In order to solve numerically the constant elasticity of variance (CEV) model for pricing of European call option, we propose in this work the Stochastic Runge-Kutta method. We compare the obtained results using this approache, with those given by the Monte Carlo method in Broadie-Kaya [4]. Further, we demonstrate the faster convergence rate of the error obtained by the proposed method. Finally a comparative numerical study is done using different values of the coefficient of elasticity
