How CD early withdrawal penalties work

CD early withdrawal penalties are set by each bank and written into the account disclosures, which must say whether a penalty applies, how it is calculated and when it is charged.[2] Most are stated as days or months of interest, and longer terms usually carry larger penalties. Federal rules set only the minimum: at least seven days' simple interest on money withdrawn within six days of deposit.[1][3]

Penalty=Deposit × CD rate × penalty period

On $10,000 at 4.40% APY (about 4.306% as a rate), a 12-month penalty is about $430.62, whenever you withdraw. Some banks compute it on the amount withdrawn rather than the whole deposit, or use interest actually earned; check your agreement and enter its terms.

Can you lose money breaking a CD?

Yes. Early in the term the penalty can exceed the interest earned so far, and the difference comes out of your deposit. With a 12-month penalty on a 5-year CD at 4.40% APY:

1 month$35.95$430.62$9,605.33$394.67 below deposit

6 months$217.63$430.62$9,787.01$212.99 below deposit
12 months$440.00$430.62$10,009.38$9.38 gain

36 months$1,378.93$430.62$10,948.31$948.31 gain

Once the CD has earned more than the penalty, breaking it no longer touches principal. The SEC and the CFPB both advise checking the penalty before you buy a CD.[5][4]

Should I break my CD for a higher rate?

Break a CD only if the new rate earns back the penalty before the old CD would have matured. The calculator compares two paths for the remaining months: keep the CD, or take the payout and reinvest it at the new APY. In the example, after 18 months with 42 months left, the break-even is 5.64% APY; at 5% you end $259.54 behind by breaking.

  • The bigger the rate gap and the more time left, the more likely breaking pays.
  • Near maturity, breaking rarely pays: the penalty is fixed but little time is left to make it back.
  • Compare against the rate you can actually get for the same remaining term, not a teaser rate.

Alternatives to breakingSome CDs allow a partial withdrawal or have no penalty (no-penalty CDs). Withdrawing interest only may be penalty-free. A CD ladder keeps part of your money maturing regularly so you rarely need to break one.

Frequently asked questions

How is a CD early withdrawal penalty calculated?

Usually as a number of days or months of simple interest at the CD's rate: deposit × rate × (days ÷ 365). Your account agreement gives the exact method.

What is the typical penalty for breaking a CD?

It varies by bank and term, and longer CDs usually carry larger penalties; your account disclosure states it. The federal minimum is seven days' interest for withdrawals within six days of deposit.

Can a CD penalty take my principal?

Yes, if you withdraw before the CD has earned as much interest as the penalty. The table above shows when that stops.

Is it worth breaking a CD for a higher rate?

Only if the new rate beats the break-even rate for the time left. For the example 5-year CD broken after 18 months, that is 5.64% APY.
