The invention relates to an electric meter (1) for measuring the electric consumption of an electric load (RLOAD), in particular while charging an electric vehicle. The electric meter according to the invention has a current measuring device (11) in order to measure a charging current (ILOAD) which flows through a charging cable (7) to a transfer point (9, 10) for the load (RLOAD), wherein the transfer point (9, 10) is preferably located in a plug (8) of the charging cable (7). Furthermore, the electric meter (1) according to the invention includes a voltage measuring device (12) for measuring a voltage. According to the invention, the voltage measuring device (12) measures the voltage directly at the transfer point (9, 10) of the charging cable (7) in order to determine line losses in the charging cable (7), in particular in order to take into consideration the line losses when calculating the consumption.
