Telecom Network Health Score Calculator
Score a mobile network out of 100 from accessibility, retainability, call success rate, latency and congestion KPIs.
About Telecom Network Health Score Calculator
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
Worked example
With the default values below, Telecom Network Health Score Calculator returns Network Health Score of 91.9. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 6 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
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.
