At the request of ARA members, ARA convened a workgroup in September 2012 to develop a plan of work for estimating an appropriate measure of equipment rental penetration for the equipment rental industry.
The workgroup built upon ARA’s development of rental-specific performance metrics to determine a way to calculate rental penetration that combines several factors to result in the ARA Equipment Rental Penetration Index.
The ARA Equipment Rental Penetration Index provides the industry with a new method for measuring and forecasting equipment rental penetration and leverages the ARA Rental Market Monitor and the expertise of the association’s industry research partner, IHS Global Insight, as the foundation.
The ARA Equipment Rental Penetration Index is designed to create a way for rental companies to measure how much potential market exists versus the current market as well as for manufacturers to project demand for machines, and investors and analysts to consistently measure trends about equipment rental in construction.
U.S. Census data is used to calculate a value-based measure of the construction fleet. Using this value as the denominator and rental fleet OEC as the numerator, ARA can estimate an equipment rental penetration index that is value-based and accounts for flows of equipment into and out of the fleet and for the stock of equipment in the rental and total construction fleets.
ARA used the index to analyze results covering 2003-2011, which shows rental penetration for construction machines was in the range of 40 percent at the beginning of the analysis to just above 50 percent in 2010 and 2011. The result is consistent with the expectation that in recent years the size of the rental fleet has increased relative to the construction fleet.
