CASA in Banking – Full Form, Meaning, Benefits and How It Works
CASA’s full form is Current Account Savings Account. It is one of the most important concepts in banking because it helps explain how banks raise funds, manage costs, and generate profits.
CASA represents the deposits held in current accounts and savings accounts. In this blog, see how the CASA ratio benefits both banks and customers.
What is CASA?
CASA (Current Account Savings Account) in banking refers to the total deposits that a bank receives through current accounts and savings accounts.
CASA is an important metric because it represents a source of low-cost funds for banks. Since current accounts generally do not earn interest and savings accounts offer comparatively lower interest rates than fixed deposits, banks can use these funds to support lending activities at a lower cost.
A strong CASA base can improve a bank’s financial health, while a higher CASA ratio is often considered a positive indicator of operational efficiency and profitability.
How Does CASA Work?
It works through CASA products, namely savings accounts and current accounts.
CASA in banking functions through the deposits that customers maintain in these accounts. Banks use these deposits as a source of funds while allowing customers easy access to their money whenever needed.
Here’s how it works:
- Customers deposit money: Individuals and businesses deposit funds into savings accounts and current accounts for their daily banking needs.
- Easy access to funds: Customers can withdraw, transfer, or use their money whenever required through branches, ATMs, internet banking, or mobile banking.

- Interest on savings accounts: Banks pay interest on savings account balances, while current accounts generally do not earn interest.
- Banks use deposits for lending: A portion of CASA deposits is used by banks to provide loans and other credit facilities to borrowers.
- Banks earn revenue: Banks charge a higher interest rate on loans than the interest paid on CASA deposits, allowing them to earn income from the difference.
- Supports banking operations: CASA deposits provide banks with a stable and relatively low-cost source of funds, helping them manage liquidity and support lending activities.
Difference Between Current Account and Savings Account
Current accounts are primarily designed for businesses that need to make frequent transactions. On the other hand, savings accounts are intended for individuals looking to save money while earning interest.
Together, these accounts form a bank’s CASA deposits and contribute to its CASA ratio.
| Feature | Current Account | Savings Account |
| Purpose | Supports frequent business transactions | Helps individuals save money |
| Interest Earned | Usually no interest | Earns interest on deposits |
| Primary Users | Businesses, traders, and companies | Individuals, students, and salaried professionals |
| Transactions | High transaction volume | Suitable for regular personal banking |
| Overdraft Facility | Often available | Generally not available |
| Main Objective | Managing day-to-day business operations | Saving and growing funds |

CASA Deposits Meaning
CASA deposits refer to the money deposited by customers in current accounts and savings accounts.
For banks, these deposits are valuable because they generally cost less than fixed deposits and recurring deposits.
For example:
| Deposit Type | Amount |
| Current Account Deposits | ₹300 Crore |
| Savings Account Deposits | ₹700 Crore |
| Total CASA Deposits | ₹1,000 Crore |
In this example, the bank’s CASA deposits amount to ₹1,000 crore.
CASA Ratio Meaning
The CASA ratio is a banking metric that measures the proportion of a bank’s total deposits that come from current accounts and savings accounts.
It is calculated using the following formula:
CASA Ratio Formula = (Current Account Deposits + Savings Account Deposits) ÷ Total Deposits × 100
For example, if a bank has ₹4,000 crore in CASA deposits and total deposits of ₹10,000 crore, its CASA ratio would be 40%.
A higher CASA ratio generally indicates that a bank has a larger share of low-cost deposits. This can help reduce funding costs, improve profitability, and strengthen the bank’s overall financial position.
CASA Ratio Example
Suppose a bank has:
- Current Account Deposits: ₹2,000 crore
- Savings Account Deposits: ₹3,000 crore
- Total Deposits: ₹10,000 crore
The CASA ratio would be:
(₹2,000 crore + ₹3,000 crore) ÷ ₹10,000 crore × 100
= 50%
This means that 50% of the bank’s total deposits come from current and savings accounts.
