In a recent fleet study with our customer, GreaseBoss’ critical point monitoring solution has been proven to reduce annual failure risk by more than 50%. We built this fleet calculator as an interactive tool for maintenance teams, fleet owners, and reliability engineers to better understand the value of preventative monitoring technology at fleet scale.

The calculator borrows from public-health economics through the Number Needed to Monitor (NNM) framework, a way of quantifying how many assets must be monitored to prevent a single failure each year. NNM exposes what we call the prevention paradox. At the level of a single asset, the value of preventative technology is often invisible because most assets won’t fail in any given year. Once you zoom out to a fleet, the maths becomes definitive. Read our recent whitepaper to learn more.

FLEET SIZE (TRUCKS)
TRUCKS
Number of assets in your fleet
FAILURES PER YEAR iTotal expected failures across your fleet per year for the target failure mode. The fleet whitepaper standard works out to roughly 20% per asset (e.g. 8 failures on a 42-truck fleet). Adjust this if your fleet’s failure count differs.

How many asset failures is your site experiencing annually?
COST PER FAILURE iTotal cost of one failure event, including repair parts, labour, and lost production. Adjust to match your fleet’s typical event cost.

EXPECTED REDUCTION iThe percentage-point drop in annual failure probability that the technology delivers. For example, if your fleet had 10 failures/year, 50% means you’d expect roughly 5 after installing monitoring.

ASSUMPTIONS AND METHODOLOGY
Based on operational data from a recent fleet study. Technology costs: year zero includes hardware installation and the first year of licensing; years one onwards include annual licensing only. Total fleet-wide benefit across all lubrication-related failure modes will be materially higher.
Baseline annual failure rate: 20% per asset per year. Source: GreaseBoss Fleet Whitepaper. This figure has been standardised with our published methodology and reflects the observed annual rate for the target failure mode in the studied fleet.
Total cost per failure: Combines repair parts and labour with production loss during downtime. The default value reflects the fleet whitepaper analysis. Adjust the cost per failure input above to match your fleet’s typical event cost.
Currency conversion: USD values are calculated using an indicative AUD-to-USD rate of 0.72. Actual rates fluctuate; use this calculator as a directional guide rather than a pricing quote.
