Retirement Age
Change retirement timing for each person in the model to see how earlier or later retirement affects cash flow and portfolio outcomes.
Scenario Explorer for Retirement What-If Modeling
WARPSimLab includes a Scenario Explorer that allows users to change key modeling assumptions and compare how simulation results change relative to a baseline scenario. This makes it possible to explore retirement what-if scenarios without modifying saved data.
Users can adjust inputs such as retirement age, inflation, expenses, market assumptions, and portfolio allocation, then compare results side by side across multiple views, including portfolio results, cash flow results, and combined comparisons.

What the Scenario Explorer Does
The Scenario Explorer allows users to compare how outcomes change when assumptions are adjusted. It provides a structured way to evaluate a baseline scenario alongside a modified scenario using the same simulation framework.
This helps illustrate how changes in retirement timing, spending, inflation, market assumptions, and portfolio composition affect cash flow and portfolio behavior over time.
The purpose is educational exploration. It is intended to show how results respond to input changes, not to recommend a particular financial decision or asset allocation.
Inputs You Can Change
The Scenario Explorer allows users to adjust a set of temporary assumptions and compare results against a baseline scenario in real time.
Inflation Assumptions
Adjust the inflation rate to examine how different inflation conditions affect expenses, withdrawals, and long-term results.
Expense Levels
Increase or decrease expenses using a scenario multiplier to observe how spending changes influence cash flow and portfolio behavior over time.
Hypothetical Market Adjustment
Apply a temporary market adjustment factor to examine how different return environments affect the scenario.
Portfolio Allocation
Adjust portfolio ratios across stocks, bonds, and cash to compare how different allocations behave under the same assumptions.
Fund Expenses
Change fund expense assumptions to see how different cost levels influence results across the simulation period.
Available Comparison Views
The Scenario Explorer supports multiple side-by-side views so users can examine how results differ between an original scenario and a changed scenario.
Cash Flow and Portfolio
Display cash flow on one side and portfolio results on the other to view how income, expenses, and assets evolve together within a single scenario.
Original Portfolio vs Changed Portfolio
Compare the original portfolio simulation on the left with the changed portfolio simulation on the right.
Original Cash Flow vs Changed Cash Flow
Compare the original cash flow simulation on the left with the changed cash flow simulation on the right.
Comparing Portfolio Simulation Results
In portfolio comparison mode, the Scenario Explorer displays an original scenario and a changed scenario side by side. This makes it possible to examine how changes in assumptions affect portfolio values over time.
Portfolio views can include summary metrics such as the share of simulations where total assets fall below $0 during the simulation period. This provides a way to compare how different assumptions affect the distribution of outcomes.
These outputs are hypothetical results based on model assumptions and user inputs. They are educational illustrations rather than predictions or guarantees of future performance.
Comparing Cash Flow Results
In cash flow comparison mode, the Scenario Explorer displays original and changed cash flow results side by side. This makes it easier to observe how changes in retirement age, inflation, or expenses affect income, expenses, taxes, and net cash flow over time.
Because both scenarios use the same underlying structure, the comparison focuses on the effects of the changed assumptions rather than on unrelated differences between scenarios.
Why What-If Scenario Modeling Matters
Personal finance outcomes are sensitive to assumptions. Small changes in retirement timing, expenses, inflation, or portfolio composition can lead to materially different results.
Explore Tradeoffs
Compare how different assumptions interact instead of relying on a single fixed projection.
Test Sensitivity
Examine whether results change materially when one assumption is adjusted while others remain the same.
Learn from Comparisons
Use side-by-side views to better understand how cash flow and portfolio behavior change under different assumptions.
Temporary Scenario Assumptions
Scenario Explorer settings are intended for temporary use. They allow users to test alternate assumptions and compare results without modifying the saved baseline scenario.
This makes it easier to evaluate multiple what-if changes while preserving a consistent starting point for comparison.
