How to Calculate Money Supply
To accurately calculate the money supply, one must understand the components and formulae associated with different monetary aggregates such as M1, M2, and M3. This calculation is crucial for evaluating economic policies and financial stability.
Understanding Monetary Aggregates
M1, M2, and M3 are the key monetary aggregates used to measure the money supply, as defined by the Federal Reserve. M1 includes currency in circulation and liquid deposits, making it a narrow measure of money as a medium of exchange. M2 includes all components of M1 plus savings deposits and small time deposits, representing a broader measure as a store of value. M3 includes all of M2 plus larger liquid assets, serving as the broadest measure.
Required Data for Calculation
The essential data for calculating money supply includes:- M0 (monetary base)- Currency to Deposit ratio (C/D)- Reserve ratio (rr)- Excess reserves (ER)These factors determine the supply of money through their influence on how much banks can lend.
Calculating M1 and M2
The money supply can be calculated using simple or sophisticated money multipliers. For M1, the calculation formula is generally expressed as m1 = 1 + (C/D)/[rr + (ER/D) + (C/D)]. For M2, which includes additional components like small time deposits and retail money market accounts, the formula adjusts to m2 = 1 + (C/D) + (T/D) + (MMF/D)/[rr + (ER/D) + (C/D)].
Factors Influencing Money Supply Calculation
Several factors influence the calculation of money supply. These include the currency deposit ratio (C/D), which indicates the proportion of money held in cash by the public versus deposited in banks. Another crucial factor is the reserve ratio (rr), mandated by central banks, dictating the minimum reserves a bank must hold against deposits. Excess reserves (ER) represent additional funds that banks can lend, beyond the minimum reserve requirements.
Understanding these components and their interrelationships allows for an accurate calculation of the money supply, which is pivotal in assessing economic conditions and guiding monetary policy decisions.
How to Calculate Money Supply
Understanding the Basic Components
The money supply calculation starts with understanding its components: the monetary base (MB) and the money multiplier (m). The monetary base includes all currency in circulation and reserves held by banks. The money multiplier reflects how deposits can multiply within the banking system and is influenced by the reserve requirements set by central banks.
Monetary Base (MB)
To calculate the Monetary Base, add all cash in circulation to the reserves held by banks at the Federal Reserve. This value forms the foundation of the money supply.
Money Multiplier (m)
The Money Multiplier formula, m = 1/(rr), where "rr" is the required reserve ratio, allows you to understand the extent to which an increase in the monetary base can be amplified in the banking system. For more nuanced calculations, factors such as currency held by the public versus deposits, and excess reserves need consideration. In M1, the formula adjusts to m1 = 1 + (C/D)/[rr + (ER/D) + (C/D)]. For M2 calculations, it expands to include time deposits and money market funds, expressed as m2 = 1 + (C/D) + (T/D) + (MMF/D)/[rr + (ER/D) + (C/D)].
Calculating M1 and M2
M1 is calculated by adding the total currency in circulation to checkable deposits and other liquid deposits excluding those held by the government and foreign banks. For M2, which includes all of M1 plus savings accounts, time deposits, and retail money market funds, use the expanded money multiplier m2.
Final Calculation
With the values for MB and m determined, compute the total money supply (MS) using the formula MS = m * MB. This will give you the complete view of the money supply within the economy, tailored to the levels M1 or M2, depending on the multiplier used.
Each calculation step is crucial for accurate financial analysis and policy making, reflecting the total amount of monetary assets available in the economy. Understanding both M1 and M2 provides a comprehensive scope of the liquid and near-liquid assets in circulation.

Examples of Calculating Money Supply
Example 1: Simple Sum of Currency and Deposits
To calculate the basic money supply (M1), add the total currency in circulation and checkable deposits. If the total currency circulating is $500 billion and checkable deposits are $700 billion, then M1 is M1 = $500 billion + $700 billion = $1,200 billion.
Example 2: Including Savings Deposits
M2 money supply calculation includes all of M1 plus savings deposits and small time deposits. Assuming M1 is $1,200 billion, savings deposits are $900 billion, while small time deposits total $300 billion. The M2 is calculated as M2 = $1,200 billion + $900 billion + $300 billion = $2,400 billion.
Example 3: Incorporating Money Market Funds
For a broader measure (M3), add large time deposits, institutional money market funds, and other larger liquid assets to M2. If M2 is $2,400 billion, large time deposits are $400 billion, and money market funds total $200 billion, M3 is determined by M3 = $2,400 billion + $400 billion + $200 billion = $3,000 billion.

Use Cases Unlocked by Knowing How to Calculate Money Supply
Monetary Policy Formulation |
Monetary authorities use the money supply calculations to adjust policies. By understanding the impacts of changes in the cash reserve ratio, policy makers can manipulate interest rates and control inflation, thereby stabilizing the economy. |
Impact Analysis on Economic Activities |
Analysis of money supply helps in gauging the health and weaknesses of an economy. By calculating the potential changes in money supply using the money supply multiplier (1 / Reserve Ratio), economists can predict the effects on consumption, investment, and overall economic growth. |
Inflation Control |
Excess money in the economy can lead to inflation. Calculating the money supply allows banks and regulators to set appropriate reserve ratios to control the amount banks can lend. This helps in maintaining price stability. |
Investment and Spending Simulation |
An increase in money supply reduces interest rates, spurring investments and consumer spending. Economists use money supply calculations to forecast the economic impact of lower interest rates on business expansion and employment rates. |
Crisis Management and Economic Recovery |
In times of economic downturn, calculating money supply aids in implementing quantitative easing and other fiscal measures to inject liquidity into the market. This is critical for recovery and stabilizing the financial system. |
Banking Sector Stability |
Banks must adhere to reserve requirements to ensure liquidity and solvency. Understanding and calculating money supply helps banks manage their reserves efficiently, preventing potential bank runs and financial crises. |
Risk Assessment for Lending |
With accurate money supply calculations, banks can better assess the risk associated with lending by determining how much to hold in reserve and how much can be safely loaned out to businesses and consumers. |
Frequently Asked Questions
What is the formula for calculating the money supply?
The basic formula for calculating the money supply is MS = (MB x MM), where MB is the monetary base and MM is the money multiplier.
How is M1 money supply calculated?
M1 is calculated by summing all currency in circulation, demand deposits, and other checkable deposits. Post-May 2020, M1 also includes savings accounts due to their increased liquidity.
What factors affect the money supply?
Factors affecting the money supply include changes in the monetary base, the money multiplier, and the reserve ratios set by the Federal Reserve. Adjustments in these components can change the amount of money in circulation.
How does the reserve ratio affect the money supply calculation?
The reserve ratio affects the money supply by determining the money multiplier (MM), which is calculated as MM = 1/RR, where RR is the reserve ratio. A lower reserve ratio leads to a higher money multiplier, thus increasing the potential money supply.
What is the difference between M1, M2, and M3 money supply?
M1 includes currency in circulation plus checkable deposits. M2 adds to M1 with savings accounts, time deposits, and money market accounts. M3 expands on M2 by adding long-term investments. Each level progressively includes broader and less liquid components of the money supply.
Conclusion
Understanding how to calculate the money supply is essential for analyzing economic health and making informed financial decisions. Using the formula M1 = currency + demand deposits + other checkable deposits, you can compute the narrow money supply. For a broader perspective, include savings accounts, time deposits, and money market funds in your calculation, represented by M2 = M1 + savings accounts + time deposits less than $100,000 + money market funds for individuals.
