Every financial advisor says 3-6 months of expenses. But that number is made up. Here is how to calculate YOUR actual number.
After looking at the evidence, a few things stood out to me.
The Formula Most People Should Use
Emergency Fund = Monthly Essential Expenses x Job Search Duration x Risk Multiplier
Related: evidence-based teaching guide
- Monthly essentials: Rent + food + utilities + insurance + minimum debt payments. NOT your total spending.
- Job search duration: Industry average time to find equivalent job. Tech: 3-4 months. Healthcare: 1-2 months. Senior roles: 6-9 months.
- Risk multiplier: Single income household = 1.5x. Dual income = 1.0x. Freelancer/contractor = 2.0x.
Examples
| Situation | Monthly Essential | Search | Multiplier | Target |
|---|---|---|---|---|
| Dual income, stable jobs | $3,000 | 3 mo | 1.0x | $9,000 |
| Single income, tech | $4,000 | 4 mo | 1.5x | $24,000 |
| Freelancer | $3,500 | 3 mo | 2.0x | $21,000 |
Where to Keep It
High-yield savings account (4.5%+ APY in 2026). NOT invested. NOT in crypto. NOT locked in CDs. Liquidity is the entire point.
