SimIns is a computerized tool to aid in making health financing policy decisions. It does so by projecting health expenditure and funding for a 10 year time period. Thereby it allows to evaluate the feasibility of alternative mixes of financing sources, including social health insurance, community-based health insurance and government budget lines. It can be applied to both existing or planned schemes.
