Investment: Putting funds into stocks, funds, ETFs, real estate seeking returns. Principal loss possible, high return expected (5-15%+ annually), risk exists. Savings pursues stability, investment pursues profitability. Savings suitable for short-term goals (1-3 years), investment for long-term goals (5+ years).

2. 20s: Prime Time to Start Investing

Time is the greatest asset in 20s. Period to maximize compound interest effect. Recommended ratio: Savings 30%, Investment 70%. Savings: Build emergency fund (3-6 months salary). Investment: Actively invest in risky assets like stocks, ETFs, funds. Overcome short-term volatility with long-term investment. Example: Monthly 1M KRW savings → Savings 300K KRW (emergency fund), Investment 700K KRW (US S&P500 ETF, domestic blue chips). Can invest aggressively as enough time to recover from failure. Investment study: Start learning various assets like stocks, funds, real estate.

3. 30s: Balanced Asset Allocation

Savings: Build short-term goal funds (marriage fund, jeonse deposit, home down payment). Investment: Long-term retirement asset building (stocks, ETFs, pension savings). Example: Monthly 2M KRW savings → Savings 1M KRW (2-3 year goal funds), Investment 1M KRW (long-term investment). Balance stability and profitability: 50% of total assets in safe assets (savings, bonds), 50% in risky assets (stocks, ETFs). Rebalancing: Readjust asset ratios 1-2 times annually.
