What-if analysis
What-if analysis is the practice of testing how changes in assumptions would affect financial outcomes. For what-if analysis, the useful boundary is the driver, assumption, source data, owner, time period, scenario logic, and decision the model is meant to support.
Also known as what-if modeling, what if analysis
Why it matters
Understanding what-if analysis matters because planning only improves decisions when assumptions, drivers, owners, and time periods are explicit enough to revisit when actuals arrive. Pluvo answers what-if questions against live, connected data and recomputes the full impact deterministically, so the answer is reproducible rather than a manual workaround.
In practice
Planning example
Teams use what-if analysis when a forecast, budget, or scenario needs an assumption that can be revisited. The finance team should know the driver, source data, owner, and period before using it in a model.

In practice, teams should define what-if analysis with a clear source, owner, time period, and decision before they use it in reporting, planning, or operating reviews.

A strong workflow for what-if analysis separates the definition from the action: first agree what the term means, then decide how it is measured, when it changes, and who is accountable for the next step.

FAQ
What is what-if analysis?
What-if analysis is the practice of testing how changes in assumptions would affect financial outcomes. For what-if analysis, the useful boundary is the driver, assumption, source data, owner, time period, scenario logic, and decision the model is meant to support.
How is what-if analysis used in finance?
To use what-if analysis, start with the decision, then confirm the source data, timing, calculation logic, and owner. The analysis is strongest when a reviewer can trace the answer back to the records that produced it.
