FAQs
The Kingdom Builder Account enables you to earn an exceptional above market rate while also supporting your ministry’s cause of choice. Your return will be the featured rate on this landing page. At the end of each month, AdelFi will make an additional donation to your ministry’s cause based upon the collective funds in the Kingdom Builder Savings account from all church/ministry members that is above and beyond the earnings you make on your individual account. In other words, the more collective deposits in the Kingdom Builder Savings account, the more funds get donated for your church/ministry’s cause.
There is no limit to your investment. Upon initial opening of the account, there is a $100 minimum to open and an initial deposit maximum of $52,500. Additional deposits can be made after account opening with no limits.
The rate for the Kingdom Builder Savings Account is not locked and is subject to change. AdelFi will always strive to provide the most competitive rates possible.
