How to Calculate CD Market Value

Are you trying to figure out the value of a certificate of deposit (CD)? CD market value isn't static just because your interest rate is locked in. That means you'll need to take some steps beyond simply subtracting any withdrawal penalties from what you've accumulated to get your current in-pocket value.

What you're really figuring out when determining CD market value is the total that someone would pay for your CD right now based on market factors. Let's talk about the easiest way to do this if you're thinking about withdrawing CD money in 2020 or 2021.

A CD is a financial product that you put money into for a specific duration. CDs have life spans that typically range from ​three months to six years​. Be prepared to pay penalties if you decide to pull your money out before your CD's maturity date.

When determining the value of your CD, take a glance at your interest rate. When rates go up from the rate you've locked in for your CD, your CD will lose value, and when rates go down from the rate you've locked in for your CD, your CD will gain value. It all has to do with investors seeking options with higher rates of return. You're in a position to get a higher rate locked in if you're able and willing to make a larger deposit.

When determining CD value, your goal is to find the full amount that your CD will be worth at the end of your chosen term. You can use the mathematical formula for adding compound interest by plugging in your own numbers: A = P(1 + r/n)^nt. Here's a breakdown of what the different variables mean:

• 1. "A" is the full value of your CD at the end of your term when you factor in your initial amount and interest.
• 1. "P" is your starting amount (principal).
• 1. "r" is the annual interest rate in decimals.
• 1. "n" is the number of times your interest compounds every year. You may have a daily compounding rate attached to your CD.
• 1. "t" is the number of years until your CD hits maturity.

If that seems too complex, you can find a CD interest calculator tool online that will allow you to get your value by simply plugging in the variables above.

The interest you earn on your CD is considered taxable income during the year that it's earned. That applies even if you don't withdraw your money. If you have a CD, keep an eye out for a 1099-INT (interest income) statement from the bank or credit union you sourced your CD from that will show how much interest was earned for the year.
