Why this tool is useful
Use Security Scan Compound Projection Calculator to plan security scan without hiding the inputs behind a generic black-box estimate; it is especially useful when comparing two explicit scenarios.

Security Scan calculator to project repeated percentage change over a chosen number of periods. Runs locally with visible inputs and assumptions.
Ready. Your working data stays in this browser.
Use Security Scan Compound Projection Calculator to plan security scan without hiding the inputs behind a generic black-box estimate; it is especially useful when comparing two explicit scenarios.
The browser validates each numeric field, then uses a fixed expression tree to project repeated percentage change over a chosen number of periods. It performs no network request and never executes user-supplied code.
The built-in security scan example reports 1157.625 for the primary result, so the method can be checked before entering your own scan targets values.
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
