- Use the scenario lab to see which assumption changes the result most.
- Verify taxes, rates, fees, legal rules and market inputs from authoritative sources before making a real decision.
How OpenFileTools processes it
Local processing, explicit choices.
The browser evaluates the published calculation from your inputs and recomputes a bounded sensitivity range around the selected scenario variable. No external market feed or hidden scoring service is called.
