The most likely amount method should be used to estimate the amount of variable consideration when the future events are highly uncertain and the most likely amount is difficult to estimate. In this method, companies consider the most probable outcome based on the available information and make their estimation accordingly. This approach is suitable when there is a lack of reliable data and when the future events are highly unpredictable.
