The financial impact of unplanned equipment downtime and asset unavailability.
US$36,000–$2.3m per hour
Cost of an hour of unplanned downtime in industry
An hour of unplanned downtime costs from around US$36,000 in fast-moving consumer goods to US$2.3 million in a large automotive plant.
Scope: Siemens and Senseye surveyed mainly large manufacturers and major heavy-industry producers worldwide across automotive, heavy industry, FMCG, oil and gas and pharmaceuticals. The US$36,000 FMCG floor and US$2.3 million automotive ceiling appear on report pages 2-4; the report separately says SME losses can reach US$150,000 an hour at the top end on page 7. Sector sample mix varied between years, so the combined trend is indicative. Across the sectors surveyed, unplanned downtime costs an average large plant US$253 million a year.
$2,000–$10,000 per day
Daily cost of equipment downtime on construction sites
When critical equipment is unavailable on a construction site, project delays can cost between $2,000 and $10,000 per day in idle labour, missed milestones, and subcontractor penalties.
800 hours
Average annual unplanned downtime per manufacturing facility
The average manufacturing plant experiences approximately 800 hours of unplanned equipment downtime per year, equivalent to more than 15 hours per week.
up to 30–40%
Cost opportunity of moving off reactive-heavy maintenance
US Department of Energy analysis puts the savings opportunity of a predictive program at up to 30-40% versus reactive-heavy operations, with preventive alone saving 12-18%. Emergency work carries expedited parts, overtime labour and secondary damage. The often-quoted "reactive costs 3-9x more" multiplier has no checkable primary source, so we publish the DOE percentages instead.
Scope: US Department of Energy / PNNL O&M Best Practices Guide, Release 3.0, section 5.3 on preventive maintenance and section 5.4 on predictive maintenance, PDF pages 51-52. The guide reports 12-18% preventive-over-reactive savings, 8-12% predictive-over-preventive savings and opportunities exceeding 30-40% where a facility relies heavily on reactive maintenance.
11%
Annual revenue lost to unplanned downtime
Fortune Global 500 companies lose approximately 11% of their yearly revenue to unplanned downtime, amounting to nearly $1.5 trillion across those organisations.
Scope: Siemens / Senseye, The True Cost of Downtime 2024, executive summary on report pages 2-3. This is an estimate for the world's 500 largest companies by revenue, not a benchmark for a typical plant or smaller business.
40%
Equipment sits idle due to poor scheduling
Construction firms report that up to 40% of their equipment fleet is idle at any given time, often because managers lack real-time visibility into availability and location.
6 billion gallons per year
Fuel wasted through unnecessary commercial vehicle idling
Commercial vehicles waste approximately 6 billion gallons of fuel per year through unnecessary idling, costing fleet operators over US$20 billion annually. Telematics systems that alert managers and drivers to excessive idling are one of the most effective interventions for reducing this waste.
55–70%
Average fleet utilisation rate across commercial operators
Average fleet utilisation rates sit between 55 and 70%, meaning 30 to 45% of fleet capacity is idle at any given time. Best-in-class operators achieve 80 to 85% utilisation through real-time visibility, dynamic scheduling, and pooled asset sharing across projects and depots.
$50,000–$180,000 per year
Total cost of ownership for a single commercial vehicle
Total cost of ownership for a single commercial vehicle ranges from $50,000 to $180,000 per year, encompassing fuel, insurance, maintenance, depreciation, registration, and driver costs. Without accurate tracking, fleet managers often underestimate true per-vehicle costs by 20 to 30%.
$5,000–$10,000 per hour
Unplanned downtime cost for a large mining haul truck
Unplanned downtime for a large mining haul truck costs between $5,000 and $10,000 per hour, factoring in lost haulage capacity, idle crew wages, and contract penalties. In open-pit operations where every truck is scheduled against tight production targets, even a few hours of downtime can cascade into significant revenue loss.
$1,000–$5,000 per day
Average unplanned downtime cost for SMEs
Small and medium enterprises report average unplanned downtime costs of $1,000 to $5,000 per day, with 82% of affected businesses saying the impact is significant enough to warrant dedicated prevention investment. For many SMEs, a single week of equipment downtime can wipe out an entire month of profit.
~$1.4 trillion
Annual cost of unplanned downtime to the 500 largest companies
Unplanned downtime costs the 500 biggest companies in the world almost $1.4 trillion a year, equal to about 11% of their combined revenues, based on the Siemens 2024 True Cost of Downtime study.
Scope: Siemens / Senseye, The True Cost of Downtime 2024, executive summary on report pages 2-3. This is an estimate for the world's 500 largest companies by revenue and should not be generalised to a typical plant or smaller business.
27 hours a month
Production time an average large plant loses to unplanned downtime
The average large plant loses about 27 hours a month, more than a full day of production, to unplanned downtime across roughly 25 incidents, adding up to around 326 hours a year.
Scope: Siemens / Senseye, The True Cost of Downtime 2024, executive summary on report page 3. The survey mainly covers large manufacturers and major heavy-industry producers; 27 hours and 25 incidents are monthly averages per facility across the sectors surveyed.
40-50%
Share of equipment fleets report as underutilised
Fleet operators estimate that 40 to 50% of their equipment is underutilised or sits unused, and 67% report assets held onsite but unused at least some of the time, per the Teletrac Navman 2026 utilisation report.
$50 billion
Annual cost of unplanned downtime to industrial manufacturers
Deloitte estimates that unplanned downtime costs industrial manufacturers around $50 billion a year, and that poor maintenance strategies can cut productive capacity by 5 to 20%.
$2.3 million
Cost of one unproductive hour in automotive manufacturing
Automotive manufacturers now lose US$2.3 million for each unproductive hour, roughly double the 2019 figure, while heavy-industry downtime costs quadrupled over the same period, per the Siemens True Cost of Downtime 2024 study. The floor of the range is about $36,000 per hour in fast-moving consumer goods.
Scope: Siemens / Senseye, The True Cost of Downtime 2024, report pages 2-4. The US$2.3 million figure describes an unproductive hour at a large automotive plant; the US$36,000 floor describes FMCG. The survey mainly covers large manufacturers and major heavy-industry producers.
~US$125,000
Hourly cost of unplanned downtime for a typical industrial business
Unplanned downtime costs the typical industrial business close to US$125,000 per hour, based on an ABB Value of Reliability survey of 3,215 plant maintenance decision-makers conducted by Sapio Research in 2023.
2 in 3
Industrial businesses hit by unplanned outages at least monthly
Over two-thirds of industrial businesses experience unplanned outages at least once a month, and 21% still rely on run-to-fail maintenance, according to the 2023 ABB Value of Reliability survey.
