44 Best Cost Benefit Analysis Templates

1. Define scope and time horizon
Clearly state which costs and benefits are included, define the project's time period, and specify the discount rate. Use a consistent horizon across all components to ensure apples-to-apples comparisons.

2. Standardize assumptions and data sources
Agree on uniform units, currency, inflation adjustments, and where data comes from. Document sources and justification to improve transparency and reproducibility.

3. Include sensitivity and scenario analysis
Add one-way and multi-scenario analyses to test how results change with key assumptions. Present best-case, base-case, and worst-case outcomes to show robustness.
