What it means
Durable goods generally have a useful life of at least three years, such as machinery, computers, appliances and vehicles, and the orders measure captures new orders that manufacturers accept during the reporting period. Transportation equipment can dominate a monthly change because a small number of aircraft or vehicle orders may be very large.
Removing that category helps analysts inspect the underlying movement across other durable goods. The Census table reports total new orders and a separate line excluding transportation, and the difference between the two is the transportation component for the same period and reporting basis.
An order is not a shipment. A factory may book a machine today, build it over several months and ship it later, so analysts should not treat booked demand as immediate production or recognised revenue.
Core durable orders are not identical to orders for nondefense capital goods excluding aircraft. The latter focuses on a subset often used to gauge business-equipment investment, while the broader excluding-transportation total includes other durable categories and so contains both consumer-related and business-related purchases.
When core orders rise, firms may have more work scheduled, but order cancellations, supply constraints and delivery delays can weaken the connection to later production. A one-month percentage change can reflect calendar effects, a strike, unusual contracts or a revision to earlier estimates, so review several months and whether the series is seasonally adjusted before drawing a trend.
The Census advance estimate is released before all details are final and may later be revised, and a manager should note the publication vintage when comparing a forecast against actual results. Percentage changes compare two levels with a common basis: a 2% rise from $200 billion adds $4 billion, but a revision to the prior month can change the reported percentage without new current orders.
An excluding-transportation figure can increase while the total falls if transport orders drop sharply, and the reverse can happen after a large aircraft contract even when demand elsewhere weakens. Inflation can raise nominal order values even when physical units do not rise, so compare prices, volume evidence and the broader manufacturing picture when judging real demand.
Core orders should not be interpreted as exclusively household spending or exclusively capital expenditure. Businesses can use the measure alongside their own order books, industry surveys and inventories, because a national aggregate may miss a company's product mix or export market.
Investors sometimes use durable orders to assess the economic cycle, but the measure is not a stand-alone buy or sell signal, since interest rates, profits, valuations and market expectations also affect security prices. A non-finance manager should ask which part of the change matters to their industry, because a firm selling industrial tools may find the machinery lines more informative than the broad core aggregate.
In practice
Real-world examples.
Example
New durable orders total $300 billion, including $90 billion for transportation. Excluding transportation leaves $210 billion in core orders for that reporting period.
Example
An airline places a very large aircraft order while other durable categories fall. The headline total rises, but the core series shows weaker demand outside transport.
Example
A factory receives a $5 million machine order in September with delivery in January. It appears in new orders when booked under the reporting rules, not as a September shipment.
Formula
Calculation
Core durable goods new orders = total durable goods new orders minus transportation-equipment new orders on the same reporting basis. With a $300 billion total and $90 billion transport, core is $210 billion. Month-over-month change = (current core orders minus prior core orders) divided by prior core orders. If the prior value was $205 billion, the rise is ($210 billion - $205 billion) / $205 billion = about 2.44%.
A second case shows why the exclusion matters. Suppose the prior month had a $280 billion total with $80 billion of transportation, so core was $200 billion. If the current month shows a $300 billion total with $95 billion of transportation, core is $205 billion. The headline rises by ($300 billion - $280 billion) / $280 billion = 7.1%, but core rises by ($205 billion - $200 billion) / $200 billion = 2.5%.Case study
Seen in the real world.
Fictional case: A parts supplier sees an 8% jump in total durable orders and considers adding a night shift. Its analyst checks the Census excluding-transportation line and finds it rose only 1%, while an aircraft order drove most of the headline increase. The supplier sells to appliance makers, not aircraft manufacturers, so it checks appliance orders and its own backlog before hiring.
It also notes that preliminary figures can be revised. The team adds temporary overtime for its confirmed orders but delays permanent hiring. The core series helped isolate the shock; it did not replace product-level forecasts.
Watch out
Common mistakes.
- Treating new orders as goods already shipped or revenue already earned.
- Confusing all durable orders excluding transport with the narrower nondefense-capital-goods-excluding-aircraft series.
- Inferring an economic trend from one preliminary month without checking revisions and category detail.
Questions
People also ask.
Why exclude transportation?
Large aircraft and vehicle contracts can make the total orders series volatile from month to month.
Are these inflation-adjusted units?
The cited Census table reports dollar amounts; nominal changes need careful interpretation alongside price evidence.
Does a higher reading guarantee more production?
No. Cancellations, inventories, supply limits and timing can affect eventual shipments.
