Add On CDs: Which Banks/CUs Offer Them?

I learned about Add On CDs last year. They are a product where the customer can add additional funds to the CD, at any time, either limited or unlimited, and get the original rate of the CD. This is fantastic for a decreasing interest rate environment, like the kind we are currently in.

NFCU is the place where I learned about this. Are there any other banks or credit unions that the group knows of that offers this?

I know of 3 off the top of my head but I’m sure there are many more.

Bank5Connect has a 24 month investment CD that allows for add ons. The interest rate is average to below average at just 2.10%.

Mountain America Credit Union allows any of their CD’s to be opened as add on CD’s. Their current interest rates are also average to below average although I think their 60 month 2.3% CD is a decent hedge against lower rates as you can open with as low as $5. It does, however, require at least a $10 monthly deposit.

PSECU CD’s have a non-traditional add on capability in that you must set up re-occurring monthly transfers to add on to the CD on a regular basis. You cannot increase the amount of the re-occurring transfer to the CD but can decrease or stop at anytime. Rates are solidly below average at this time however just a few months ago they had great rates for example 3.25% for a 3 year.

Note: Both credit unions have fairly easy nationwide membership requirements or at least did when I joined.


GTE Financial also offers add on cds.


I was denied membership there back when they were offering very good rates but YMMV.
