How to Calculate ROI (Return on Investment): Formula & Free Calculator
Return on Investment (ROI) measures the profitability of an investment relative to its cost. For SaaS founders, it helps evaluate marketing campaigns, tool purchases, and feature development decisions.
The ROI formula
ROI = ((Revenue from Investment - Cost of Investment) / Cost of Investment) x 100. For example, if you spend $1,000 on content marketing and it generates $4,000 in new MRR over 6 months, your ROI is 300%.
For recurring revenue businesses, calculate ROI over the customer lifetime, not just the first month. A $100 marketing spend that acquires a customer with $600 LTV has an ROI of 500%.
Common ROI calculations for SaaS
Marketing ROI: compare ad spend or content investment against the LTV of acquired customers. Tool ROI: compare the cost of a SaaS tool against the time it saves valued at your hourly rate. Feature ROI: compare development cost against the incremental revenue the feature generates.
