Frequently Asked Questions
How do you calculate SaaS ROI?
(Total value − total cost) ÷ total cost, expressed as a percentage. Total cost includes setup plus recurring subscription over your chosen time horizon.
What counts as "value" from software?
Both new revenue the tool helps generate and costs it removes — saved hours, replaced tools, fewer errors, reduced churn. Quantify each in dollars per month.
What is a good ROI for a SaaS tool?
Any positive ROI within your evaluation window is a green light, but strong tools often return 200–400%+ over 12 months once value compounds.
How long should my time horizon be?
12 months is a common default for annual budgeting. For tools with high setup cost, also check whether break-even lands inside your contract term.
Why include setup cost separately?
Setup (implementation, migration, training) is a one-time hit that delays break-even. Separating it shows the true ramp before the tool pays for itself.
