Free calculators: what missed calls and manual work cost your practice, firm or shop.

Each one starts from published figures where they exist, and says which numbers are ours. Change any dial to match your business. Nothing you enter is stored, and you can share a result with a link.

The phones

What unanswered calls cost.

The work

What the work costs.

Medical billing

What a billing company costs.

Patients

What no-shows cost.

Invoices

What invoices cost, in and out.

The numbers behind the tools

Statistics pages.

The figures the calculators use, with the sample and publisher for each, on the blog.

How these tools are built.

  • One model sits behind each group of tools. The three missed-call pages run the same phone model with different defaults.
  • Each default comes from a measured study, a survey or a government statistic. Where none exists, we use a round number from our own engagements, set on the low side, and label it as ours.
  • Vendor figures are labelled as vendor figures. Most phone statistics online trace back to companies selling answering services.
  • Drag a slider or type a number. Nothing is sent anywhere, and your dials live in the link you copy.

For builders: the controls are DialKit, an open-source tuning panel, and each calculator registers a WebMCP tool, so a browser agent that supports it can run the numbers.

Need a number these don’t cover?

Tell us the workflow. If it’s worth a calculator, we’ll build one. If it’s worth automating, we’ll quote a fixed price, and if the first automation misses the scope we agreed, you don’t pay.
