Is investing monthly better than investing all at once?

Historically, investing a lump sum right away returns more in most cases, because markets rise more often than they fall. But monthly investing smooths the purchase price, protects against the worst timing and matches how people actually save: from their paycheck, month after month.

How is the annual return calculated?

With spread-out contributions, the multiple of the amount invested does not tell the whole story: the last dollars had only a few months to grow. The IRR (internal rate of return) is the average annual return that, applied to each contribution from its date, produces the final value.
