Advanced Complex Number Calculator with Live Argand Plane Visualization
The Complex Calculator is a powerful, interactive online tool designed to perform complex number operations with real-time graphical visualization on the Argand Plane. Whether you are a student, engineer, physics learner, or mathematics professional, this calculator helps you understand complex arithmetic both numerically and visually.
This tool supports addition, subtraction, multiplication, and division of complex numbers, along with automatic calculation of magnitude (modulus) and phase (argument). The live simulation instantly plots all inputs and results, making it one of the most intuitive complex number calculators online.
What Is a Complex Number?
A complex number is written in the form:
z = a + bi
- a → Real part
- b → Imaginary part
- i → Imaginary unit (√−1)
Complex numbers are widely used in electrical engineering, signal processing, quantum mechanics, control systems, and applied mathematics.

Mathematical Formulas Used
- Addition & Subtraction
- (a + bi) ± (c + di) = (a ± c) + (b ± d)i
- Multiplication
- (a + bi)(c + di) = (ac − bd) + (ad + bc)i
- Division
- (a + bi)/(c + di) = [(ac + bd) + (bc − ad)i] / (c² + d²)
- Magnitude
- |z| = √(a² + b²)
- Phase Angle
- θ = tan⁻¹(b / a)
