Common questions

Use the reference tools without losing the full context.

No. They show arithmetic under the assumptions you enter. The output is a scenario or comparison, not a recommendation or forecast.

Blank inputs prevent hidden assumptions from looking like personalized advice. Enter the values that match the decision you are testing, then review how sensitive the result is to those assumptions.

Treat that sensitivity as decision information. Re-check the input, widen the scenario range, and avoid presenting a precise output as certain when the result depends heavily on an uncertain assumption.
