Telecom Dropped Call Rate Percentage

A voice quality / accessibility KPI. Distinct from network availability (uptime) and from SaaS churn.

Drop rate % = dropped ÷ attempts × 100.

Tip: Keep “Dropped Calls” and “Call Attempts” on the same basis (units, period, and definition) before you calculate.

The Formula

Telecom Dropped Call Rate Percentage
Dropped call rate % = (Dropped calls ÷ Call attempts) × 100

Worked Example

Scenario: Dropped calls 850; call attempts 100,000.
Step 1: 850 ÷ 100000 = 0.0085
Step 2: × 100 = 0.85%
Answer: Dropped call rate is 0.85%.
