How to Calculate the ROI of a SaaS Tool
ROI calculations for software are often wishful thinking — here is how to make them rigorous.
Define the problem before calculating the return
ROI calculations fail when they measure the wrong thing. Before calculating return, define the specific problem the tool is supposed to solve — not in general terms but in measurable ones. Customer support tickets per week, time spent on manual data entry per employee per day, lead response time in hours. If you cannot define the problem in a number before purchase, you will not be able to measure whether it improved after purchase.
Measure the baseline before going live
Your ROI calculation requires a before state. Record the current state of your target metric before deploying the tool. How many support tickets per day? How many hours per week on the manual process? What is the current conversion rate in the affected workflow? Without a measured baseline, your post-implementation numbers have nothing to compare to, and any improvement claim is anecdotal.
Account for all costs, not just subscription
ROI equals benefits minus total costs, divided by total costs. Total costs include: subscription price, implementation time, training time, integration development, ongoing maintenance, and the productivity loss during transition. Most ROI calculations undercount costs by 40 to 60 percent by forgetting implementation and training. Use a fully-loaded cost figure to get a realistic return calculation.
Time to positive ROI
Even tools with strong long-term ROI take time to reach payback. Factor in: the ramp period when the tool is deployed but the team is still learning it, the implementation costs that were paid upfront, and the lag between capability availability and workflow adoption. A tool that takes 9 months to reach payback on an annual contract is a different risk profile than a tool that pays back in 60 days. Know the payback period before committing.
