Office 2021 Support Ended. Here's When Buying Software Once Pays

Microsoft ended support for Office 2021 on October 13, 2026, which means Office 2021, a one-time license, no longer gets security fixes, while a Microsoft 365 subscription keeps being updated. If you own Office 2021, 2019 or 2016, the real decision now is what to move to; if you are buying fresh, the question is whether a one-time license pays back before its own support date arrives.

Key takeaways

Office Home 2024 ($179.99 one time) costs less than Microsoft 365 Personal ($99.99 a year) on one computer once you keep it past 1.8 years, and Microsoft's lifecycle page lists Office 2024's retirement date as October 10, 2029.
On two or more computers the answer flips: Personal covers one person on up to 5 devices, so it costs less than two one-time licenses through 2029.
A perpetual license still has an end date: Office 2016 and 2019 lost support on October 14, 2025, and Office 2021 on October 13, 2026.
Some one-time products now carry a term. Photoshop Elements 2027 is a one-time purchase at $99.99, but the license expires 3 years after you redeem it.
Several tools have a free or one-time tier that is enough for many people: Affinity is free for individuals, Windows Security is built in, and Bitwarden has a free plan.

What it means for you

The right answer depends less on the product than on how long you will use it and how many people and computers share it.

Light home user on one computer: a one-time Office license costs less if you keep it two or more years, but it ends at its support date. See the break-even section.
One person, several computers: Microsoft 365 Personal usually costs less than buying a license for each machine. See the break-even section.
Family sharing across devices: Microsoft 365 Family covers up to six people, and a standard Apple Creator Studio plan can be shared with up to five other family members. See the break-even section, the Bitwarden row and the FAQ.
Hobby photographer or video editor: compare a one-time or free tool with the subscription before paying for the full suite; the table shows the gap for Adobe, Affinity and Final Cut Pro.
Small business or freelancer: check that the edition you buy is licensed for business use, and ask a tax professional how to treat the cost.
Student: verified-student pricing exists at Apple and Adobe Elements; see the table.
On an old perpetual version: if it is Office 2016, 2019 or 2021, it is already out of support. See the support section.

Support dates cap a license

A one-time license buys the right to run a specific version, not a promise that the version stays safe. Microsoft's support page says Office 2016 and Office 2019 support ended on October 14, 2025; the apps may keep working, but without security fixes.

Office 2021 followed. Microsoft says support for Office 2021 ended on October 13, 2026, with no further security fixes or updates, and it recommends that home users upgrade. Microsoft's lifecycle page for Office 2021 lists its start as October 5, 2021, roughly five years of support.

Office 2024 has a similar shape. Its lifecycle page lists a start of October 1, 2024 and a retirement date of October 10, 2029, for the Home and Home & Business editions. The Office 2021 page lists October 14, 2026 for a support end Microsoft announced as October 13, so the last day of Office 2024 support may be October 9, 2029. Whenever you buy, the end date does not move, so a later purchase means fewer supported years for the same price.

Break-even: Office Home 2024 vs 365

On Microsoft's comparison page on October 17, 2026, Office Home 2024 was $179.99 as a one-time purchase for 1 PC or Mac. Microsoft 365 Personal was $99.99 a year for one person (or $9.99 a month, which is $119.88 over twelve months), and Microsoft 365 Family was $129.99 a year for one to six people.

break-even years = one-time price / annual subscription price
$179.99 / $99.99 = 1.80 years (Personal, billed yearly)
$179.99 / $119.88 = 1.50 years (Personal, billed monthly)
$179.99 / $129.99 = 1.38 years (Family, if used on one PC)

Illustrative example: you buy on October 17, 2026 and keep the software until the October 10, 2029 retirement date, just under 3 years (2.98 by calendar count).

