Common questions
How accurate is the missed call calculator?
It uses the same formula UK-wide automation agencies use to baseline lost revenue: missed calls per week multiplied by your close rate multiplied by your average job value, then annualised. It's an honest estimate, not a guess — but it can't account for callers who try again later or get referred.
Why does the calculator use 40% as a default close rate?
40% is the industry-standard baseline used across UK trade automation calculators. Most sole trader plumbers actually sit between 30% and 50% on inbound leads they speak to directly — adjust the slider to match what feels true for you.
What counts as a missed call?
Anything that hits your voicemail, gets ignored because you're on the tools, or rings out because your phone was on Do Not Disturb. If they didn't speak to you and you didn't call back within the hour, count it as missed.
Is this calculator only for plumbers?
The maths works for any trade, but the benchmarks and personalised commentary are tuned for UK sole trader plumbers. If you're an electrician, gas engineer, or other trade, the headline number is still reliable.
