When calculating the benefits per month, the system calculates the benefit per day using the total days of the benefit period. If the benefits end date is empty, it will assume that the benefit is annualized so it will use 365 days as the benefit period. However, if you specify the benefits end date, the system will calculate the benefit period as the difference between the benefits start date and the benefits end date.
However, you can also use the benefits end date to specify the date that the system should stop tracking the benefits. For example, you may wish to only track the benefits of the idea for 2 years. In that case, the system will calculate the benefit period as (730 days). If you check the Annualized Benefit flag for the idea, the system will always use 365 days for the benefit period, irrespective of what the benefits end date is.
