CAGR

Compound Annual Growth Rate — the smoothed yearly return that would take you from your starting value to your ending value over the period.

Real vs nominal return

Nominal return ignores inflation; real return subtracts it. Only real return reflects future purchasing power.

Dollar-cost averaging

Investing a fixed amount on a regular schedule. Reduces timing risk and smooths out entry prices over long horizons.

Expense ratio

The annual fee a fund charges as a % of assets. Even 0.5% higher fees can cost tens of thousands over 30 years.

Safe withdrawal rate

The % of a retirement portfolio you can withdraw yearly without running out — the classic 4% rule is a starting point, not a guarantee.

• Confirm the account type (Roth, Traditional, taxable) matches your tax strategy.
• Capture the full employer match before contributing anywhere else.
• Stress-test the plan at a 2% lower return and higher inflation before relying on it.
• Set an automatic contribution and an annual step-up on your raise date.
