Savings accounts and CDs
See how fast your emergency fund or other cash savings could grow in a high-yield savings account, compared with the national average savings rate.
This calculator shows how much your emergency fund or other short-term savings could earn in a high-yield savings account (HYSA) with a starting deposit and monthly additions. It also compares the result with the FDIC national average savings rate (0.42% APY).
Say you move $15,000 plus $400 a month from a traditional bank paying 0.42% APY to an online HYSA paying 4.50% APY. Over three years that earns about $2,800 more in interest, and the money stays FDIC-insured up to the limits.
