Repair or replace? An honest decision guide

Repair shops have an obvious bias: we make money fixing things. So let’s be useful and write the framework we actually use when a customer asks us, honestly, whether a device is worth repairing. We use it on the bench all day.

Test 1, The 50% rule

If the repair quote is more than 50% of the cost of a comparable replacement device, the math starts to tip toward replacing. Above 75%, it almost always wins.

Two caveats: (1) replacement cost is the like-for-like device, not the latest model, be honest about what you’d actually buy. (2) Data has a value too. If the repair preserves five years of photos and the replacement means starting over, the math is different.

Test 2, Is it the device or the support window?

A perfectly fixable phone is useless if the OS no longer gets security updates. Check the support window before you commit to repair. iPhone 8 is still supported. iPhone 6s is not. A MacBook from 2014 can be repaired beautifully and then refuse to install your bank’s app.

Test 3, Is this the first major repair or the third?

Devices age in steps, not curves. The first screen replacement is normal. A second screen, plus a battery, plus a charge port over 18 months is a device telling you it’s tired. When components start lining up to fail, the rest are usually close behind.

One good repair on an otherwise healthy device is almost always worth it. A third repair on a device that’s already had two is usually throwing good money after bad.

Test 4, What does it cost you when it’s down?

A phone you use for two-factor codes and your business calendar costing you a day of work has a real downtime cost. A laptop you only use for evening Netflix doesn’t. Same repair, different math.

If you’re losing revenue without it, fast repair beats cheap repair. If it’s discretionary, take the time to weigh things.

Test 5, Sentimental and ecological value

We won’t pretend this is purely a financial decision. Sometimes the laptop has the only copy of a thesis. Sometimes the phone has your dad’s last voicemail. And sometimes you just don’t want to throw a working machine into landfill over a $20 part. All of these are valid reasons to repair.

A device that gets fixed instead of replaced keeps roughly 60kg of CO₂ out of the atmosphere, most of the lifetime emissions of consumer electronics is in manufacturing. We mention this not as a guilt trip but as a fact: repair is the green choice when it’s close.

When we tell you to replace

You’ll hear “honestly, replace it” from us in roughly one in ten diagnoses. Common reasons:

• The board damage is too widespread for a cost-effective recovery.
• The repair total exceeds 70% of replacement and the device is more than 5 years old.
• It has structural damage (chassis, hinge) on top of the electrical fault.
• The OS no longer gets security updates for the model.

If we say it, we mean it. A free diagnosis that ends in “don’t bother” is a good day’s work, it saves you money and protects our reputation. That’s not a contradiction; it’s how the shop has stayed open for nine years.
