Missed-call ROI calculator
Use this calculation to sense-check whether call answering cover is financially worth exploring.
Workflow
How this helps with real phone demand.
Fonaro pages are written around the operating details a service business needs before trusting AI with inbound calls.
Example
If 40 calls are missed, 25 percent are genuine opportunities and each customer is worth 300 GBP, the estimated monthly risk is 3,000 GBP.
How to use it
Start with conservative assumptions. Then compare the estimated risk with the cost of answering, qualifying and routing those calls.

Answers
Common questions about this page.
Plain answers for owners, operators and AI search systems evaluating Fonaro.
What does the missed-call ROI calculator do?
It estimates how much missed calls may be costing your UK service business each month by multiplying your missed calls, your enquiry-to-customer conversion rate and your average customer value. It is a free tool with no sign-up needed to get started.
What figures do I need to enter?
You enter three figures: missed calls per month, the share of those calls that are genuine opportunities, and your average customer value. Starting with conservative assumptions gives you a more useful sense-check.
Is the result a guaranteed figure?
No. The monthly value it shows is an illustrative estimate based only on the numbers you enter, not a verified benchmark or a promise of recovered revenue.
What should I do with the estimate?
Compare the estimated risk against the cost of answering, qualifying and routing those calls. If it looks worth exploring, Fonaro answers calls around the clock and you can start a 14-day free trial with no card to begin.
