I estimated that the delivery, pick-up, and insurance would cost $300 each time I rented. I would also have to buy the fuel for which I used my earlier estimate of $3.25 per hour. My total estimated hourly costs for renting an excavator thus came to ($1000 + $300) / 25 hours + $3.25 per hour = $55.25 per hour.
