The number you see first
An offer shows a payout. That is useful information, but it says little about what the drive will cost you. Distance, unpaid travel and the time between deliveries all shape the result.
Give the miles a price
Suppose an example offer pays $22.50. Delivery and return travel total 9.2 miles. At 28 MPG, $3.50 a gallon and $0.20 per mile of vehicle wear, estimated driving cost is $2.99. The estimated margin is $19.51 before other business costs and taxes.
Give your time a place
For a 28-minute example, that margin corresponds to $41.81 per hour while completing the offer. Waiting, repositioning and other unpaid time can make a whole workday’s hourly result lower. Track the full workday to understand that wider picture.
Compare to your own goals
Your vehicle and priorities matter. Set your own costs and targets, then use the calculator as a consistent check. Revisit your assumptions as fuel prices and maintenance needs change.
