How Much Downtime Can You Really Afford?
If your business experienced an hour of unexpected downtime tomorrow, what would it cost?
Most business owners have an answer in mind. It’s usually lower than the real number.
Downtime isn’t just lost productivity. It affects revenue, employee efficiency, customer relationships, and the time it takes to get your business back on track.
The good news is you don’t need complicated reports or spreadsheets to estimate the impact. A few simple calculations can give you a much clearer picture.

A Simple Downtime Calculator
Work through these four categories to estimate the cost of a single outage.
1. Lost Revenue
Start with your average revenue per business hour.
A quick estimate is to divide your annual revenue by approximately 2,000 working hours.
Example
- Annual Revenue: $2,000,000
- Average Revenue Per Hour: $1,000
If your team can’t process orders, serve customers, or complete billable work, that revenue may be gone for good.
Your estimate: $_____ per hour
2. Lost Productivity
How many employees depend on technology to do their jobs?
Multiply the average hourly employment cost (wages plus benefits) by the number of employees affected.
Example
- 10 employees
- Average hourly cost: $30
- Productivity impact: $300 per hour
Now combine your revenue loss and productivity loss.
Subtotal: $_____ per hour
3. Recovery Time
Getting systems back online doesn’t mean business is immediately back to normal.
Your team still has to:
- Catch up on missed work
- Respond to delayed customers
- Verify data
- Get projects moving again
A good rule of thumb is to add 50% for recovery time.
Estimated downtime cost
Subtotal × 1.5 = $_____
4. Customer Impact
This is the hardest cost to calculate, but often the most important.
Think about what happens when customers can’t reach you.
- Missed sales opportunities
- Delayed responses
- Interrupted service
- A customer who decides to call someone else
Ask yourself one simple question:
What is one customer relationship worth to your business?
Putting the Numbers Together
Here’s a simple example.
A 20-person accounting firm generates $3 million annually.
- Lost revenue: $1,500/hour
- Lost productivity: $6,750/hour
- Subtotal: $8,250/hour
- Including recovery time: $12,375/hour
That’s over $12,000 for a single hour of downtime, before considering long-term customer impact.
The Cost You Don’t See
Downtime rarely shows up as one obvious expense.
Instead, it’s spread across missed opportunities, delayed projects, reduced productivity, and frustrated customers. Those hidden costs are why downtime is so often underestimated.
Once you’ve calculated your number, ask yourself this:
How many hours of downtime would it take to cost more than a year of proactive IT management? For many businesses, the answer isn’t very many.
