The Canadians’ Preparation for Retirement (CPR) project aims to shed light on the risks that may impact future pension plan adequacy of Canadians in a rapidly changing pension landscape. To answer this question, the research team developed an open-access stochastic retirement preparation simulator based on transparent and flexible assumptions. The individual online interface of the CPR simulator is now available. The calculator includes a stochastic version that models fluctuations over time for several variables such as investment returns, house prices, earnings, etc. Importantly and innovatively, this allows to compute not only retirement preparedness in a binary manner, but also the probability that a household will be adequately prepared for retirement.
