About

About the CD Savings Comparison Calculator

This calculator will calculate and compare the interest earnings and annual percentage yield on up to 4 different certificates of deposit.

When shopping for an investment CD it can be very difficult to determine which one is the best, because most of them have different interest rates, maturity dates, and compounding intervals.

But now that you have found this free online calculator, this once difficult task is now simply a matter of entering each certificate of deposit and letting the calculator convert the confusing differences into comparable results.

If you would simply like to calculate interest earnings and APY for a single certificate of deposit, please visit the certificate of deposit interest calculator, which also includes the answer to the question, "What is a CD?", along with a link to an unbiased source for more in-depth study.
