Cost Per Support Ticket: Benchmarks + ROI Calculator (2026)
If you don't know your cost per ticket, you can't measure whether automation pays. Here are the 2026 benchmarks and the four numbers that matter.

The Real Formula
Cost per ticket = (Total support spend per period) / (Total tickets resolved in period)
"Total support spend" must include:
- Agent salaries (loaded — 1.3× base for benefits, equipment, etc.)
- Manager + lead salaries (allocated)
- Tooling cost (helpdesk, AI, analytics)
- Phone/SMS/WhatsApp BSP fees
- Office overhead (allocated by headcount)
- Training cost (allocated)
A common mistake: counting only the helpdesk subscription. That misses 80%+ of true cost.
2026 Benchmarks by Industry
| Industry | Average cost per ticket (INR) | Range |
|---|---|---|
| SaaS (B2B) | ₹420 | ₹250 – ₹800 |
| E-commerce | ₹85 | ₹50 – ₹180 |
| BFSI | ₹650 | ₹400 – ₹1,200 |
| EdTech | ₹140 | ₹80 – ₹250 |
| HealthTech | ₹520 | ₹300 – ₹900 |
| Travel & Hospitality | ₹210 | ₹120 – ₹400 |

Cost Variance by Channel
| Channel | Relative cost vs email |
|---|---|
| Self-service / FAQ | 0.05× |
| AI deflection | 0.10× |
| Chat | 1.0× |
| 1.0× (baseline) | |
| 0.85× | |
| Phone | 4.5× |
| In-person / field | 8.0× |
Phone is expensive because: synchronous, no parallelism, longer average handle time. WhatsApp is cheaper than email because it's asynchronous and templated.
ROI Math for AI Deflection
Imagine you handle 10,000 tickets/month at ₹150/ticket = ₹15 lakh/month support cost.
AI deflection at 30% (modest target):
- 3,000 tickets deflected at AI cost ₹15/ticket = ₹45,000 AI cost
- 7,000 tickets at human cost ₹150 = ₹10.5 lakh human cost
- New total: ₹10.95 lakh/month
- Savings: ₹4.05 lakh/month
At 50% deflection (achievable for FAQ-heavy verticals):
- Savings: ₹6.75 lakh/month = ₹81 lakh/year
Even after platform cost (₹20K–₹50K/month), the ROI is typically 8–15× within 90 days.
Calculate Your Own
- Take your monthly support payroll (loaded).
- Divide by tickets resolved/month → cost per ticket.
- Estimate your deflection rate (start with 30% if you have no baseline).
- Apply the formula above.
If the math doesn't show a 5×+ return, dig in:
- Is your AI grounded in your actual knowledge base?
- Is deflection measured correctly (deflected vs deferred)?
- Is the cost-per-ticket baseline including all loaded costs?
