Tool methodology
How to use investing tools responsibly
A calculator is only as useful as the assumptions behind it. Tools should clarify inputs, limits, and what the result can actually support.
Contribution, return, inflation, fees, taxes, and time horizon assumptions can change results dramatically.
Example: 7% nominal and 4% real returns tell different stories.
- Mistake: treating projections as promises.
Run conservative, base, and optimistic cases before making a decision.
Example: compare 4%, 6%, and 8% return scenarios.
- Mistake: planning around only the best case.
A tool should lead to a checklist, guide, or review action.
Example: fee calculator result should lead to ETF comparison.
- Mistake: calculating without changing the process.
