Frequently asked questions

Over long horizons, usually yes. Money invested early compounds for the whole period, so a five-year delay removes both the contributions and all the growth those contributions would have generated.
The catch-up figure shows it. Because the remaining period is shorter, the monthly amount has to rise substantially β€” often by 50–100% β€” to reach the same end value.
Invest something smaller immediately and increase it later. Starting at a lower amount beats waiting, because every month invested adds a full horizon of compounding.
