1. What is Cost Of Funds (COF)?

Cost Of Funds (COF) represents the interest rate financial institutions pay to acquire funds for lending and investment activities. It measures the average interest paid on deposits and borrowings, serving as a key indicator of a bank's funding efficiency.

2. How Does the Calculator Work?

The calculator uses the COF formula:

\[ COF = \frac{\text{Interest Expense}}{\text{Average Interest-Bearing Liabilities}} \times 100 \]

Where:

\( \text{Interest Expense} \) — Total interest paid on deposits and borrowings (USD)
\( \text{Average Interest-Bearing Liabilities} \) — Average balance of interest-bearing deposits and borrowings (USD)
\( COF \) — Cost of funds expressed as a percentage (%)

Explanation: The formula calculates the effective interest rate a bank pays for its funding sources, providing insight into its cost structure and profitability.

3. Importance of COF Calculation

Details: COF is crucial for banks to determine lending rates, assess funding efficiency, monitor competitive positioning, and make strategic decisions about deposit pricing and funding mix.

4. Using the Calculator

Tips: Enter interest expense in USD, average interest-bearing liabilities in USD. Both values must be positive numbers. The result shows COF as a percentage.

5. Frequently Asked Questions (FAQ)

Q1: What constitutes interest-bearing liabilities?
A: Includes savings accounts, time deposits, certificates of deposit, money market accounts, and other borrowings that pay interest to depositors or lenders.

Q2: How does COF affect bank profitability?
A: Lower COF indicates more efficient funding, allowing for better net interest margins and higher profitability when lending rates remain constant.

Q3: What is a typical COF range for banks?
A: Varies by economic environment, but typically ranges from 0.5% to 3% for well-managed banks in stable economic conditions.

Q4: How often should COF be calculated?
A: Most banks monitor COF quarterly, but it can be calculated monthly for more frequent performance tracking and strategic adjustments.

Q5: What factors influence COF?
A: Market interest rates, competition for deposits, bank's credit rating, funding mix, and overall economic conditions significantly impact COF.
