Roll availability, performance, capacity, security and operations metrics into one weighted network health score.
Availability is scored only across the 99–100% range because that is where operational networks actually differ, and capacity is scored on headroom below an 85% ceiling rather than raw utilisation. Comparing each component against its own maximum identifies the weakest area, which is not necessarily the one with the fewest points. One composite number is what gets reported upward, but the weakest-area output is what stops that number from hiding a single dimension that is quietly failing.
Overall Network Health Score
health = availability (30) + performance (25) + capacity headroom (20) + patch currency (15) + operational load (10).

This calculator takes 7 inputs: Availability achieved, Average latency, Latency target, Packet loss, Peak link utilisation, Devices fully patched, Network incidents per month. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
