When Should a Business Replace vs. Repair Office Computers?

The hidden cost of lost productivity when employees wait for slow machines to boot up can be staggering. While buying new hardware seems like a large upfront expense, repeatedly repairing aging systems often bleeds your budget over time in ways that aren't immediately obvious. In this post, we'll break down when it makes sense to repair an office computer and when you're better off investing in new equipment.

The "50% Rule" for PC and Mac repairs

A standard benchmark in IT is the "50% Rule." If the cost of repairing an office computer exceeds 50% of the price of a comparable new machine, you should replace it. This is especially true for systems older than three years.

• Diminishing Returns: Repairing a four-year-old laptop might buy you another year, but components like the motherboard and battery are still aging and likely to fail next.
• Warranty Considerations: New workstations come with manufacturer warranties, which provide peace of mind and predictable maintenance costs.

Security risks of running outdated operating systems in 2026

Using old hardware often forces businesses to rely on older, unsupported operating systems that cannot run modern security software effectively.

1. Unpatched Vulnerabilities: Once an OS reaches end-of-life, it stops receiving critical security patches, leaving your business exposed to zero-day exploits.
2. Compliance Violations: For industries handling sensitive data (like healthcare or finance), using unsupported software can lead to hefty fines and compliance failures.

How to calculate the true ROI of a new workstation

When evaluating the decision, don't just compare the repair invoice to the price tag of a new PC. Factor in the total cost of ownership (TCO).

• Productivity Gains: If a slow computer costs an employee just 15 minutes a day, that translates to over 60 hours of lost productivity per year. At $30/hour, that's $1,800 in hidden costs per employee.
• Energy Efficiency: Modern workstations are significantly more energy-efficient, lowering your office's electricity bills.
• Morale Boost: Employees given fast, reliable tools are generally more satisfied and efficient.
