In this guide
Core Support Metrics
First Response Time (FRT)
Time from customer contact to first agent response. Lower is better. Benchmark by channel:
- Live Chat: Under 1 minute
- WhatsApp: Under 5 minutes
- Email: Under 4 hours
Average Resolution Time (ART)
Time from first contact to issue resolved. Varies by complexity. Track by issue type for meaningful benchmarks.
First Contact Resolution (FCR)
Percentage resolved in first interaction. Higher is better. Target: 70%+. Low FCR means customers contact multiple times for same issue.
Ticket Volume
Total conversations per period. Track trends. Sudden spikes might indicate product issues. Gradual growth needs capacity planning.
Customer Satisfaction Metrics
CSAT (Customer Satisfaction Score)
Post-interaction survey. "How satisfied were you?" Scale of 1-5 or 1-10. Target: 4.5/5 or 85%+ positive.
NPS (Net Promoter Score)
"How likely to recommend?" -100 to +100 scale. Good for overall relationship health. Target: 30+ is good, 50+ is excellent.
CES (Customer Effort Score)
"How easy was it to resolve?" Lower effort = better experience. Often more predictive of loyalty than CSAT.
Operational Efficiency Metrics
Agent Utilization
Percentage of time agents spend in conversations. 70-80% is healthy. Below 60% = overstaffed. Above 85% = burnout risk.
Cost per Ticket
Total support cost divided by ticket volume. Include: salaries, tools, management, overhead. Track trend over time.
Automation Rate
Percentage of queries handled without human agent. Higher = more efficient. 60-80% is achievable with good AI.
Backlog/Queue Size
Unresolved tickets at any point. Should trend toward zero. Large backlog indicates capacity issues.
Quality Metrics
Quality Assurance Score
Internal review of agent responses. Score based on rubric: accuracy, tone, resolution. Regular calibration is essential.
Escalation Rate
Percentage escalated to higher tier. High rate might mean training gaps or unclear processes.
Reopen Rate
Tickets reopened after marked resolved. High rate = premature closure or incomplete resolution.
