Need help with finding what compounded quarterly is

Compounding means at the end of every term, the interest adds up to the Principal Amount. Compounded quarterly means, you do it for every three months. So after every three months, your interest will be added to principal and the total sum becomes the principal for next quarter.

Does this help you any??
