Add-On CD Defined
An add-on CD is a type of certificate of deposit usually that allows multiple deposits throughout its term, unlike traditional CDs that typically require a single lump sum at the time of opening. This flexibility enables savers to continue contributing to their CD even after the initial deposit, creating opportunities for incremental growth.
Add-On CD Key Considerations:
Interest Rates: Add-on CDs feature fixed interest rates that apply to all subsequent deposits.
Deposit Flexibility: Continuous deposits make add-on CDs practical for savers who plan to add funds regularly.
Market Rate Protection: Add-on CDs can protect against declining market rates but may not benefit from rising rates.
The Perfect Add-On CD:
Low minimum opening deposit
Unlimited deposits in any amount at any time during the term
No balance cap on additional deposits
Multi-year term of at least 2 years
Competitive rate when compared to regular CDs of the same term length
