Telecom Network Health Score Calculator
Score a mobile network out of 100 from accessibility, retainability, call success rate, latency and congestion KPIs.
Inputs
Network Health Score
91.9/100
Rating
A — Excellent
Accessibility and Retainability Score
39.7/40
Latency Score
23.4/25
Congestion Score
9.0/15
Step by step
Values used
RRC setup success rate = 99.20 %; Call retainability (100 − drop rate) = 99.50 %; Call setup success rate = 98.80 %; Average user-plane latency = 32 ms; Latency target = 30 ms; Cells above the congestion threshold = 4 %
Telecom Network Health Score
score = accessibility/retainability (40) + call setup success (20) + latency ratio (25) + congestion penalty (15), capped at 100.
Network Health Score
= 91.9 /100
Rating
= A — Excellent
Accessibility and Retainability Score
= 39.7 /40
Latency Score
= 23.4 /25
Congestion Score
= 9.0 /15
How it works
Each KPI is normalised onto its own weighted band, so a single bad metric cannot be hidden by four good ones. Latency is scored as a ratio against your target rather than an absolute value, which keeps the score meaningful across very different technologies. Executive reporting wants one number, but the sub-scores are what tell the engineering team whether the problem is coverage, core signalling or plain congestion.
Formula
Telecom Network Health Score
score = accessibility/retainability (40) + call setup success (20) + latency ratio (25) + congestion penalty (15), capped at 100.
- latency ratio
- target latency ÷ measured latency, capped so beating the target does not inflate the score
- congestion penalty
- 1.5 points per percent of congested cells
Frequently Asked Questions
How is Telecom Network Health Score calculated?
score = accessibility/retainability (40) + call setup success (20) + latency ratio (25) + congestion penalty (15), capped at 100. Each KPI is normalised onto its own weighted band, so a single bad metric cannot be hidden by four good ones. Latency is scored as a ratio against your target rather than an absolute value, which keeps the score meaningful across very different technologies.
Why does Telecom Network Health Score matter?
Executive reporting wants one number, but the sub-scores are what tell the engineering team whether the problem is coverage, core signalling or plain congestion.
What values do I need to enter?
This calculator takes 6 inputs: RRC setup success rate, Call retainability (100 − drop rate), Call setup success rate, Average user-plane latency, Latency target, Cells above the congestion threshold. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
