The investment growth is based on this rate. ~7% is a broad world index's long-run average — try others:

Goldie: This is opportunity cost. Money you spend can't grow — but invested, even tiny amounts snowball, because each year's gains earn gains too. A one-time sum invested today grows the most; a habit adds money gradually, so it multiplies less but you invest far more in total.

⚠️ Educational only — not financial advice. “Invested” compounds at the average yearly growth you pick (default 7% — a broad world-stock index's long-run average); “savings” uses 1.5%. Real returns vary year to year and can be negative.
