Repair, Replace, or Migrate? A Cost Worksheet for an Aging Computer

Repair, replacement and Linux migration should be compared with the same worksheet.

Otherwise one option gets quoted as a full cost while another is described as "free."

Linux itself may cost nothing to license.

Migration still has labor, compatibility and transition costs.

Column 1: repair the existing system

Record the costs required to keep the current operating system path useful.

Possible items include:

• SSD replacement;
• RAM upgrade;
• battery replacement;
• cooling service;
• operating-system repair;
• software reinstall;
• data migration;
• security-support costs.

Do not include a part simply because it would be nice to upgrade.

Only include what the repair path actually requires.

Column 2: migrate the existing hardware to Linux

Record:

• hardware repair still required;
• backup time;
• software audit;
• peripheral testing;
• Linux installation;
• data restoration;
• application setup;
• user training;
• any replacement software;
• any device that must be replaced.

Linux does not erase hardware-repair costs.

If the SSD is failing, both Windows and Linux need a healthy drive.

Column 3: replace the computer

Record the full replacement cost, not only the advertised computer price.

Include:

• new computer;
• data transfer;
• software licenses;
• adapters or docking changes;
• peripheral replacement;
• setup;
• user transition time.

A new machine may also include warranty value and a longer expected support horizon.

Those belong in the comparison.

Add remaining useful life

Cost without time is misleading.

Estimate how long each option is expected to remain practical.

A $150 repair that buys six stable months is different from a $150 repair that buys three years.

The estimate should consider:

• hardware age;
• parts availability;
• battery or power-supply condition;
• storage health;
• software support;
• workload growth.

Do not pretend the estimate is exact.

Use a realistic range.

Add workflow risk

Create a separate line for required applications and devices.

For each option, mark:

• confirmed working;
• needs testing;
• replacement required;
• unavailable.

One unsupported business application can outweigh a small hardware-cost advantage.

Add support-path risk

Windows 10 standard support ended in October 2025.

Windows 11 has specific hardware requirements.

Linux distributions also have defined support periods.

Record which supported path each option actually provides.

"Still boots" is not the same as "has a reasonable maintained operating-system path."

Compare annualized cost carefully

If desired, divide the expected total by the estimated remaining useful years.

That can reveal false bargains.

Example structure:

Option	Up-front Cost	Expected Useful Life	Major Risk
Repair current OS	estimate	range	support/hardware
Migrate to Linux	estimate	range	compatibility
Replace	estimate	range	purchase cost

Do not use fake precision.

The worksheet is for exposing assumptions.

Include the value of owner time

A technically possible migration can still be expensive if it requires many hours of retraining or repeated troubleshooting.

Likewise, buying a new machine has setup time.

Time belongs in the comparison even when no invoice is issued.

The worksheet does not choose for you

Its job is to prevent invisible costs.

A Linux migration may win when:

• hardware is healthy;
• Windows support is the limiting factor;
• required workflows test successfully.

Replacement may win when:

• multiple components are failing;
• required software is incompatible;
• power use or reliability is poor.

Repair may win when:

• the failure is small;
• the supported operating-system path remains good;
• the machine otherwise meets the workload.

The value is not in a universal answer.

It is in putting all three answers on the same sheet.
