Inverse Matrix Calculator
Inverse Matrix Calculator is a browser-based calculator tool on CalcToolsBase. Free, browser-based Inverse Matrix Calculator with instant, clearly-labelled results. No signup, no uploads. To use it, enter your values and view the result directly in your browser — no signup and nothing to install.
Inverse Matrix Calculator lets you work through a calculation in seconds: enter your matrix for the result, all worked out locally in your browser.
About this calculator
The Inverse Matrix Calculator gives you a quick way to work through a calculation. Enter your matrix; it then returns the result, worked out with the standard method the moment you calculate. It runs fully in the browser, so it is private by design and works offline once loaded.
Made for students and anyone checking their working, it gives the result from your matrix in one step — clearly laid out, free to use, and computed entirely on your device.
How to use
- Type a square matrix to invert, with rows separated by semicolons or new lines and values by commas.
- For example, enter 4, 7; 2, 6 for a 2 by 2 matrix.
- Press Calculate to compute the inverse.
- Read the inverse matrix and the determinant used to find it.

Technical notes
Inverse Matrix Calculator computes the inverse as adj(A) ÷ det(A), and flags a singular matrix when det = 0.
Inputs are taken exactly as entered, so check for typos before trusting an answer.
Because it runs locally, results appear instantly with no server round-trip.
FAQ
Which matrices have no inverse?
A matrix has no inverse when its determinant is zero, meaning it is singular. The calculator detects this and reports it instead of returning numbers.
How large a matrix can I invert?
The inverse calculator supports square matrices up to 8 by 8. Larger matrices are rejected with a message.
How do I format the rows?
Separate values with commas or spaces and rows with a semicolon or a new line, for example 4, 7; 2, 6.
Does the Inverse Matrix Calculator send my data to a server?
No. The Inverse Matrix Calculator runs entirely in your browser, so nothing you enter is uploaded, stored, or shared.
Worked example
For [[4,7],[2,6]] (det 10), the inverse is (1/10)×[[6,−7],[−2,4]] = [[0.6,−0.7],[−0.2,0.4]].
