Variable expenses

Variable expenses will change in proportion to the production output of a good or service. These expenses will increase or decrease depending on production volume.

The startup costs to become an Uber driver are relatively minimal, provided you already own a car. However, the expense incurred for gas while driving for Uber will vary depending on the number of rides given.

The more rides given, the more miles driven, the more gas consumed, which will increase this expense to you as an Uber driver. Similarly, the expense incurred for gas will decrease as fewer rides are given.
