Attachment loss calculator.
Put in your own numbers to see what missing buckets, breakers and other attachments cost each year, and how much tracking has to save to pay for itself.
How the sum works.
- Missing attachments
- attachments in the register × share not found
- Cost of missing attachments
- missing attachments × replacement price
- Cost of search time
- hours a month × 12 × cost per hour
- Break-even
- software per year ÷ total cost
What to do with the number.
If the total is higher than the yearly cost of tracking, start with one yard. Tag the attachments first: they have no telematics of their own.

Hirro keeps a living inventory of every machine, attachment and piece of small kit, from the yard to the site. The numbers below come from our field test on a Belgian rental and crane yard, 16 to 23 October 2026.

Questions buyers ask.
Where does the share not found come from?
Take the assets your last count could not find and divide by the assets in the register. If you have never counted, use what you bought or rented in last year to replace missing kit.
Which price should I use?
Use the average of what a replacement costs you today. For a mixed fleet, run the calculator once for attachments and once for small kit.
