How to Do Simplex Method on a Calculator (Complete Tutorial)

If you’ve ever asked “how to do simplex method on calculator?”, this tutorial walks you through the entire process — from typing the problem to reading the optimal solution.

Step 1: Identify your LP

Write down the objective function and constraints. Decide whether you’re maximizing or minimizing.

Step 2: Enter the data

Most online simplex calculators have three input areas:

1. Objective function coefficients
2. Constraint matrix
3. RHS values

Step 3: Press Solve

The calculator outputs the initial tableau, every pivot iteration, and the final optimal solution.

Tip: For minimization problems, you can either minimize directly or convert it to maximization of the negative objective.
