How We Calculate Your Revenue Loss
Our calculation is based on scientific studies and industry-specific data from the German market.
The Formula
Revenue loss is calculated using the following formula:
Missed Calls × New Customer Rate × Order Value × Close Rate × 52
The new customer rate filters out support calls and existing customers – only real new customer inquiries are counted. Rates vary from 12% (medical practices) to 35% (trades/auto) based on industry research.
62% missed
On average, 62% of all calls to small businesses go unanswered.

Why Missed Calls Are So Expensive
Immediate Customer Loss
When a customer can't reach you, they call the next provider. Google shows at least 3 alternatives.
Lost Emergency Jobs
Emergencies (burst pipes, toothaches, car breakdowns) have the highest margins – but only if you're immediately available.
Negative Reviews
Frustrated customers leave bad Google reviews. 'Never reachable' is one of the most common complaints.
Missed Repeat Customers
A lost new customer means not just one order, but potentially decades of follow-up orders and referrals.
Hidden Costs
Callbacks cost time, customers forget details, and employees get interrupted at work.
Competitive Disadvantage
Competitors with 24/7 availability automatically win the customers you can't reach.
Frequently Asked Questions
What about support calls and existing customers?
The calculator accounts for the fact that not every call is a potential new customer. Depending on the industry, only 12-35% of calls are actual new customer inquiries – support, follow-ups, and existing customers are already filtered out. These values are based on studies by Ruby.com and Martech Health.
Where does the industry data come from?
Our data is based on market analyses, industry associations, and anonymized customer data from German SMEs. Values are regularly updated to reflect current market conditions.
Is the calculation really realistic?
Yes, we use conservative, research-based values. Only 12-35% of calls are counted as new customer inquiries – this matches industry studies. Additional losses from negative reviews, lost referrals, and customer lifetime value are not included.
Why do close rates vary so much?
Close rates depend on the industry. Physiotherapists have high rates (70%) because patients need specific appointments. Real estate agents have lower rates (15%) since prospects often contact multiple agents.
How can I measure my actual loss?
Keep a tally of all missed calls for one week. Note how many were new customer inquiries. Multiply these by your average order value and estimated close rate.
What does ROI mean in this context?
ROI (Return on Investment) shows how much you get back for every euro invested. An ROI of 500% means that for every euro of Vokaro costs, you secure 5 euros in revenue.
Does the calculator also consider emergency calls?
The calculation uses average values. Emergency calls (e.g., burst pipes, acute pain) typically have higher order values and close rates – your actual loss could therefore be higher.
