Perpetual vs Subscription Software: A Cost Analysis Over 5 Years
The shift in the software industry from perpetual licensing to subscription models has been one of the most significant — and for many users, most frustrating — changes of the past decade. For software that professionals depend on every day, the difference between owning a licence outright and paying a monthly or annual subscription is not just a pricing question. It affects cash flow, software continuity, business risk, and the total amount spent over a software’s useful life.
This article takes a clear-eyed look at both models, works through real cost comparisons over a five-year horizon, and helps you make an informed decision about which approach suits your situation.
What Perpetual Licensing Actually Means
A perpetual software licence means you pay once and can use the software indefinitely. You own the right to use the version you purchased for as long as you choose. There is no expiry date, no renewal, and no risk of losing access if you choose not to pay again. If you purchase Microsoft Office 2024 Professional Plus as a perpetual licence, you can use it in 2024, 2030, or 2035 without paying anything more.
The tradeoff is that perpetual licences do not include automatic access to future versions. If Microsoft releases Office 2027 with features you want, purchasing a perpetual licence of Office 2024 does not give you that. You would need to purchase the new version separately. However, for many business users, the current version of a mature application like Microsoft Office continues to meet their needs for many years without updates.
What Subscription Licensing Actually Means
A subscription licence means you pay a recurring fee — monthly or annually — for the right to use the software during the subscription period. When you stop paying, your access to the software ends. You always have access to the current version while your subscription is active, and updates are included.
The ongoing obligation is both the feature and the risk. The feature is always-current software. The risk is that the cost continues indefinitely — there is no point at which you have finished paying and can stop spending. If your subscription payment fails or you choose not to renew, you lose access to your tools.
Five-Year Cost Comparison
To make this concrete, let us compare the costs of several common software tools over a five-year period under both models.
Microsoft Office
Microsoft 365 Personal (subscription) currently costs approximately £59.99 per year in the UK, or £5.99 per month. Over five years, this totals approximately £300.
A perpetual licence for Office 2024 Professional Plus from GetRenewedTech costs £29.99. Over five years, you would spend £29.99 once. Even if you chose to upgrade to a new version at the mid-point — say, purchasing Office 2027 when it becomes available — your total spend over five years would be roughly £60. That is a saving of approximately £240 compared to the subscription model over the same period.
The value of the subscription model is the additional cloud features (OneDrive storage, Teams, the mobile apps). If you genuinely use these, they represent real value. If you primarily use Word, Excel, PowerPoint, and Outlook on a single computer, the subscription features may not justify the ongoing cost difference.
AutoCAD
Autodesk’s move away from perpetual licensing for AutoCAD means that Autodesk’s own retail channel offers only subscription pricing for AutoCAD, which runs to approximately £1,900 per year at full retail price for a single user. Over five years, that is £9,500.
A perpetual-style licence for AutoCAD from GetRenewedTech is available at £39.99. Even renewing annually — treating it as an annual licence — your five-year spend would be approximately £200. The contrast with Autodesk’s retail subscription is stark.
Windows
Windows 11 is a perpetual licence — you buy it once. There is no Windows subscription for individual users (Microsoft 365 for business includes some Windows management features, but the OS licence itself is perpetual). A Windows 11 Professional licence from GetRenewedTech costs £18.99 and covers the life of the machine it is installed on. No ongoing cost.
The Hidden Costs of Subscriptions
Beyond the headline subscription cost, several factors make subscriptions more expensive in practice than they appear at first glance.
Price Escalation
Software subscription prices tend to increase over time. Microsoft, Adobe, and Autodesk have all increased subscription prices in recent years. A five-year cost estimate based on today’s subscription price assumes no increases — an assumption that is almost certainly wrong. Perpetual licences, purchased at a fixed price, are immune to retrospective price increases.
Forced Upgrades
When you subscribe to software, you effectively agree to accept updates on the vendor’s schedule. Sometimes these updates bring valuable new features. Sometimes they change workflows, move features you rely on, or introduce interface changes that require relearning. With a perpetual licence, you choose when to upgrade — if the current version meets your needs, you are under no pressure to change.
Data Lock-in Risk
If you use cloud-hosted features as part of a subscription (OneDrive for Office 365, Autodesk Docs for AEC Collection), your data lives in the vendor’s cloud. If you cancel the subscription, accessing those files may require exporting before cancellation. This is manageable with good planning, but it is a dependency that does not exist with local perpetual software.
Internet Dependency
Many subscription applications require periodic internet check-ins to verify the licence. Some require continuous connectivity for cloud features. For professionals working in locations with unreliable internet access (construction sites, remote field locations, areas with poor connectivity), this can be a practical problem.
When Subscriptions Do Make Sense
Despite the cost disadvantages for many users, subscriptions are genuinely the better choice in specific situations.
Rapidly Evolving Software
For software that is evolving rapidly and where keeping current genuinely matters — security software, cloud services, AI-powered tools — the always-current nature of a subscription is a real benefit. However, mature desktop applications like Microsoft Office or AutoCAD do not change fundamentally from year to year, reducing the value of always-current access.
