CASA in banking refers to the combined value of current and savings account deposits maintained by customers with a bank. These accounts help banks maintain stable, low-cost funds while allowing customers to manage everyday banking and savings needs conveniently.
In this guide, we will explain how CASA works, how the CASA ratio is calculated, and why it matters for banks and customers.
What Is CASA in Banking?
CASA stands for Current Account and Savings Account. It refers to the combined deposits held by banks in customers' current and savings accounts. CASA helps banks maintain low-cost funds while giving customers access to everyday banking and savings facilities.
How Does CASA Work?
CASA works through two types of accounts maintained with a bank: savings accounts and current accounts.
Customers deposit money into these accounts and use them for everyday banking activities such as salary credits, bill payments, UPI transfers, withdrawals, and business transactions.
Savings accounts generally earn a small amount of interest, while the current account portion usually does not provide interest but supports frequent and high-volume transactions.
CASA Ratio: Formula & Simple Calculation
The CASA ratio in banking measures the proportion of a bank's total deposits that come from current and savings accounts.
The formula is:
CASA Ratio = CASA Deposits ÷ Total Deposits × 100
For example:
If a bank has CASA deposits worth ₹5,000 crore and total deposits of ₹10,000 crore:
CASA Ratio = (5,000 ÷ 10,000) × 100 = 50%
This means 50% of the bank's deposits come from low-cost CASA funds.
Why Does the CASA Ratio Matter to Banks?
The CASA ratio helps banks understand how much low-cost funding they have available.
A higher CASA ratio usually means banks rely less on expensive borrowing and high-interest deposits. This can improve profitability and provide banks with more flexibility in offering loans and financial products.
Banks with strong CASA ratios are often considered financially stronger because they have a stable source of funds.
