To calculate a rental, you would multiply the total cost of a piece of equipment x 5% / month x 13 x 80% to arrive at the estimated annual rental dollars a rental company wants to achieve. By doing this, they would generate a 35% to 40% gross profit, which includes maintenance, insurance and the limited fuel they fund.2020-05-28
