How Much Internet Speed Do I Need?
Describe your household and get an honest Mbps recommendation in seconds. No sign-up, no sales pitch from an internet provider: just the math.
How this calculator works
We add up what each activity in your home needs at the same time: about 25 Mbps per 4K stream, 8 Mbps per HD stream, 5 Mbps per video call or gaming session, 4 Mbps per cloud camera, and a few Mbps per person for everyday browsing. Then we add 25% headroom for peaks and round up to the plan sizes providers actually sell. Unlike a provider’s quiz, we have no reason to oversell you.

Speakers, plugs, bulbs, thermostats. They use little bandwidth individually, so a rough count is enough.
Recommended plan
100Mbps
These are download estimates assuming everything runs at the same time, plus 25% headroom for peaks. Remember: the plan you pay for is measured at the router. Weak Wi-Fi can make any plan feel slow in the back rooms.
Plan fast enough, but Wi-Fi still slow in parts of the house?
That is a coverage problem, not a plan problem. A mesh Wi-Fi system spreads full-speed coverage through the whole home and usually fixes it for good.

Common questions
Is 100 Mbps enough?
For 1 or 2 people who stream, browse, and take video calls, yes, comfortably. It gets tight when several 4K streams, downloads, and calls happen at once. Put your real household in the calculator above and you will see exactly where 100 Mbps stops being enough.
How much speed do I need for gaming?
Less than you think: online play itself uses about 5 Mbps. What ruins gaming is latency (ping) and a busy network, not a slow plan. The big numbers only matter for downloading games, where a 150 GB title on 100 Mbps takes over 3 hours but on 500 Mbps takes about 40 minutes.
How much speed do I need for 4K streaming?
Plan on about 25 Mbps per 4K screen. Netflix says 15 Mbps minimum, but real homes have other traffic in the background, so 25 per screen is the honest number that avoids buffering.
Why is my Wi-Fi slower than the plan I pay for?
Your plan speed is delivered to the router. From there, distance, walls, and an aging router eat into it, which is why the bedroom gets 40 Mbps on a 300 Mbps plan. If your plan is already fast enough on this calculator but rooms still crawl, the fix is better coverage (a mesh system or repositioning the router), not a pricier plan.
Do upload speeds matter?
For most homes, download does the heavy lifting. Upload matters if you make video calls all day, stream on Twitch, back up big files to the cloud, or run several security cameras. Cable plans often have small uploads (10 to 35 Mbps); fiber usually gives you the same speed both ways, which is a real advantage for remote work.
Do I need a gigabit plan?
Most homes do not. Gigabit shines for large households, heavy game downloaders, and creators moving big files. If the calculator recommends 300 or 500 Mbps, paying for 1,000 usually just means paying more for the same experience.
