A 10-mile trip, pickup included, costs you $3.01 before you earn anything.
Three numbers to add
Fuel or charging
Divide what you pay for fuel by how far it takes you.
price per gallon ÷ miles per gallonUpkeep
Tires, oil and repairs grow with every mile. Use last year’s bills if you have them.
yearly upkeep ÷ yearly milesFixed costs
Insurance and fees do not care how far you drive, so spread them over your monthly miles.
monthly fixed costs ÷ monthly miles
