Kevin S. Wampler
Chief Financial Officer at Dollar Tree
Thanks, Mike, and good morning. For the quarter, consolidated net sales increased 4.6% to $7.08 billion, comprised of $3.92 billion of Dollar Tree, and $3.16 billion of Family Dollar. Enterprise same-store sales increased 2.5% as we cycled a 4.9% increase from a year ago, representing a 70 basis point improvement from Q3 to 7.4% on a two-year stacked basis. Cost for the Dollar Tree segment increased 3.1%. Family Dollar same-store sales increased 1.7% cycling a strong 8.1% increase from last year.
On a two-year stack basis, Dollar Tree comps increased 5.5%, which was a 90 basis point improvement from Q3, and Family Dollar increased 9.8%, which was a 70 basis point improvement from Q3. Dollar Tree's comp was comprised of a 6% increase in average ticket, partially offset by a 2.8% decline in traffic. Family Dollar experienced a 4.6% increase in average ticket, partially offset by a 2.7% decline in traffic.
Gross profit was $2.14 billion for the quarter. Gross margin was 30.2% compared to 31.8% in the prior year's quarter. Gross profit margin for the Dollar Tree segment declined 50 basis points to 35.6% when compared to the prior year's quarter. Factors impacting the segments gross margin, performance included, merchandise cost including freight increased 110 basis points, driven by higher freight costs, partially offset by increased initial mark on and increased sales of higher margin discretionary merchandise. This increase was partially offset by shrink that improved 30 basis points related to favorable inventory results and a decrease in the shrink accrual rate.
Distribution costs improved approximately 20 basis points resulting primarily from lower COVID-19 related expenses and sales leverage, partially offset by higher hourly wages and occupancy cost decreased approximately 10 basis points, as a result of the leverage from the comp sales increase in the quarter. Gross profit margin for the Family Dollar segment declined 320 basis points to 23.4% in the fourth quarter.
Year-over-year Delta included the following, merchandise cost including freight increased 220 basis points related to higher freight costs and an unfavorable sales mix, partially offset by higher initial mark-on. Markdowns increased 90 basis points, primarily related to our recent product recall in our Arkansas distribution center and 404 Family Dollar stores.
Consolidated selling, general and administrative expenses increased 40 basis points to 22.1% of total revenue compared to 21.7% in Q4 last year. For the fourth quarter, the SG&A rate for the Dollar Tree segment as a percentage of total revenue increased 50 basis points to 20.6% when compared to the prior year's quarter. Other SG&A increased approximately 50 basis points resulting from higher card transaction fees and operating taxes along with marketing and store supply costs associated with the transition to the $1.25 price point.
Payroll costs increased 10 basis points resulting primarily from higher store hourly payroll costs due to minimum wage increases and higher healthcare costs, partially offset by lower incentive compensation. And depreciation cost decreased 15 basis points, primarily due to lower store-impairment write-offs and leverage due to the increase in comp store sales. For Family Dollar, the fourth quarter SG&A rate as a percentage of total revenue increased 10 basis points to 20.7% compared to 20.6% in the prior year's quarter.
Other SG&A expense increased 25 basis points, primarily due to lower miscellaneous income, an increase in card transaction fees, an increase in insurance costs related to general liability claims. Depreciation and amortization expense increased 15 basis points due to higher store asset impairment charges and expenditures associated with the store renovation program. Store facility costs increased 5 basis points, primarily due to higher repairs and maintenance expenses, including snow removal, partially offset by lower telecommunication expenses.
Payroll expenses improved 35 basis points, primarily due to lower incentive compensation and field management vacancies, partially offset by higher store hourly payroll resulting from higher labor rates. Corporate support and other expenses as the percentage of total revenue were flat when compared to the prior year's quarter at 1.4%.
