop to add it up. We hit play, jump into a match or join the morning standup, and the data quietly piles up in the background. This guide breaks down what each everyday activity actually costs in data, so you can figure out whether your plan fits the way your home really lives. Curious where you stand?

Data vs. speed: two different questions

Before the numbers, one distinction worth getting right: data and speed measure different things. Data, measured in gigabytes (GB), is how much internet your home consumes over a month, like the total water that flows through your pipes. Speed, measured in Mbps, is how fast it can flow at any moment, the water pressure.

Most “how much internet do I need" advice is really about speed. This guide tackles the other half of the question, the one that decides whether you hit data caps and overage fees: how many gigabytes your household actually goes through. When you are ready to size the speed itself, our guide to how much internet speed you really need has that covered.

How much internet does the average household use?

Home internet use has been climbing for years and it is not slowing down. In the final quarter of 2025, average monthly data use crossed 700 GB for the first time, landing at about 767 GB per household, according to OpenVault's Broadband Insights report.

That is up nearly 10% in a single year. The typical (median) home used about 532 GB, and roughly one in four households now counts as a power user, chewing through a full terabyte or more every month.

What's driving the jump? More screens, more 4K, more video calls and a lot more connected gadgets. The average US internet home now juggles around 17 connected devices, from phones and TVs to doorbells and thermostats, per Parks Associates. Each one sips a little bandwidth, and together they add up fast. The real takeaway: your internet diet isn't one big meal, it's hundreds of small bites all day long. And it keeps climbing: OpenVault's mid-2026 reading puts the average at 711 GB a month, up 7.1% in a year, so the number you plan around next year will be bigger than today's.

What uses the most data at home?

Not all activities are created equal. Streaming video and video calls are the heavy hitters, while live gaming and browsing are lighter than most people expect, at least until someone starts a big download. Here's a rough look at how common activities stack up.

The pattern is clear: video is where the gigabytes go. One 4K movie night can outweigh a whole week of online gaming, and every extra person and screen multiplies the total, because each stream pulls its own data at once.

How much data does streaming use?

Streaming is almost always the biggest line item in a home's data diet. According to Netflix, watching in standard definition uses about 0.7 GB per hour, high definition jumps to roughly 3 GB per hour, and 4K Ultra HD can hit around 7 GB per hour. So one two-hour movie in 4K can eat about 14 GB by itself, while the same film in HD is closer to 6 GB.

YouTube, Disney+ and the rest land in the same ballpark, because resolution is what really drives the cost. Picture a normal evening: a 4K show in the living room, a teen streaming HD upstairs and a phone playing video in the kitchen. Three streams, easily 12 to 15 GB in a couple of hours.

If your home leans into 4K on multiple screens, this one category can push you toward, or past, that 700 GB average on its own.

How much data does gaming use?

A few data hogs rarely make it into the mental math. Short-form video is one: TikTok burns through roughly 840 MB per hour at default quality, and about 1.5 GB per hour at 1080p, so a scrolling habit across two or three phones can quietly rival a nightly Netflix stream.

Smart cameras are another. A single cloud security camera can upload 30 to 100 GB a month at 1080p, and a Nest camera on medium settings runs about 60 GB a month, before you add a video doorbell.

That points to the bigger shift: what your home sends is growing faster than what it pulls down. OpenVault reports upstream traffic climbing about 20% year over year, roughly three times the pace of downloads, driven by video calls, cloud backups and camera uploads. Data flows both ways, and the up direction is the one to watch.

Three household internet profiles

Averages only get you so far. Here's how the math shakes out for three very different homes.

The streaming family

Two parents, two kids, several TVs and a stack of subscriptions. Between after-school cartoons, evening 4K movies and weekend binges, this home runs multiple HD and 4K streams at once for hours a day.

• Estimated monthly usage: 600 GB to well over 1 TB
• Plan fit: Several simultaneous 4K streams need real headroom and unlimited data; size the exact tier with our Internet speed guide.

The remote work household

One or two people on back-to-back video calls all day, plus cloud file syncing and the usual evening streaming. Video meetings run about 1 to 2.5 GB per hour each, per Zoom, and upload speed matters as much as download when you are the one on camera.

Estimated use: 300 to 600 GB a month. Plan fit: prioritize strong, symmetrical upload (a fiber strength) so your video stays crisp on both ends; our speed guide covers the sizing.

The gamer's den

One or two avid gamers, frequent large downloads and maybe some live streaming to an audience. Live play is light, but a few 100-plus GB downloads in a month change the picture in a hurry.

