Understanding Investment Returns
Investing consistently over time is one of the most reliable ways to build wealth. Thanks to compound growth, your returns earn their own returns, creating a snowball effect that accelerates the longer you stay invested.
Why Inflation Matters
Inflation is often called the silent wealth eroder. Even at a modest 3% per year, inflation cuts the purchasing power of your money nearly in half over 20 years. That's why this calculator shows both nominal (raw) and real (inflation-adjusted) values — so you can see what your future balance would actually be worth in today's money.
The Power of Consistent Investing
Dollar-cost averaging — investing a fixed amount at regular intervals — smooths out the impact of market volatility. When prices are high, you buy fewer shares; when prices drop, you buy more. Over time, this strategy often outperforms trying to "time the market."
Higher Returns vs Higher Contributions
Use the Compare Scenarios feature to see what matters more: a higher return rate or larger monthly contributions. You might be surprised — in the early years, contribution amount matters more, but over longer horizons, even a small difference in return rate can have a dramatic impact.
- Start early: Even small amounts invested in your 20s can outgrow much larger investments started a decade later.
- Stay consistent: Regular contributions matter more than trying to invest at the perfect time.
- Diversify: Spread your investments across different asset classes to manage risk.
- Keep costs low: High-fee funds can eat into your returns significantly over time. Index funds typically charge 0.03-0.20% vs 1-2% for actively managed funds.
