Test your download speed and latency — then see what speed you actually need
Two different questions hide in "is my internet fast enough?" — what is the line delivering? (measurable) and what does my household need? (smaller than marketed). This tool answers both: a browser-based download-and-latency measurement, and the needs calculator that reveals the industry's open secret — most households pay for 3–10× the bandwidth they can physically use, while their actual complaints (laggy calls, buffering upstairs) are latency and wifi problems no speed tier fixes.
| Activity | Needs (down) | Reality check |
|---|---|---|
| Video call (HD) | 3–5 Mbps | Latency & upload matter more than download |
| HD stream | 5–10 Mbps | |
| 4K stream | ~25 Mbps | Netflix's own number |
| Online gaming | 10–25 Mbps | But latency (<30ms) is the entire experience |
| Big downloads (games, 4K video work) | All you can buy | The one case gigabit genuinely serves |
Stack simultaneous users and a heavy-usage family of four peaks around 100–150 Mbps. Gigabit's real product for most buyers is a bigger number on an unread bill.
If your measured speed comfortably doubles your computed need: the tier below saves $15–30/mo at zero experienced difference — that's $200–350/yr (the Utility tool tracks the win). If you're under-provisioned or the promo expired: competitors' new-customer pricing and your ISP's retention department are the same 20-minute call. And check whether 5G home internet (T-Mobile/Verizon, ~$40–60 flat) now serves your address — its arrival made cable retention departments generous.
Single-server, single-connection browser tests measure a conservative floor; dedicated testers open parallel connections to nearby servers. For plan decisions use the dedicated testers; this tool's value is the needs math and the trend.
Probably nobody: wifi is the bottleneck (distance, walls, band, router age). Test wired or beside the router — if THAT hits plan speed, the fix is router placement or hardware, not the ISP.
Less than feared: video calls want 5 Mbps down/3 up and GOOD latency; even with a streaming household around you, 100 Mbps covers it. Upload and stability matter more than the download headline — cable's weak upload is the WFH pain point fiber fixes.
For big-file professionals (video, game downloads, large backups), multi-4K households, or when it's barely pricier than the tier below (common promo math): sure. As a default: it's the most oversold utility tier in America.
The annual ritual: check competitor new-customer prices (including 5G home internet), call retention, say the competitor's number. 10 minutes, $15-30/mo, repeat yearly when the promo expires. Owning your modem (vs $15/mo rental) stacks on top.
Cable plans hide tiny uploads (10-35 Mbps) behind big download numbers — fine until cloud backups and video calls stack. Fiber's symmetric upload is its quiet superiority; heavy uploaders should weigh it above any download difference.
Yes — the test downloads files from this site and measures locally; nothing about your connection is recorded or transmitted anywhere.
Measure the line, compute the need, fix the wifi before the plan, and make the annual retention call. The internet bill is the rare one where knowing two numbers — yours and needed — is the entire negotiation.
