How much does an airless pump cost per hour of operation? This question comes up regularly in discussions with our customers when it comes to whether **buying an airless sprayer** is cost-effective.

In our new article, we have put together a simple calculation for three examples of professional airless pumps. You can easily understand the calculation and adapt it to your needs.

**What information is needed to calculate an hour of operation of an airless pump?**

Based on the initial data consisting of acquisition costs, depreciation period, interest rate, life span and annual costs consisting of depreciation per year, maintenance and repairs, the hourly operating rate can be calculated to the penny.

And if numbers aren’t your thing, ask your accountant **about year-end tax deductions** so you can purchase and deduct an airless pump from your bottom line.

**Initial data**

In the initial data, we have taken into account the net acquisition costs of the airless device, i.e. without VAT. The tax office in Germany assumes a lifetime of 5 years (this element must be verified with the tax center in your country of residence), so the depreciation is 20% of the new value per year. After 5 years, the airless machine has a book value of 0€ for the tax office. Therefore we also assume a useful life of only 5 years in our calculation, although with good maintenance the equipment can be used much longer.

Regarding the interest rate, we have calculated only 1%, although it should be difficult to get this interest rate in a bank at the moment. As an example, we calculate the useful life of the airless with 10 hours per week, with 52 weeks per year. As there will certainly be some holidays, we have calculated with 48 weeks of 10 hours each and thus arrive at 480 operating hours per year. These values must of course be adapted to each individual case.

- Acquisition cost / initial cost (net)
- Interest rate
- Amortization period
- Number of hours of use per year

**Annual costs**

Annual costs result from depreciation, which is 20% of the new value of the sprayer, plus interest charges per year. Maintenance and repair can usually be covered by an average flat rate of 10% of the purchase price. Adding these costs together gives the annual operating costs.

- Annual tax deduction (20%)
- Interest rate
- Repair costs (10%)
- Total annual costs

**Cost per hour**

The costs per operating hour are the annual costs divided by the operating hours per year.

- Annual costs / hours of operation

**Calculation example for the Wagner SF 23 Plus pump**

The **Wagner SF 23 Plus** is a light-weight painting station that can be used for spraying varnishes and glazes, but also for applying interior wall paint.

The fields of application of the painter’s trade range from painting of radiators, windows, doors, walls and ceilings of apartments or single-family houses.

The calculation takes into account the current purchase price and a useful life of only five years. The useful life is calculated at approximately 10 hours per working week. For maintenance and repair, 10% of the purchase price is taken into account.

**Sample calculation for the Graco Ultra Max II 695 Standard pump**

The **Graco Ultra Max II 695 Standard** is a popular sprayer when it comes to spraying facade paint, adhesives but also interior wall paint and primer. Because of its performance, this Graco pump can also be used for roof coating.

In calculating the operating costs of this airless pump, we also assume a relatively short service life of only 5 years and an interest rate of 1%. The annual usage in the example calculation is also 480 operating hours.

**Sample calculation for the Graco Mark VII Procontractor pump**

The **Graco Mark VII ProContractor** is a multi-talented pump. It can spray anything from primer to adhesive, from interior wall and facade paint to fire protection and plaster. In short, you can do just about anything with this airless pump for large jobs.

For the comparison with the Wagner SF 23 Plus and the Graco Ultra Max II 695 Standard, we base this calculation on the same data as before.

**Where does the calculation reach its limits?**

We tried to make the calculation as accurate as possible, but we also wanted to avoid making it too complicated.

Of course there are limits to the calculation or points that are not or not completely taken into account. We have summarized these points here.

**5 year useful life – depreciation of the airless pump**

In our example calculation, we assume a useful life of 5 years. Even though professional airless machines can be used much longer with proper care and maintenance.

Why do we assume 5 years? The tax system in Germany allows the equipment to be amortized over several years, i.e. at a rate of 20% per year. After 5 years, the equipment has a book value of 0€. We have therefore taken into account the value of 5 years indicated by the tax authorities for the calculation example.

With a shorter useful life, the costs per hour of operation naturally increase; with a use beyond 5 years, the operating costs per hour decrease, because the purchase price decreases proportionally per year.

**Operating hours per year – 480 hours**

We have assumed 480 hours of operation per year in our example calculation.

For users who use the sprayer much less, the costs per operating hour increase. If the sprayer is used much more often, the operating costs per hour decrease. Maintenance and repair costs increase or decrease accordingly.

**Maintenance and repairs**

We have calculated the maintenance and repair at a flat rate of 10% of the replacement value per year. This is a common value for machines in the industry.

The costs for maintenance and repair are of course dependent on various factors. First of all, the period of use or the amount of material processed with the machine. I can spray 3 liters in one hour, but I can also spray 50 liters.

The material also plays a role, because materials such as silicate paint or plaster put much more strain on an airless machine than paint or varnish, so there can be different degrees of wear and tear depending on the material and the application.

The use itself (e.g. pressure adjustment) and the maintenance also have an impact on the maintenance and repair costs.

**What costs are not taken into account?**

Storage costs and electricity costs for operating the machine are not taken into account. In the overall calculation, these costs are rather small; moreover, they can vary greatly and would unnecessarily complicate our calculation. Therefore, we have not included these costs in our article.

The same applies to consumables such as nozzles, filters and maintenance products, as the demand depends strongly on the project and the application.
