The Company believes its deposit product offerings are properly structured to attract and retain core deposit relationships. The average cost of interest-bearing deposits for the three months ended September 30, 2024, and 2023, was 3.20% and 2.84%, respectively. The cost increase was primarily attributable to the rate increases. The average cost of interest-bearing deposits for the nine months ended September 30, 2024, and 2023, was 3.19% and 2.45%, respectively. The cost increase was primarily attributable to the increases in rates and increased pricing competition.
Total deposits as of September 30, 2024, were $4.32 billion, which was an increase of $54.6 million from December 31, 2023. This overall increase was driven primarily by the issuance of brokered deposits of $174.8 million, increase in other time deposits of $44.3 million and savings deposits of $42.4 million, offset by a decline in interest-bearing demand deposits of $172.7 million and noninterest bearing deposits of $34 million. During the quarter, the Bank elected not to pursue a higher cost public funds depository relationship and utilized Federal Home Loan Advances temporarily, which was replaced with brokered deposits. As of September 30, 2024, the Company had outstanding time deposits under $250,000 with balances of $516.9 million and time deposits over $250,000 with balances of $252.7 million.
