LOW INTEREST IN CHECKING ACCOUNT: MOST CHECKING ACCOUNTS PAY 0.01%, MEANING EXTRA CASH LOSES VALUE TO INFLATION INSTEAD OF GROWING. HIGH-YIELD SAVINGS ADVANTAGE: MOVING EXCESS FUNDS TO A HIGH-YIELD SAVINGS ACCOUNT CAN EARN 3-4% APY, KEEPING MONEY LIQUID WHILE GENERATING SIGNIFICANT INTEREST. OUT OF SIGHT, OUT OF MIND: KEEP CHECKING BALANCES LOW PREVENTS IMPULSE SPENDING, WHILE STORING MONEY IN A SEPARATE ACCOUNT MAKES IT FEEL MORE UNTOUCHABLE.