Operating income was $578.8 million or 8.2% of total revenue in the fourth quarter. Non-operating expenses totaled $79.6 million comprised primarily of net interest expense including debt extinguishment costs of $46.5 million associated with our debt refinancing in the quarter. Effective tax rate was 9% compared to 22.3% in the prior year's fourth quarter resulting primarily from a deferred tax benefit related to state entity restructuring.
Companies had net income of $454.2 million or $2.01 per diluted share. This compared to net earnings of $502.8 million or $2.13 per diluted share in the prior year's quarter. Combined cash and cash equivalents at year end totaled $984.9 million compared to $1.42 billion at the end of fiscal 2020. Outstanding debt as of January 29 was $3.45 billion.
For the year, the company repurchased $950 million in shares at an average price of $103.75. The company did not repurchase shares during the fourth quarter as our Board is engaged in discussions with Mantle Ridge. We currently have $2.5 billion remaining on our share repurchase authorization. Compared to the prior year, inventory levels increased 39% at Dollar Tree and 17% at Family Dollar. The higher levels of inventory are comprised of significant increases in goods on the water year-over-year as we rebuild inventory levels, as well as increased capitalized freight cost based on much higher rates during the year. We do not anticipate any additional material inventory markdowns related to the recent Family Dollar voluntary product recall.
Capital expenditures were $271.6 million in the fourth quarter versus $191.8 million in Q4 of last year. For fiscal 2022, we expect that consolidated capex will be approximately $1.3 billion, which will be focused on 590 new stores, consisting of 400 Family Dollar and 190 Dollar Tree Stores, 1,500 Dollar Tree plus additions and 800 Family Dollar H2 renovations, with addition of our replacement of frozen and refrigerated capability to select Dollar Tree and Family Dollar stores, supply chain construction and upgrades and information technology system projects.
Depreciation and amortization totaled $188.7 million for Q4 compared to $182.9 million in the fourth quarter last year. For fiscal 2022, we expect consolidated depreciation and amortization to be approximately $750 million.
Our initial outlook for fiscal 2022 includes the following assumptions. For same-store sales, for the enterprise, we are forecasting low-to mid-single-digit positive comps for the year. Considerations for 2022 include the following. The company incurred approximately $33.5 million in COVID-19 related costs in fiscal 2021. We expect these costs to be minimal in fiscal 2022. We will be cycling a third round of stimulus check that totaled an estimated $386 billion in March of 2021 and later in the year, we will be cycling the monthly advanced Child Tax credit payments that began in July of 2021.
We expect continued pressure on store and DC payroll based on competitive markets, states increasing minimum wages, unemployment levels and completing the company's many initiatives. We expect to incur more than $165 million in store minimum wage changes and market adjustments. In addition, we are investing more than $30 million in DC hourly wages. We continue to partially offset these average hourly rates -- rate increases through productivity and efficiency initiatives.
Import and domestic freight will present cost pressures due to the annualization of fiscal 2021 rates in the first half of 2022. In addition, diesel fuel prices are expected to be significantly higher in 2022. We cannot predict future currency fluctuations. So we have not adjusted our outlook for the currency rate changes.
Net interest expense is expected to be approximately $33 million for Q1 and approximately $129 million for fiscal 2022. We estimate consolidated net sales for the first quarter will range from $6.63 billion to $6.78 billion based on a low-single-digit increase in same-store sales for the combined enterprise.
Diluted earnings per share estimated to be in the range of $1.95 to $2.10. Consolidated net sales for full fiscal 2022 are expected to range from $27.22 billion to $27.85 billion. The company estimates diluted earnings per share will range from $7.60 to $8, which at the high end implies a consolidated operating income margin of 9%. Our outlook assumes a tax rate of 24.3% for the first quarter and 24.1% for fiscal 2022.
Our weighted average diluted share counts are assumed to be 226.5 million shares for Q1 and 226.7 million shares for the full year. Our outlook does not include any share repurchases. And as previously mentioned, we currently have $2.5 billion remaining on our existing share repurchase authorization.
I'll turn the call back over to Mike.
