Short-term goals: high-yield savings or short CDs. Long-term: a diversified portfolio.

How big should my emergency fund be?

Most planners suggest 3–6 months of essential expenses, more if income is variable.

What's APY?

Annual Percentage Yield — the rate including compounding. Always compare APYs, not APRs.

Are bank accounts safe?

FDIC-insured accounts are protected up to $250,000 per depositor per bank per ownership category.

Should I lock money in a CD?

Only if you don't need it during the term — early withdrawals carry penalties.
