# 45 Day Supply Calculator

Managing inventory or planning medication refills often involves ensuring you have enough supply for a given period. For instance, knowing how much stock you need for a 45-day period can help in efficient resource management and avoid shortages. This 45-Day Supply Calculator helps you determine how much supply is needed over a 45-day period based on the quantity and daily usage.

### Formula

To calculate the 45-day supply, multiply the quantity by daily usage and then divide by 45. This will give you the required supply for a 45-day period.

### How to Use

Using the 45-Day Supply Calculator is simple:

- Enter the quantity (Q) in the first input field.
- Enter the daily usage (D) in the second input field.
- Click the “Calculate” button to see the 45-day supply.
- The result will be displayed in the designated output field.

### Example

For example, if you have a quantity of 900 units and your daily usage is 20 units, the 45-day supply would be calculated as:

- Multiply the quantity by the daily usage: 900 * 20 = 18,000.
- Divide by 45: 18,000 / 45 = 400.

So, you would need a supply of 400 units for a 45-day period.
