An emergency fund is the moat that keeps a bad month from becoming a debt spiral. Three to six months of essential expenses is the standard target.
Keep it in a high-yield savings account — accessible in days, not minutes (which discourages impulsive use), and earning real interest.
Use it for true emergencies: job loss, medical, urgent home or car repairs. Replenish it before any new investing.
Key takeaways
- Target 3–6 months of essential expenses.
- Keep it liquid, in a high-yield savings account.
- Refill it before resuming aggressive investing.
