Count only what runs at the same time in your busiest hour. Download figures are the FCC’s minimums for one activity each, added together; upload for calls uses Zoom’s 1080p group-call figure. The FCC notes that extra speed can improve performance.

25 MbpsFCC minimum for one 4K stream
5–8 MbpsFCC range for one HD stream
6 MbpsFCC figure for HD video meetings
3.8 MbpsZoom upload for a 1080p group call

Quick answer

Add up what your household runs at the same time, then use the FCC’s minimum for each activity: 1 Mbps for browsing, 5 to 8 Mbps per HD stream, 25 Mbps per 4K stream, 6 Mbps per HD video meeting and 4 Mbps per online game. A home with two 4K streams, two video calls, one gamer and three phones browsing lands at about 69 Mbps of download. The calculator above does that sum for you.

The FCC’s figures are minimums for one activity at a time, so the calculator adds them for everything you count. Set the rows to your busiest hour, usually the evening, not to the number of devices you own.

How the calculator gets its number

Each row multiplies the number of things running by the FCC’s download minimum for that activity, and the rows are added together. Where the FCC gives a range, like 5 to 8 Mbps for HD video, the big number uses the top of the range and the low end is shown underneath. The FCC says its numbers are rough guidelines and that additional speed may improve performance, so treat the result as a floor to shop above, not a target to match exactly.

The household tier comes from the FCC’s Household Broadband Guide, which groups homes into Basic service (3 to 8 Mbps), Medium service (12 to 25 Mbps) and Advanced service (more than 25 Mbps) by how many people are online and how heavy their use is.

Four households, run through the calculator

Here is what the calculator gives for four common setups, counting only what runs at the same time in the busiest hour:

Household at its busiest	Download (FCC low to high)	Upload for calls
One person, working from home on Fridays: phone and laptop browsing, one HD stream, one video meeting	13 to 16 Mbps	3.8 Mbps
Two people both on video meetings, two phones browsing, cloud sync running	24 Mbps	7.6 Mbps
Family of four in the evening: four phones, two 4K streams, one HD stream, one online game	63 to 66 Mbps	none counted
The same family while a game update downloads and a second player joins	77 to 80 Mbps	none counted

Every one of these fits under the FCC’s own broadband benchmark of 100 Mbps down and 20 Mbps up, which the agency adopted in March 2024. That matches what people who run home networks tend to tell each other. On r/HomeNetworking, a 76-upvote reply in 2026 put it as “The vast majority of people would be satisfied with 300Mbps.” Plans far above 300 Mbps mostly shorten big downloads; they don’t make streaming or calls smoother.

One r/HomeNetworking thread from July 2026 is a good real-world test. A household of five, three of them children, normally on 2 Gbps fiber, ran on a 100 Mbps backup line for about five days after a storm cut the fiber. The poster wrote that only he noticed, because he saw the router switch over; the rest of the family kept browsing and streaming as usual. That is the calculator’s point in practice: what a home runs at once rarely adds up to the big plan numbers.

The column people skip is upload. Two people on video meetings already need about 7.6 Mbps up by Zoom’s figures, and a cable plan that sells a large download number can come with a small upload number. Check both before you sign.

FCC minimum download speeds by activity

These are the figures the calculator uses, from the FCC Broadband Speed Guide.

Activity	Minimum download
General browsing and email	1 Mbps
Social media	1 Mbps
Streaming online radio, VoIP calls	Less than 0.5 Mbps
Standard definition video	3 to 4 Mbps
HD video	5 to 8 Mbps
Ultra HD 4K video	25 Mbps
HD personal video call	1.5 Mbps
HD video teleconferencing	6 Mbps
Online multiplayer gaming	4 Mbps
File downloading	10 Mbps
Student, telecommuting	5 to 25 Mbps

Streaming services publish their own figures, and they can be lower. Netflix recommends 3 Mbps for 720p, 5 Mbps for 1080p and 15 Mbps for 4K. The calculator sticks with the FCC numbers because one household mixes several services.

Upload speed matters for calls and backups

Most home plans sell a big download number and a much smaller upload number. Downloads cover streaming and browsing; upload carries your side of a video call, photos syncing to the cloud and large files you send. The FCC guide only lists download speeds, so the calculator takes the upload figure for calls from Zoom’s bandwidth requirements: 3.8 Mbps up for 1080p HD group video, 2.6 Mbps up for 720p group video and 1.0 Mbps up for its standard high-quality group video.

If you back up a whole drive to the cloud, upload speed sets how long the first backup takes. The download time calculator works for uploads too: enter your upload speed instead.

Before you pay for a faster plan: a five-step check

Slow internet is often a Wi-Fi problem wearing a plan-speed costume. Ten minutes of testing tells you which one you have.

Test wired, next to the router. Plug a laptop into the router with a cable and run a speed test. This is the most your plan is delivering into the house.
Test again in the evening. Run the same wired test in your busiest hour. A number that is fine at noon and sinks at 8 pm points at the provider’s network, not your house.
Test in the room that buffers. Run it over Wi-Fi where the trouble is. If the wired number matches your plan and this room doesn’t, a faster plan won’t fix the room; better coverage will, and mesh Wi-Fi versus an extender walks through that choice.
Read the upload and ping lines too. If people on your calls see you freeze while their video looks fine to you, your upload is the weak side. Ping is the delay before data starts moving; a fast download with a high ping still feels laggy in games and calls.
Compare with the calculator. If your wired evening test is comfortably above the calculator’s number and things still stall, more Mbps won’t help. Restart the modem and router, test again, and take the wired results to your provider.

FAQ

Questions people ask

Is 100 Mbps enough for a family?

By the FCC’s per-activity minimums, 100 Mbps covers three 4K streams (75 Mbps), two HD video calls (12 Mbps) and a few devices browsing at the same time, with some left over. A household that streams more 4K at once, or runs big downloads during the evening, should count those in the calculator.

How much speed do I need to stream 4K?

The FCC lists 25 Mbps for one Ultra HD 4K stream. Netflix’s own help page recommends 15 Mbps or higher for 4K on its service. The calculator uses the FCC’s 25 Mbps so the number holds across services.

What upload speed do I need for video calls?

Zoom recommends 3.8 Mbps up for 1080p HD group video and 2.6 Mbps up for 720p group video. Upload is usually the smaller number on a home plan, so check it on your speed test, not only the download figure.

My speed test looks fine but some rooms are slow. Why?

A plan that tests well near the router but drops in far rooms is a Wi-Fi coverage problem, not a plan-speed problem. Test next to the router, then in the slow room, and compare.
