What is the Total Cost of Ownership (TCO) for SaaS?

Total​‍​‌‍​‍‌ Cost of Ownership (TCO) for SaaS represents the full cost of a cloud software subscription, including purchase, implementation, operation, and replacement over a specific period. In general, it goes beyond subscription price to include implementation, integration, internal labor, support, security, and switching costs.

SaaS TCO includes both direct expenses paid to a software vendor and internal costs required to operate the platform effectively.

List price normally only reflects subscription/licensing charges. TCO captures these extra expenses supporting and replacing the software. TCO refers to ownership costs; ROI evaluates the financial value of the investment. For example, a SaaS product might have a notable TCO, yet it could yield a return on investment through changes in revenue, productivity levels, or operational expenses.

The most suitable TCO timeline is the anticipated contract length, the effort required to implement the software, the software’s lifecycle, and when the organization changes the software. Models of the TCO based on three- and five-year cycles may provide a basis for plans in more than one period. However, no particular period is a one-size-fits-all benchmark for that category of SaaS. The period consistency and assumptions matter across products.

Running software on-site most of the time means customers must manage infrastructure, including servers, storage, software setup, patching, and ongoing maintenance. SaaS vendors usually relieve customers by operating the underlying service themselves. Cost factors for organizations may include implementation, integration, administration, security, training, support, and vendor management.

Start by selecting an evaluation period and all one-time, recurring, variable, internal, and exit costs that will be expected within that period. For example, a TCO model should consider the expected number of users (if subscription pricing is based on seats). SaaS Total Cost of Ownership (TCO) comprises components such as implementation and migration, subscription and support, internal operating activities, integration, security, compliance, and exit or switching.

TCO is used when buying or renewing a subscription. Procurement officers, finance, IT, and business can evaluate products using a shared cost model and identify assumptions that influence purchase cost later. Besides that, different situations like a greater number of user additions or higher levels of consumption, increased integrations, or a migration done earlier than expected may also be examined.
