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.
