Investment Calculator

The most powerful force in personal finance isn't a high income or a clever strategy — it's compound interest applied consistently over time. The investment calculator makes this visible: enter what you have, what you'll add each month, and your expected return, and see what you'll have in 10, 20, or 30 years. The numbers are often surprising. $10,000 invested today with $500/month at 7% annual return becomes over $680,000 in 30 years. Your total contributions were $190,000. Compounding created the other $490,000 — money that required no work, just patience. This calculator also shows the impact of return rate assumptions. The difference between 6% and 8% over 30 years isn't proportional — it's dramatic. That's why choosing low-cost index funds over high-fee alternatives isn't a minor optimization; over a career, it's often six figures. The inflation adjustment shows what your final balance is worth in today's purchasing power — because $600,000 in 30 years is not the same as $600,000 today. The "real value" figure keeps the projection honest.
