A monitoring system for a paving machine having a screed may include an input device configured to receive a first input from an operator of the paving machine, the first input being indicative of a height of the screed above a work surface, and a controller electronically connected to the input device. The controller may be configured to determine an amount of a material deposited by the paving machine based on the first input, receive a signal indicative of an amount of a material delivered to the paving machine, and determine a correction factor based on the amount of the material deposited by the paving machine and the amount of the material delivered to the paving machine.
