The 50% Rule
The most widely used guideline in the tech repair industry is the 50% rule: if the cost of the repair exceeds 50% of what a comparable new laptop would cost, replacement is usually the smarter investment. For example, if a new laptop with similar specs costs $600, and your repair estimate is $350, it's probably time to replace it.
Tip: Always get a repair estimate before deciding. Many problems that seem serious — like a slow computer or a failing battery — are actually inexpensive to fix.
Repairs That Are Almost Always Worth It
Some repairs are straightforward and cost-effective, even on older laptops:
- Battery replacement: Usually $60–$120 and gives your laptop years of additional life
- RAM upgrade: Adding more memory can dramatically improve performance for $40–$80
- SSD upgrade: Replacing a slow spinning hard drive with an SSD is one of the best investments you can make — typically $100–$200 installed
- Screen replacement: Depends on the laptop model, but often $150–$300 — worth it if the laptop is otherwise in good shape
- Keyboard replacement: Usually $80–$150 for most laptops
Repairs That May Not Be Worth It
Some repairs are expensive enough that replacement makes more sense:
- Motherboard failure: Motherboard replacements often cost $300–$600+ and may not be available for older models
- Liquid damage: Extensive liquid damage can affect multiple components and lead to ongoing problems even after repair
- Structural damage: Severe physical damage to the chassis or hinges can be expensive to repair properly
Warning: Be cautious of repair shops that charge a diagnostic fee and then quote an expensive repair. At My Neighbor Tech, we'll give you an honest assessment — if it's not worth fixing, we'll tell you.
Age Matters
The age of your laptop is a key factor. As a general rule: laptops under 3 years old are almost always worth repairing. Laptops 3–5 years old: evaluate the repair cost carefully. Laptops over 6 years old: replacement is often the better long-term investment, especially if the operating system is no longer supported.
Questions to Ask Before Deciding
Before making your decision, ask yourself:
- Is the repair cost less than 50% of a comparable new laptop?
- Is the laptop less than 5 years old?
- Does the laptop still run the current version of Windows or macOS?
- Are you happy with the laptop's performance (aside from this issue)?
- Would upgrading RAM or adding an SSD solve the problem?
