Cash Flow Perspective
• You're investing $500 per month ($6,000 per year).
• Over 30.0 years, that piles up to $190,000 of your own money.
• If your investments actually earned about 8.0% per year on average, the market would add roughly $664,537 on top of your contributions.
• Most of your final balance is growth, not contribution—classic compounding. Keeping contributions steady and staying invested does the heavy lifting.
