Three ideas behind every result

Compounding. Growth earns growth, so time matters as much as the rate. The same contributions started ten years earlier can be worth twice as much.

Today's dollars. A million dollars in 30 years buys far less than today. The retirement tool shows results after inflation so you can compare them with today's spending.

Fees and taxes. A 1% yearly fee can take a fifth or more of a portfolio's growth over decades, and the account type decides when tax is paid. The fee and IRA tools show both.

Figures come from IRS announcements for 2026; returns are your assumptions, not forecasts.