Seasonal or Project-Based Work
If you only need software intensively for a specific project or season, subscribing for a few months and cancelling is more cost-effective than buying a perpetual licence. A contractor who needs AutoCAD for a three-month project can subscribe for exactly that period without committing to a full perpetual purchase.
Teams Needing Centralised Management
For larger organisations, subscription licensing sometimes simplifies IT management through centralised licence management portals. Microsoft’s Volume Licensing and Autodesk’s Named User model allow IT departments to assign, reassign, and audit software access centrally. Whether this benefit outweighs the cost premium depends on team size and internal IT overhead.
Making the Decision
To decide which model is right for you, answer these questions:
- How long do you expect to use this software? Shorter duration favours subscriptions; longer duration favours perpetual.
- Do you genuinely need the latest version, or does the current version meet your needs? If the latter, perpetual makes sense.
- Is your work cloud-dependent in ways that require subscription access? If not, perpetual is simpler.
- What is your cash flow situation? Subscriptions spread cost over time; perpetual requires upfront spend (which at these price points is usually not a significant barrier).
- How important is cost certainty? Perpetual licences provide exact cost certainty; subscriptions introduce price escalation risk.
The GetRenewedTech Approach
GetRenewedTech offers a range of professional software at prices that make the perpetual model particularly compelling. Office 2024 Professional Plus at £29.99, Windows 11 Professional at £18.99, and AutoCAD at £39.99 represent significant savings compared to both retail perpetual pricing and subscription alternatives, making the cost case for perpetual licences even more compelling at these price points.
Conclusion
Over a five-year horizon, perpetual software licences are almost always more cost-effective than equivalent subscriptions for professional users with stable, ongoing software needs. The subscription model benefits software vendors by converting one-time purchases into recurring revenue streams — which is why virtually every major software company has aggressively pushed the transition. For individual professionals and small businesses who use the same tools consistently, however, the economics of perpetual licensing remain highly favourable, particularly when purchased at competitive prices.
The Total Cost of Ownership Framework
A rigorous cost comparison should account for total cost of ownership (TCO) rather than just the headline licence price. TCO includes all the costs associated with acquiring and using software over its life: the licence cost, installation and setup time, training costs, upgrade costs, support costs, and any costs associated with data migration or lock-in.
For perpetual software, the TCO analysis typically looks like this over five years:
- Initial licence: one-time cost at year 0
- Possible upgrade: if a new version offers needed features, perhaps once in five years
- Support: typically covered by manufacturer documentation and community forums for mature products
- Total: initial licence cost plus at most one upgrade
For subscription software:
- Annual or monthly fee: compounding year on year, with potential for price increases
- Dependency on connectivity: for cloud-verified subscriptions, internet access is effectively a requirement
- Data portability: if you cancel, ensure you can export and access your data in standard formats
- Total: subscription cost multiplied by five (or more), with price escalation risk
Specific Scenarios Where Each Model Wins
Perpetual Wins For:
Long-term stable businesses: A firm that has been using the same core software stack for a decade and expects to continue using it for another decade benefits enormously from perpetual licensing. Each year without a subscription payment is pure saving. An architectural practice that has been using AutoCAD for twenty years has likely paid for perpetual licences several times over through subscription equivalents if they had subscribed instead.
Software that does not change rapidly: Microsoft Office 2016 is still entirely functional for word processing, spreadsheets, and presentations in 2026. The core functionality of a mature productivity suite does not require annual upgrades to remain useful. A business that purchased Office 2019 Professional Plus is still running perfectly capable software today, at a one-time cost incurred years ago.
Budget-constrained businesses: A small business or sole trader with limited and irregular income benefits from the cost predictability of perpetual licensing. There is no monthly outgoing that stops you working if a payment fails.
Subscription Wins For:
Short-term or project-based use: A freelancer who takes on a three-month contract requiring a specific tool can subscribe for exactly that period. The subscription cost for three months is far less than a perpetual licence purchased for one project.
Software that is genuinely improving rapidly: For tools where significant new features arrive frequently and they matter to your work, keeping current through a subscription has real value. Security software and cloud services fall into this category. Mature desktop design tools generally do not.
Businesses needing the absolute latest version: Some interoperability requirements demand the current version — in sectors where clients require IFC2x3 or newer, for example, using software that is several versions behind may create compatibility issues. For these businesses, the subscription model’s always-current guarantee has tangible value.
A Word on Software Resale and the Secondary Market
One often-overlooked aspect of perpetual licensing is its residual value. Software with a transferable perpetual licence can, in principle, be resold when you no longer need it — reducing your total net cost. The secondary market for perpetual software licences is real and operates through specialist resellers. GetRenewedTech operates in this market, providing professionally managed software at prices that reflect the genuine market value of perpetual licences rather than the premium retail pricing that major publishers charge for their own direct channels.
This is worth factoring into a TCO analysis: a perpetual licence purchase is not purely an expense — it is an asset with some resale value, which subscription spend is not.