Years of use	Office Home 2024 (one time)	365 Personal	365 Family
1	$179.99	$99.99	$129.99
2	$179.99	$199.98	$259.98
3	$179.99	$299.97	$389.97

Over the roughly three supported years, Personal costs $119.98 more than Home 2024, and the one-time license works out to about $60 a year. After the retirement date, a fourth year means a new purchase or running unpatched software. To check another product, enter the license price as the purchase cost and the yearly subscription it replaces as the savings in the payback calculator.

The comparison is not like for like. Personal includes 1 TB of storage, ongoing support and Microsoft Defender, and works on up to 5 devices; Microsoft's January 16, 2025 announcement added Copilot with a monthly allotment of AI credits and a $3-a-month US increase for Personal and Family. Home 2024 is a single-computer license with 5 GB of free OneDrive storage and the free version of Outlook. If you need only Word and Excel on one machine, those extras are what the $119.98 buys.

With two computers the answer changes. If both are yours, Personal covers them: $299.97 over three years against $359.98 for two Home 2024 licenses, a break-even of 3.60 years, which is past the retirement date. For two people, Family costs $389.97 over three years, against $359.98 for two licenses, and covers up to six people. Microsoft's post says Copilot in Family goes to the subscription owner only. Existing subscribers can switch to a plan without Copilot; Microsoft described the cheaper Classic plans as available for a limited time, so check whether your account still shows them.

Adobe: a term license in disguise

Adobe's Elements FAQ says the license is a one-time purchase with no additional fees, does not renew, and expires 3 years after redemption. After that the Elements Editor no longer opens, though the Organizer catalog stays accessible. Photoshop itself is available only through a Creative Cloud subscription. The Photography price is a 12-month contract billed monthly, and Adobe's subscription terms charge 50% of the remaining obligation if you cancel after the first 14 days (30% of the annual commitment in California). At $99.99 for three years, Elements is the cheaper path for basic edits; the Photography plan only earns its price if you need Photoshop or Lightroom's catalog and cloud tools.

Apple and Affinity: buying still works

Apple's pages say Final Cut Pro, Logic Pro, Pixelmator Pro, Motion, Compressor and MainStage are still sold as standalone Mac apps. For a single app, buying wins after about 2.3 years, though Apple's Final Cut Pro page says some premium content is available only to Creator Studio subscribers. Affinity removes the question for individuals, though not for AI features.

Apple's student and educator plan is $2.99 a month or $29.99 a year for verified college students and educators, described as a time-limited offer. Adobe lists the Elements and Premiere Elements bundle at $79.99 for students and teachers, against $149.99 for everyone else.

Frequently asked questions

Do old Office apps stop working when support ends?

No. Microsoft says the apps may keep working, but security fixes, updates and phone or chat support stop, so each newly found vulnerability stays unpatched.

Does a Final Cut Pro owner have to move to Apple Creator Studio?

No. Apple's pages say the one-time purchase remains available and existing owners continue to receive updates. What the one-time buyer gives up is some premium content, which Apple reserves for Creator Studio subscribers without listing it in full.

Is Affinity free forever, or only for now?

Affinity's site calls the app free for individuals and gives no end date, but it makes no promise beyond that wording either.

Is a free password manager enough?

For many households, yes. Bitwarden's free plan includes unlimited passwords and devices and sharing with one other user. Premium at $19.80 a year adds a built-in authenticator, file attachments, emergency access and vault health reports.

Can a family share one Apple Creator Studio plan?

Yes, for the standard plan. Apple's page says it can be shared with up to five other family members through Family Sharing, which spreads the $129 a year across a household. The $29.99-a-year student and educator plans are for individual use and cannot be shared.

A five-step check before you buy

Write down how many years and on how many computers you will use the product, and cap the years at the vendor's support or term end date.
Multiply the one-time price by the number of computers, divide by the annual subscription price, and compare the result with that cap.
Count what the subscription adds that you would use, such as storage, apps on other devices or sharing, and what it adds that you would not, such as AI credits.
Look for a free tier first, such as Windows Security, Affinity or Bitwarden Free.
Confirm the price and term on the vendor page at checkout; terms such as Elements' 3-year limit and Microsoft's Classic plan availability change.
