Network Utilization Calculator

Calculate link utilization, available bandwidth, and time to saturation at a given growth rate.

The maximum rated speed of the network link. This is the physical interface speed (e.g., 100 Mbps, 1 Gbps, 10 Gbps).
The actual measured throughput on the link. This is the average data rate observed during the measurement period.
The highest throughput observed during the measurement period. Used to calculate peak-to-average ratio and burstiness.
Mbps
Expected monthly increase in traffic. Used to estimate when the link will reach capacity. Typical enterprise growth is 2-5% per month.
