A CD maturity calculator shows both when your certificate of deposit matures and how much it will be worth on that date. Enter your deposit, rate or APY, term, and start date to see your exact maturity date and your final balance. Knowing both figures helps you plan around the grace period and avoid an unwanted automatic renewal.
How to Use the CD Maturity Calculator
Enter your initial deposit and the rate or APY your bank offers. Add the term in months or years, then enter the date you opened and funded the CD. The calculator returns your maturity date and your maturity value, which is your deposit plus all interest earned.
Use the maturity date to set a reminder before the grace period closes. Use the maturity value to compare renewal against moving your money elsewhere.
What Is CD Maturity?
CD maturity is the date your certificate of deposit reaches the end of its agreed term. On this date, your money unlocks and you can access both your principal and the interest earned without any penalty. Before maturity, withdrawing usually triggers an early withdrawal penalty.
Your maturity date depends on your start date and term. For example, a 12-month CD opened on January 15, 2026 matures on January 15, 2027. Your bank normally sends a notice as the maturity date approaches.
What Is Your CD Maturity Value?
Your maturity value is your original deposit plus all the interest it earned over the term. It is the total amount available to you when the CD matures, whether you withdraw it, renew it, or move it. A $10,000 deposit at a 4.00% APY for one year has a maturity value of $10,400.
The value grows with a higher rate, a larger deposit, or a longer term. For a full breakdown of how the interest itself is calculated, use our CD interest calculator.
What Happens When a CD Matures?
When a CD matures, you enter a short decision window called the grace period, then you choose what to do with the money. You have several clear options, and the right one depends on when you next need the funds and the rates available.
Renew at the same bank
Roll the balance into a new CD, often at the same term but at the current rate.
Move to a new CD elsewhere
Shop for a better rate at another bank or credit union and open a new CD there.
Move to a savings or checking account
Keep the money liquid while you decide your next step.
Add funds and renew
Many banks let you add money during the grace period before the CD rolls over.
What Is a CD Grace Period?
A CD grace period is the short window after maturity when you can make changes without paying a penalty. It typically lasts 7 to 10 days, though the exact length varies by bank and term. Many banks use a 10-day window for standard terms.
During this window you can withdraw, renew, change the term, or move your money. It is the one time outside of maturity itself when you can act on the CD freely. Confirm your bank's grace period policy in advance so you know your deadline.
What Happens If You Miss the Grace Period?
If you take no action during the grace period, most banks automatically renew the CD at the current rate, which may be lower than your original rate. Your money is then locked into a new term. To access it after that, you would face an early withdrawal penalty on the renewed CD.
This is the most common and costly maturity mistake. A CD that rolls over into a new term at a weak rate can quietly reduce your return for months or years. Setting a reminder a few days before the grace period ends is the simplest way to avoid it. You can estimate the cost of breaking a renewed CD with our CD early withdrawal penalty calculator.
CD Rollover and Automatic Renewal Explained
A CD rollover is when your matured CD renews into a new one, usually for the same term at whatever rate is in effect on the maturity date. If you do nothing during the grace period, most banks roll the CD over by default. The new rate could be higher or lower than what you earned before.
Automatic renewal is convenient, but it is not always in your favor. If current rates are lower, or if you will need the money soon, a rollover can lock you into a poor position. Review the renewal terms and the offered rate before letting a CD roll over.
Frequently Asked Questions
When a CD matures, your money unlocks and a grace period begins, typically 7 to 10 days. During this window you can withdraw your principal and interest penalty-free, renew the CD, move it to a different bank, or shift it to a savings account. If you do nothing, most banks automatically renew the CD at the current rate. Act within the grace period to keep full control of your funds.
A CD grace period is usually 7 to 10 days after the maturity date, though it varies by bank and term. Many banks use a 10-day window for standard CD terms, while some use a shorter period. During this time you can withdraw or change the CD without a penalty. Always confirm your bank's specific policy so you know your exact deadline.
Yes, most CDs automatically renew if you take no action during the grace period. The bank rolls your balance into a new CD, usually for the same term at the rate in effect on the maturity date. That new rate may be lower than your original one. To avoid an unwanted renewal, give the bank instructions before the grace period ends.
Yes, you can withdraw your full principal and earned interest penalty-free at maturity and during the grace period that follows. This is the one guaranteed penalty-free access point for a standard CD. Outside of that window, withdrawing early triggers a penalty. Note your maturity and grace period dates so you can withdraw on time if that is your plan.
The maturity date is when your CD term ends and your money becomes available. The maturity value is how much you receive on that date, which is your deposit plus all interest earned. For example, a $10,000 CD at a 4.00% APY for one year has a maturity date one year after funding and a maturity value of $10,400. The calculator above shows both figures at once.
Many banks let you add funds during the grace period, just before the CD renews into a new term. This is one of the few times you can increase a CD's balance, since standard CDs do not accept deposits after opening. Policies vary, so confirm with your bank whether additional deposits are allowed at renewal. If they are, the grace period is the time to do it.
