Perpetual vs subscription: which software licence is better value?

The key difference: a perpetual licence is a one-off purchase, a subscription is rented monthly or annually.

With a perpetual licence (also called a lifetime licence) you pay once and can keep using that version of the programme indefinitely. With a subscription (or SaaS) you pay periodically and the right to use it ends when you stop paying.

The perpetual vs subscription comparison is therefore not just about price, but about ownership, updates, support and what happens when you stop. A perpetual licence gives you a fixed version that keeps working; a subscription gives you access to the latest version for as long as the contract runs.

Some terms you’ll often come across:

• Perpetual with maintenance: you buy the licence once and pay an annual maintenance fee for updates and support. Without maintenance you keep the purchased version but receive no new ones.
• Subscription: a recurring payment that bundles the right to use, updates and usually also cloud storage and support.
• SaaS: software as a service, where the subscription is linked to an account and some features run in the cloud.
• Version lock: the version you buy with a perpetual licence. New features only come in a later version, for which you pay again.

The distinction seems simple, but the consequences run deep. A subscription ties you to a vendor and to ongoing payments, while a perpetual licence makes you independent but places the risk of obsolescence on you. Whoever wants to make the right choice must look at the whole usage period, not just today’s price.

In the short term a subscription is cheaper; in the long term the perpetual licence usually wins.

The core of every cost assessment is the break-even point: the number of years after which the total subscription costs exceed the one-off purchase price. Calculate the total cost of ownership over the period you will actually use the programme.

A simplified formula for the break-even point:

break-even (years) = purchase price perpetual / annual subscription fee

example:
  perpetual        = 500 euros (one-off)
  subscription     = 150 euros per year
  break-even       = 500 / 150 = 3.3 years

If you use the programme longer than the break-even point, the perpetual licence is cheaper, provided you can manage without new versions. If you want to keep running the latest version, add upgrade or maintenance costs to the perpetual option. The break-even point then shifts further back and the subscription becomes relatively more attractive.

To make this concrete, here is a cumulative cost comparison. The perpetual buyer pays 500 euros in year 1 and buys an upgrade of 200 euros every three years. The subscriber pays 150 euros every year.

The table shows the pattern: without upgrades, the subscription overtakes the bare perpetual licence after just over three years. If you do upgrade, both models run closer together and the deciding factor is how often you buy a new version. Calculate your own figures, because prices and upgrade intervals vary widely per programme.

Perpetual gives you ownership and predictability, a subscription gives flexibility and the latest version.

The two models differ on more points than just price. This table sets out the key characteristics side by side.

A perpetual licence is most worthwhile if you work with the same version for years and rarely need new features. A subscription pays off if you always want the latest version, collaborate in the cloud, or want to spread the cost. Both models therefore have a situation they suit; there is no model that wins in every scenario.

Choose perpetual if you work with one version for years and want to limit costs.

A perpetual licence suits these situations:

• You use the programme in a stable way and don’t need the latest features.
• You work on a computer that is not always online, or in an environment where cloud connections are undesirable.
• You want no ongoing commitment and prefer to pay in one go.
• You use older software that still works perfectly, for example a word processor or a graphics programme from a few versions back.
• You manage a fixed workstation that must last for years without changes, such as a CAD machine in a production environment.

The risk of perpetual is that over time you fall behind: new file formats, operating systems or security updates can one day make an old version unusable. So take into account how long the vendor supports the version and whether you still need to exchange files with people running the latest version.

A practical tip: with perpetual software, keep your installation files and licence key safe. If you need to reinstall years later, the download link or physical media may no longer be available. A copy of the installation file and the key in a secure place prevents you from losing a purchased licence when performing a clean install.

Choose a subscription if you always want the latest version, cloud features or low entry costs.

A subscription suits these situations:

• You constantly need the latest features and formats, for example for exchanging files with clients or colleagues.
• You collaborate in the cloud and share files or projects with a team.
• You want to spread the cost and keep the entry threshold low.
• You use the programme only temporarily, for instance for a single project of a few months.
• You want no hassle with updates, backup features or support.

The downside is that costs keep running and you lose access as soon as you stop paying. With many packages the software switches to a restricted mode after cancellation, where you can only open, view and print files. For occasional use that is rarely a problem; for ongoing work the bill adds up.

For temporary use a subscription is almost always the cheapest route. A monthly subscription for a three‑month project costs a fraction of a full purchase, and you simply cancel afterwards. Do watch the notice period and automatic renewal so you don’t accidentally keep paying for a whole year.

Watch out for price increases with a subscription, and hidden upgrade and support costs with perpetual.

