With a current budget of $3.9 billion, the upcoming Beijing Winter Olympics will be relatively cheap by modern standards for the Games. The cost of Tokyo 2020 was almost twice the initial budget, and doesn't even count infrastructure spending. Indeed, cost overruns are a given for the Olympics, which since 1960 have always gone over budget — roughly by 173 percent on average. Given that national governments end up footing most of the bill, it's no surprise that in recent years fewer cities have competed to host the Games, and that Brisbane's 2032 bid was unopposed. We rank the last 16 Olympics by how much their final cost exceeded their initial budget.
