SaaS ROI Calculator
Build a decision-ready ROI model for a SaaS subscription. Payback period, ROI%, NPV — no signup.
SaaS ROI model
Estimate ROI for a SaaS subscription by modeling costs vs realized benefits over time. Adjust ramp-up and confidence, then share/export results.
Tip: Start conservative — lower realization and longer ramp-up usually reflect reality.
Results
NPV discounts future net cashflows; payback is when cumulative net turns positive.

Benchmarks (sanity check)
SaaS sprawl and unused licenses are common. Use benchmarks as a reality check — then plug in your own numbers.
Benchmarks are informational and may not match your org size/stack. Treat them as ranges, not promises.
Methodology (visual)
We model monthly cashflows: realized benefits grow with ramp-up, then we compute payback, ROI, and NPV.
- Ramp-up matters: benefits rarely start at 100% on day one.
- Realization factor helps keep assumptions conservative.
- If benefits are mostly time saved, treat it as capacity you can redeploy.
- NPV depends on discount rate and time horizon.
