Internet Speed Guide: How Much Do You Actually Need?

Internet plans are sold on speed numbers — 100 Mbps, 500 Mbps, 1 Gig — but most people never connect those numbers to what they actually do online. The result is a lot of households paying for capacity they can't use and others starving on tiers too small for their devices.

What activities actually require

These are real bandwidth requirements, not marketing tier suggestions. They assume the activity is the only thing happening; concurrent activity adds up.

The math for your household

Add up the bandwidth your household uses simultaneously, then add 50% for headroom. A family of four where two parents do video calls (10 Mbps each direction × 2), one kid streams 4K (50 Mbps), one streams HD (10 Mbps), and there's a smart-home baseline (5 Mbps) totals around 90 Mbps download and 25 Mbps upload at peak — entirely covered by a 100 Mbps plan with reasonable headroom, or a 300 Mbps plan with comfortable margin.

That same family using cable internet hits a problem: 25 Mbps upload may exceed the cable plan's upload allocation even if the download speed is plenty. This is why fiber pulls ahead for upload-heavy households (work-from-home, content creation) regardless of total download tier.

Where the marketing tiers actually become useful

100 Mbps: comfortable for households up to 4 people with light-to-moderate use.
300 Mbps: comfortable for most households up to 6 people, including 4K streaming households.
500 Mbps: handles power users — multiple 4K streams, heavy gaming, frequent large file transfers.
1 Gig: not about average use, it's about peak concurrent capacity. Multiple 4K streams + gaming downloads + work calls all at once. Also future-proofing for the next 5+ years.
Multi-Gig (2 Gig, 5 Gig, 10 Gig): currently overkill for almost any residential use case. The case is enthusiast workloads, multiple high-bandwidth users, or NAS/server work where every minute saved on file transfers compounds.

How to actually test your current speed

Speed tests are useful but easy to misuse. Three rules for a meaningful result:

1. Test wired, then wireless. A wired test (Ethernet from router to laptop) tells you what the carrier is delivering. A wireless test tells you what your router is delivering to devices. Big gap between them = router or Wi-Fi issue.
2. Test at multiple times of day. Cable in particular shows congestion at evening peak (7–10 PM). A morning test is meaningless if your problem is evening Netflix buffering.
3. Use multiple test sites. fast.com (Netflix), speedtest.net (Ookla), and your carrier's own test all give slightly different numbers because they test against different servers. The truth is somewhere in the range.

If your speed test consistently shows significantly less than your plan's advertised speed even on a wired connection, that's a carrier issue worth opening a ticket on. If wired matches advertised but wireless doesn't, that's a router or Wi-Fi issue — see our Wi-Fi extension guide.

The over-buying trap

The most common mistake we see is paying for a 1 Gig plan and using a 5-year-old router that delivers 300 Mbps to devices. The household paid for the upgrade and got nothing measurable in return. The conversation we have on these calls is usually about either matching the plan to the gear (downgrade) or matching the gear to the plan (upgrade router, keep plan). Both can be the right move.
