Quick answer
Dividend yield is a share's annual dividend divided by its current price, times 100, so a $65 share paying $0.50 a quarter ($2.00 a year) yields 3.08%. A yield rises when the price falls as well as when the dividend rises, so a high yield on its own does not show whether earnings cover the dividend; the payout ratio compares the two.
What dividend yield actually measures
Dividend yield is the annual cash a share pays you, expressed as a percentage of what that share costs today. It's the same idea as the interest rate on a savings account, except the "rate" isn't guaranteed — a board of directors can raise, cut, or eliminate it at any time.
Everything else on this page is that one formula run in three directions: solve for yield when you know the price and dividend, solve for income when you know the yield and the amount you're investing, or solve for yield on cost when the "price" you plug in is what you originally paid rather than today's quote.
Trailing vs. forward yield
Trailing yield adds up the actual cash dividends paid over the last 12 months and divides by the current price — it describes the past. Forward yield takes the most recently declared payment (usually the latest quarterly dividend) and annualizes it — a projection of what the next 12 months will pay if nothing changes. For a stable, boring dividend payer the two numbers are nearly identical. They pull apart right after a raise, a cut, or a special one-off dividend, because the trailing figure still includes the payments made before the change. Corporate Finance Institute (11 December 2019) says the trailing figure suits a company whose payments differ significantly during the year, and the forward figure one that plans a regular payout for the next 12 months.
The high-yield trap
Yield has two ways to go up: the dividend can rise, or the price can fall. A stock that halves in price on an unchanged payout doubles its yield, so a high yield can come from a low price as easily as from a large dividend. The yield trap is the name given to a stock whose high yield may hide a dividend its finances cannot sustain. The Motley Fool's explainer (updated 2 March 2025) describes it that way and says yield traps often occur when a stock's price is dropping. An MSCI blog post of 25 October 2019 on screening for yield traps (its screens were tested on the MSCI World Index) says that in periods of general economic distress share prices can fall a long way in a short time, and that trailing yields can then spike artificially, only to drop abruptly once dividends are reduced or discontinued. It adds that during and after the global financial crisis many of the banking stocks that initially had the highest trailing yields stopped paying dividends for a significant time. It sets no yield cut-off, and neither does this page: the payout-ratio section below sets out what three other pages say instead.
Payout ratio: the one-line sanity check
The payout ratio is the share of earnings a company actually pays out as dividends: dividends paid ÷ net income. It shows how much of earnings the dividend takes, which a yield cannot. The table sorts what three pages say about it; none of the markers is this calculator's own, and the pages do not agree with one another.
| Payout ratio | What the cited pages say |
|---|---|
| Below 0% (a net loss) | Liberated Stock Trader: a negative ratio means the company reported a loss but still paid dividends. |
| 0% to 60% | The Motley Fool: a safe payout ratio has historically been in the 30% to 55% range. Dividend.com sets its first marker above 60%. |
| Over 60% to 80% | Dividend.com: any ratio above 60% should lead an investor to look deeper into the company's financials. |
| Over 80% to 100% | Dividend.com: ratios above 80% can be a red flag. |
| Over 100% | Dividend.com: not sustainable in the long run. The Motley Fool: be especially cautious. Liberated Stock Trader: a high ratio, typically one above 100%, may indicate a company is returning more money to shareholders than it earns, which might be unsustainable in the long term. |
Every row is one page's statement, not a verdict from this calculator, and the ranges together cover every possible ratio. Liberated Stock Trader says stable sectors such as utilities typically have higher payout ratios, and the SEC's Investor.gov says most REITs pay out at least 100 percent of their taxable income (a different base from net income). Liberated Stock Trader says analysts must compare a company's payout ratio with industry averages to make a meaningful analysis.
Yield on cost, explained
Yield on cost (YOC) swaps the denominator: instead of dividing the current dividend by today's price, you divide it by what you paid when you bought. If a stock's dividend grows over the years while you keep holding, your YOC climbs with the dividend, while the yield a new buyer sees depends on today's price. YOC shows how much a long-held position's income has grown relative to what you paid. It does not describe what a new buyer gets, since a new buyer pays today's price, not yours.
Worked example 1 — finding the yield
A share trades at $65 and pays $0.50 per quarter. Annualized: $0.50 × 4 = $2.00 a year. Yield = $2.00 ÷ $65 × 100 = 3.08%, which this calculator puts in its 2% to under 4% group. For reference, State Street's page for the SPDR S&P 500 ETF Trust listed the S&P 500's index dividend yield as 1.09% on 8 October 2026.
Worked example 2 — income from an investment
You're putting $50,000 into a fund yielding 4%. Annual income = $50,000 × 4% = $2,000. Monthly = $2,000 ÷ 12 = $166.67; quarterly = $2,000 ÷ 4 = $500.00. This assumes the yield holds steady and you spend the dividends rather than reinvest them — reinvesting instead would compound the position, which is what the DRIP calculator models.
