Quick Answer: Yield on cost vs dividend yield comes down to the price used in the formula. Yield on cost compares today’s annual dividend to your original purchase price, while dividend yield compares the annual dividend to the stock’s current market price. Use yield on cost to understand how your past dividend growth worked out, but use current dividend yield to evaluate today’s buy, hold, or sell decision.
A dividend is a portion of a company’s profit paid to shareholders. Public companies that pay dividends usually do so on a schedule, although special or extra dividends can happen at other times. For dividend investors, the confusing part is that the same stock can show a high yield on cost and a much lower current dividend yield at the same time.
Yield on Cost vs Dividend Yield: The Core Difference
Yield on cost measures the dividend income you are receiving compared with what you originally paid for the investment. Dividend yield measures the dividend income a buyer would receive compared with the stock’s current market price.
That difference matters because yield on cost is personal to you. Two investors can own the same stock and have different yields on cost because they bought at different prices. Dividend yield is market-based. Everyone looking at the stock today sees roughly the same current yield, aside from data-source timing differences.
The practical takeaway is simple: yield on cost tells a story about your past purchase price; dividend yield helps analyze today’s opportunity.
Yield on Cost Formula
The yield on cost formula is:
Yield on cost = annual dividend per share ÷ original cost per share
If you bought a stock at $40 per share and it now pays $2.40 per share annually:
$2.40 ÷ $40 = 0.06, or 6% yield on cost
That means you are now receiving annual dividend income equal to 6% of your original purchase price.
Yield on cost can be useful because it shows how dividend growth has improved your income return on the dollars you originally invested. If you bought a company years ago at a low price and the company raised its dividend repeatedly, your yield on cost may look impressive.
The limitation is that your original price is no longer the price available to new investors. It also may not reflect the best use of your current capital.
Dividend Yield Formula
The dividend yield formula is:
Dividend yield = annual dividend per share ÷ current share price
Charles Schwab explains dividend yield as annual dividend payouts divided by current share price, and it warns that a high or rising yield can be a bad sign if the yield is rising mainly because the stock price is falling. Review Schwab’s explanation of dividend yield for additional context.
Using the same stock from above, suppose the current share price is $80 and the annual dividend is $2.40:
$2.40 ÷ $80 = 0.03, or 3% current dividend yield
So the same stock can have:
- 6% yield on cost for the investor who bought at $40
- 3% dividend yield for someone evaluating the stock at $80 today
That is not a contradiction. The two metrics answer different questions.
Side-by-Side Example
Assume you bought 250 shares at $40 each, for a total original investment of $10,000. The stock now trades at $80 and pays $2.40 per share annually.
| Metric | Calculation | Result | What It Means |
|---|---|---|---|
| Original investment | 250 shares × $40 | $10,000 | Your original cost |
| Current market value | 250 shares × $80 | $20,000 | What the position is worth now |
| Annual dividend income | 250 shares × $2.40 | $600 | Current annual income |
| Yield on cost | $600 ÷ $10,000 | 6.0% | Income return on your original cost |
| Current dividend yield | $600 ÷ $20,000 | 3.0% | Income return on today’s market value |
This example shows why yield on cost feels rewarding. You are collecting $600 a year on an original $10,000 investment. But the current dividend yield shows the opportunity cost: your $20,000 position is producing $600 per year, or 3%.
If another investment of similar quality, risk, and tax treatment could produce a sustainable 4% or 5%, the high yield on cost alone should not end the analysis.
Yield on Cost vs Current Yield: What Each Metric Answers
Use yield on cost when asking:
- Did my dividend income grow since I bought this stock?
- How much income is my original investment producing now?
- Has dividend growth rewarded my patience?
- Is this stock contributing meaningfully to my long-term income plan?
Use current dividend yield when asking:
- Would I buy this stock today?
- Is the stock’s income attractive at the current price?
- Is the yield unusually high because the price has fallen?
