As soon as an asset is allocated to a goal, the software recalculates the Current Savings, Additional Suggested and the Achieved %. It calculates the future value of the asset and links it to the goal.
This results into lower monthly and lumpsum requirement as we assume the future value of the asset will be used towards funding the goal.
Also, since an asset is allocated to the goal, we update the Achieved %. You can read more about Achieved % here.
