Repair it or replace it? The honest math

First: which problem do you actually have?

“My computer is dying” describes three completely different situations, and the money math is different for each door.

Door one — it’s software-sick. Slow, cluttered, popping errors, “acting weird.” This is the most common by far, it has nothing to do with the machine’s health, and it’s fixed in an hour or two of cleanup — no parts, no shop, no new computer. Walking into a store with this problem is how people buy machines they didn’t need.

Door two — it’s genuinely hardware. A failing drive, a swollen battery, a dead screen, no power at all. Real, physical, and repairable — by a repair shop, with a quote you can do math on.

Door three — it’s simply old. Nothing is broken; the machine just can’t keep up with what software has become. No repair fixes this, because nothing is wrong.

Everything below assumes you know which door you’re at. If you don’t — that’s the single most valuable thing to find out first, and an hour settles it.

The honest math for a hardware repair

Two numbers decide it: the repair quote, and what a suitable replacement actually costs — not the fanciest machine, the suitable one.

The rule of thumb that holds up: a repair under half the replacement cost, on a machine under five years old, is usually worth doing. The computer has years left; you’re buying them at a discount.

Between five and seven years, it depends on what’s failing — one worn part on an otherwise healthy machine can still be sensible; the second repair in a year usually isn’t. Past seven years, hardware repairs rarely pay — you’d be putting a new engine in a car whose transmission is next.

One asterisk in the machine’s favor: age limits are about hardware faults. An older computer that works but crawls often just needs the cleanup from door one — that’s maintenance, not life support, and it’s almost always worth it.

What “replace” really costs beyond the sticker

The price tag is the visible half. The invisible half: getting your life onto the new machine — the photos, the documents, the email, the printer that finally worked, the passwords, the way everything was arranged. Done carelessly, this is where things get lost; done from scratch, it’s days of small frustrations.

Budget for the move the way you’d budget for movers with a new house. (It’s honest to say this is a thing we do constantly — new-computer setup and data moves are a house-call staple — but whoever does it, count it in the price of “new.”)

The decision, on one page

Software-sick → clean it up; spend an hour, not a thousand dollars. Hardware fault, machine under five years, quote under half of replacement → repair it. Hardware fault on a seven-plus-year machine → put the repair money toward the successor, and move in properly. Just old and slow, nothing broken → tune it up first; replace only if it still can’t do your actual jobs. And in every branch: decide once, with real numbers — not in a store aisle with a dead laptop under your arm.