The headline price does not tell the whole story. With a subscription the hidden costs lie largely in time:

• Price increase at renewal: the initial rate is not always the rate you will pay years later. Renewals can be more expensive.
• Features locked behind higher tiers: a feature you currently use may be moved to a higher subscription tier when packages are revised.
• Automatic renewal: if you forget to cancel, the contract continues at the then current rate.

With a perpetual licence the hidden costs lie on the maintenance side:

• Upgrades: a new major version is usually a new purchase, sometimes at a reduced upgrade price.
• Support: support is often not included and costs extra, or expires after a number of years.
• Compatibility: a new operating system can make an old version unusable, forcing an upgrade after all.

Include these items in your calculation. A subscription with a low entry price may, after a few price increases, turn out more expensive than expected, while a perpetual licence without upgrades remains cheaper than it appears on paper.

Almost all major vendors have shifted to subscription-only in recent years.

The shift from perpetual to subscription is easy to follow with well‑known packages:

• Adobe: since 2013 Adobe has sold its creative software only through Creative Cloud. Creative Suite 6 was the last perpetual version of Photoshop, Illustrator and InDesign.
• Autodesk: from 2016 Autodesk no longer sold new perpetual licences, and in 2021 maintenance contracts for existing perpetual licences also ended. AutoCAD, Revit and Inventor are now subscription‑only.
• Microsoft: alongside the Microsoft 365 subscription, Microsoft still sells separate Office versions as perpetual licences, such as Office 2021 and Office 2024. With Windows there is also a choice between editions – read more in Upgrading from Windows 11 Home to Pro.
• Affinity: long the best‑known example of affordable perpetual software, but at the end of 2025 it stopped selling perpetual versions.

With Office you can still genuinely choose between a one‑off purchase and a subscription. With most professional design and drafting packages that choice has now disappeared, and even a classic example of affordable perpetual software like Affinity went that way – detailed in Affinity and the end of the perpetual licence. The background to that broader shift is set out in Why software vendors are switching to subscriptions.

What stands out: the programmes that upheld an affordable one‑off purchase longest, such as Affinity, are now cited as the end of that era. For the user this means: where you once could choose, with many professional software titles the choice is limited to the vendor’s subscription.

With perpetual you own a version, with a subscription you rent access.

The biggest fundamental difference lies in ownership. A perpetual licence keeps working, even if the vendor disappears or raises prices. You are not dependent on an active contract. However, you bear the risk that the software becomes outdated over time.

With a subscription you are dependent on the vendor: they determine the price, the features and the terms. Price increases at renewal do happen, and features can shift to more expensive packages. On the other hand, you are never stuck with an outdated version and updates and support are included.

With a subscription, also watch out for automatic renewal. Note the renewal date so you don’t unknowingly continue at a higher rate. That doesn’t apply with a perpetual licence, but you do miss ongoing security updates once support for that version ends.

In practice, a subscription is also a form of dependence on the vendor’s infrastructure. If some features run in the cloud, you need that service to be able to work. With a purely local perpetual installation that doesn’t apply: it runs on your own machine, independent of the developer’s servers.

If the vendor only offers a subscription, three realistic options remain.

More and more packages are subscription‑only. If you still want to avoid recurring payments, these are the options:

• Use an older perpetual version: if you already have a perpetual licence for a previous version, it will keep working. For many tasks a version from a few years ago is more than adequate, as long as it runs on your operating system.
• Choose an alternative programme: for most categories there is a competitor that still offers a one‑off purchase, or a free alternative. Check whether that programme can handle your file formats.
• Use the subscription for a short, targeted period: take out a subscription only for the time you really need it and then cancel. For occasional use this is often cheaper than a full purchase.

Which route suits you depends on how heavily you rely on the programme and whether you need to exchange files with others running the latest version. For professional use with a lot of collaboration an alternative is sometimes impractical; for independent, occasional work it is a perfectly good way out.

Calculate the total cost over your usage period and then decide based on ownership and updates.

Work through these steps to reach a well‑founded decision:

1. Estimate how many years you will realistically use the programme.
2. Calculate the total subscription cost over that period and compare it with the purchase price plus any upgrade costs of the perpetual option.
3. Decide whether you really need the latest version and cloud features, or whether a fixed version will do.
4. Weigh the importance of ownership and independence against flexibility and always up‑to‑date software.
5. Check whether the vendor still offers a perpetual option at all; for many packages it is no longer available.

If you expect long‑term use with limited need for updates, perpetual is usually cheaper. If you want flexibility, collaboration and the latest version, a subscription is the logical choice. The guidelines from vendors such as Autodesk support and Microsoft 365 support give the current terms and prices for each product.

If you are still unsure, start small. For software that is available both as a subscription and as a perpetual licence, you can test with a short subscription whether the programme fits your work, and only then decide whether a one‑off purchase works out cheaper in the long run. That way you make the decision using real user experience rather than price alone.
