Emergency Fund: 3 vs 6 Months Debate

"Three to six months of expenses" is the canned answer to emergency fund sizing. The actual right number depends on your situation.

Why an Emergency Fund

Without a buffer, every car repair, vet bill, or job loss becomes a credit card balance compounding at 22%. The fund's job is to prevent the cascade.

Calculate Monthly Need

Add up only essential expenses:

• Housing (rent or mortgage + insurance + property tax)
• Utilities, internet, phone
• Groceries (not dining out)
• Insurance premiums
• Minimum debt payments
• Transportation to work

This is typically 60-70% of normal monthly spending.

When 3 Months Is Enough

• Dual income household; both jobs are stable
• High-demand skills with quick rehire potential
• No dependents
• Low fixed obligations

When You Need 6+ Months

• Single income
• Self-employed or commission-based
• Specialized skills with longer job search timelines
• Children, dependents, or chronic medical needs
• High mortgage relative to savings

Where to Park It

• High-yield savings account — 4-5% APY in 2026, FDIC insured, instant access
• Money market funds — slightly higher yield, T+1 settlement
• Treasury bills (4-13 weeks) — competitive yield, ladder for liquidity

Avoid stocks, crypto, or anything that can drop 30% the day you need it.
