This paper proposes a new multilevel Monte Carlo (MLMC) method for the ergodic SDEs which do not satisfy the contractivity condition. By introducing the change of measure technique, we simulate the path with contractivity and add the Radon–Nikodym derivative to the estimator. We can show the strong error of the path is uniformly bounded with respect to T. Moreover, the variance of the new level estimators increase linearly in T, which is a great reduction compared with the exponential increase in standard MLMC. Then the total computational cost is reduced to O (ε− 2| log ε| 2) from O (ε− 3| log ε|) of the standard Monte Carlo method. Numerical experiments support our analysis.