- How does this stock compare with alternatives today?

Why Yield on Cost Can Be Useful
Yield on cost is useful as a personal progress metric. It can show whether a dividend growth strategy actually increased your income over time.
For example, suppose a stock cost $50 and paid a $2 annual dividend when you bought it. Your starting dividend yield was 4%.
If the dividend grows for 10 years, your yield on cost changes like this:
| Annual Dividend Growth Rate | Dividend After 10 Years | Yield on Original $50 Cost |
|---|---|---|
| 0% | $2.00 | 4.0% |
| 3% | $2.69 | 5.4% |
| 5% | $3.26 | 6.5% |
| 7% | $3.93 | 7.9% |
| 10% | $5.19 | 10.4% |
This is the strongest case for yield on cost. It helps you see the long-term effect of dividend growth on your original dollars.
It also encourages patience. If a company keeps raising its dividend because earnings and cash flow are growing, your income can rise without you adding new money to that position.
Why Yield on Cost Can Be Misleading
Yield on cost becomes misleading when investors use it to justify holding a stock automatically.
A high yield on cost does not mean the stock is still attractive today. It may simply mean you bought years ago at a much lower price. The current market value of the position is what you could sell and redeploy, so current yield and future return potential still matter.
Here are common traps:
| Situation | Yield on Cost Says | Current Dividend Yield Says | Risk |
|---|---|---|---|
| Stock price rose sharply, dividend rose slowly | “My yield on cost is strong” | “Current income is low” | Capital may be tied up inefficiently |
| Stock price fell sharply, dividend unchanged | “My income is still okay” | “Yield is unusually high” | Market may expect a dividend cut |
| Dividend was cut after years of growth | “My original yield used to be great” | “Current income has weakened” | Past growth no longer protects income |
| Better alternative exists | “I have a great yield on cost” | “Another investment may pay more today” | Opportunity cost may be ignored |
A rising dividend yield can be caused by a falling share price, not improving business quality. Schwab makes the same warning: if yield rises while the dividend stays the same, the stock price had to fall, which is often not a good sign. Review Schwab’s discussion of rising dividend yields for more context.
That is why dividend investing metrics should include payout ratio, earnings stability, cash flow, debt, dividend growth, valuation, and total return — not yield alone.
Should You Sell a Stock With a High Yield on Cost?
You should not sell only because another stock has a higher current dividend yield, but you also should not hold only because your yield on cost is high.
Use this decision test:
- Would you buy the same stock today at the current price?
- Is the current dividend safe and supported by cash flow?
- Is the company still growing earnings or free cash flow?
- Is the current dividend yield competitive with similar-quality alternatives?
- Would selling create taxable capital gains?
- Would switching improve income after taxes, not just before taxes?
- Would the new investment add risk, concentration, or lower dividend quality?
For example, suppose you bought a stock at $40 and it now trades at $80. It pays $2.40 annually, giving you a 6% yield on cost but only a 3% current dividend yield.
If you sell one share at $80 with a $40 cost basis and assume a simplified 15% capital-gains tax on the $40 gain, the tax would be $6. That leaves $74 to reinvest.
If a comparable alternative yields 4.5%, the reinvested $74 would produce:
$74 × 4.5% = $3.33 per year
Your current stock produces $2.40 per year. In this simplified example, switching could increase annual income even after the assumed tax. But if the alternative is riskier, less diversified, or less likely to grow, the higher income may not be worth it.
Taxes can change the answer. The IRS says ordinary dividends are included in ordinary income, while qualified dividends may qualify for lower capital-gain tax rates. The IRS also says Form 1099-DIV is generally issued by payers for distributions of at least $10. Review IRS Topic No. 404 on dividends for current guidance.
How Reinvested Dividends Affect Yield on Cost
Reinvested dividends can complicate yield on cost because each reinvestment usually buys additional shares at a new price.