Worked example 3 — yield on cost, and a payout ratio over 100%
You bought a stock years ago at $40 a share. It now pays $2.40 a year and trades at $80. Your yield on cost is $2.40 ÷ $40 = 6.0%, while the current market yield is $2.40 ÷ $80 = 3.0% — the price doubled and the dividend grew, so your personal income return on the money you actually spent is double what a new buyer gets today. That is what yield on cost measures: the dividend relative to what you paid.
Now compare an invented stock with a very high yield: priced at $10 and paying $1.20 a year against earnings per share of only $0.90. The yield is $1.20 ÷ $10 = 12.0%, but the payout ratio is $1.20 ÷ $0.90 = 133%, meaning the dividend is a third more than the earnings per share. Dividend.com, the Motley Fool and Liberated Stock Trader each treat a payout ratio over 100% as unsustainable or a reason for caution (see the table above). The numbers describe this made-up stock's dividend and earnings; they do not say what it will do.
Practical guidance
- Yield is one number. It does not show whether earnings cover the dividend; the payout ratio compares the two (see the table above).
- Trailing and forward yield differ after a dividend change. The trailing figure still includes payments made before the change; the forward figure annualizes the latest payment.
- Yield on cost describes your own history. A new dollar buys at today's price, so it earns today's yield, not your yield on cost.
- Payout ratios are read within a sector. Liberated Stock Trader says stable sectors such as utilities typically have higher payout ratios, and the SEC's Investor.gov says most REITs pay out at least 100 percent of their taxable income.
- Yield is one part of total return. Total return adds the dividends received to any change in the price.

FAQ
What counts as a good dividend yield?
No single yield counts as good or bad on its own. This calculator sorts yields into four groups of its own by size (under 2%, 2% to under 4%, 4% to under 8%, and 8% or more); the cut-offs are this calculator's own and are not taken from a source. For reference, State Street's pages for the ETFs that track these indexes listed index dividend yields on 8 October 2026 of 1.09% for the S&P 500, 3.09% for its Utilities Select Sector Index, 3.64% for its Real Estate Select Sector Index and 1.21% for its Communication Services Select Sector Index, each the weighted average of the index holdings' indicated annual dividend divided by price. Those figures change every day and say nothing about any one stock.
Why can a very high dividend yield be misleading?
Yield is dividend divided by price, so it rises two ways: the dividend goes up, or the price falls. A stock trading at half its former price shows double the yield on an unchanged payout. The Motley Fool's explainer on yield traps, updated 2 March 2025, describes a yield trap as a stock paying an exceptionally high dividend that its finances may not be able to sustain, and says yield traps often occur when a stock's price is dropping. An MSCI blog post of 25 October 2019 on screening for yield traps (tested on the MSCI World Index) says that in periods of general economic distress share prices can fall a long way in a short time, and that trailing yields can then spike artificially, only to drop abruptly once dividends are reduced or discontinued. It adds that during and after the global financial crisis many of the banking stocks that initially had the highest trailing yields stopped paying dividends for a significant time. It sets no yield cut-off.
What's the difference between trailing and forward dividend yield?
Trailing yield uses the dividends actually paid over the last 12 months divided by the current price — it describes the past. Forward yield annualizes the most recently declared payment (for example, the latest quarterly dividend times four) divided by the current price — it's a projection. The two match for a stable payer with no recent change. They diverge right after a dividend increase, cut, or suspension, because the trailing figure still includes payments made before the change.
What does yield on cost actually tell me?
Yield on cost (YOC) is the current annual dividend divided by what you originally paid per share, not the current price. It only means something to you, the existing holder — a new buyer today gets the current yield, not your YOC, because they're paying today's price. YOC compares the dividend with what you paid; it does not show what a new purchase would yield.
How do I check whether a dividend is sustainable?
The payout ratio compares dividends paid with earnings: dividends divided by net income. Sources put their markers in different places. Dividend.com says a ratio above 60% should lead an investor to look deeper into the company's financials, above 80% can be a red flag, and over 100% is not sustainable in the long run. The Motley Fool says a safe payout ratio has historically been in the 30% to 55% range and urges particular caution above 100%. Liberated Stock Trader says a high ratio, typically one above 100%, may indicate a company is returning more money to shareholders than it earns, which might be unsustainable in the long term, and that stable sectors such as utilities typically have higher ratios, and the SEC's Investor.gov says most REITs pay out at least 100 percent of their taxable income.
Is dividend yield enough on its own?
No. A yield is a dividend divided by a price at one moment. By itself it does not show whether earnings cover the dividend, how the dividend has changed, or what the price will do. Total return adds the dividends received to any change in the price.
