The formula to calculate the excess reserves is:
\[ \text{ER} = \text{LR} - \text{RR} \]
Where:
Excess reserves refer to the amount of reserves that a bank holds over and above the required reserves. These are typically held at the central bank and represent the extra liquidity that the bank has available for lending or other purposes.
Let's consider an example:
Using the formula to calculate the excess reserves:
\[ \text{ER} = 5,000,000 - 3,500,000 = 1,500,000 \text{ dollars} \]
This means that the bank has excess reserves of $1,500,000.
