The Change in Money Supply Calculator helps in determining how changes in bank reserves affect the total money supply in an economy. This is crucial for understanding monetary policy, inflation, and banking operations.
Formula
The change in money supply is calculated as:
Change in Money Supply (ΔM) = Money Multiplier (m) × Change in Reserves (ΔR)
How to Use
- Enter the money multiplier (m), which depends on the reserve ratio.
- Input the change in reserves (ΔR), which represents the change in bank reserves.
- Click the “Calculate” button to get the change in money supply.
Example
If the money multiplier is 5 and the change in reserves is $1000, the change in money supply will be:
ΔM = 5 × 1000 = $5000
