Simple Deposit Multiplier Formula:
| From: | To: |
The Simple Deposit Multiplier is a concept that represents the potential increase in the money supply through the process of fractional reserve banking. It shows how much the money supply can potentially increase based on the required reserve ratio.
The calculator uses the Simple Deposit Multiplier formula:
Where:
Explanation: The formula calculates the maximum potential money supply expansion through the banking system's lending activities based on the reserve requirement.
Details: Understanding the simple deposit multiplier is crucial for monetary policy analysis, banking system operations, and comprehending how fractional reserve banking affects the overall money supply in an economy.
Tips: Enter the required reserve ratio as a decimal value (e.g., 0.1 for 10%). The value must be between 0.0001 and 1.
Q1: What is the relationship between reserve ratio and money multiplier?
A: There is an inverse relationship - as the required reserve ratio increases, the money multiplier decreases, and vice versa.
Q2: Why is the simple deposit multiplier considered "simple"?
A: It's called "simple" because it assumes that all money is deposited in banks, banks lend out all excess reserves, and there are no cash leakages from the banking system.
Q3: How does this differ from the real-world money multiplier?
A: In reality, the actual money multiplier is usually smaller due to cash holdings by the public, banks holding excess reserves, and other factors not accounted for in the simple model.
Q4: What's a typical required reserve ratio?
A: Reserve requirements vary by country and bank size, but typically range from 0% to 10% of deposits in most modern banking systems.
Q5: Can the money multiplier be less than 1?
A: No, since the reserve ratio is always between 0 and 1, the money multiplier is always greater than or equal to 1.
