Diagram of how to make a correct calculation of Equipment cost

Applying the above table we have:

How to Calculate Equipment Cost per Hour – Fixed Costs per Hour


Depreciation charge:
D= [Vn-Vrev/Vu]

Average interest on investment = Im at the annual interest rate = i

The charge to be added to the cost of the equipment for the average interest of the investment is equal to:
The average value of the equipment by the annual interest, divided in 2000 hours per year.
Im = { [Vn + Vrev]/2 * 2000}*i

Cost of insurance, taxes, and storage

The costs for insurance, taxes, and annual storage fees are:
Insurance cost: 5.5% of the average value of the equipment.
Cost for taxes: 1.5% of the average value of the equipment.
Cost of storage 1.5% to 2% of average equipment value.
Hourly costs are obtained by dividing the amounts by the number of annual work hours, that is, 2000 hours.

Maintenance and repairs of machinery

Maintenance for repair and spares costs.
The cost per hour of maintenance for repair and spares is equal to:
Cost of maintenance for heavy work: 80 to 100% of the depreciation value.
Cost of maintenance for normal work: 70 to 90% of the depreciation value.
Cost of maintenance for light work: 50 to 80% of depreciation value.

Consumption costs


Usually, each company records the fuel consumption, for example, during one month and then divides that data into the monthly working time of the machinery, thus getting the hourly fuel consumption.
The hourly cost for fuel consumption is the product of the expense for the price of fuel.


The correct method for finding out the hourly consumption of oil in a machine is to record the engine, hydraulic, and transmission oil consumption for changes and refills at the end of each month and then divide each data into the monthly working time of the machinery.
The cost to be taken for oil consumption is obtained by multiplying the hourly consumption of oils by their price.

Cost per consumption of machine or equipment tires as a result of their use

The hourly cost is obtained by dividing the price of the tire over the economic life of the tire.
A 15% bonus is also charged with the depreciation of the tire for tire repair.

How to Calculate Equipment Cost per Hour – Operating Costs

Labor costs – Calculate Man Hours

The cost of the worker’s hourly wage, plus social security contributions multiplied by the percentage affected, is equal to the hourly cost of the worker.

Labor cost for surveillance

The hourly cost for surveillance is equal to:
10% of the cost of labor.

Total Cost

Adding the above charges, we arrive at the estimate of the hourly cost of the equipment.

Knowing the amount of direct and indirect personnel to be employed in the work and the trips to be made, we can estimate the number of vehicles to be used and their fuel and maintenance costs, etc.

In this phase, the quantities and costs of the manual tools to be used (one toolbox per officer is calculated), the machinery and special equipment, for example, welding machines, generators, optical levels, theodolites, amperometric tweezers, etc., should also be evaluated.

The equipment necessary for the daily transport of materials and machinery to the site must also be computed.
