Frequently asked questions

How does compounding help?

Returns are reinvested and earn further returns, so the balance grows faster over time. The longer you stay invested, the larger that effect.

Are mutual fund returns guaranteed?

No. Returns vary with the market and are not guaranteed, so this projection assumes a steady annual return for illustration only.
