Frequently Asked Questions

How accurate is the "what if I invested" result?

It is an illustration, not a prediction. The result applies one assumed annual return compounded smoothly, while real markets swing year to year. Use it to understand compounding, not to forecast actual outcomes.

Where do the preset return rates come from?

They are rough long-run historical averages - about 10% for the S&P 500, 13% for the Nasdaq, 9% for the total market, 7% for gold, 4% for bonds, and 1% for savings. Past performance does not guarantee future results.

Does this account for fees, taxes, and inflation?

No. The figures are nominal and ignore fund fees, dividend and capital-gains taxes, and inflation. Each of these would reduce your real take-home growth, so treat the value today as an optimistic ceiling.

What is the "return multiple"?

It is the value today divided by the original amount invested. A 4.0× multiple means your money grew fourfold. It is a quick way to see total growth without focusing on the dollar figure alone.
