Equipment Downtime Cost Calculator
An idle 20-tonne excavator costs about US$131 a day to own at California's 2026-27 equipment rates, and an operator paid to wait beside it about US$229 more at the US median wage (May 2025), so one stopped machine and its operator cost about US$360 a day before any repair. If the stoppage delays a Florida road contract of US$5 million to under US$10 million, the state's late-completion charge adds US$3,498 a day. Pick your machine, count and days below: every rate links to its public source, and the schedules are shown side by side, never averaged.
Or switch to Your records to model annual unplanned downtime cost from your own event, duration and hourly-cost records, test a target scenario, inspect the formula and download the assumptions with the result.
What this model does and does not do
Your records
Event count, duration, hourly cost and asset count come from you.
Visible formula
The calculator multiplies the inputs. It adds no hidden productivity or industry factor.
User-set target
The reduction percentage is a planning scenario, not evidence of a likely result.
This is an input-based scenario model, not an industry benchmark, quote or MapTrack performance forecast. Replace every example value with your own records before using the result in a decision.
Where the public rates come from
- Caltrans 2026-27: California's rates for owned equipment, excluding the operator. Idle time on an excusable delay is paid at the rental rate times the machine class's delay factor, for at most eight hours a day. Caltrans notes its calculated rates are likely lower than a hire yard's.
- FEMA 2025: all-in rates for disaster work that include fuel, tyres and repairs and exclude the operator, so a FEMA line values the lost work rather than the cash spent. Rows are recorded here for the Bobcat S76 skid steer and the Cat D6 crawler dozer; other machines show “Not published for this machine”.
- Army Corps 2022: a Region 1 standby row from the 2022 pamphlet, shown for the Cat 320 as a cross-check. Its vintage note says to use it for the ratio and the method, not as a 2026 rate, so it never sets the headline range.
- FDOT FY 2026-27: one state's contract late-completion charge per calendar day, set by contract size and charged once per contract, never per machine.
- US BLS May 2025: the median wage of a US construction equipment operator. It excludes payroll tax, insurance and benefits, so the real cost of paid standby time is higher.
The schedules differ because their base years, regions and purposes differ, so they are published side by side and never averaged. Results exclude repairs, replacement hire and lost revenue, and every rate stays in US dollars, its source currency. Each figure's card on the equipment downtime cost statistics page shows the source rows and the arithmetic.
Public-rate presets are one US state or federal schedule's rate for one named machine. They are a starting point, not a benchmark for your fleet. Replace them with your own hire or ownership rate when you have it.

What does equipment downtime really cost your business?
An unplanned stoppage can create costs beyond the repair itself: idle labour, replacement hire, delayed work and lost throughput. Which items apply, and their value, depend on the asset and the operation.
Direct costs include repair labour, replacement parts, and equipment hire to cover the gap. Keep indirect effects separate and include them only where you have a defensible method. That prevents a business case from counting the same loss twice or treating a possible consequence as a certain cost.
How to calculate unplanned equipment downtime costs
The core formula is straightforward: multiply the number of downtime events by the average recovery time and the cost per hour of lost operations. Define the start and end of an event before collecting data. A consistent definition matters more than using somebody else's hourly benchmark.
Start with a representative period and extend it where operations are seasonal. Record stoppage duration, the affected asset and each cost component without double-counting. Our tool loss calculator can help you quantify the cost of misplaced tools specifically, while the ROI calculator provides a separate input-based implementation scenario.
How to build a defensible reduction scenario
Start by coding each event by cause, duration and cost. Then isolate the causes a proposed change could plausibly affect. A NIST-published 2021 analysis of 71 usable, self-reported US discrete-manufacturing responses found 52.7% less unplanned downtime in the group that relied less on reactive maintenance. The authors say the grouped comparison should be treated as anecdotal evidence. It is observational, not a causal forecast for your fleet or for MapTrack. Read the NIST-published paper and our guide on types of maintenance for a breakdown of reactive, preventive, predictive, and condition-based strategies.
