Why Calculate Chatbot ROI?
Every business investment must have a clear return. A chatbot is no exception. The good news: chatbot ROI is easily measurable and highly favourable.
ROI Calculator: How It Works
1. Calculate your current support costs
Formula: Queries/month × Average time per query × Agent hourly rate
Example:
- 500 queries/month
- Average time: 5 minutes per query
- Hourly rate: £11.50
Current costs: 500 × (5/60) × £11.50 = £479/month
2. Calculate costs with a chatbot
Chatbot resolves 80% of queries (400 queries × £0.02 = £8).
Remaining 100 queries for the agent: 100 × (5/60) × £11.50 = £96.
Costs with chatbot: £8 + £96 = £104/month
3. Calculate savings
- Monthly savings: £479 - £104 = £375
- Annual savings: £4,504
ROI Beyond Cost Savings
Revenue Increase
Chatbots increase conversion rates by 15–30%. With a monthly turnover of £28,750, that means £4,312–£8,625 in additional revenue.
24/7 Availability
How many orders come in outside business hours? On average, 23% of online purchases are made when customer service lines are unavailable.
Reduced Churn Rate
Customers who receive instant answers are more satisfied and buy again.
