Use this tool to calculate the determinant of a square matrix quickly and accurately.

Determinant Calculator

How to Use the Determinant Calculator:

To calculate the determinant of a 2×2 matrix, input the values for each cell in the form fields above. Each field represents an element in the matrix, with the following mapping:

  • A1,1: Top-left element
  • A1,2: Top-right element
  • A2,1: Bottom-left element
  • A2,2: Bottom-right element

Once all values are entered, click the “Calculate” button. The result will be displayed immediately in the “Result” field.

How it Calculates the Results:

The calculator computes the determinant of a 2×2 matrix using the formula:

Determinant = (A1,1 x A2,2) – (A1,2 x A2,1)

It multiplies the top-left element by the bottom-right element and subtracts the product of the top-right element and the bottom-left element.


This calculator is designed to compute the determinant of only 2×2 matrices. For larger matrices, the computation is more complex and requires a different calculator.
