When to use this calculator
Compare measured traffic with an entered nominal link capacity. Use compatible measurement layers and intervals; overhead can change the practical capacity.

PUTTING IT INTO PRACTICE
Network Utilisation: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Measured average throughput (Mbps) | 60 |
| Nominal capacity (Mbps) | 100 |
| Result | 60 % |
- Check the input labels and enter the example values above.
- Apply the relationship: Utilisation (%) = measured throughput/capacity × 100.
- The result is 60 %, rounded for display.
How to interpret your result
Use compatible measurement layers and intervals; overhead can change the practical capacity.
Bits and bytes differ by eight. Average request rate can hide peaks and concurrency. A packet’s serialization delay is only one part of end-to-end network latency.
Frequently asked questions
Does serialization delay equal network latency?
No. Propagation, queuing, processing, framing and other paths can add to total latency.
When is the network utilisation calculator useful?
Compare measured traffic with an entered nominal link capacity. Use compatible measurement layers and intervals; overhead can change the practical capacity.
How do I use the network utilisation calculator?
Enter measured average throughput (mbps), nominal capacity (mbps). The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Utilisation (%) = measured throughput/capacity × 100.
What should I check before using the result?
Use compatible measurement layers and intervals; overhead can change the practical capacity.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
