The Credit Builder Account is a CD-Secured Installment Loan. The account can be closed at anytime. If you choose to close your account early the CD will be liquidated to repay the remaining balance of the loan. 

However, please be aware that payment history is the most important factor in determining your credit score. By paying off your account early, you may not be able to establish 12-months or 24-months of payment history with the credit bureaus. Your completed loan would be reported as if you’ve paid off the account early and any information reported during the life of the loan will remain on your report. 

Closing early could then limit the potential benefit of building payment history to your credit score, and your score could fluctuate. 

If you decide to close the account prior to maturity, you may also be charged an early withdrawal fee and your payout will be less unpaid fee's and interest.
