The inflation adjustment is not a fee. It shows the difference in purchasing power between future dollars and today's dollars.

Future value questions

What is the difference between future value and today's value?

Future value is the nominal amount your investment may reach. Today's value adjusts that amount for expected inflation to express its purchasing power in current dollars.

What expected return should I enter?

Use a conservative long-term annual return rather than relying on one product's recent performance. Compare several scenarios, such as 3%, 5%, and 7%, instead of treating one estimate as certain.

When are monthly contributions added?

The calculator assumes the same contribution is made at the end of each month. Each contribution is added after that month's investment growth is applied.

Does the calculation include taxes and fees?

No. Taxes, trading costs, fund expenses, advisory fees, and currency conversion costs can all reduce actual results.

Why does a higher inflation rate reduce today's value?

The nominal future value remains the same, but faster price increases reduce what that future amount can buy. The inflation-adjusted value therefore appears lower.
