Before you invest a dollar in markets, build a cash buffer. It is unglamorous and it is the single most important step for staying invested through hard times.
Why it comes first
An emergency fund is insurance against forced selling. Without it, one surprise — a car repair, a job loss — forces you to sell investments at the worst possible moment, often at a loss. With it, you ride out volatility because your life is not riding on your portfolio.
How much
| Situation | Target buffer |
|---|---|
| Stable job, no dependents | 3 months of expenses |
| Average | 3–6 months |
| Variable income or dependents | 6–12 months |
Base it on expenses, not income — what it actually costs to keep your life running.
Where to keep it
Not in stocks, and not in your everyday checking. A high-yield savings account keeps it safe, liquid, and earning a little. The goal is access and stability, not return.
Keep the fund in a different account from daily spending so it is not casually drained. Out of sight, out of temptation.
Build it in steps
- Starter buffer — $1,000 (or one month) as fast as you can.
- Clear high-interest debt (see Budgeting).
- Top up to your full target.
- Then invest the surplus on a schedule.
If you spend the fund, refilling it becomes the next priority — before resuming extra investing. It is a buffer, not a one-time task.
