Frequently asked questions

What is multi-decade & legacy horizons in one sentence?
Multi-decade and legacy horizons treat compounding as an institution: spending rules, fee budgets and successor clarity keep the machine intact.
Is this financial advice?
No. Tool-Lifes pages are educational atlases. Decisions need your goals, constraints and, when appropriate, a licensed adviser.
Do I need a high return for compounding to matter?
Higher net rates help, but time and contributions often dominate — especially early. Costs and behaviour can erase a “good” rate.
How should I use the calculator?
Treat outputs as scenario sketches. Vary contribution, rate, fees and inflation to see which lever moves your goal date.
What about inflation?
Always ask whether a figure is nominal or real. A high nominal path can still lose purchasing power.
Are past returns a promise?
No. Illustrations use round teaching numbers. Markets, inflation and taxes change.
Where do fees show up?
In the net rate that compounds. Expense ratios, advice charges and spreads all reduce terminal wealth.
What page should I read next?
From foundations, continue to contributions-vs-rate or fee-drag; for behaviour, open consistency-habit or panic-selling.
