Where do the industry defaults come from?

Our own pipeline database (~2,000 analysed SMBs in DE/ES) combined with public benchmarks (Invoca 2024, BVSK 2024, ZDH 2024). The defaults are deliberately conservative — reality is worse in many businesses.

What happens to my inputs?

Nothing. The calculator runs fully in the browser. No submit, no database, no email capture. Close the page and the values are gone.

Is the result accurate?

No — it's an estimate. The two biggest error sources are average deal value and conversion rate. Replace both with real numbers from your books and the result becomes reliable. For a proper audit, book 30 minutes with us and we will look at your actual call data.

What can I actually do about missed calls?

Three options: (1) A call centre — expensive, often poorly trained, off-brand. (2) A part-time receptionist — ~€1,800/month net, opening hours only. (3) An AI phone assistant — 24/7, books into your calendar, ~€150–400/month depending on volume. We implement option 3. Only when it actually pays back.

Does this apply to B2B businesses too?

Yes, even more so. A trades business losing a €2–5k job because the owner is on-site loses more in a week than an AI assistant costs in a year.

Missed Call Revenue Calculator

How much revenue do you lose every month because nobody picks up?

How the math works

01
Missed calls per day
calls per day × missed rate
02
Lost revenue per missed call
average deal value × call-to-deal conversion
03
Monthly loss
missed calls/day × work days × loss per call
