Definitions:

EAR

Effective Annual Rate, the interest rate on an investment or loan that considers compounding within the year.

Compounded Quarterly

A method of calculating interest where the interest earned over a quarter is added to the principal sum, and the next quarter's interest is calculated over the new principal.

Effective Annual Rate

The interest rate on an investment or loan on an annual basis, taking compounding into account.

Compounded Continuously

A method of calculating interest where the frequency of compounding is infinitely small, effectively occurring every moment, leading to exponential growth.
