How CalculatorInvest Forecast Scenarios Work
CalculatorInvest forecast pages show scenario ranges to 2030. This educational guide explains how those scenarios are constructed and, importantly, what they are not.
In this guide
- Why forecasts are scenario-based, not predictive
- Optimistic, realistic, and pessimistic cases
- Growth and volatility assumptions
- How to read uncertainty bands responsibly
Forecasts are illustrative scenarios
Our forecasts are illustrative, hypothetical scenarios generated from historical behavior and transparent assumptions. They are not price targets, predictions, or guarantees, and they are intended for education only.
Optimistic, realistic, and pessimistic cases
Each forecast presents a range rather than a single number. A base (realistic) path sits between a more conservative (pessimistic) path and a more favorable (optimistic) path. The spread between them is the point: it shows how much outcomes could differ under different assumptions.
Growth assumptions
Scenario paths are modeled from historical return characteristics. Because the future may not resemble the past, these growth assumptions are clearly labeled as assumptions and should be read as “what if,” not “what will.”
Volatility and uncertainty
Assets with deeper historical drawdowns and higher volatility produce wider scenario bands, reflecting greater uncertainty. A wide band is a feature, not a flaw — it communicates that the range of plausible outcomes is large.
Why scenarios are not predictions
A prediction claims to know the future; a scenario explores possibilities under stated assumptions. CalculatorInvest scenarios cannot account for unknown future events, so they are educational tools for understanding uncertainty rather than forecasts of actual prices. See our Methodology for full detail.
Key takeaway
CalculatorInvest forecasts show bear, base, and bull scenario paths built from historical assumptions. They are educational illustrations of how outcomes could differ—not price targets or promises.
Common mistakes
- Treating the base case as a likely future price
- Ignoring the width of the scenario band
- Comparing forecasts without reading methodology notes
- Using scenarios as a substitute for personal research or advice
