PC ESU or a New PC? The Cost Comparison Worksheet
In plain English: If you are deciding between paying for Windows 10 ESU or replacing your computer, this page helps you compare the money side in a simple way. It works as a fill-in worksheet, and it sits inside our broader guide to Windows 10 ESU, staying safe and moving to Windows 11.
First safe step: Start the worksheet with your ESU side: what ESU costs you, which can be nothing, and how long is left on it. Then price a basic new PC against it.
If you are deciding between paying for Windows 10 ESU or replacing your computer, this page helps you compare the money side in a simple way. It works as a fill-in worksheet, and it sits inside our broader guide to Windows 10 ESU, staying safe and moving to Windows 11.
The goal here is trust first. The worksheet has no affiliate links mixed into the math, no model picks, and no push toward one answer. You will write down the ESU years you have left, your likely ESU total, and the real first-year cost of a basic replacement PC. If you need the pricing details before you start, see Windows 10 ESU costs and what it covers.
This page is for comparing dollars over the remaining ESU window, not for choosing a laptop or desktop. If your current PC might already qualify for Windows 11, check the Windows 11 checker tool first. If you do end up replacing the machine, we will also point you to what moving to a new PC actually involves.

Start with the decision and the worksheet
The question is simple: is it cheaper to keep your current Windows 10 PC going with ESU, or to replace it with a new computer now? This page is for that money question only. If you need the background first, see Windows 10 ESU, staying safe and moving to Windows 11.
You only need four numbers to start: how many ESU years you would actually use, the yearly ESU price, the price of a new entry-level PC, and any one-time setup costs. Setup costs can include help moving files, a cable or drive, or paid setup from a local shop. Keep it simple and write down real numbers, not best-case guesses.
This worksheet compares total cost over the remaining ESU window. It does not compare speed, screen size, battery life, or other features. For the ESU side, use the current pricing from Windows 10 ESU costs and what it covers. For the new-PC side, if you are not sure whether your current machine can move on, check the Windows 11 checker tool first.
At the end, you will have two totals lined up side by side. That makes the timing decision easier. If the new-computer total looks close, it also helps to know what moving to a new PC actually involves, but the buying advice stays on a separate page so this worksheet can stay focused on the math.
Fill in your ESU side of the worksheet
If you want to compare the remaining Windows 10 ESU cost, start by filling in the time left in the ESU window. Use months if that is easier, then keep the same unit all the way through the worksheet. If you still need setup details, the separate page on Windows 10 ESU costs and what it covers walks through enrollment and coverage.
Next, enter the price for each ESU period you will pay for, such as one year or one month, depending on how the plan is sold in your case. If your setup has a one-time account or enrollment fee, add that too. Put any renewal timing note beside it, so you know when the next payment would land.
Use a simple total: ESU total = period price x number of periods left + any setup fee. If you pay by month, use months left. If you pay by year, use years left. Keep the worksheet plain, and do the math only for the remaining time you actually expect to use.
This side of the worksheet is only for the ESU cost you would carry through the remaining window. If you also want to check safety before you decide, you can compare that with whether staying on Windows 10 is still safe for your use before you move on to the new PC side.
Fill in the new PC side of the worksheet
If you are replacing the PC, write down the full first-year cost before you decide. Start with the entry PC price, then add sales tax, shipping, setup help if you will pay for it, and any transfer work you expect for files, printers, or accounts.
If you need extra hardware, add it here too. A new monitor, keyboard, mouse, or backup drive changes the real total, even if the PC itself looks cheap on the shelf.
Use one line for each cost, then add them together. If the PC comes with a setup fee or data transfer fee, put that in the same total so you are comparing the same kind of money on both sides of the worksheet.
If you are still checking whether staying on Windows 10 is still safe for your use, do that before you buy. That answer can change whether the new-PC total is worth paying now or whether the remaining ESU window makes more sense for your household.
Compare the totals over the remaining ESU window
Put the two totals side by side before you decide. If your ESU total is lower than the first-year cost of a new PC, the old machine is cheaper for the remaining window. If the new PC total is close, the other factors matter more, especially if you are already checking the Windows 11 checker tool or reading about what moving to a new PC actually involves.
A simple way to compare is to subtract the ESU total from the new PC total. Divide that difference by the number of months left in the ESU window to get a rough monthly gap, or by 12 for a yearly view if you are comparing a full year. That turns a big one-time number into something easier to judge.
There is also a break-even point. If you only have a short time left in ESU, the old PC may win on price even if the new PC is faster. If you plan to stay on Windows 10 for a longer stretch, the new PC can start to make more sense because the extra cost buys newer hardware, more storage, and Windows 11 support.
Money is only part of the call. A new PC can cost more and still be the better pick if the old one is slow, low on space, or no longer fits your setup. If you still need help deciding whether staying put is safe for your use, see whether staying on Windows 10 is still safe for your use. If you want the ESU side again, go back to Windows 10 ESU costs and what it covers.
Use the worksheet to make the final call
If your totals are close, the choice usually comes down to time, risk, and how long you want to keep the current PC. A cheaper path can still be the wrong one if the machine is slow, already failing, or won’t support the next version of Windows after the ESU window ends.
If you want a quick sanity check before you decide, use the Windows 11 checker tool first, then compare that result with Windows 10 ESU costs and what it covers. If the PC passes the check and still feels fine, the lower-cost option may make sense. If it fails the check or struggles with basic use, the extra cost of a new PC may buy you fewer headaches.
When you are ready to move on, read what moving to a new PC actually involves so you can plan the handoff without guessing. If you are still asking whether staying on Windows 10 is still safe for your use, use that answer first, then come back to the worksheet and choose the path that fits your budget and your timeline.
The cleanest rule is simple, pick the lower total only when the PC still has enough life left to justify it. If the machine is near the end of its useful life, the cheaper number on paper can cost more in frustration later.
Frequently asked questions
Can I pay for ESU for part of the remaining time and buy a new PC later?
Yes, you can run the worksheet that way. Count only the ESU periods you expect to use before replacing the PC, then compare that smaller total with the new PC total for the same period.
What should I do if the two totals are close?
Let the condition of your current PC decide. If it runs well and meets your needs, changing nothing may suit you. If it is slow, short on storage, or unreliable, replacement may be worth the extra cost.
Conclusion
Keep your filled-in worksheet. It is the record of this decision at current prices, with both options counted over the same period and with no sales link shaping the total. If the gap is wide, the money answer is clear. If it is narrow, the worksheet has still done its job, because the choice now rests on how the PC runs day to day, not on a guess.
Prices and remaining ESU time will change, so redo the two totals before you renew or buy if months have passed. Use the new numbers, not the old ones, and then follow the path you picked without rushing. A decision you can show on paper is easier to trust than one made from memory.
