Internet Speed Needs Calculator
Count what your household does at once — 4K and HD streams, video calls, gaming, and smart devices — and get a recommended plan speed instead of overpaying for gigabit.
Pay for the speed you use
Providers sell headline gigabit numbers, but most homes never come close to needing them. What matters is simultaneous demand — the worst-case moment when the TV, the calls, the console, and the smart plugs all want bandwidth at once. Add those up honestly and the right plan is usually far cheaper than the one being upsold.
If the speed checks out but the connection still drags in some rooms, the fix is coverage, not Mbps — size your mesh with the Wi-Fi Coverage & Mesh Node calculator, and see what your connected gear costs to run with Smart-Home Power Cost.
Frequently Asked Questions
How many Mbps do I actually need?
It depends on what runs at the same time, not on the number of people. This tool adds up typical demand — about 25 Mbps per 4K stream, 8 for HD, 5 per video call, 10 per online gamer, and a couple of Mbps for each connected smart device — then adds headroom. A household with a 4K stream, a couple of HD streams, a video call, and a shelf of smart gadgets lands around 100 Mbps, well under the gigabit plans providers push.
Why add headroom instead of buying exactly what I need?
Because real traffic is bursty. Streams buffer ahead, software updates land without asking, and background sync fires when you least expect it, so a plan sized to the bare peak feels slow the moment anything extra happens. The roughly 20% margin here keeps everyday use smooth without paying for a tier you'll never saturate.
Does upload speed matter too?
Increasingly, yes. Video calls, cloud backup, security-camera uploads, and posting large files all lean on upload, which is often far slower than download on cable and DSL plans. This calculator sizes the download side; if your home does a lot of calling or backing up, favour a plan — often fibre — with generous upload, not just a big download headline.
Will a faster plan fix a slow connection?
Not always. Beyond a point, buffering and lag come from Wi-Fi coverage, an aging router, or congestion on your own network rather than the plan itself. If speeds are fine near the router but poor across the house, more Mbps won't help — better coverage will. Check that first with the Wi-Fi coverage tool before paying for a bigger tier.
A planning guide, not a guaranteed throughput. Per-stream numbers are typical steady-state rates; bursts, uploads, and provider overhead vary — size up if in doubt.
