What is dividend payout ratio?
Dividend payout ratio is dividends per share divided by earnings per share. It tells you what share of a company’s profit is paid out to shareholders as dividends — how much of each dollar earned goes back to owners, and how much stays in the business.
A ratio of 40.00% means 40 cents of every dollar of earnings is paid out and 60 cents is kept. The kept part funds growth, pays down debt, or builds a buffer.
The dividend payout ratio formula
Dividend payout ratio = dividends per share ÷ earnings per share × 100. Retained per share = earnings per share − dividends per share. Retention ratio = 100% − payout ratio. Two more formulas turn the ratio around: dividends per share needed at a target = target ratio × earnings per share, and earnings per share allowed at a target = dividends per share ÷ target ratio. Total dividends divided by net income gives the same answer.
Step 1: work out the dividends per share
Dividends per share is what the company pays out per share each year: total dividends paid in the year divided by the number of shares, or the per-share dividend straight from the company’s dividend history. In our example it is $2.00. Use the full year, not one quarter, and the same year for both figures.
Step 2: work out the earnings per share
Earnings per share is what the company earns per share — net income divided by the number of shares. Try the earnings per share calculator if you only have the totals. In our example it is $5.00. Use the same year as the dividends, and watch for one-off earnings — a single asset sale can make earnings look far bigger than the business really earns.
Step 3: divide the dividends per share by the earnings per share
Divide $2.00 by $5.00 and multiply by 100: $2.00 ÷ $5.00 = 0.40, and 0.40 × 100 = 40.00%. That is the whole calculation. The retained per share is $5.00 − $2.00 = $3.00 — 60.00% of earnings stays in the business. Try it on the dividend payout ratio calculator and check the answer against your own arithmetic.
Three worked examples
Example 1 — the main example. $2.00 of dividends per share on $5.00 of earnings per share: $2.00 ÷ $5.00 × 100 = 40.00%. Retained per share: $5.00 − $2.00 = $3.00 (60.00% retained). For a 50.00% target: dividends per share needed is 50.00% × $5.00 = $2.50, and earnings per share allowed is $2.00 ÷ 50.00% = $4.00.
Example 2 — the rounding trap. $4.00 of dividends on $6.00 of earnings: $4.00 ÷ $6.00 × 100 = 66.67% — but the unrounded ratio is 66.6667%, so it displays as 66.67% while sitting below the 66.67% target.
Example 3 — the low end. $2.00 of dividends on $6.00 of earnings: $2.00 ÷ $6.00 × 100 = 33.33% — the unrounded ratio is 33.3333%, so it displays as 33.33% while sitting above 33.33% unrounded.
One reverse to check your answer
Work it backwards: the smallest whole-cent dividends per share for the ratio to reach 50.00% is $2.50 — at $2.50 the ratio is 50.00%, exactly 50.00%, and at $2.49 it is 49.80%. The largest whole-cent earnings per share for the ratio to stay at or above 50.00% is $4.00 — at $4.00 the ratio is 50.00%, and at $4.01 it is 49.88% (unrounded 49.8753%). If your answer does not survive the reverse, the arithmetic is wrong.
What a good ratio looks like
0% — growth companies. A company that pays no dividend at all reinvests everything. Young growth companies commonly pay nothing, and a 0% ratio is not a failure.
30–50% — mature companies. The steady middle: enough to reward shareholders and enough kept to keep growing. A 40.00% ratio sits here.
Above 100% — unsustainable. The company paid out more than it earned, possible for a year or two from reserves or borrowing, but it cannot last. A rising ratio on falling earnings is the classic dividend-cut warning.
The 66.6667% rounding trap
The ratio is displayed to two decimals, half-up — and the display can lie by a hair. $4.00 of dividends on $6.00 of earnings is 66.6667% unrounded: it displays as 66.67%, but it sits below the 66.67% target — so $4.00 is not enough to reach 66.67%, and the smallest whole-cent dividends per share that reaches it is $4.01 (66.8333% unrounded, displaying as 66.83%). Print the unrounded ratio when the answer is close to a round target — the calculator does.
What a negative ratio means
At −$5.00 of earnings per share, $2.00 of dividends gives a ratio of −40.00%. Negative earnings means the company lost money yet still paid a dividend — a data problem, not a real payout. The calculator shows the negative figure with a note, never hides it.
What if the earnings per share is zero?
At $0 of earnings per share the ratio is undefined — there are no earnings to pay from, so there is nothing to divide by. The calculator shows the ratio as undefined with that note, never a crash and never a made-up number. No retained-per-share figure is printed for that case, because retained is meaningless with no earnings.
The 120.00% over-100% case
$6.00 of dividends per share on $5.00 of earnings per share is 120.00% — the company paid out more than it earned, and the retained per share is −$1.00. Paying out more than the company earned is possible only from reserves or borrowing, and it cannot last. A ratio over 100% is the loudest warning the ratio gives.
How it differs from dividend yield
Dividend yield is dividends per share divided by the share PRICE — it tells you the income on the price you pay. The payout ratio is dividends per share divided by EARNINGS — it tells you whether the dividend is affordable. A share can have a high yield and a dangerous payout: the price fell, the yield rose, and the earnings cannot cover the dividend. Read both together — the dividend yield guide covers the yield side, and the dividend yield calculator works it out. It also differs from the price-to-earnings ratio — see the price-to-earnings ratio calculator — and from the operations ratios — see the operations ratios calculator.
The mistakes to avoid
Mixing years: dividends and earnings from different years answer nothing.
Using a one-off: a single asset sale can inflate earnings and shrink the ratio.
Trusting the display: print the unrounded figure when the answer is close to the target.
Ignoring buybacks: a 20% dividend plus buybacks can return more cash than a 40% dividend alone.
Reading a high ratio as generosity: a 90% payout with no growth keeps nothing to invest.
