Laptop upgrade cost calculator

Six numbers put the two options on the same basis: the value each laptop consumes plus the cash each one needs. Nothing leaves your browser.

What each field means. Price is what you would pay today, before tax. Resale is what your current machine sells for now, not what you paid. Years is the horizon you would actually keep the new machine, not its maximum life. Repairs is your annual average over the last three years. New machine resale is what you expect to get for it at the end. Income is optional and only used for the affordability percentage.

The question is never "is the new machine better". It is "which option costs me less per year, once I count everything".

Most upgrade decisions get argued with the wrong numbers. People compare the sticker price against a repair bill, or the monthly cost of the new machine against nothing at all. Both comparisons flatter whichever side the person already wanted.

The comparison that actually holds

Owning anything costs two things at once: the value it loses while you own it, and the money you spend keeping it running.

• The new laptop consumes value by depreciating: it is worth less every month, and that decline is the real cost, not the sticker price.
• The current laptop consumes value in two ways: repairs, and the resale value of the old machine that quietly evaporates because nobody bought it.

Put both on the same annual basis and the argument usually gets smaller than people expect, sometimes in the direction they did not want.

What the fields mean

The resale value of the current machine is not a bonus, it is the price of keeping it. If it sells for 650 today and is worth nothing in five years, keeping it costs about 130 a year in lost value alone, before a single repair.

The new machine's end value is the same idea in reverse. Enter what you honestly expect to get for it when you are done, and the calculator charges you only the difference.

Reading the result

Six numbers, because they answer different questions. Net cash today is what leaves your account. Cost per year on each side is the comparable pair. The difference tells you which is cheaper and by how much. Break-even only exists when buying is the cheaper option per year, and it tells you how long the upfront outlay takes to be repaid by that annual saving.

If break-even shows "none", the upgrade is not a saving at any horizon. That is not a reason to avoid it. It is a reason to stop pretending it is one.

When this calculator does not apply

It prices a personal purchase, and it assumes you can sell the old machine. If the machine is leased, bought through a business account with depreciation rules, or kept as a spare, the arithmetic changes shape and this page will mislead you.

It also cannot see promotions. A trade-in credit, a carrier subsidy or an education discount can move the buy side by hundreds, and none of them are inputs here. If one applies to you, enter the effective price rather than the list price.

Finally, it assumes money is the deciding factor. If the current machine costs you working hours, the downtime is worth more than the difference this page computes, and the decision is already made.
