Common Mistakes to Avoid
⚠️
Using retirement savings as emergency fund
Emergency fund must be liquid (not in 401k or IRA). Withdrawing from retirement incurs taxes + 10% penalty, effectively losing 30-40% of the value.
⚠️
Keeping emergency fund in checking account
HYSA (High-Yield Savings Account) earns 4-5% APY vs 0.01% in a standard savings account. $20,000 earns $800-1,000/year in a HYSA with no additional risk.
⚠️
Not separating emergency fund from other savings
Keep emergency fund in a separate account labeled 'Emergency Only' to avoid dipping into it for non-emergencies.
