All of us have heard about savings account and current account but none of us knows what it actually is. Well, a savings account is opened by an individual and current account by a company. The savings account receives interest while current account receives none.
CASA ratio stands for total deposits in relation to current and savings accounts. Current account and savings account ratio of a bank is the ratio of deposits in current and savings accounts compared to its total deposits. Banks do not give any interest on current account deposits and the interest on a savings account is usually very low between 3-4%.

Importance
The CASA ratio indicates how much of a bank’s total deposits are in current and savings accounts. A higher ratio means a larger portion of a bank’s total deposits are in current and savings accounts, thus indicating, lower cost of funds. Which means the higher the deposits in both of these accounts the lower will be the cost of managing the funds. Banks pay interest at 3-4% on savings deposit which is way below its lending rate thus decreasing the cost. For instance, most banks lend at over 10%, whereas, the rate of interest that they pay on savings deposits is just 3-4%.

Impact
If a large part of a bank’s deposits comes from these funds, it means that the bank is getting those funds at a relatively lower cost. It is generally understood that a higher current account and savings account ratio leads to higher net interest income because the interest paid on CASA deposits is lower than on term deposits hence the NII tends to be higher. Therefore, the higher the CASA ratio, the better the net interest margin, which means better operating efficiency of the bank. Current account and savings account deposits are a cheaper source of raising funds as compared to a certificate of deposits, term deposits which relatively requires higher interest to be paid.
How to Calculate CASA Ratio Formula
CASA Ratio (%) = CASA Deposits/Total Deposits
Explanation
Suppose a bank ABC has total deposits as Rs. 50,000 crore and savings account deposits is Rs. 15000 crores and current account deposits are Rs. 8,000 crores.
CASA Ratio (%) = (15000+8000)/50000 = 46%
Thus, the CASA ratio of the bank is 46% which means 46% of total deposits are contributed by low-cost CASA deposits.

Stockedge App
We don’t have to calculate the CASA ratio (%) with the StockEdge app. StockEdge gives us the CASA ratio of the last five years of any banks listed in the stock exchange. We can look and compare it and filter out stocks accordingly.
Suppose we want to look at CASA ratio of ICICI Bank Ltd. for last 5 years, then in the Fundamental tab of ICICI Bank Ltd., we will get Ratios tab. Then in the Ratios tab click on the Liquidity Ratios, we will get the CASA ratio (%) of ICICI Bank Ltd.
The downside of CASA (%)
For long–term financing of big Projects, Banks major focus is on term deposits as depositors may not like to withdraw the deposit before the maturity, this is because current and savings account deposits can move out of the bank’s books anytime which can lead to asset-liability mismatch. Banks can improve CASA ratio by offering a higher rate of interest on deposits which can attract more deposits, on the other hand, it will have to pay higher interest rates to the depositors.
Frequently Asked Questions
u003cstrongu003eHow is CASA ratio calculated?u003c/strongu003e
CASA Ratio (%) = (CASA Deposits/Total Deposits). Suppose a bank ABC has total deposits as Rs. 50,000 crore and savings account deposits is Rs. 15000 crores and current account deposits is Rs. 8,000 crores. CASA Ratio (%) = (15000+8000)/50000 = 46%. Thus, the CASA ratio of the bank is 46% which means 46% of total deposits are contributed by low-cost CASA deposits.
u003cstrongu003eWhy CASA ratio is important?u003c/strongu003e
A higher CASA ratio means higher portion of the deposits of the bank has come from current and savings deposit, which is generally a cheaper source of fund. Many banks don’t pay interest on the current account deposits and money lying in the savings accounts attracts a mere 3.5% interest rate. Hence, higher the CASA ratio better the net interest margin, which means better operating efficiency of the bank. Net interest margin is difference between total interest income and expenditure and is shown as a percentage of average earning assets. Higher income from CASA will improve the net interest margin as the cost of this fund is relatively lower. For instance, most banks lend at over 10%, whereas, the rate of interest that they pay on saving deposit is just 3.5%..
u003cstrongu003eHow do you increase CASA ratio?u003c/strongu003e
