Abstract: This article derives a simple method for projecting pension deficit as percent of GDP in future years based on commonly available population forecasting and a few predictable economic and policy variables. Compared with the classic basic equilibrium equation of pension funds, our new formula decomposes the retirees-workers ratio which mixes various kinds of impacts into three more-easily-predictable variables the elderly dependent ratio, the prevalence of pension coverage, and the employment rate. Our illustrative application to China shows that gradually increasing the current low minimum age of retirement will largely reduce the pension deficit, under various demographic regimes. The pension deficit as % of GDP in the low fertility scenarios (which corresponds with keeping the current rigid fertility control policy unchanged in the long-run) would be 5.6-11.1, 3.8-6.3, and 9.0-13.8 times as high as that in the Medium Fertility & Medium Mortality scenarios in 2040, 2060, and 2080.
