Assumptions (conservative)
- 60% of tickets auto-resolved by the AI - industry research reports 60-80% (Juniper Research, Gartner). We default to the low end.
- £0.20 average inference cost per auto-resolved ticket (typical 2025-26 LLM pricing + tooling overhead).
- 90% reduction in first-response time on auto-resolved tickets (IBM, 2023).
- Savings = human handling cost minus inference cost on auto-resolved tickets. Implementation, maintenance, and escalated-ticket costs are excluded from this estimate and discussed in a real scoping conversation.

How we calculate AI chatbot ROI
The calculator estimates what your support tickets cost today versus what they would cost with a custom AI chatbot resolving the routine ones. The formula is deliberately conservative: monthly savings = (monthly tickets × 60% auto-resolution) × (your cost per ticket − £0.20 AI inference cost). Industry research puts auto-resolution at 60-80% of routine queries (Juniper Research, Gartner) - we use the low end.
This is a chatbot cost savings calculator - it does not include the build investment. For that side of the equation, use the AI cost estimator or read our guide to custom AI chatbot costs. If you are weighing up whether you need AI at all, start with AI chatbot vs traditional chatbot - or see what a custom AI chatbot build involves.
AI chatbot ROI - common questions
How do you calculate the ROI of an AI chatbot?
We use a conservative formula: monthly savings = (monthly tickets × 60% auto-resolution rate) × (your cost per ticket − £0.20 AI inference cost), annualised over 12 months. Industry research reports 60-80% auto-resolution rates (Juniper Research, Gartner) - we deliberately use the low end so the estimate errs on the side of caution.
What is a typical ROI for an AI chatbot?
Businesses deploying AI chatbots report roughly 30% lower customer service costs (Juniper Research) and 60-80% of routine queries resolved without a human. For companies handling 500+ tickets a month, the typical payback period on a custom build is 2-6 months, after which savings compound as volume grows.
How much does a custom AI chatbot cost to build?
A custom AI chatbot for a UK business typically costs £3,000-£25,000+ to build, plus £200-£1,500 per month in maintenance and inference costs, depending on integrations and complexity. This calculator estimates the savings side; our AI cost estimator and pricing guide cover the investment side.
Does this calculator include build and maintenance costs?
No - it estimates gross savings from auto-resolved tickets only. Implementation, maintenance, and escalated-ticket costs are excluded, because they vary with scope. For a full picture, pair it with our AI cost estimator or book a free demo where we scope real numbers on your actual support data.
