Richard McPhail
Executive Vice President & Chief Financial Officer at Home Depot
Thank you, Billy, and good morning, everyone.
In the fourth quarter, total sales were $34.8 billion, a decrease of 2.9% from last year. During the fourth quarter, our total company comps were negative 3.5% with comps of negative 2.5% in November, positive 1.1% in December and negative 8.5% in January. Comps in the US were negative 4% for the quarter with comps of negative 2.7% in November, positive 0.6% in December and negative 9.1% in January. In local currency, Mexico and Canada posted comps above the company average with Mexico posting positive comps. It is important to note that adjusting for holiday shifts and weather-related impacts in January, monthly comps relatively consistent across the quarter. For the year, our sales totaled $152.7 billion, a decrease of 3% versus fiscal 2022. For the year, total company comp sales decreased 3.2% and US comp sales decreased 3.5%.
In the fourth quarter, our gross margin was approximately 33.1%, a decrease of 20 basis points from last year. For the year, our gross margin was approximately 33.4%, a decrease of 15 basis points from last year, which was in line with our expectations.
During the fourth quarter, operating expenses as a percentage of sales increased approximately 115 basis points to 21.2% compared to the fourth quarter of 2022. Our operating expense performance during the fourth quarter reflects our previously executed compensation increases for hourly associates as well as deleverage from our top line results. For the year, operating expenses were approximately 19.2% of sales, representing an increase of approximately 90 basis points from fiscal 2022. Our operating margin for the fourth quarter was approximately 11.9% and for the year was approximately 14.2%. Interest and other expense for the fourth quarter increased by $50 million to $458 million. In the fourth quarter and for fiscal 2023, our effective tax rate was 24%.
Our diluted earnings per share for the fourth quarter were $2.82, a decrease of 14.5% compared to the fourth quarter of 2022. Diluted earnings per share for fiscal 2023 were $15.11, a decrease of 9.5% compared to fiscal 2022. At the end of the quarter, merchandise inventories were $21 billion, down $3.9 billion or approximately 16% versus last year, and inventory turns were 4.3x, up from 4.2x from the second period last year.
Moving on to capital allocation. During the fourth quarter, we invested approximately $860 million back into our business in the form of capital expenditures. This brings total capital expenditures for fiscal 2023 to approximately $3.2 billion. During the year, we opened 13 new stores, bringing our store count to 2,335 at the end of fiscal 2023. Retail selling square footage was approximately 242 million square feet and total sales per retail square foot were approximately $605 in fiscal 2023. Additionally, we invested approximately $1.5 billion on three acquisitions during fiscal 2023, accelerating our strategic initiatives and providing us with better capabilities to serve our customers. During the year, we paid approximately $8.4 billion of dividends to our shareholders.
Today, we announced our Board of Directors increased our quarterly dividend by 7.7% to $2.25 per share, which equates to an annual dividend of $9 per share. And finally, during fiscal 2023, we returned approximately $8 billion to our shareholders in the form of share repurchases, including $1.5 billion in the fourth quarter. Computed on the average of beginning and ending long-term debt and equity for the trailing 12 months, return on invested capital was 36.7% compared to 44.6% at the end of the fourth quarter of fiscal 2022.
Now I'll comment on our outlook for 2024. First, let me point out that fiscal 2024 will include a 53rd week, so the fourth quarter of fiscal 2024 will consist of 14 weeks. We will continue to report comps on a 52-week basis, but we will base our overall guidance on 53 weeks. As you heard from Ted, we feel great about the actions we took in 2023 to position us well heading into 2024. And while there are signs that the economy is on the way towards normalization, the home improvement market still faces headwinds as we look ahead to fiscal 2024. We considered several factors that informed our outlook for fiscal 2024. On the positive side, we faced a number of pressures in fiscal 2023 that are unlikely to repeat in fiscal 2024.
In 2023, we saw four increases in the Fed funds rate, a sharp decline in existing home sales and approximately 110 basis points of comp pressure from lumber deflation. However, we still expect pressures to our business in fiscal 2024. Personal consumption growth as measured by PCE is expected to decelerate compared to 2023. Our share of PCE also remains slightly elevated relative to 2019 and has been on a glide path towards 2019 levels. Higher interest rates at the beginning of 2024 relative to last year will likely continue to pressure demand for larger projects. And the effects from pull forward of demand during the pandemic as well as some project deferral could impact demand into 2024. As we consider these influences on home improvement demand, we are planning for a year of continued moderation but with slightly less pressure to comp sales than what we faced in fiscal 2023.
Our fiscal 2024 outlook is for total sales growth to outpace sales comp with sales growth of approximately positive 1% and comp sales of approximately negative 1% compared to fiscal 2023. Total sales growth will benefit from a 53rd week as well as from the acquisitions we made and the new stores we opened in fiscal 2023 and the stores we plan to open in fiscal 2024. We expect the 53rd week will contribute approximately $2.3 billion in sales. Our gross margin is expected to be approximately 33.9%, an increase of approximately 50 basis points compared to fiscal 2023. This primarily reflects a lower product and transportation cost environment relative to fiscal 2023 as well as benefits from a portion of the approximately $500 million in reduced fixed costs that we will realize in fiscal 2024.
Further, we expect operating margin of approximately 14.1%. This reflects deleverage from sales and pressure from targeted incentive compensation as we are overlapping lower incentive compensation paid than planned in 2023. This will be partially offset by the benefits from the approximately $500 million in fixed costs that we will realize in fiscal 2024 in both cost of goods sold and operating expenses. Our effective tax rate is targeted at approximately 24.5%. We expect net interest expense of approximately $1.8 billion. Our diluted earnings per share percent growth is targeted to be approximately 1% compared to fiscal 2023, with the extra week contributing approximately $0.30.
We plan to continue investing in our business with capital expenditures of approximately 2% of sales on an annual basis. After investing in our business and paying our dividend, it is our intent to return excess cash to shareholders in the form of share repurchases. We believe we have positioned ourselves to meet the needs of our customers in any environment. The investments we've made in our business have enabled agility in our operating model. As we look forward, we will continue to invest to strengthen our position with our customers, leverage our scale and low-cost position to drive growth faster than the market and deliver shareholder value.
Thank you for your participation in today's call. And Christine, we are now ready for questions.
