How Much Is Downtime Costing Your Business? |
When most business owners think about downtime, they picture something dramatic. A ransomware attack. A flood. A catastrophic hardware failure.
But most downtime doesn’t announce itself. It arrives unexpected and often disguised as a minor inconvenience:
An automatic update reboots a critical machine at the wrong time. An SSL certificate expires, and your website goes offline. A software subscription lapses because it was billed to an expired card. Your internet provider scheduled maintenance and sent a notification to an inbox nobody monitors. A password reset locks out the one person who knows how to access the system. Someone unplugged a cable without knowing what it was connected to.
None of these seem dramatic at first. Until you realize what they could cost your business.
What One of Those Days Actually Costs
Downtime costs money in ways that don’t show up as a single line item; they’re spread across your afternoon, your team’s morning, and your client’s patience.
Your team stops being productive. Every person who can’t access what they need is waiting, improvising, or working on the wrong thing. That time costs money, and it multiplies quickly across multiple people.
Revenue stops or gets delayed. If your payment system is down, you can’t process transactions. If your scheduling software is unavailable, appointments don’t get booked. If your team can’t access client files, billable work doesn’t get done.
Client trust takes a quiet hit. The email that didn’t arrive. The deadline that slipped by two hours. The call that went to voicemail. Clients rarely complain about these things directly. They remember them.
Recovery takes longer than the outage. Getting systems back online is one thing. Catching up on stacked work, handling follow-up, and getting everyone back on track takes longer than the downtime itself. That rarely gets counted either.
Do the Math
According to Atlassian, small businesses lose between $137 and $427 per minute during downtime. That adds up to between $8,000 and $25,000 per hour.
Run your own numbers below and see where you land.
Here’s a simple formula to find your number:
Step 1: Staff cost: Count the number of people potentially affected by downtime. Multiply by their average hourly rate.
Step 2: Revenue impact: Estimate how much revenue your business generates per hour on a normal working day.
Step 3: Recovery time: Add the time it takes to return to normal after the outage ends. In most cases, this is at least as long as the outage itself.
(Affected staff x average hourly rate)
+ estimated revenue per hour
+ recovery time cost
= Your hourly downtime cost
The Number Changes the Conversation
When you know what an hour of downtime costs, every preparedness decision becomes easier to evaluate.
A redundant internet connection looks different when you know a four-hour outage costs more than a year of that connection. A UPS that protects your critical equipment stops looking like an optional expense. A properly configured backup system stops being something you’ll get around to eventually.
The businesses that handle downtime well aren’t the ones with the biggest IT budgets. They’re the ones that did the math and made a few intentional decisions before something went wrong.
Price it out. The number makes the conversation a lot simpler.
