**Compound Interest**: If you deposit $20 into a high-yield savings account with a 2% interest rate, compounded daily, you'll earn approximately $0.40 in interest over a month, bringing your total to $20.40.

**The Power of Small Investments**: Digit, an investment app, can help you invest small amounts of money by rounding up your transactions to the nearest dollar.

This strategy, known as "micro-investing," can add up over time.

**High-Yield Savings Accounts**: Online banks like Charles Schwab and Fidelity offer high-yield savings accounts with competitive interest rates.

These accounts are FDIC-insured, meaning your deposits are insured up to $250,000.

**The Rule of 72**: This financial rule estimates how long it takes for an investment to double in value based on the interest rate.

For example, if you have a 2% interest rate, it would take approximately 36 years for your investment to double.

**Dollar-Cost Averaging**: Investing a fixed amount of money at regular intervals can help reduce the impact of market fluctuations.

This strategy can lead to lower overall costs and increased returns over time.

**Risk-Return Tradeoff**: Investments with higher potential returns often come with higher risks.

Understanding this tradeoff is crucial when deciding where to invest your $20.

**Micro-Savings Apps**: Apps like Qapital and Empower use gamification and psychological hacks to help you save money.

For example, Qapital's "52-week rule" encourages you to save an amount equal to the number of the week (e.g., Week 1: Save $1, Week 2: Save $2, and so on).

**Survey Sites**: Websites like Survey Junkie and InboxDollars can help you earn money by completing surveys.

While the returns are low, it's a way to monetize your spare time.

**Flipping Items**: Buying underpriced items and reselling them online can be a profitable venture.

However, it requires research, patience, and an understanding of market demand.

**Digital Products**: Creating and selling digital products, such as ebooks or courses, can be a lucrative way to turn a small investment into a larger sum.

**Opportunity Cost**: When deciding where to invest your $20, consider the opportunity cost – the potential return on investment you could have earned if you had invested elsewhere.

**Time Value of Money**: The sooner you start investing your $20, the more time it has to grow.

Even small, consistent investments can add up over time, thanks to the power of compound interest.
