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:

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

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.
