Why it matters
The fund's job is to buy time without borrowing at 22%. Sized right, a layoff becomes a runway instead of a freefall — and knowing your exact number turns an anxious blur into a target with a date.
The steps
Compute your essential month
Not your normal spending — the survival version with wants paused. For many households it's 60-75% of normal spending.
Pick your multiplier honestly
Two steady incomes and in-demand skills: 3 months is a strong floor. Commission income, gig work, one earner, specialized field, or kids: lean 6.
Build it in layers, not one climb
$500 → $1,000 → 1 month → 3 → 6. Each layer is a real upgrade in safety; celebrate them as finishes, not fractions.
Park it where it's safe and slightly boring
High-yield savings or a money market account with federal insurance. Not invested — this money's job is existing, not growing.
Refill before anything else after use
Using it is the system working. The only rule: the refill jumps the queue ahead of extra debt payments and investing until it's whole.
Worked example: $2,400 essential month
Common mistakes
- Using 'three months of salary' instead of three months of essentials — it overshoots and demoralizes.
- Investing the fund. A market dip and a layoff arrive together often enough to matter.
- Never spending it. Insurance you refuse to use is just anxiety with a balance.
- Stopping retirement match contributions to overbuild past 6 months — the match is part of your pay.
