SaaS ROI Calculator
Use this SaaS ROI calculator to compare a software subscription cost with estimated time savings and extra monthly revenue. The result is a planning estimate and depends heavily on realistic input assumptions.
Formula
- Monthly gross benefit = hours saved x hourly value + extra monthly revenue
- Monthly net benefit = monthly gross benefit - monthly software cost
- Annual ROI = annual net benefit / annual software cost x 100
- Payback period = monthly software cost / monthly gross benefit
Example calculation
If software costs $500 per month, saves 20 hours valued at $50 per hour, and contributes $750 in extra monthly revenue, estimated monthly net benefit is $1,250 and annual ROI is 300%.
FAQ
Why include hours saved?
Time savings can be a real operational benefit when those hours are used productively. The hourly value should be a conservative estimate.
Can SaaS ROI be negative?
Yes. If estimated benefits are lower than the subscription cost, monthly net benefit and annual ROI can be negative.
Does this prove a tool will pay for itself?
No. It models assumptions. Actual adoption, implementation quality, and business context can change the outcome.
