What the payout ratio means

A company that earns a profit can do two things with it: hand some to shareholders as a dividend, or keep it in the business. The payout ratio is the share handed out; the retention ratio is the share kept. They sum to 100%.

The dividend yield post measured the dividend against the share price — what the investor receives per rupee invested. Payout measures it against profit — what the company chooses to distribute per rupee earned. Same dividend, two denominators, two different questions. Yield is about you. Payout is about the company’s strategy.

The formula

Payout ratio     =  Dividends / PAT   =  DPS / EPS

  PAT = profit after tax; DPS = dividend per share; EPS = earnings per share
Retention ratio  =  1 − Payout ratio

Sustainable growth rate  ≈  ROE × Retention ratio

The third line is why payout matters beyond the dividend cheque. If a company retains a fraction r of its profit and earns a return on equity of ROE on what it keeps, its equity — and, all else equal, its earnings — can grow at roughly ROE × r a year without borrowing more or issuing shares. This is the “sustainable” or “internal” growth rate, and it links three things this blog has covered separately: ROE, dividends, and the growth assumptions behind a DCF.

Worked example: Desi Bites Foods, FY25

From the case study, the year before the IPO:

 
FY25 PAT (₹ lakh) 209
FY25 dividend (₹ lakh) 84
Payout ratio = 84 / 209 40.2%
Retention ratio 59.8%
Per share: DPS ₹8.4 / pre-issue EPS ₹20.9 40.2%
FY25 ROE 34.0%
Sustainable growth = 34.0% × 59.8% ≈ 20.3%

Desi Bites kept about sixty paise of every rupee and earned 34% on its equity, so it could fund roughly 20% growth a year from retained profit alone. That’s a useful sanity check on the DCF, which assumed 18% revenue growth in FY26 — in range. It also explains why the company could have grown without the IPO, and why the capital allocation question of what to do with ₹1,600 lakh of fresh cash is a real one.

Worked example: Britannia Industries, FY25

DPS from the dividend yield post: ₹73.5, the dividend actually paid during FY25 (in August 2024). Strictly, that was the final dividend for FY24 (item 2 of the notice of Britannia’s 105th annual general meeting), so this is a trailing ratio — the dividend paid in FY25 divided by FY25 EPS. EPS and ROE from the audited FY25 results (year ended 31 March 2025). For illustration only.

 
DPS paid in FY25 (trailing) ₹73.5
FY25 EPS ₹90.45
Payout ratio = 73.5 / 90.45 81.3%
Retention ratio 18.7%
FY25 ROE 52.5%
Sustainable growth = 52.5% × 18.7% ≈ 9.8%

The final dividend recommended for FY25 — ₹75 a share, to be declared at the AGM of 11 August 2025 (per Britannia’s board-meeting outcome of 8 May 2025) — gives a payout of 82.9% on the same EPS. Matching the dividend to the year it was declared for is the tidier method; the two land close here.

Britannia pays out about four-fifths of what it earns. That pattern is common in mature companies, where the business often throws off more cash than it can reinvest at a similar return. Its sustainable growth rate is about 9.8% — a consequence of returning most of the profit rather than retaining it. A company with a 52.5% ROE that retained everything could in theory grow equity at 52.5% a year. Why a particular board picks a particular payout isn’t something these numbers can tell you.

This is also the arithmetic behind a point the PEG post stumbled on: Britannia’s FY25 profit growth was 1.8%. With an 81% payout, retained profit alone funds growth of roughly 9.8% a year — so modest growth is what the arithmetic points to, even if 1.8% sits well below that. The rest of that year’s gap was the cost squeeze covered in the operating leverage post, not the payout.

🧒 Explain it like I'm 10 (optional — skip if this is already clear)

You and your parents own your lemonade stand half each. It earns ₹100. You pay out ₹80 — ₹40 to your parents, who own half the stand, and ₹40 to you — and keep ₹20 in the stand to buy more lemons. The stand’s payout is 80%.

Next summer, the extra lemons you bought with ₹20 earn you a bit more. If you had kept all ₹100, you’d have five times as many extra lemons — and grow a lot faster. Keeping less means paying out more now and growing less later. Neither is wrong; it depends on whether more lemons would actually sell.

Common mistakes

  • Confusing payout ratio with dividend yield. Payout is dividend ÷ profit; yield is dividend ÷ price. Britannia’s payout is 81%; its yield is 1.26%.
  • Reading a high payout as generosity. Often it means the company has run out of high-return places to reinvest. That can be the right call — or a sign growth has stalled.
  • Reading a low payout as stinginess. A company retaining 60% and earning 34% on it is compounding your money for you. Ask what the ROE on retained capital is, not just the payout.
  • Ignoring buybacks. Companies also return cash by buying back shares. A dividend-only payout ratio understates total distribution for companies that buy back regularly.
  • Computing payout on one year’s EPS with an exceptional item in it. A one-off gain shrinks the ratio; a one-off charge inflates it. Use a normal year, or several.

Takeaway: payout ratio is the share of profit paid out as dividends; retention is what’s kept, and ROE times retention says how fast a company can grow on its own money. A high or low payout isn’t better or worse — each is an answer to “can we reinvest this well?”
