Understanding Compound Interest

The Power of Time

Compound interest works by earning returns on both your original investment and previously earned returns. The longer your money stays invested, the more powerful this effect becomes.

Regular Contributions

Adding money regularly amplifies the compound effect. Even small, consistent contributions can lead to significant growth over time due to dollar-cost averaging and compound growth.

Realistic Expectations

Historical stock market returns average 10% annually, but consider using 7-8% for conservative planning. Remember that actual returns will vary year to year and past performance doesn't guarantee future results.
