Dr. White specializes in banking sector financial stability and regulatory economics, providing expert analysis on bank liquidity and risk metrics like the Loan-to-Deposit Ratio.
The **Loan-to-Deposit Ratio Calculator** is a banking metric that assesses a bank’s liquidity and risk by comparing its total loan portfolio to its total deposits. Enter any three values—Total Loans, Total Deposits, Required Reserves, or the LDR Ratio—to solve for the missing fourth item.

*Enter any 3 values to solve for the 4th. Reserves are typically excluded from core LDR calculation but are included here for four-variable setup.
Loan-to-Deposit Ratio Formula
The core LDR Ratio is based on Total Loans and Total Deposits:
$$ LDR = \frac{\text{Total Loans}}{\text{Total Deposits}} \times 100\% $$
This metric primarily measures liquidity. The presence of Reserves is often an auxiliary balance metric, but the core formulas are:
To solve for Total Loans ($L$):
$$ L = \frac{LDR}{100} \times D_{total} $$
To solve for Total Deposits ($D_{total}$):
$$ D_{total} = \frac{L}{LDR} \times 100 $$

Variables Explained
- Total Loans ($L$): The entire loan portfolio extended by the bank. (F in input map)
- Total Deposits ($D_{total}$): The total funds deposited by customers, serving as the primary funding source for loans. (P in input map)
- Total Reserves ($R$): The cash held by the bank (or at the central bank) to meet withdrawal demands and regulatory requirements. (V in input map – *Auxiliary to LDR*)

What is the Loan-to-Deposit (LDR) Ratio?
The **Loan-to-Deposit Ratio (LDR)** is a fundamental metric in banking used to assess a bank’s liquidity risk. It measures the amount of loans a bank has extended relative to the amount of funding it has received from its core deposit base. Essentially, it tells supervisors and investors how much of a bank’s funds are tied up in loans versus how much is immediately accessible.
An LDR below 100% (or 1.0) means the bank has enough deposits to cover all its loans. A very low LDR (e.g., 50%) suggests the bank is holding too much cash and not generating optimal income through lending. A very high LDR (e.g., 120%) indicates the bank is relying heavily on potentially unstable sources of funds (like wholesale borrowing) to finance its loan book, signaling higher liquidity risk.
Regulators typically look for an LDR in the sweet spot, often considered to be between 80% and 90%, which indicates a balanced approach to maximizing lending profits while maintaining sufficient liquidity buffers to handle normal deposit withdrawals. Our calculator focuses on the primary LDR relationship, using Loans and Deposits.
How to Calculate Loan-to-Deposit Ratio (Example)
Scenario: A bank has \$80,000,000 in Total Loans and \$100,000,000 in Total Deposits.
- Identify Variables:
Total Loans ($L$): \$80,000,000
Total Deposits ($D_{total}$): \$100,000,000
- Apply the Formula (Solve for LDR):
LDR = $(\text{Total Loans} / \text{Total Deposits}) \times 100$
Calculation: $(\$80,000,000 / \$100,000,000) \times 100 = 80\%$.
- Conclusion:
The **Loan-to-Deposit Ratio** is **80%**, indicating a healthy balance between lending and liquidity.
Frequently Asked Questions (FAQ)
A ratio between 80% and 90% is generally considered optimal, indicating the bank is profitable through lending while maintaining adequate liquidity. Ratios above 100% suggest increased reliance on external funding and higher risk.
Q: How does the LDR relate to loan pricing?When a bank’s LDR is high, it signals lower liquidity, which may prompt the bank to offer higher deposit rates to attract funds or increase loan rates to slow lending and restore balance.
Q: Are Total Reserves included in the LDR calculation?No. Total Reserves are distinct from the loan and deposit figures and primarily relate to regulatory requirements. The core LDR metric focuses exclusively on the ratio of loans to customer deposits.
Q: What happens if the LDR is very low?A very low LDR (e.g., below 60%) means the bank is holding too much non-interest-earning cash, likely impacting its overall profitability. It may signal a need to increase lending activities.
