What does IT downtime really cost a small business?
Downtime costs more than most owners think, because the bill shows up in several places at once. When the internet drops or a key system fails, you keep paying staff who can't do their jobs, you lose some revenue you won't get back, and someone has to stay late to catch up. This calculator puts those pieces together so you have a real number to plan around instead of a guess.
For a medical or dental practice, the picture is very concrete. The front desk can't check patients in. Providers can't see charts, X-rays or medication lists. Claims don't go out. Patients sit in the waiting room, and some of them leave. For an accounting firm or other office, it's billable hours that disappear and deadlines that slip.
How the calculator works
The tool adds up four kinds of cost. Each one is simple on its own:
| Cost | What it means | How it's calculated |
|---|---|---|
| Paid time lost | Wages and benefits you pay while people can't work | Staff affected × hourly cost × % of work that stops |
| Lost revenue | Sales, visits or billable time that won't be made up later | Revenue per hour × % you won't recover |
| Catch-up overtime | Re-entering data, calling patients back, clearing the backlog | Overtime hours × hourly cost × 1.5 |
| Other costs | Emergency IT call-outs, rush parts, goodwill gestures | The amount you enter, per incident |
The cost per hour combines paid time and lost revenue. The cost per incident multiplies that by how long a typical outage lasts and adds the catch-up costs. The cost per year multiplies by how many incidents you have. The bar chart shows which part of the cost is biggest, which tells you where to focus.
Tips for getting realistic numbers
- Use the fully loaded hourly cost. Wages alone understate the real number. Include payroll taxes and benefits.
- Be honest about how much work stops. If staff can keep working on paper for an hour, 50% may be right. If your scheduling, charting and phones all run through the internet, it's closer to 100%.
- Count the small outages. A half-day lost to a broken printer driver or a slow server counts. Ask your team; they usually remember better than the owner does.
- Think about your worst day, not just a normal one. Run the numbers a second time with a full-day outage. That's what a failed server or a ransomware attack can look like, and recovery from those often takes longer than a day.
How to use your results
Your yearly downtime cost is the budget you can justify spending to prevent it. If downtime costs you a meaningful amount each year, then a backup internet line, better backups or proactive maintenance that cuts that number in half pays for itself. A few practical ways to use the result:
- Compare it with prevention costs. A second internet connection with automatic failover is usually a modest monthly cost. Our dental practice case study shows how cellular failover kept an office running when its main internet line died.
- Set your recovery targets. The cost per hour helps you decide how quickly each system must be back. That's called your recovery time objective (RTO). Our backup and disaster recovery guide explains how to set it.
- Plan for the outage you can't prevent. Practices should have a written downtime procedure: how to check patients in, what to print each morning, who to call. See our EHR downtime and internet failover plan.
- Include it when comparing IT support options. The cheapest IT support isn't cheap if it leaves you down for a day. Our managed IT services cost guide and in-house vs managed IT calculator can help.
The most common causes of downtime in small offices
Most outages we see in small offices and practices come from a short list of causes:
- Internet outages. A single internet line is a single point of failure, especially for cloud-based practice software and internet phones.
- Aging hardware. Computers, servers and network gear that are past their useful life fail more often. The computer replacement planner helps you spot them.
- Ransomware and other attacks. These are the most expensive kind of downtime because recovery takes days, not hours. Read our ransomware protection guide.
- Updates gone wrong. Unmanaged updates can break software at the worst time. Managed, tested patching avoids most of these surprises.
- Severe weather. In Florida, hurricanes and power cuts are a real planning issue. See our hurricane preparedness guide for IT.
What this calculator doesn't include
To keep things honest, the calculator only counts costs you can reasonably estimate. It leaves out data that's lost for good, the cost of a reportable data breach, regulatory penalties, staff turnover from constant frustration, and patients or clients who quietly don't come back. Those can be large, but they're hard to put a number on, so treat your result as a floor, not a ceiling.
