Internet providers sell speed like bigger is automatically better. The truth: most homes either overpay for headroom they never touch, or underbuy and blame the router. Here’s the real math.
What each activity actually uses
| Activity | Per stream/device |
|---|---|
| HD streaming (1080p) | ~5 Mbps |
| 4K streaming | ~25 Mbps |
| Video calls | ~4 Mbps |
| Online gaming | ~4 Mbps (but see below) |
| Music/podcasts | ~1 Mbps |
| Browsing & social | ~2 Mbps |
| Cloud backup / big downloads | ~10+ Mbps while running |
Skip the mental math — our speed needs calculator adds up your household’s real peak usage and recommends a plan tier with 30% headroom built in.
Worked examples
- Solo or couple, HD streaming + browsing: peak ~12-15 Mbps → a 25 Mbps plan is genuinely enough.
- Family of four — one 4K stream, one HD, gaming, calls, phones: peak ~45-50 Mbps → 100 Mbps is the comfortable tier.
- Work-from-home + smart home + 4K household: peak ~70-90 Mbps → 150-200 Mbps buys calm evenings.
The gaming truth
Gaming barely uses bandwidth — it’s latency (ping) that decides whether you rubber-band. A wired 25 Mbps connection beats spiky 200 Mbps Wi-Fi for competitive play. If gaming stutters, run an ethernet cable before you upgrade the plan.
When the plan isn’t the problem
If the calculator says your plan should be plenty but everything still crawls, the bottleneck is inside the house — router placement, band selection, or a freeloader device. Work through our 9 Wi-Fi fixes sorted by effort before paying for a bigger number.
Do I need “up to 1 Gbps”?
Almost no household’s simultaneous usage approaches it. Gigabit makes sense for constant huge file transfers or very device-dense homes — otherwise it’s paying for a ceiling you never touch.
Why is my speed test lower than my plan?
Wi-Fi overhead, distance, band, and device limits all shave real-world speed. Test wired next to the router to see what’s truly arriving, then diagnose inward from there.
