The need to endow marketing graduates with skills relevant to employability grows ever more important. Marketing math and elementary financial understanding are essential employability skills, particularly given the contemporary emphasis on marketing metrics, but the evidence is that marketing graduates are often relatively weak in such skills. This article suggests that one educational strategy to improve numeracy and financial skills may be through the use of a marketing simulation game. Through the simulation game, students are exposed to marketing calculations and financial data in an engaging context that simulates the real world. It is hypothesized that marketing students' numeracy and financial skills, and their self-efficacy with respect to marketing calculations, will improve following participation in a simulation game where numerical and financial analysis are necessary activities. Using a quasi-experimental research design, it is found that there are substantial and significant improvements in numerical and financial performance after participating in a simulation game, but that there is no improvement (and possibly a small decline) in self-efficacy related to these tasks. Marketing educators are advised that a marketing simulation game is a viable option to consider when seeking to improve students' numeracy and financial skills.
