Loan Margin Calculator
In the financial sector, lenders and financial institutions strive to maximize profitability while managing risk. A crucial metric for evaluating profitability on loans is the Loan Margin — the difference between the interest rate charged to borrowers and the lender’s cost of funds.
The Loan Margin Calculator is a practical tool that helps banks, credit unions, and other lenders quickly compute their loan margin percentage. This insight enables smarter pricing of loan products, improved risk management, and better financial decision-making.
What Is Loan Margin?
Loan margin refers to the difference between the interest rate a lender charges a borrower and the lender’s own cost of funds, expressed as a percentage. It reflects the gross profit margin on a loan before deducting operational costs and loan losses.
A positive loan margin means the lender earns more on the loan than it costs to fund it, while a negative margin signals a potential loss.
Formula
The formula to calculate loan margin is:
Loan Margin (%) = Interest Rate (%) – Cost of Funds (%)
Where:
- Interest Rate is the annual percentage rate charged to the borrower.
- Cost of Funds is the effective interest rate the lender pays to raise capital (e.g., deposit interest, borrowing costs).
How to Use the Loan Margin Calculator
- Enter the Loan Amount you are evaluating (for reference).
- Enter the Interest Rate you charge the borrower (annual percentage).
- Enter your Cost of Funds, or the rate you pay to acquire the loan capital.
- Click Calculate to see your loan margin in percentage terms.
This calculation quickly reveals how much gross profit you earn on each loan, helping you adjust pricing or risk appetite.
Example
Suppose a bank lends $100,000 at an interest rate of 8% per year, and its cost of funds is 5%.
Loan Margin = 8% – 5% = 3%
This means the bank earns a 3% gross margin annually on the loan before other expenses.
