Calculate Matrix Determinant

If you’ve got a matrix and you want to know its determinant fast, this tool makes it painless. Just type or paste your square matrix into the input, hit calculate, and bam you get the determinant on the spot. It works with any size square matrix and updates the output live. No setup, no formulas, no delay.

Paste your matrix above or import a file below.

How to Use:

  1. Paste your matrix into the input field. Use commas for columns and newlines for rows (e.g., 1,2\n3,4).
  2. The tool auto-calculates and displays the determinant on the right.
  3. Click Copy Output to copy the result.
  4. Use Export to File to download the determinant as a .txt.
  5. Hit Clear All to reset and try a new matrix.

What Matrix Determinant Tool can do:

Matrix Determinant Tool supports real-time determinant calculations for any size square matrix. It uses the math.js library to compute accurate values even for large or complex matrices. The tool checks validity automatically and returns helpful feedback if the matrix isn’t square. You don’t need any setup it runs entirely in your browser and updates live.

Example:

Input:

1,2
3,4

Output:

-2

Common Use Cases:

Perfect for linear algebra homework, quick checks in programming, or verifying a solution manually. It’s simple, clean, and always shows you the result right away no steps skipped, no fluff. Just the determinant, exactly when you need it.

Useful Tools & Suggestions:

After finding a determinant, Find Matrix Inverse is a natural next step if you’re solving systems or checking invertibility. And if you want to reorient the data, Find the Transpose of a Matrix lets you flip things around fast.
