Sensitivity analysis

How assumptions move the result.

Stresses the key assumptions in any projection, one at a time, and ranks them by how much they move the outcome. The result is a tornado chart: the assumptions that matter at the top, the ones that do not at the bottom.

It is the honesty tool. Clients see that the plan's fate hangs on two or three assumptions, and exactly which conversations are worth having again next year.

What you see on screen

How far each stressed assumption moves the outcome. Illustrative figures.

In the app this chart is live: every assumption is on screen, editable, and the projection moves as you change it.

Key inputs

  • Any saved projection scenario
  • The assumptions to stress and the ranges to test
  • The outcome measure to track

What it reports

  • Outcome movement for each stressed assumption
  • The ranked tornado view
  • The combined worst-case and best-case corridor
  • Which assumption deserves the most monitoring

Insights it surfaces

Alongside the numbers, the tool writes plain-language findings you can carry straight into the conversation. Example wording, from sample figures:

The projection is most sensitive to the return assumption: 1.00% either way moves the outcome $186,000, four times the effect of the inflation range tested.

Even the combined worst case keeps the income goal funded to age 87, four years past the client's stated minimum.

Every tool, every time

Rates and thresholds come from the verified Australian rate set for the selected financial year. Every run can be saved as a scenario against the client, exported as a client-ready PDF or an Excel workbook with live formulas, and carried into an SOA or ROA. A methodology and audit PDF documents the calculation, and every output carries the compliance block.
