Understand compound growth without assuming a guaranteed return

Growth can build on prior growth, but actual market returns vary and can be negative.

Words to know

• Investment: Something bought with the hope that it may grow in value or produce income. Its value can also fall.
• Diversification: Spreading money across many investments so one result has less control over the whole account.
• Expense ratio: A yearly fund fee shown as a percentage of the money invested in the fund.

The main idea

Illustrations are planning tools, not promises. Contributions, time, fees, taxes, and returns all affect outcomes.

Use this lesson as a starting point. Check the current numbers, written terms, and dates that apply to you. If a detail is missing, leave it blank until an official record or qualified professional can confirm it.

What can change the answer

• Time horizon, ability to accept loss, and the goal all affect risk choices.
• Diversification can reduce concentration risk but cannot prevent every loss.
• Small ongoing fees can reduce long-term results.

Three things to remember

• Time can amplify results
• Returns are not guaranteed
• Fees compound too

Common mistakes to avoid

• Investing money needed for an important near-term bill.
• Assuming several funds are diversified without checking their holdings.
• Buying an investment that cannot be explained in plain language.

Try these steps

• Compare several return assumptions
• Include fees
• Focus on contribution consistency

Questions to ask yourself

• When will this money be needed?
• What could make the investment lose value?
• What fees are charged and where are they disclosed?
