Missed calls
This estimate looks at business-hours calls that never make it back into the scheduling flow because they go unanswered or to voicemail.

A quick diagnostic for dentist owners and practice managers. Adjust a few inputs and get an estimated annual range for what missed calls, after-hours gaps, and lost appointments may be costing the practice.

Estimated annual leakage
$75,000
midpoint estimate
Your practice may be losing $40,000 to $115K each year based on your inputs and benchmark assumptions.
Midpoint per month
$6,000
Estimated lost visits / year
300
That is roughly equivalent to 30 hygiene visits or 15 new patient appointments going unrecovered each month (approximate).

$30,000 to $67,500
After-hours calls
Patients who call when the office is closed and are not fully captured by current coverage.

If you recovered just 30%
That would mean roughly $22,500 back in annual production — without adding staff or increasing marketing spend.
Biggest opportunity
This type of leakage is exactly what Kline’s Front Desk workflow handles automatically — answering incoming calls, following up on missed callers, and managing after-hours scheduling so nothing falls through the cracks.

What the estimate includes
Three categories of leakage. One cleaner view of where the schedule is slipping.
The point is not to produce false precision. It is to show which operational leaks are likely large enough to deserve attention.
After-hours calls
After-hours calls are estimated separately from daytime missed calls so the same calls are not counted twice. Coverage quality changes how much of that leakage remains.
No-shows / cancellations
Lost appointments consume capacity even when the slot had revenue potential. This category estimates how much of that production is not recovered elsewhere in the week.
Why it compounds
Small weekly misses turn into a meaningful annual drag.
Revenue leakage is usually operational, not dramatic. The pattern matters because it repeats every week.
Owners feel it in production
A few leaks each week compound into a meaningful annual number. The issue is rarely one catastrophic failure. It is repeated small losses.
Managers feel it in the workflow
Voicemails, callbacks, manual rescheduling, and open slots create operational drag. Leakage is a staffing and process problem as much as a revenue problem.
Recovery matters more than awareness
Knowing leakage exists is not enough. The practical question is which category is largest, and whether the current workflow can close it consistently.
FAQ
A few notes on how to read the estimate.
What does this calculator estimate?
It estimates annual revenue and capacity leakage from missed daytime calls, after-hours calls that are not fully covered, and lost appointments that do not turn back into productive chair time.
How does the calculator avoid double-counting after-hours leakage?
Missed daytime calls and after-hours calls are modeled as separate pools. After-hours leakage is not added on top of the same calls already counted inside missed-call leakage.
Are these exact numbers?
No. This is a directional estimate based on your inputs and benchmark assumptions, designed to help a practice understand where operational leakage may be concentrated.
What to do with the number
If the leakage is meaningful, the next question is whether the workflow can recover it consistently.
Kline handles incoming calls, follows up on missed callers, fills schedule gaps, and runs recall automatically — so more of the schedule gets recovered instead of waiting on staff bandwidth.
