Should you wait for the next model?

Waiting is not free. Six numbers price the pause, so the decision becomes a trade instead of a default.

What each field means. Resale today is a completed-sale price, not an asking price. Expected value after the wait is your honest guess for the same machine later. Months is the gap between now and the purchase you are considering. Repairs is the annual average for the current machine. The two price fields are the model you can buy today and the one you expect after the wait; leave them equal if you do not expect a change.

Every laptop purchase has a sibling question that costs more: should you buy now, or wait for the next model.

Waiting feels free. It is not. While you wait, three things move in the same direction: your current machine loses resale value, it keeps needing repairs, and the model you eventually want may cost more than the one on the shelf today. None of that appears on a product page, because no store is paid to show it to you.

What waiting actually costs

Three numbers, all measurable before you decide.

Resale decay. Your machine is worth a specific amount today. In six months it will be worth less, and the gap is a real loss even though no money leaves your account. This is the largest component for most people and the one they never count.

Repair spend. A machine kept six more months needs whatever it needs. Batteries, fans, storage, and the occasional screen. On average this is smaller than people fear, but it is not zero.

Price movement. Sometimes the next model arrives at the same price, sometimes higher. If it arrives higher, waiting also costs the difference.

Add those three and you get the price of the pause.

What waiting buys

It is not irrational to wait, and this page will not pretend otherwise. Waiting buys three things that are hard to price:

Those are legitimate. The point of the calculator is not to talk you out of waiting. It is to make sure you know what the wait costs, so the decision is a trade rather than a default.

How to read the result

The output is a total and a per-month figure. The per-month number is the useful one, because it is comparable to things you already pay for: a subscription, a monthly transit pass, a coffee habit.

If waiting costs 40 a month and the next model is meaningfully better for your work, waiting is cheap. If it costs 150 a month, you are paying a premium for information that reviews will give you for free within weeks of launch.

What this calculator does not know

It cannot tell you whether the next model is better. It does not know the launch date, the specs, or whether supplies will be constrained for months after launch. It measures the cost of the delay only, and the delay is the part you control.

Enter your own numbers. The defaults are placeholders, not market data.

When this calculator does not apply

It prices a delay you chose. If the current machine has failed or is about to, the real cost of waiting is downtime, and no input on this page captures that.

It also assumes you know roughly what is coming and when. If the next model's launch date is a rumour, the price-after field is a guess and the output inherits that error. Treat it as directional.

And it cannot price a feature you are specifically waiting for. If the next model has the one thing your work needs, the honest answer is that you are not buying a laptop, you are buying that capability, and the arithmetic is beside the point.
