Yield on Cost: Understanding How Your Dividend Income Grows Over Time

Yield on Cost (YOC) is a valuable metric for investors who focus on dividend-paying stocks. Unlike the regular dividend yield, which is calculated based on the current market price of a stock, Yield on Cost measures the dividend income relative to the original purchase price you paid for the shares. This metric helps investors understand how much income they are earning compared to their initial investment, highlighting the power of dividend growth and compounding returns over time.

Yield on Cost is particularly useful for long-term investors who hold dividend stocks that increase their payouts regularly. While the market price of a stock fluctuates daily, your original cost per share remains fixed. As companies raise dividends, your YOC improves, even if the stock price doesn’t move much—or even falls. This makes Yield on Cost a preferred measure for dividend growth investors who want to track the effectiveness of their investment strategy.

Formula: Yield on Cost = (Annual Dividend per Share / Original Purchase Price per Share) x 100

For example, imagine you bought 100 shares of a company at $50 per share, so your total investment was $5,000. At the time of purchase, the company paid an annual dividend of $2 per share, which means your initial dividend yield was 4% ($2 ÷ $50 x 100). After five years, suppose the company increases its dividend to $3.50 per share. Even if the stock price has risen to $70 or dropped to $45, your Yield on Cost remains based on your original $50 purchase price. Your new YOC is ($3.50 ÷ $50) x 100 = 7%. This shows that your income is growing relative to your initial investment, regardless of current market price fluctuations.

A real-life example can be seen with companies like Coca-Cola (KO), which has a long history of increasing dividends. An investor who purchased Coca-Cola shares years ago at $40 with a dividend yield of 3% might now receive a yield on cost of over 6%, thanks to consistent dividend growth. This contrasts with the current dividend yield, which might be lower or higher depending on the current stock price.

Common misconceptions often arise around Yield on Cost. One mistake is confusing YOC with the current dividend yield. Yield on Cost does not reflect the market value or the immediate return if you were to sell the stock today. Instead, it shows the income efficiency of your original investment. Another misconception is assuming that a higher YOC always means a better investment. While a growing YOC signals increasing dividend income, investors should also consider the sustainability of dividends, the company’s financial health, and overall market conditions.

Investors also frequently ask, “How is Yield on Cost different from dividend yield?” and “Why is Yield on Cost important for dividend investors?” Yield on Cost provides insight into how dividends have increased relative to your initial investment, which can help in retirement planning or assessing income growth. On the other hand, dividend yield reflects the return on current market value, useful for comparing investment opportunities in real time.

In summary, Yield on Cost is a powerful tool for dividend growth investors who want to track their income relative to the original amount invested. It emphasizes the benefits of dividend reinvestment and compounding over time but should be used alongside other metrics to assess the overall quality and sustainability of investments.
