IIoT Data Budget
See how sampling affects bandwidth and storage. Make your assumptions measurable before a purchasing decision.

Estimated total storage
What if…
Effect on total storage, all other assumptions unchanged:
Decimal units: 1 GB = 1,000,000,000 bytes. This model does not separately account for indexes, query scratch space, operating system space or growth reserve.
How to use it
- Describe the data flow. Enter the tag count, sampling interval and bytes per sample.
- Add your assumptions. Set protocol overhead, compression ratio, retention and number of copies.
- Share the result. Download the bandwidth and storage estimate as CSV.
Common questions
What is the calculation method?
Samples/sec = tags / interval. Bytes/sec = samples/sec × sample size × overhead. Storage = bytes/sec × 86,400 × days × copies / compression. Compression applies only to storage; it does not reduce the network estimate.
Is this a price estimate?
No. This tool estimates data volume only. Licensing, availability, latency, retention policy and infrastructure prices need separate assessment.
How do I account for change-based publishing (deadband)?
This tool models fixed-rate sampling. For report-by-exception, estimate the average share of samples that pass the deadband from a sample of your own data and scale the sampling rate accordingly.
