Telegram engagement rate calculator

The single most useful number is the participation rate: weekly active members ÷ total members. It varies enormously with group size — lurker share grows as groups grow — so judge your group against its own size class, and against its own last month.

Bands are drawn from community-management practice and patterns across groups Limzo tracks. They're guidance, not gospel — a niche expert group at 4% can be healthier than a meme group at 20%.

No black box — these are the exact formulas the calculator runs, all from your last 7 days:

• Participation rate = weekly active members ÷ group members × 100 — weight 40%
• Conversation depth = weekly messages ÷ weekly active members — weight 20%
• Reply ratio = replies ÷ weekly messages × 100 — weight 25%
• Reaction rate = reactions ÷ weekly messages × 100 — weight 15%

Each metric is mapped against the benchmark bands above to a 0–100 sub-score, and the health score is the weighted average. Leave an optional field empty and its metric is skipped, with the weights rebalanced across the rest — the score never pretends to know something you didn't tell it.

One thing this calculator can't see: who is doing the talking. A group where five members produce 90% of messages scores the same as one with broad participation. Limzo's weekly report and public stats page break activity down per member, so concentration like that shows up immediately.
