Deposits. Deposits increased $4.5 million, or 8.0%, to $61.0 million at December 31, 2021 from $56.4 million at December 31, 2020. Savings accounts and money market accounts increased $1.3 million, or 45.0%, to $4.1 million at December 31, 2021 from $2.9 million at December 31, 2020. Certificates of deposit increased $3.3 million, or 6.1%, to $56.8 million at December 31, 2021 from $53.6 million at December 31, 2020. The increase in certificates of deposit resulted primarily from an increase in certificates of deposit derived from an online service of $3.2 million, from brokers of $1.9 million and from local retail depositors, offset in part by a decrease of $1.2 million of certificates of deposit from municipalities. Depending on market conditions, at times we have utilized non-retail funding sources to fund our loan origination and growth and to replace Federal Home Loan Bank advances, as well as in order to get longer-term funding not always available in the local market in to help reduce interest rate risk.
Certificates of deposit that are scheduled to mature in less than one year from December 31, 2021 total $18.8 million at December 31, 2021. Management expects that a substantial portion of the maturing certificates of deposit will be renewed. However, if a substantial portion of these deposits is not retained, we may utilize FHLB advances or raise interest rates on deposits to attract new accounts, which may result in higher levels of interest expense.
Borrowings. Borrowings, consisting entirely of Federal Home Loan Bank advances, decreased $1.2 million or 6.3% to $18.2 million at December 31, 2021 from $19.4 million at December 31 2020 due to maturities not renewed.
Total Equity. Total equity decreased $94,000, or 0.4%, to $21.8 million at December 31, 2021 from $21.9 million at December 31, 2020. The decrease resulted primarily from the repurchase of 22,500 shares of the Company’s common stock during the year offset, in part, by the net income of $146,000 in 2021.
