Definition At a given time the overall utility derived from the consumption of all units of a commodity is called Total Utility.
Definition of Marginal Utility Marginal Utility is the utility which is derived from the consumption of an additional unit of a commodity. In other words, it is the addition to total utility, resulting from adding one unit to the consumption of a commodity. Example : Ram consumes 6 ice creams at a time. In this case, 6 ice creams will be the marginal unit and utility derived by him from adding one unit to the consumption of a commodity.
