Frequently asked questions

Historically a lump sum wins about two-thirds of the time because markets rise more often than they fall. Spreading the money in reduces regret but on average leaves you slightly behind.
For a global equity portfolio, a nominal 7% is a common planning assumption. Subtract your fee here, and consider using a lower real return if you want today's money.
Because compounding is exponential, not linear. At 7% net, money roughly doubles every ten years, so 15 years gives about 2.8x rather than the 1.5x a linear estimate suggests.
