TL;DR
Ford’s moving assembly line reduced the labor time to assemble a Model T chassis from 12 hours 28 minutes to 1 hour 33 minutes by early 1914, according to Henry Ford’s account. But the factory was struggling to keep workers: after 1913 turnover reached 370%, Ford raised minimum daily pay to $5 and shortened the working day to eight hours.
In January 1914, Ford Motor Co. cut its working day from nine hours to eight and raised minimum daily pay from $2.34 to $5, responding to severe difficulty retaining workers as its new moving assembly line sped up Model T production. The change became known as the five-dollar day; figures cited in a historical account show that Ford’s labor turnover had reached 370% in 1913, even as assembly time for a chassis fell sharply.
Ford’s own production figures, published by Henry Ford with journalist Samuel Crowther in the 1922 book My Life and Work, put the labor needed to assemble a Model T chassis at 12 hours 28 minutes when the work was done around a stationary car. By early 1914, after work was divided and the chassis moved along a line, the company said the time had fallen to 1 hour 33 minutes. That is about 88% less labor time, though the figures come from Ford’s account rather than an independent production audit.
The assembly-line experiments began with a smaller component, the flywheel magneto, in 1913. Ford’s account says the company split the task into 29 operations and moved the component past workers. It reported that assembly time fell from about 20 minutes per magneto to 13 minutes and 10 seconds, and later to five minutes after changes to the line. Ford said the general idea drew on overhead rails used in Chicago meatpacking plants.
Faster production did not solve the factory’s staffing problem. A 1987 study by economists Daniel Raff and Lawrence Summers, drawing on earlier labor research and company surveys, reported that Ford hired 50,448 people in 1913 to maintain an average workforce of 13,623. The historical account describes this as 370% turnover. In January 1914, Ford introduced the higher daily pay under a profit-sharing plan with conditions, alongside the shorter workday.
The Human Cost of Faster Production
The episode shows that the assembly line’s early effect was not simply to reduce the number of workers required. Ford’s production system sharply cut labor time per vehicle, while the company still needed a large workforce and struggled to keep people on the job. Its response linked workplace organization directly to wages and hours.
The five-dollar day is often explained as a way to help workers afford the cars they made. The account challenges that familiar interpretation: Ford’s immediate problem, based on the turnover figures it cites, was keeping workers in a plant where jobs were repetitive and labor demands had changed. The pay plan also came with eligibility conditions, so the advertised daily amount should not be treated as an unconditional wage for every employee.
The longer industrial significance is that productivity gains and job numbers do not move in a simple, immediate lockstep. The account notes that U.S. factory employment rose by about a third between 1910 and 1920, even as assembly methods changed. That national figure provides broader context, but does not by itself establish that Ford’s line caused the increase. Today, assembly lines remain central to manufacturing, though robots now perform more of the work.

From Stationary Chassis to Moving Line
Before Ford’s line experiments, workers assembled a car around a chassis that stayed in one place, bringing parts to it. Ford’s Highland Park plant in Detroit first tested a moving process on the magneto, then applied the approach to the chassis. In an early trial, workers pulled the chassis down a 250-foot route with a rope and windlass. Ford’s account says that version reduced chassis labor time to 5 hours 50 minutes; later changes divided the tasks further and raised the line to waist height.
The Model T was already a mass-produced product before the moving line reached full effect. Ford reported building 18,664 cars in the 1909–10 model year, when a touring car cost $950. Around 1914, the company had about 14,000 workers and produced about 250,000 cars a year, according to the account. These figures help explain why the five-dollar day is presented as a response to a workforce problem, not evidence that Ford lacked customers.
The source material also describes a crowd of job seekers outside a Detroit factory during a January 1914 blizzard. It says the New York Times reported that police used a water hose on the crowd in near-zero weather, and that applicants returned after drying off or changing clothes. The scene underscores the contrast between workers seeking jobs and Ford’s difficulty retaining the people it had hired.
““the reduction of the necessity for thought on the part of the worker and the reduction of his movements to a minimum.””

Limits of Ford’s Production Figures
The production-time figures are drawn from Ford’s 1922 account, which is the company’s version of its own industrial history. The turnover figures are attributed to the 1987 study by Raff and Summers, based on earlier research and company surveys; a Henry Ford museum account gives a slightly higher turnover figure of about 380%. The available material does not reconcile the difference, so the figures should not be treated as identical measurements.
The exact reach of the five-dollar plan is also not fully detailed here. It was described as profit sharing with strict conditions, but the source does not list every eligibility rule or show how many workers actually received the full amount. Nor does the cited material establish how much the line itself, rather than other workplace conditions, contributed to each worker’s decision to leave.
How the Line Changed Work
The historical account traces the consequences beyond the 1914 pay decision, noting the growth in U.S. factory employment from 1910 to 1920 and the continuing role of assembly lines in manufacturing. It also points to greater use of robots on modern lines. Those developments provide a longer view, but the material does not set out a new study or forthcoming event.
The next step for readers assessing the episode is to distinguish Ford’s production claims from the independently compiled turnover research and to keep the five-dollar day’s conditions in view. The account’s central finding is that faster production and worker retention were linked problems at Ford in 1913 and 1914, while the precise contribution of each factor remains difficult to isolate from the evidence presented.
Key Questions
What changed at Ford in January 1914?
Ford shortened the workday from nine hours to eight and raised minimum daily pay from $2.34 to $5 through a profit-sharing plan with conditions.
How much faster did the assembly line make chassis assembly?
Ford’s account said labor time fell from 12 hours 28 minutes per chassis at a standstill to 1 hour 33 minutes on the moving line by early 1914. These are company figures published later by Henry Ford and Samuel Crowther.
Why did Ford introduce the five-dollar day?
The historical account presents it primarily as a response to high employee turnover. Ford’s 1913 hiring figures show the company hired 50,448 people to maintain an average workforce of 13,623; the pay plan also had conditions.
Did Ford raise wages so workers could buy its cars?
The source describes that explanation as a popular legend and says the evidence presented points instead to worker retention as Ford’s immediate concern. The material does not establish that no other motives played a part.
