Upload speed calculator
Upload is the half of your plan that usually runs out first. Add your live stream, video calls, cameras and backups to see how much upload you need and which plan speeds cover it.
| Plan upload | Enough? | Time to upload 10 GB |
|---|
Times assume 90% of the plan's upload is usable.

How it’s calculated
Every item sends a steady stream of data. The calculator adds them up and applies headroom:
upload needed = (stream bitrate + calls × per-call upload
+ cameras × 2 + devices × 0.05 + backup) × (1 + headroom) - Live streaming: your encoder bitrate is your upload use. Twitch recommends up to 6,000 kbps (6 Mbps) for 1080p at 60 fps. Stream settings are often given in kbps; the kbps to Mbps converter turns them into plan units.
- Video calls: Zoom publishes 1.8 Mbps up for a 720p group call and 3.0 Mbps up for 1080p.
- Cloud cameras: 2 Mbps each while recording. This is our estimate; check your camera maker's figure.
- Other devices: 0.05 Mbps each, our estimate for phones, speakers and background sync.
- Backup target:
Mbps = GB × 8,000 ÷ seconds. Backing up 50 GB in an 8-hour overnight window needs about 13.9 Mbps on its own.
The result table checks common plan uploads (10, 20, 35, 50, 100, 300 and 1000 Mbps) against your total and shows how long your upload would take on each, assuming 90% of the plan's upload is usable.
Worked example: a 1080p60 streamer
| Item | Upload (Mbps) |
|---|---|
| 1080p60 stream (Twitch 6,000 kbps) | 6.0 |
| 1 × 720p video call (Zoom) | 1.8 |
| 8 other devices | 0.4 |
| Peak | 8.2 |
| With 30% headroom | 10.7 |
A plan with 20 Mbps upload is comfortable here; 10 Mbps is not. A 10 GB video upload on that 20 Mbps plan takes about 1 h 14 min at 90% usable. Run large backups when you're not streaming, or cap their speed in the backup app. For one-off uploads of any size, the upload time calculator gives the time directly.
Why upload matters more than it looks
Many cable plans sell hundreds of Mbps of download with a small fraction of that for upload, while fiber plans are often symmetrical. A streamer at 6 Mbps, plus someone on a 1080p call at 3 Mbps, plus two cameras at 4 Mbps already needs 13 Mbps, or about 16.9 Mbps with 30% headroom. On a plan with 10 Mbps upload, the stream drops frames no matter how fast the download is.
When upload runs out, latency also rises for everyone in the house, because the router queues outgoing packets. Game lag and choppy calls during a backup are the typical symptom; latency vs bandwidth explains why, and upload vs download speed covers how plans split the two.
Choosing headroom
The default of 30% covers normal variation in call and stream bitrates. Live streams need a steady upload, and streamers commonly keep 30–40% spare, so move the slider up if streaming is the priority. If you only make the odd call, the default is plenty. For the download side of the same household, use the internet speed calculator.
Frequently asked questions
What upload speed do I need for Twitch?
Your upload must carry your stream bitrate plus some spare. Twitch recommends up to 6,000 kbps for 1080p60, so plan for at least 8 Mbps of upload for the stream alone, and more if others in the house are on calls at the same time.
Is 10 Mbps upload enough?
For one or two video calls and ordinary use, yes. It is tight for 1080p live streaming together with anything else, and slow for large backups: 50 GB takes about 12 hours and 21 minutes at 90% of 10 Mbps.
Is 20 Mbps upload good?
It covers most households, including a 1080p stream or several video calls at once. It matches the upload part of the FCC's 2024 broadband benchmark of 100 Mbps down and 20 Mbps up.
