Insurance premiums for seasonal products may be generated. The insurance premium may be calculated by determining a historic seasonal variation in aggregate risk to an insurer; determining a predicted seasonal variation in aggregate risk to the insurer; and generating a premium installment payment schedule. The predicted seasonal variation in aggregate risk to the insurer may be based on the historical seasonal variation in aggregate risk. The premium installment payment schedule may be based on the predicted seasonal variation in aggregate risk. The monthly insurance premium may vary throughout the year and be based on a seasonal predicted risk to an insurer.