Configured maintenance scheduling and work-order records can help a team record due work and service history. Meter-based schedules depend on valid readings and a configured data source. Combined with accurate downtime cost data, you can prioritise the assets and failure modes represented in your own data, then compare observed results with the target.
Record your own stoppages
A public rate is a starting point. To price your own fleet, record each stoppage with the free downtime cost tracking log or the equipment downtime report template, then switch to Your records above. For the terms, see downtime and mean time to repair (MTTR).

Frequently asked questions
How much does unplanned equipment downtime cost?
There is no universal hourly or daily downtime cost. Use your own recorded event count and return-to-service time, then build an hourly cost from supportable items such as idle labour, replacement hire, lost throughput and contractual consequences. Keep repair cost separate if it is already counted elsewhere.
How is the downtime cost calculated?
In Your records mode, annual downtime cost equals monthly downtime events multiplied by 12, average hours per event and your downtime cost per hour. The target difference is that result multiplied by the reduction percentage you choose. No productivity, industry or MapTrack performance factor is added behind the scenes.
Does the calculator use industry benchmarks?
No. The public-rate presets are one US state or federal schedule's rate for one named machine, each linked to its source and shown side by side, never averaged, and the Your records values are labelled examples, not industry averages. Replace every input with your own records. The reduction percentage is a user-set planning target, not a prediction of what maintenance software or asset tracking will deliver.
How should I choose the reduction target?
Start with your coded downtime history. Identify the causes a proposed change could plausibly affect, then set a target against those events rather than all downtime. Keep the target separate from observed results and update the model after a representative measurement period.
What is the difference between planned and unplanned downtime?
Planned downtime is scheduled service, inspection or other work that can be prepared for. Unplanned downtime is an unscheduled loss of availability. Record the two separately because their operational consequences, causes and improvement options differ. See our guide to maintenance types for the operating differences between reactive, preventive and predictive approaches.
Can I download the results as a PDF?
Yes, in Your records mode. The PDF records your inputs, the formula, annual downtime hours and cost, the user-set target difference and the remaining exposure. It also repeats the model limitations so the result is not mistaken for a benchmark or forecast. If you want help mapping the inputs to your records, book a demo and we can talk through the model with you.
How do I calculate what an idle machine costs?
Multiply the machine's hourly rate by its delay factor and the idle hours, add the wages of anyone paid to wait, then add any contract charge the delay triggers. For a 20-tonne excavator at California's 2026-27 equipment rates that is US$96.41 x 0.17 x 8 hours, about US$131 a day, plus about US$229 for an operator paid the US median wage of US$28.66 an hour (US Bureau of Labor Statistics, May 2025), or about US$360 a day. Show the working under the result lists every operand with its source.
Why do Caltrans, FEMA and Army Corps give different numbers?
They measure different things. Caltrans' 2026-27 delay rate prices owning a machine while it stands idle, excluding the operator, for at most eight hours a day. FEMA's 2025 rate is an all-in rate for disaster work that includes fuel, tyres and repairs, so it values the lost work rather than the cash spent. The Army Corps standby row is a 2022 regional figure: for a Cat 320 it is US$9.44 an hour, 13 per cent of its US$70.59 working rate, against Caltrans' 0.17 delay factor. Base years, regions and purposes differ, so the calculator shows them side by side and never averages them.
Can I use these US rates in Australia?
Not as Australian rates. These are US state and federal schedules, our statistics page carries no Australian public equivalent, and Australian hire and wage rates differ. Use the presets to see the method, then pick Your own rate and enter your hire or ownership rate card, or switch to Your records to work from your own stoppage history.
How do I cite a result?
Copy citation gives a one-sentence summary that names each schedule with its year and ends with this page's address. Copy result card gives an HTML card with a normal link back to this calculator. Copy link to this scenario keeps your inputs after the # in the link, so it always points at this page. Cite each underlying rate to its card on MapTrack's equipment downtime cost statistics page.