There are two common ways investors think about it:
| Method | How It Works | Best Use |
|---|---|---|
| Original-lot yield on cost | Compares current dividend to the price of the original shares | Simple long-term tracking |
| Average-cost yield on cost | Compares total current dividend income to total cost basis across all lots | Better for reinvested dividends and repeated purchases |
If you reinvest dividends over many years, your cost basis may include multiple share lots bought at different prices. That means a single “yield on cost” number can hide a lot of detail.
For most investors, average-cost yield on cost is cleaner:
Portfolio yield on cost = current annual dividend income ÷ total cost basis
This is especially useful if you use dividend reinvestment, dollar-cost averaging, or recurring purchases. The Finance Orbit’s dollar-cost averaging guide explains how regular investing can build positions over time without depending on one purchase price.
Dividend Yield, Ex-Dividend Dates, and Timing
Dividend yield is based on annual dividend income and current price, but actually receiving the next dividend depends on timing.
Investor.gov explains that investors need to look at the record date and ex-dividend date. If you buy a stock on or after the ex-dividend date, you generally do not receive the next dividend payment. Review the Investor.gov ex-dividend date guide before timing purchases around dividend dates.
This matters because buying right before a dividend does not create free money. Stock prices may adjust around dividend dates, and taxes may still apply in a taxable account.
Use yield metrics for analysis, not for short-term dividend capture. A quality dividend investment should make sense even after the next dividend payment date has passed.
Which Metric Matters More?
For new money, current dividend yield matters more than yield on cost. You are investing at today’s price, not yesterday’s price.
For evaluating your past decision, yield on cost can be useful. It shows how much income your original capital is now producing.
For deciding whether to hold, sell, or buy more, use both — but do not let yield on cost dominate the decision. The better question is:
What is the best risk-adjusted use of this money today, after taxes and expected dividend growth?
If the stock still has strong fundamentals, reasonable valuation, growing dividends, and a role in your portfolio, a high yield on cost can be a satisfying sign of patience. If the business has weakened or better alternatives exist, yield on cost can become an emotional anchor.

Frequently Asked Questions
What is the difference between yield on cost and dividend yield?
Yield on cost uses your original purchase price, while dividend yield uses the current share price. That means yield on cost is personal to your purchase history, while dividend yield reflects what the stock offers at today’s market price.
What is the yield on cost formula?
The yield on cost formula is annual dividend per share divided by original cost per share. If you paid $40 for a stock and it now pays $2.40 annually, your yield on cost is 6%.
What is the dividend yield formula?
The dividend yield formula is annual dividend per share divided by current share price. If a stock pays $2.40 annually and trades at $80, its current dividend yield is 3%.
Is yield on cost useful?
Yes, yield on cost is useful for tracking how dividend growth has improved income on your original investment. It is less useful for deciding whether to buy more shares today because today’s decision depends on the current price and future prospects.
Why can yield on cost be misleading?
Yield on cost can be misleading because it ignores the current market value of your investment. A high yield on cost may make a stock feel better than it is, even if the current yield, business quality, or future dividend growth no longer compares well with alternatives.
Should I sell a stock with a high yield on cost?
No, you should not sell only because of yield on cost. Compare the company’s fundamentals, current dividend yield, dividend safety, tax impact, and available alternatives. A high yield on cost is one input, not a complete sell-or-hold decision.
Is current dividend yield better than yield on cost?
Current dividend yield is better for comparing today’s investment opportunities. Yield on cost is better for reviewing how your original investment has performed as an income source. Most buy, sell, and rebalance decisions should lean more heavily on current yield and expected future return.
Use Both Metrics, but Let Today’s Facts Lead
Yield on cost can be motivating because it shows what patient dividend growth can do over time. Dividend yield is more practical because it shows what your capital is earning at the current market price.
The best dividend investors do not choose one metric and ignore the other. They use yield on cost to understand the past, current dividend yield to analyze the present, and business fundamentals to judge the future.
