A computer program to estimate the parameter value from the complex impedance data of the equivalent circuit is reported. Non-linear complex least squares fitting is made using a laboratory microcomputer (with real values). Different values are used as the initial guess in the iterative calculation of complex least-square method which fits both real and imaginary components of the actual impedance. The program is tested for simple RC circuits which are generally used to model the electrochemical system by introducing random experimental errors and it is found to converge within a few number of iteration.
