Calculate the financial return from a customer service chatbot. Enter your current query volume, agent costs and deflection rate to see annual savings, ROI and payback period.
Customer service chatbots are one of the highest-ROI AI investments for businesses with significant inquiry volume. A chatbot deflecting 45% of 2,000 monthly queries — at a cost of £32,000/year per agent handling 500 queries/month — saves approximately £14,400/year in agent cost for a £300/month platform cost. That is a 300%+ ROI before the payback calculation.
| Industry | Typical Deflection Rate | Query Types Handled |
|---|---|---|
| E-commerce | 40–65% | Order status, returns, FAQs |
| Banking / Financial | 30–50% | Balance enquiries, branch hours, basic FAQs |
| SaaS / Tech Support | 35–60% | How-to queries, known issue tracking, account management |
| Telecoms / Utilities | 45–70% | Bill enquiries, service status, upgrades |
| Healthcare (admin) | 25–45% | Appointment booking, hours, general information |
Deflection rate = percentage of queries fully resolved by the chatbot without human agent involvement. 35-50% is typical for well-implemented chatbots. 50-70% is excellent. Below 25% suggests the chatbot is not handling enough of the common query types. Deflection rate is highly dependent on the quality of training data, the breadth of queries the chatbot is designed to handle, and the complexity of your product/service.
Chatbot costs range widely: basic FAQ chatbots (Tidio, Intercom, Freshchat) £30-200/month; mid-range conversational AI chatbots £200-800/month; enterprise AI-powered chatbots £1,000-10,000+/month. Implementation costs: basic setup £500-2,000; custom integration and training £5,000-50,000+. The ROI model must include implementation amortised over the expected useful life (typically 2-3 years).
