What interest rate should I use?

For a high-yield savings account, use 4–5%. For a stock market index fund, historical averages are 7–10% annually. Use a conservative rate for planning purposes.

How powerful is compound interest?

Saving $200/month at 7% for 30 years grows to approximately $227,000 — even though you only contributed $72,000. The rest ($155,000) is interest on interest.

When should I start saving?

The earlier the better. Starting at 25 vs 35 with the same monthly contributions can result in nearly double the final balance due to compound interest over time.
