When is Software Assurance worth paying for?
Last reviewed by the MSLicenseHub Licensing Desk.
Software Assurance (SA) adds roughly 25–29% per year on top of a perpetual Volume License. It is worth it when you actually use the benefits:
- Version upgrades — the biggest benefit. Without SA, every major upgrade is a fresh purchase.
- License Mobility — needed to run server workloads (SQL Server, SharePoint) on Azure or AWS using your existing license.
- Azure Hybrid Benefit for Windows Server and SQL — saves roughly 40% on Azure VM and SQL DB pricing.
- Training vouchers, planning services, 24/7 problem-resolution support.
SA is rarely worth it for desktop apps you do not plan to upgrade. It almost always pays for itself on Windows Server, SQL Server and Exchange Server in 3 years.
Apply this to your deployment
- Product and version
- Agreement rights
- Compliance evidence
Apply this concept to the exact product and agreement. A brand name, activation key or seller description alone does not establish use, transfer or renewal rights.
Decision checklist
| Check | What to record |
|---|---|
| Product and version | Record the full name, edition, version and part number in the quote. |
| Scope of use | Identify the user, device or deployment; count only the metric applicable to this product. |
| Evidence and support | Retain the agreement, invoice and support lifecycle date; perpetual licensing does not mean perpetual support. |

Practical checklist
- Software Assurance (SA) adds new version rights, licence mobility, Azure Hybrid Benefit and some deployment and training benefits.
- It is worth it when you plan to upgrade within the agreement term or need licence mobility in virtualised or cloud environments.
- Some products (such as Exchange Server SE and SharePoint Server SE) require SA or subscription licences to stay current.
- Without SA, perpetual licences keep working but only for the version you bought.
Common mistakes to avoid
- Paying for SA on products you will not upgrade.
- Letting SA lapse and losing Azure Hybrid Benefit or licence mobility.
- Not using included benefits such as planning services.
