The True Cost of IT Downtime

The True Cost of IT Downtime

When systems go down, the cost is never just the time it takes to fix them. Downtime cascades through your business in ways that are hard to measure but easy to feel. Understanding the true cost is the first step to justifying the investment that prevents it.

Direct costs

These are the costs you can see immediately:

• Lost revenue — sales that did not happen because systems were down
• Staff idle time — employees being paid while unable to work
• Emergency repair costs — premium rates for urgent response
• Overtime — staff working late to catch up after systems return

Indirect costs

These are the costs that show up later:

• Customer churn — customers who leave after a bad experience
• Reputational damage — the market remembers outages
• Lost data — transactions and communications that were never recorded
• Compliance penalties — if downtime caused a regulatory breach
• Staff morale — repeated outages erode confidence in the business

The multiplier effect

The indirect costs typically exceed the direct costs by a factor of 3-5x. A four-hour outage that costs $10,000 in direct costs may cost $30,000-$50,000 in total impact when indirect costs are included.

How to calculate your cost of downtime

For a rough estimate:

1. 1.Calculate your revenue per hour (annual revenue / 2000 working hours)
2. 2.Calculate your payroll per hour (total monthly payroll / 160)
3. 3.Estimate what percentage of operations stop during an outage
4. 4.Add the cost of emergency IT response

This gives you the direct cost per hour of downtime. Multiply by 3-5 for the total cost.

What this means for investment

If your cost of downtime is $5,000/hour, and you average 20 hours of downtime per year, your annual downtime cost is $100,000-$250,000. A managed IT contract that reduces downtime to 2 hours per year costs a fraction of that.

The question is never "can we afford IT investment?" It is "can we afford the downtime that comes from not investing?"
