How to Calculate M2 Money Supply

M2 money supply is a key economic indicator that measures the total amount of money in circulation, including cash, checking deposits, and small-time deposits. Understanding how to calculate M2 helps economists, investors, and policymakers analyze monetary conditions and economic trends.

What is M2 Money Supply?

M2 money supply is a broader measure of the money supply than M1, which only includes physical currency and checking deposits. M2 includes all M1 components plus savings deposits, money market mutual funds, and other time deposits with maturities up to 100 days.

The Federal Reserve calculates M2 monthly and publishes it in the H.6 Report. This measure helps economists assess the liquidity of the economy and the potential for inflation or deflation.

Components of M2 Money Supply

M2 money supply consists of several components:

M1 Money Supply: Physical currency (M0) plus checking deposits (M1)
Savings Deposits: Time deposits with maturities up to 100 days
Money Market Mutual Funds: Short-term investment funds
Small Denomination Time Deposits: Time deposits with balances under $100,000

Note

The exact components may vary slightly depending on the country and the specific definition used by the central bank.

How to Calculate M2 Money Supply

To calculate M2 money supply, you need to sum the following components:

M2 Money Supply Formula

M2 = M1 + Savings Deposits + Money Market Mutual Funds + Small Denomination Time Deposits

Where:

M1 includes currency in circulation and checking deposits
Savings Deposits are time deposits with maturities up to 100 days
Money Market Mutual Funds are short-term investment funds
Small Denomination Time Deposits are time deposits with balances under $100,000

The calculation requires data from the central bank or financial institutions, as these components are typically reported separately.

Example Calculation

Let's calculate M2 money supply using hypothetical data:

Component	Amount (in billions)
M1 Money Supply	$2,500
Savings Deposits	$1,200
Money Market Mutual Funds	$800
Small Denomination Time Deposits	$400
Total M2 Money Supply	$4,900

In this example, M2 money supply is calculated as $4,900 billion by summing all components.
