What does the bank do with your money? Step 4: Finally, the formula for the fiscal multiplier can be derived as negative MPC (step 3) divided by one minus MPC as shown below. This whole process of originating loans, these deposits flowing back to the banks and banks lending out a fraction of the money again is called fractional reserve banking. The reserve requirement is 25%. So now there’s $1,900 in new deposits. The fraction of deposits they continue to hold is used to meet withdrawals by banking clients. And during a recession, both of these things can happen at the same time. Again, the banks originate loans and are required to hold a certain fraction as reserves.

You can figure that out using what’s called the “money multiplier.”. If Grandma had instead given you a check for $1,000, she’d simply be transferring money from her account to yours, which would not be creating new reserves, and so we wouldn’t see this multiplier effect. Step 3: Next, compute MPC by dividing the change in consumption (step 2) by the change in disposable income (step 1). The simple money multiplier formula is the following, The total amount of money that can be created for a given reserve requirement can also be calculated easily. We also provide a Multiplier calculator with a downloadable excel template. At the bottom of this page, we include an Excel spreadsheet that implements a money multiplier calculator.

Fiscal multiplier, on the other hand, describes the relationship between the economic output or Gross Domestic Product (GDP) of a nation and its tax regulation. That borrowed money in turn ends op on the deposit accounts of other clients. The formula for the fiscal multiplier is expressed by dividing the negative marginal propensity to consume (MPC) by marginal propensity to save (MPS). Step 2: Next, determine the change in consumption which is a proxy for personal spending. And if this is the case, the Fed will have a lot of leverage to move M1 and M2 with a small change in reserves. During 2018, the bank received total deposits of $50 million and it extended loan worth $45 million.

As an example, suppose the reserve requirement is 2%. In particular, when banks lend out money to borrowers, the banks typically lend out only a certain fraction and not the full amount of deposits their clients deposited with them. So the reserve ratio can be greater than 10% and it can change over time. The multiplier effect follows naturally from banks’ loan origination process. Suppose the central bank creates a $1000 in high-powered money. The simple money multiplier or deposit multiplier measures how much money a certain deposit can create when the banking sector engages in fractional reserve banking. And as the banks make more loans, that increases the number of deposits, which increases the number of loans, which increases the number of deposits.
