Fig 2: Average values calculated from internal market studies and
author´s experience.
The profitability of an elevator maintenance contract is calculated
based on the costs of preventive maintenance and corrective maintenance.
These must be summarized and analyzed. Corrective maintenance costs are
minimized when they are not required in the first place.
Figure 3 shows how the gross margin (GM) and the earnings before
interest, taxes, depreciation, and amortization (EBITDA) of each
maintenance contract are calculated, based on the sum of each elevator
included in the contract. In Figure 3, an example is specified, based on
the average market cost values of a local or regional company, which
are lower than the average cost values of a multinational. Depending
on each company and its market prices and operating costs, the GM and
EBITDA may vary.
