Orders, bookings or billable hours that don’t come back later.
100% means nobody can do anything; 50% means half their work.

What causes downtime

The Outages Small Businesses Actually Have

Most downtime isn’t a dramatic hack. It’s ordinary things nobody was watching, and most of them can be prevented or shortened.

Internet outage

One internet line and no backup. A second connection with automatic failover keeps phones, email and cloud apps running.

Failed server or hard drive

Old hardware fails without warning. Monitoring spots failing drives early, and a tested backup shortens the outage. See how to test your backups.

A bad update

An update breaks a key app on every PC at once. Staged patching tests updates on a few machines first.

Ransomware

Files encrypted and systems locked, often for days. Immutable backups and a plan make the difference. Read what to do in a ransomware attack.

Hacked email account

A compromised mailbox can mean days of cleanup, warning clients and checking payments.

One critical PC

The reception or accounting PC dies, and so does billing. Spare hardware and good documentation get you back fast.

Why the number matters

Use It to Decide What’s Worth Fixing First

If an hour of downtime costs more than a year of a backup internet line, the decision makes itself. The same goes for monitoring, a newer server or tested backups.

Share the result with your partners or your bookkeeper. It turns “IT is an expense” into a number everyone can weigh against the risk.

Frequently asked questions

Downtime Calculator FAQs

About the numbers and what to do with them.

How do you calculate the cost of IT downtime?

Two parts: the wages you pay while people can’t work (staff × hourly cost × how much work stops), plus the sales that are lost for good (your revenue per open hour × the share that doesn’t come back). This calculator adds the two for an hour, a workday and a week.

What should I put for hourly cost per person?

Wage plus benefits and payroll costs. If you don’t know, use the average hourly wage and add about a fifth. It doesn’t need to be exact to be useful.

Why isn’t all of our revenue counted as lost?

Many sales aren’t lost, just delayed: clients call back or rebook. Set the “lost for good” percentage to match your business. A walk-in shop loses more than a firm with booked appointments.

What isn’t included?

Overtime to catch up, recovery and repair costs, missed deadlines and penalties, data you can’t get back, and clients who leave. So the real cost is usually higher than this estimate.

How can a small business reduce downtime?

Monitoring that catches problems early, tested backups, a second internet line, staged updates and a written recovery plan. Our managed IT service includes the monitoring and patching.

Is my data stored?

No. The calculator runs in your browser. If you share the link, the numbers are in the link itself, so only share it with people you’d tell anyway.