Estimated use: 200 to 500 GB, spiking on big release weeks. Plan fit: downloads this size reward faster tiers and low latency, and unlimited data covers big release weeks; see our speed guide to pick the tier.

How to turn your data usage into the right plan

Data tells you how much you use. Speed tells you how much you can do at once. Match your monthly gigabytes to a usage band, then let our dedicated speed guides handle the sizing:

• Light (under 300 GB a month): browsing, email and a little streaming on a screen or two.
• Moderate (300 to 600 GB): a few HD streams, daily video calls and casual gaming.
• Heavy (600 GB to 1 TB): multiple 4K streams plus remote work and gaming at the same time.
• Very heavy (1 TB and up): a full house of simultaneous 4K, big downloads and smart home gear running nonstop.

Plan for everyone doing their thing at the same time, not one at a time. For the actual speed recommendations, lean on our dedicated guides: how much speed do you need and what counts as a good internet speed. Connected-home setups have their own needs too, covered in our smart home bandwidth guide. Usage bands are estimates; individual households vary.

How to check how much data your household actually uses

You do not have to guess. Three quick ways to get your real number:

1. Your provider's app or portal. Optimum customers can see every connected device on their network in the My Optimum app; providers that impose data caps typically show a monthly usage meter in the account dashboard.
2. Your router's admin dashboard. Most modern routers and mesh systems break down usage per device, the fastest way to spot a surprise data eater.
3. Per-device settings. Phones, consoles and smart TVs each report their own usage, handy for confirming who the heavy hitter really is.

Check it for two or three months and you will know your baseline better than any national average can tell you.

Does your current plan match your household's usage?

Once you know roughly how your home eats up data, compare it to what you are paying for. Two questions matter most. First, do you have enough speed for everyone at once? The FCC now defines broadband as at least 100 Mbps download and 20 Mbps upload, a useful floor when sizing up your plan.

If videos buffer when the house is busy, your plan can't keep up with your peak. Second, are you bumping into a data cap? Some providers add overage fees or slow you down after a limit, turning a heavy streaming month into a surprise bill.

This is where the fine print pays off. Every Optimum Internet plan comes with unlimited data and no data caps, so a 4K movie marathon or a 150 GB game download won't cost you extra or throttle your speeds. Fiber plans also deliver symmetrical speeds, meaning uploads keep pace with downloads, a real plus for video calls and cloud backups.

Frequently Asked Questions (FAQs)

How much internet does the average household use per month?

As of late 2025, the average US home used about 767 GB of data per month, the first time the average has crossed 700 GB, according to OpenVault's Broadband Insights report. That figure is climbing roughly 10% a year, and about one in four homes now uses a full terabyte or more every month.

How much data does streaming use?

It depends on resolution. Per Netflix, standard definition uses about 0.7 GB per hour, HD about 3 GB per hour, and 4K Ultra HD around 7 GB per hour. A single two-hour movie in 4K can use roughly 14 GB on its own, and every simultaneous stream adds to the total.

How much data does gaming use?

Live online play is surprisingly light, usually 40 to 300 MB per hour, often around 100 MB, which is less than 20 minutes of HD streaming. The data hogs are downloads and updates: a single modern game can run 50 to 150 GB, and cloud gaming streams like 4K video at several GB per hour.

How much data do video calls use?

An HD video call uses roughly 1 to 2.5 GB per hour and needs about 3 to 4 Mbps to run smoothly. Group calls use more than one-on-one calls. Upload speed matters as much as download here, since you are sending your own video at the same time.

How do I know if my internet plan is enough?

How do I know if my internet plan is enough?

Two quick checks. First, does anything buffer or freeze when the whole house is online at once? That is a sign your plan cannot handle your peak. Second, are you hitting a data cap or overage fees? If either is true, it is time to upgrade. Run a speed test and compare the result with how your household actually streams, works and games.

What is the difference between internet data and internet speed?

Data, measured in GB, is how much you consume over the month; speed, measured in Mbps, is how fast it moves at any instant. A fast plan can still hit a data cap, and an unlimited-data plan can still feel slow at peak hours. They are separate questions, so size your data with this guide and your speed with a dedicated speed guide and a quick speed test.

The bottom line

Your home's internet needs aren't about any single device, they're about everything running together. Stack a few 4K streams on a workday of video calls and a big game download, and an average connection can feel anything but.

The good news: once you know your data diet, picking the right plan gets simple. Test your speed, map it against how your household plays, works and streams, and choose a plan with the headroom, and the unlimited data, to handle it all.
