1. What is the Bank Reserves Calculation?

The bank reserves calculation determines the amount of funds that a bank must hold in reserve against deposits made by their customers. This is a key requirement in fractional-reserve banking systems.

2. How Does the Calculator Work?

The calculator uses the simple reserves formula:

Where:

• \( Deposits \) — Total customer deposits in dollars
• \( Reserve\ Ratio \) — The fraction of deposits required to be held in reserve (as a decimal)

Explanation: The formula calculates the minimum amount of reserves a bank must maintain based on its deposit liabilities and the reserve requirement set by the central bank.

3. Importance of Reserve Calculation

Details: Proper reserve calculation is crucial for banks to maintain liquidity, meet withdrawal demands, and comply with regulatory requirements while maximizing their lending capacity.

4. Using the Calculator

Tips: Enter total deposits in dollars and the reserve ratio as a decimal (e.g., 0.1 for 10%). Both values must be positive, with reserve ratio between 0 and 1.
