Assumptions
Results update as you type. Example figures are illustrative.
Your working data
Edit cells directly or import a CSV. Download “Input CSV” for the required column names. Up to 200 rows; scroll the table sideways for additional fields.
Detailed analysis
Exports include all results, regardless of the search filter. The HTML report includes assumptions and source data; use your browser’s Print command for PDF.
Chart shows the first 20 rows; negative values use a warm color. Click table headers to sort.
Compare up to four scenarios
Capture the current inputs, change assumptions and capture again. Scenarios are included in downloaded projects.
What this model includes
Manual traffic estimates, not a speed test. Simultaneity is an average assumption; latency, Wi-Fi airtime and provider contention are not simulated.
Import and save safely
CSV imports use your current assumptions. Project files restore assumptions, rows and saved scenarios. No automatic saving: download a project before closing this page. Imports are limited to 10 MiB and 200 rows. Calculations run in your browser; the site’s advertising and analytics follow its privacy policy.
Using Home Network Bandwidth Planner
Combine device groups, simultaneous activity and upload/download requirements to estimate a household bandwidth budget.
- Enter your download and upload speeds and the headroom to keep.
- List each activity with devices, share in use at once and speed per device.
- See both gauges beside your table, then download the budget.
Example
The worked example includes Video streaming, Video calls, Cloud backup, Gaming. Change the first reserved headroom (%) setting and compare the result with a saved baseline.
Questions & answers
What does Home Network Bandwidth Planner calculate?
Combine device groups, simultaneous activity and upload/download requirements to estimate a household bandwidth budget.
What are the important limitations?
Manual traffic estimates, not a speed test. Simultaneity is an average assumption; latency, Wi-Fi airtime and provider contention are not simulated.
Can I continue my work later?
Yes. Save a project JSON file and reopen it with Import CSV / project. It contains the working data, assumptions and up to four scenarios. Nothing is saved automatically.
What CSV columns do I need?
activity, devices, simultaneous, down, up. Download Input CSV for a compatible example. CSV imports keep your current assumptions.
Are these example figures current industry benchmarks?
No. They are illustrative values to demonstrate the model. Replace them with figures appropriate to your situation.
