Use this partition calculator to accurately divide a set of items into equal parts.

## How to Use the Partition Calculator

This partition calculator helps you determine the number of fixed-size partitions that can fit into a total size, taking into account any overhead (such as filesystem overhead) that affects the usable space.

### Instructions:

- Enter the Total Size in the first input field.
- Enter the Partition Size in the second input field.
- Enter the Overhead percentage in the third input field.
- Click the “Calculate” button to get the result.

### How It Calculates the Results:

The calculator performs the following steps:

- Divides the Total Size by the Partition Size to determine the maximum number of partitions.
- Calculates the overhead per partition by taking the specified percentage of the Partition Size.
- Multiplies the number of partitions by the overhead per partition to get the total overhead.
- Subtracts the total overhead from the Total Size to determine the usable size.

The result is displayed as the number of partitions and the usable size after accounting for the overhead.

### Limitations:

- The calculator assumes uniform partition sizes and overhead percentages.
- It does not take into account any other factors that may affect storage utilization, such as reserved space or fragmentation.
- Ensure that inputs are valid numbers to get accurate results.

By following these instructions, you’ll be able to efficiently calculate the partition layout for your storage requirements.

## Use Cases for This Calculator

### Calculate the Total Number of Partitions

Enter the total number of items you want to partition and let the calculator determine all possible ways to partition them into smaller groups or subsets.

### Determine the Number of Ways to Partition into Equal Groups

Specify the total items and the size of each group you want, and instantly find out how many ways you can partition the items into equal-sized groups.

### Find the Number of Unique Partitions

Input the total items, and discover how many unique ways you can partition them into different groups, including all permutations and combinations.

### Calculate the Number of Overlapping Partitions

Enter the total items and the size of overlapping groups, and find out the number of ways you can partition the items with overlaps considered.

### Determine Partitions with Constraints

Set specific constraints such as maximum group size or total number of groups, and quickly calculate the number of valid partitions meeting those conditions.

### Find Partitions with Exclusions

Select certain elements to be excluded from specific groups, and see the number of partitions that can be created without those exclusions.

### Calculate Partitions with Fixed Elements

Specify certain elements that must be together in a group, and determine the total number of partitions with those fixed elements grouped accordingly.

### Determine Partitions with Unordered Groups

If the order of groups doesn’t matter, input the total items and group sizes to calculate the number of unique partitions with unordered groups.

### Find Partitions with Repeated Items

If you have repeated items and want to partition them in various ways, enter the repeated items along with the total count to discover all possible partitions.

### Calculate Partitions with Weighted Items

Assign weights to your items and specify a total weight to partition, then find out how many ways you can partition the items respecting their assigned weights.
