When Should You Replace Business Computers?
Plan to replace business computers every 4-5 years. Laptops typically need replacement sooner (3-4 years) due to battery degradation and more wear. Staggered replacement (25% of devices per year) spreads costs and IT workload.

1The True Cost of Old Computers
Hidden Costs of Keeping Old Hardware
That 6-year-old desktop "still works," but is it really saving money?
Productivity Loss
Slow boot times: 2-5 minutes (vs. 30 seconds on SSD)
Application lag during multitasking
More time waiting = less time working
Conservative estimate: 30 minutes/day lost productivity
At $40/hour, 30 minutes/day = $5,000/year per employee
Increased Support Costs
Older hardware fails more often
Parts harder to find
More IT time spent troubleshooting
More user frustration = more support tickets
Security Risks
Old hardware can't run current OS
Windows 10 support ends October 2025
Unsupported systems = unpatched vulnerabilities
One breach can cost more than replacing every PC
Compatibility Issues
New software may not run
Video conferencing struggles
Can't use new peripherals
Integration problems with cloud services
2Signs You Need to Replace
Definite Replace Indicators:
Operating System End of Life
Windows 10: October 2025 (no security updates after)
Windows 8.1: Already unsupported
Running unsupported OS = security risk
Hardware Failures
Multiple repairs on same device
Intermittent problems that can't be diagnosed
Components failing (fans, batteries, screens)
Can't Meet Basic Requirements
Insufficient RAM for current applications
No SSD (mechanical hard drives are obsolete)
Can't support current security software
Probably Replace:
Age + Symptoms
Over 5 years old AND experiencing slowness
Over 4 years for laptops (battery degradation)
User Complaints
Consistent complaints from the same users
Workarounds being used (personal devices, avoiding tasks)
Business Changes
New software requirements
Video conferencing becoming standard
Remote work needs better hardware
3Lifecycle Planning
Staggered Replacement Strategy
Instead of replacing everything at once (expensive and disruptive), stagger replacements:
The 25% Rule
Replace 25% of your computers each year on a 4-year cycle.
Example: 40 computers
Year 1: Replace 10 oldest machines ($12,000)
Year 2: Replace next 10 oldest ($12,000)
Year 3: Replace next 10 ($12,000)
Year 4: Replace remaining 10 ($12,000)
Year 5: Start cycle again with Year 1 machines
Benefits:
Predictable annual budget ($12,000/year vs $48,000 spike)
Spread IT workload for deployments
Always have machines under warranty
No mass end-of-life crisis
Recommended Lifecycle:
Desktops: 5 years
Laptops: 4 years
High-use laptops (sales, executives): 3 years
