Read the full guideTarget: 3–6 months of essential expenses

Understand the bonus rate conditions
Bonus interest often requires a minimum monthly deposit and no withdrawals.
Check for withdrawal restrictions
Some accounts limit free withdrawals per month — a problem for emergency access.
Read the fee schedule
Monthly account fees and transaction fees can erode modest balances quickly.
