Methodology
We model ROI as monthly cashflows and derive payback and NPV from the cumulative series.
- Separate one-time vs recurring costs and benefits.
- Ramp-up gradually increases recurring benefits until full realization.
- Payback is the first month cumulative net cashflow reaches 0 or above.
- NPV discounts future net cashflows using your annual discount rate.
Common pitfalls
- Keep units consistent (monthly vs annual).
- Don’t forget recurring costs like support, tooling, or licenses.
- Ramp-up affects payback: benefits rarely start at 100%.
- Avoid double counting benefits (e.g., time saved and revenue uplift from the same change).
