Use this Certificate Calculator to estimate your savings growth
A Certificate is a fantastic savings account that lets you lock in your fixed rate and load up your growth over a specific period of time. Find out what your Certificate will be worth when it matures by using this calculator to project your earnings. Then, you can make plans for how you want to use that extra money. The key is to keep your money deposited for the full term to avoid a penalty for early withdrawal.
