To provide a risk distribution assessment device which can be used for making a risk distribution contract not only between business entities having reverse directional risks but also between business entities having the same directional risks.
This risk distribution assessment device 1 is provided with a weather risk assessment means 11 for assessing the weather risk of a business entity where weather fluctuation in a certain period in a year becomes the factor of revenue fluctuation and a risk distribution assessment means 12 for assessing risk quantity which can be distributed between the business entity and the other business entity based on the weather risk assessed by the weather risk assessing means 11. In this case, the weather risk assessing means 11 assesses the fixed rate of the fluctuation risk of business revenues due to the weather fluctuation of each business entity (the standard deviation of the probability distribution of the business revenues of each business subject to be calculated based on the past result data of each business entity and the weather data of the business area of each business entity) as the weather risk based on the past result data of each business entity and the weather data of the business area of each business entity.
