David V. Auld
President and Chief Executive Officer at D.R. Horton
Thank you, Paul. Given that Paul is new to his role, he will not be an active participant today, but we are glad to have him with us and believe his extensive homebuilding experience will strengthen our executive team. The D.R Horton team finished the year with a strong fourth quarter, which included a 63% increase in consolidated pre-tax income to $1.7 billion and a 27% increase in revenue to $8.1 billion. Our pre-tax profit margin for the quarter improved 480 basis points to 21.3% and our earnings per diluted share increased 65% to $3.70.
For the year, consolidated pre-tax income increased 80% to $5.4 billion on a $27.8 billion of revenue. Our pre-tax profit margin for the year improved 460 basis points to 19.3% and our earnings per diluted share increased 78% to $11.41. We closed a record 81,965 homes this year, an increase of over 16,500 homes or 25% from last year. While also achieving a historical low homebuilding SG&A percentage of 7.3%, our homebuilding return on inventory was 37.9% and our return on equity was 31.6%. These results reflect our experienced teams in their production capabilities, our ability to leverage D.R Horton scale across our broad geographic footprint and our product positioning to offer homes at affordable price points across multiple brands.
Our homebuilding cash flow from operations for 2021 was $1.2 billion. Over the past five years, we have generated $5.9 billion of cash flow from homebuilding operations, while growing our consolidated revenues by 128% and our earnings per share by 383%. During this time, we also more than doubled our book value per share, reduced our homebuilding leverage 220% and increased our homebuilding liquidity by $2.8 billion, all while significantly increasing our returns on inventory and equity.
Housing market conditions remain very robust and we are focused on maximizing returns and increasing our market share further. However, there are still significant challenges in the supply chain, including shortages in certain building materials and tightness in the labor market. As a result, we continued restricting our home sales pace during the fourth quarter by selling homes later in the construction cycle to align with our production levels and better ensure certainty of home closing date for our homebuyers. We expect to work through the supply chain challenges and ultimately increase our production capacity. After starting construction on 22,400 homes, our homes and inventory increased 26% from a year ago to 47,800 homes at September 30, 2021. In October, we started more than 8,000 homes, further positioning us to achieve double-digit growth and again in 2022.
We believe our strong balance sheet, liquidity and a low leverage position us very well to operate effectively through changing economic conditions. We plan to maintain our flexible operational and financial position by generating strong cash flows from our homebuilding operations and managing our product offerings, incentives, home pricing sales pace and inventory levels to optimize our returns.
