A retail certificate of deposit (CD) locks a rate and a term. Breaking it early usually triggers an early-withdrawal penalty (often a set number of days of interest). Sometimes the cash need or a much higher reinvestment rate makes the penalty the cheaper path. Sometimes waiting or borrowing less expensively wins. Start with how CDs differ from liquid savings: CDs vs high-yield savings.
What is the early-withdrawal penalty, in practice?
Ask the issuer (or read the CD disclosure) for:
- Penalty formula (e.g. 90 days of simple interest, 180 days, or all interest earned on short CDs).
- Whether principal can be reduced below the original deposit if rates were low and the term short.
- Partial withdrawal rules (some banks allow a slice; many require a full break).
Brokered CDs bought on a brokerage often cannot be “broken” at the bank the same way; you may need to sell on the secondary market at a price that can be above or below face: Brokered CDs vs bank CDs.
Penalty vs reinvest math (worked sketch)
Sam holds a $10,000, 24-month bank CD at 3.00% APY with 12 months left. The bank’s early-withdrawal penalty is 180 days of interest.
- Approximate interest for 180 days: $10,000 × 0.03 × (180/365) ≈ $148.
- Sam can move the ~$9,852 net into a new 12-month CD at 4.50% APY.
Interest if Sam waits 12 months on the old CD: about $300.
Interest on ~$9,852 at 4.50% for 12 months: about $443.
Net after paying the ~$148 penalty: about $295 of interest on the new path in year one, roughly flat with waiting, before taxes and compounding details.
If the new rate were 5.50%, the same sketch yields about $542 pretax interest on the redeployed balance, which clears the penalty by a wider margin. Run your disclosure numbers; do not use this sketch as a quote.
When breaking early is often reasonable
- True emergency and no liquid emergency fund left: Emergency fund basics. Prefer breaking a CD over a 22% APR card when the penalty is a few months of interest.
- Rate reinvestment where the new locked rate clearly beats the remaining term after the penalty (use the math above).
- Better use of cash with a dated bill (taxes, deductible medical) larger than the penalty.
When waiting (or a different tool) is usually better
- You still have HYSA cash that covers the need.
- The CD matures in under ~3 months and the penalty eats most of the remaining interest.
- The CD is brokered and a secondary-market sale would price worse than the bank penalty on a retail CD: Brokered CD call risk basics.
- Deposit insurance placement is the only issue; ownership categories may solve it without a break: FDIC/NCUA insurance in practice.
Checklist before you call the bank
- Write principal, APY, maturity date, and penalty line from the disclosure.
- Get today’s competing CD or Treasury bill yield for the remaining term.
- Subtract penalty from principal; project interest on the new vehicle.
- Confirm tax year of any interest forfeited or paid (ask the issuer how 1099-INT will look).
- If it is a true cash crunch, compare the penalty to a personal-loan APR before you decide.
