Calculating Oil Analysis ROI: It’s Surprisingly Simple!

There are 4 reasons for keeping the measurement of oil analysis ROI simple:

  1. It’s less time consuming
  2. It reduces measurement errors
  3. It utilizes statistics that most companies have on hand
  4. It’s easier to convey to management.

                Albert Einstein’s advice was to “Keep things as simple as possible, but no simpler.” This applies to calculating the ROI of oil analysis. There are some very complex calculations out there that belong in a software program rather than a human head.[1]  And for those that do have the extra bandwidth to determine and input all those variables, explaining it all to management will likely result in a vacant stare rather than a congratulatory handshake.  Given this, it’s smart to always bear in mind that management will have to approve the initial and ongoing investment in the oil analysis program.            

                While the return on oil analysis is there whether the calculation is simple or complex, it’s best to keep things as straightforward as possible for management. There is always money available for investments that produce a healthy profit.

                There are three main costs to consider in the calculation: labor, parts and downtime. There are, however, other costs such as production time, production quality, energy and lubricants, that a more comprehensive calculation will factor in.

Example: ROI of Oil Analysis on Gearboxes[2]

Note that all of the metrics needed for this equation should either be readily available or easy to estimate.


  • Total number of gearboxes
  • Average gearbox failures per year
  • Parts cost per failure
  • Labor cost per failure
  • Loss of production cost per failure
  • Cost of production (if equipment had been operating) 
  • Annual cost of oil analysis for gearboxes


Annual cost of gearbox failures prior to institution of oil analysis program

Number of Gearboxes x Average Failures Per Year x ((Parts + Labor + (Loss of production- Cost of Production)) = Annual Cost of Gearbox Failures


Annual cost of gearbox failures after institution of oil analysis program

Number of Gearboxes x Average Failures Per Year x ((Parts + Labor + (Loss of production- Cost of Production)) = Annual Cost of Gearbox Failures


Annual Cost of Gearbox Oil Analysis


Annual Savings Using Oil Analysis on Gearboxes

ROI = (Annual Savings-Annual Cost)/Annual Cost

                This is a very simple, concise calculation that can easily be conveyed to management. While the cost of purchasing a piece of equipment is fixed, the total cost of ownership (TOC) is highly variable. One of the main drivers of variability is how well the equipment is maintained. The fact remains that, for most applications, oil analysis is one of the most cost-effective maintenance tools.
