Dividends combined with capital appreciation provide investors with a total return. However, it's vital to ensure a company can afford to continue making payments. Fortunately, it's a straightforward calculation for the year-ahead dividend payments, although you'll have to make certain assumptions.

Home Depot (HD -0.58%), the world's largest home-improvement retailer, has been a reliable dividend provider. It has made payments for about 35 straight years.

How much will the company pay in dividends next year? And can it afford it? It's time to do some basic math.

Calculating the payout

Home Depot currently pays $2.25 per share in a quarterly dividend. The share count was 993.3 million and 991.6 million at the end of the first and second quarters, respectively. That takes into account share repurchases and the timing of stock-based compensation to employees.

For the first six months of the current fiscal year, covering the period that ended on July 28, the company's dividends totaled $4.5 billion. Fortunately, the $9.3 billion in free cash flow easily covered the payment.

What about calendar 2025's dividends? The board of directors has raised dividends annually since 2010, including a sharp 7.7% boost last year.

Therefore, it seems reasonable to assume a 5% increase that will likely start with December's payout. That works out to a $2.36 quarterly rate. Assuming the share count remains flat, 2025's dividends would total $9.4 billion.

While sales have slumped due to macroeconomic factors such as weary consumers and sluggish home sales, the company has maintained profitability. Same-store sales fell 3.3% in the second quarter, but adjusted diluted earnings per share were essentially flat: $4.67 versus $4.68 a year ago.

But home sales will eventually rebound, and owners will perform major renovations. It's a question of timing, but when it happens, Home Depot will remain in a prime position to benefit. In the meantime, shareholders can enjoy the 2.3% dividend yield, roughly 1 percentage point higher than the S&P 500.
