Same MacBook, wildly different offers. Here's why.
Two people list the exact same MacBook. Same year, same screen size, sold on the same afternoon. One gets an offer that makes them do a little fist pump. The other gets a number that makes them close the tab and mutter something about scammers. Same laptop, on paper. Different money, in practice.
What happened is simple: "a MacBook" isn't one thing. It's a bundle of specific facts, and each one moves the price on its own. Get those facts right and a number stops being a guess. Here's what actually does the moving.
The chip is doing more work than you think
Chip generation is the single biggest lever on your offer, bigger than almost anything else on this page. Since Apple moved MacBooks off Intel processors onto its own M-series chips, the resale gap between an Apple Silicon Mac and an Intel one has turned into a canyon. It's not really about speed on a spec sheet. It's about the fact that an M-series Mac from years ago still runs today's software without complaint, while an equivalent-age Intel Mac increasingly can't.
That longevity is what buyers are actually paying for. An M1, M2, M3, or M4 chip holds value the way a good Intel Mac from 2015 never quite did, because the ceiling on how long it stays useful is so much higher.
RAM and storage: the numbers that quietly double your offer
Here's a detail most sellers don't clock until it's too late: on every Apple Silicon Mac, memory is soldered directly onto the logic board. There's no upgrading it later, which means the RAM your Mac shipped with is the RAM it will always have. An 8GB configuration and a 16GB or 24GB configuration of the identical model, same year, same chip, can be worth meaningfully different amounts, because one of them will keep pace with demanding work for years longer than the other.
Storage works the same way, just less dramatically. Check About This Mac before you fill in a calculator anywhere. Guessing "256 or 512, I forget" costs you accuracy, and accuracy is what gets you a number you can trust.
Screen, chassis, and battery: the stuff you can't hide
After chip, RAM, and storage set the ceiling, condition sets how close you actually get to it. A cracked or badly scratched screen matters a lot, since replacing one isn't cheap. Dents and deep scratches on the aluminium chassis matter less than people assume, cosmetically, but they still count. Battery health matters too, though less than most sellers fear: a MacBook at 70% battery health with everything else in good shape still earns a solid offer. A worn battery is a line item, not a dealbreaker.
Describe what you actually see. Not what you remember from the day you bought it.
Does it even turn on? Start there.
Whether your Mac powers on at all is its own factor, separate from everything above, and it's the one that scares people into not even asking for a quote. Understandable, but wrong. A MacBook that won't boot is worth less than a working one, obviously, but it's very rarely worth nothing. The chip, the screen, the chassis, and the logic board still carry value even when the machine won't start. We've written a whole piece on exactly why, if that's the situation you're in: a MacBook that won't turn on is still worth selling.
Where people get the number wrong, in both directions
Overvaluing is the more common mistake. People anchor on what they paid three or four years ago, which is a natural thing to do and also almost entirely irrelevant to what a Mac is worth today. Technology depreciates. That's not news. What surprises people is how much of the original price a well-specced Apple Silicon Mac still holds compared to how PCs of similar age fare.
Undervaluing happens too, usually from the opposite instinct: a scratch or a worn battery, and someone assumes the whole machine is now "used goods," barely worth bothering with. It isn't. Here's an odd, specific fact that says a lot about how Apple actually thinks about its own hardware's longevity: the MacBook Air kept essentially the same wedge-shaped aluminium chassis for the better part of a decade. Apple built that shape to last, on purpose, because the machines inside it were built to last too. Age alone tells you very little. The specifics tell you everything.
So don't guess in either direction. Check the facts.
How to get an actual number instead of a guess
Open About This Mac, note the chip, the RAM, the storage. Have a look at the screen and the chassis in decent light. Check whether it powers on. Then run all of it through our price calculator. It asks exactly what we've covered here, nothing more, and gives you an instant, specific offer, not a vague range. Curious what happens after you accept it? Here's how the whole process works, from courier to payment.
