That is {value} of stock per plant. Mid-size plants hold roughly $1 million to $60 million each.

Spare parts bought a year is usually 35–75% of stock value; yours is {ratio}%. Check one of the two.

Estimated stock value: {value}
Records in the material master times the average value of a part. It assumes about one unit on the shelf per record, so treat it as an upper bound.
Typical: 27 unplanned hours a month per plant (Siemens 2024), of which about 23% wait for a part (a maintenance survey cited as Plant Engineering 2025).
That is {hours} hours a year waiting for parts.
$
About $25,000 an hour on average (MaintainX 2024); ABB 2023 puts the median at about $125,000. Use contribution margin per hour times the share of capacity lost, not revenue.

a year: paid back in the first week paid back in {n} weeks paid back in {n} months Example budget a year, replace it with yours. The multiple is this estimate against your own figure, not a Partium price.
Cost of carrying that stock, every year
a year
Estimated. Holding cost of 20–30% of part value a year (Erasmus University 2013), upper end; Deloitte 2024: 25–35%. Applied to the stock released, not to all of it.
Buying at the right price
a year
Estimated. Partium platform claim: up to 37% lower procurement costs on the parts re-sourced. One example: buy a part from its original manufacturer instead of through the machine builder that resold it; machine builders charge about 35% above the original manufacturer's price, by an industry benchmark. Ardent Partners 2024: best-in-class procurement saves 9.2% of all spend.
Time not spent searching
a year
Estimated. Aberdeen: 4.9 hours a week less searching with clean master data, about what 10 searches at 30 minutes add up to. At Deutsche Bahn, 46,800 person-days saved in one year.
Orders that cost more to place than the part
a year
Estimated. BME: about €120 per purchase order on average, €30 at the best firms; the difference on each of your orders.
Downtime that waited for a part
a year
not counted
Estimated. 75% of the hours avoidable: Aberdeen reports stock-out downtimes cut from four a month per plant to one. Cost per hour is your figure.
Also in your data, not counted in money
Duplicate records in your master, estimated at 9% (one multi-site manufacturer, Reliable Plant). Industry benchmark by sector: automotive 8–12%, pharmaceutical 5–10%, chemical 10–15%, minerals 8–13%, food and beverage 7–12%. · Duplicate Monitor
Records Partium can complete, estimated at 60% (platform claim: 30–60%). · Data Enhancement Monitor
Up to 20% less obsolete stock when plants share what they hold (Carlisle Group). · Inventory Optimization
How we estimate
Each lever is your figure times a rate. The rates sit at the upper end of what has been published, and you can move every one. No figure is counted twice, and no figure on this page is a customer result.
Figures from Partium are published platform claims. Figures from analysts and studies are quoted at the upper end of their published range and marked estimated. Industry benchmarks are the ranges tools in this market use.
