Where to Keep Your Emergency Fund
| Account Type | APY | Best For |
|---|---|---|
| High-yield savings | 4-5% | Primary emergency fund |
| Money market account | 4-5% | Primary emergency fund |
| Short-term CDs (3-6 month) | 4-5% | Portion of extended fund |
| Regular savings | 0.5% | Avoid (opportunity cost) |
| Checking | 0% | Only 1 month max |
Don’t put emergency fund in:
- Stock market (too volatile)
- Real estate (not liquid)
- Retirement accounts (penalties, taxes)
Emergency Fund Interest Earnings
| Fund Size | 0.5% APY | 4.5% APY | Difference |
|---|---|---|---|
| $10,000 | $50/year | $450/year | +$400 |
| $20,000 | $100/year | $900/year | +$800 |
| $30,000 | $150/year | $1,350/year | +$1,200 |
Always use a high-yield savings account — don’t leave money in a traditional bank earning 0.5%.
