CD Auto-Renewal Calculator: The Cost of Renewing at the Standard Rate
Promotional CD rates can be far above an institution's standard rates. If the CD renews automatically at maturity, the new term earns the standard rate. Enter both rates to see the difference.
$80.00 less
Over 1 year, $10,000 earns $370.00 at the standard 3.70% instead of $450.00 at 4.50% — $80.00 per year.

How to avoid it
Note the maturity date, and during the grace period (often 7–10 days) withdraw the money or ask for the current promotional rate. Our institution pages show both promotional and standard rates where the institution publishes them.
Questions
Do all CDs renew automatically?
Many do, but the account disclosure determines whether the CD renews and which rate and term apply. Some promotional CDs renew into a different, standard term.
Is the old promotional rate guaranteed at renewal?
No. The renewal rate can differ from the original rate. Check the maturity notice and current account terms.
How is the cost of renewal calculated?
The tool compares interest at the two APYs over the same period, assuming a fixed balance, constant rates and no withdrawals.
Does the comparison include taxes or penalties?
No. It shows the interest difference before tax and fees. Moving money outside the permitted withdrawal period may incur a penalty.
How do I check the grace period?
Read your maturity notice or ask the institution before maturity. The permitted withdrawal window and any renewal term depend on your account.
