Frequently Asked Questions

What rate of return should I use?

The US stock market has historically returned ~10% annually (nominal) or ~7% inflation-adjusted. Use 6–7% for a conservative projection.

Does time or contribution amount matter more?

Time in the market is usually more powerful than the amount contributed, due to compound growth. Starting early makes the biggest difference.
