Why the Maturity Date Matters
A CD's maturity date is the day your funds unlock. What many savers miss is the grace period — typically 7 to 10 calendar days after maturity — which is your only penalty-free window to withdraw the money, add funds, or move to a different term. If you do nothing, most banks automatically renew the CD for the same term at whatever the current rate is, which is often much lower than promotional rates.
How to Use This Calculator
Enter your opening date and the term in months. The calculator gives the exact maturity date and counts down the days remaining. Put a reminder in your phone for a few days before maturity so you can shop rates before the grace period starts.
Pro Tip
Banks rarely renew you into their best rate. When your CD matures, compare current offers — moving your money at maturity is free, and even 0.5% more APY on a large deposit is real money.
