How the calculation works
We estimate missed calls per month by multiplying your total call volume by your missed-call percentage. We then apply your conversion rate to estimate how many of those missed calls would have become paying customers. Lost revenue is calculated as potential customers × average job value, then projected over 12 months for the annual figure.
This is a directional estimate — real outcomes vary by industry, time of day, follow-up speed, and caller intent. The calculator uses conservative defaults to avoid overstating the case.
| Assumption | Default | Notes |
|---|---|---|
| Conversion rate | 30% | Adjustable — typical for inbound service enquiries |
| Average job value | £500 | First job value only, not lifetime customer value |
| Missed call rate | 25% | Includes out-of-hours, engaged, and unanswered |
| Repeat customers | Not included | Real loss is typically significantly higher |
Frequently Asked Questions
It is common for UK small businesses to miss between 20–40% of inbound calls, with the figure rising to 60%+ for sole traders and trades businesses during busy periods or outside business hours.
A 20–35% conversion rate is typical for inbound phone enquiries in service businesses. If your business has a strong reputation or a niche offering, this can be higher. Adjust the slider to reflect your actual close rate.
No. The calculator estimates lost revenue from first-time enquiries only, using your average job value. When you factor in lifetime customer value, the real loss figure is typically significantly higher.
Even if only 10–15% of missed callers convert, at typical UK job values the annual loss is still significant. Set a low conversion rate in the slider to model a conservative scenario for your business.
