How to Calculate the Real Cost of DIY IT
Handling IT internally looks free until you add it up.
The license fees, the hardware, the subscriptions are visible and easy to see. But what is harder to see is the time, the risk, the mistakes, and the opportunity cost. When these are added to the visible costs, the comparison between DIY IT and a managed alternative looks very different from the initial invoice.
1. The Time Cost Is Rarely Calculated Honestly
Every hour a business owner, operations manager, or non-IT staff member spends troubleshooting a network issue, setting up a new workstation, managing software updates, or diagnosing a performance problem is an hour not spent on the work that generates revenue.
To calculate this accurately:
- Track the hours spent on IT-related tasks over a representative month, including all staff involved
- Multiply by the fully loaded hourly cost of the staff performing those tasks
- Annualize the result
For most SMBs that have not done this calculation, the number is surprising. Team members who value their time at $150 per hour for otherwise revenue-generating roles and spend five hours per week on IT tasks are spending approximately $39,000 per year on IT before any technology costs are counted.
2. The Mistake Cost Is Invisible Until It Materializes
Non-specialists making IT decisions without full context make mistakes that specialists would avoid, due to applying limited knowledge to complex problems.
Common DIY IT mistakes and their cost categories:
- Security misconfigurations that expose systems to breaches: cost ranges from business disruption to legal liability depending on what is compromised
- Backup systems that are not tested and fail during a recovery event: cost is the value of the data lost plus the downtime during reconstruction
- Over-provisioned or wrong-sized cloud infrastructure: cost is the premium paid monthly over a correctly sized environment
- Software compatibility issues from unmanaged updates: cost is the staff time and downtime required to diagnose and resolve
3. The Learning Cost Is Real and Recurring
Technology changes, and the knowledge required to manage it well requires continuous learning, especially in today’s fast-moving VUCA world.
For a non-specialist managing IT alongside other responsibilities, staying current enough to make good decisions requires ongoing time investment in reading, testing, and problem-solving. This time is legitimate and should be counted in the cost calculation.
4. The Opportunity Cost Is the Largest Number
The question that cuts to the core of DIY IT economics is not what it costs to do it yourself. It is what you would produce if you spent those hours on something else.
For a founder or manager spending five hours per week on IT, the relevant comparison is: what is the expected revenue value of five focused hours per week on sales, product development, client relationships, or strategic planning?
In most cases, the opportunity cost of IT time significantly exceeds the cost of outsourcing the same work. The comparison is not IT cost versus zero, but the IT cost versus the value of the alternative use of that time.
5. The Comparison to Managed Services
When all costs are included, the comparison between DIY IT and a managed services model becomes:
- DIY: visible technology costs plus staff time at full cost plus mistake risk plus opportunity cost
- Managed: fixed monthly fee with defined service scope and predictable performance
Most businesses that run this comparison honestly find that the difference is smaller than expected and often reverses in favor of managed services once opportunity cost is included.
The Full Picture
At Smartt, we like saying that DIY IT is more a cost-deferral cost than a cost-saving strategy, with the costs accumulating over time in the form of inefficiency, risk, and opportunity. The decision to manage IT internally should be made with those costs fully visible, not with only the subscription fees in view.
That’s why with SMBs, we try to help them understand what their current IT situation is actually costing them before deciding what to do about it. FlexHours provides a managed alternative that scales with your needs, with associated discount hardware and software purchases.
