The cost of an hour of downtime
Chairs, payroll, lab cases, reviews — not a mystery novel.

Short answer: The cost of an hour of dental downtime is lost production plus idle payroll plus recovery costs plus a reputation cost that is hard to measure but real. Calculate it with your own numbers: production per hour across affected operatories, loaded staff cost, overtime and reschedule leakage. Use it to set your RTO and judge what response time is worth.

What does an hour of downtime cost a dental practice?
More than most owners assume, because the cost is spread across several ledgers that are rarely added together. A practical way to see it is to build it up from components.
What are the components?
- Lost production. Procedures that cannot be performed, or are performed less profitably, while systems are down.
- Idle payroll. Clinicians and staff are paid whether or not they can work.
- Recovery cost. Overtime, catching up after the outage, IT emergency charges.
- Schedule leakage. Patients who reschedule, do not return or book elsewhere.
- Lab and supply costs. Cases that must be redone, remakes, expedited shipping.
- Reputation. Reviews, referrals and trust, which are slow to measure and slow to repair.
- Compliance cost, if the downtime involves a security incident. See Florida data-breach notification for dental practices.
How do you calculate it?
Cost per hour ≈ (production per hour × share lost) + (loaded staff cost per hour × people idle) + (recovery cost) + (estimated leakage)
What does it look like with example numbers?
Illustrative only. Replace with your own figures.
| Input | Example |
|---|---|
| Operatories affected | 4 |
| Production per operatory-hour | $400 |
| Share of production lost during outage | 70% |
| Staff idle | 8 people × $28/hour loaded cost |
| Recovery overtime and emergency costs | $300 |
| Schedule leakage (reschedules, no-returns) | $400 |
| Component | Calculation | Amount |
|---|---|---|
| Lost production | 4 × $400 × 70% | $1,120 |
| Idle payroll | 8 × $28 | $224 |
| Recovery | $300 | |
| Leakage | $400 | |
| Total for one hour | about $2,044 |
A half-day outage in this example approaches $8,000 before any reputational cost. Your numbers will differ; the discipline of computing them is the point.
What can you do with the number?
- Set your RTO. If an hour costs this much, how long can you really be down? See Cloud backup that is actually HIPAA-shaped.
- Value response commitments. A faster P1 response is worth some fraction of the hours it saves. See What a 15-minute P1 SLA actually means.
- Compare IT options on total cost, not just invoices. See Break-fix vs managed vs autonomous.
- Decide where prevention is worth it: redundant internet, spare sensor PCs, UPS, tested backups.
How does this relate to the monthly price of IT?
Compare the plan price per location to the cost of a few hours of downtime avoided. CyberDental's plans are Remote $350, Priority $650 and Ultimate $1,200 per location per month. Whether that is worth it depends on your own outage cost and risk, which is why the calculation is yours to run. See Why dental IT is priced per location.
What is hard to price?
The patient who left in pain because the x-ray would not take, and never came back. That is why downtime in dentistry is a clinical matter, not just an operational one. See Dental IT is a clinical issue.
Frequently asked questions
How do I calculate downtime cost for my dental practice?
Add lost production, idle payroll, recovery costs and estimated schedule leakage for the hours affected, using your own production and staffing numbers.
What is a good recovery time objective for a dental practice?
It depends on your cost per hour of downtime and tolerance. Calculate your hourly cost first, then set an RTO and design backup and support to meet it.
Is the example cost in this article typical?
No. The figures are illustrative to show the method. Use your own numbers.
