Retention Ratio
60.0%
Reinvestment Analysis
With a retention ratio of 60%, the company keeps $6,000,000 of its $10,000,000 earnings to fund growth and returns $4,000,000 to shareholders. This balanced approach signals a maturing firm that still reinvests meaningfully. The key question is whether the retained portion earns more than shareholders could earn elsewhere at similar risk.
*The retention ratio is derived from reported net profit (NPAT) and dividends paid. It ignores buybacks, debt repayment and acquisition spending as alternative uses of earnings. Combine with ROE and payout-ratio analysis before drawing conclusions. Educational only, not investment advice.
What a Company Does With Your Share of the Profit
Every dollar an ASX company earns belongs, ultimately, to its shareholders — and management returns it in exactly one of two ways: paid out as dividends or retained inside the business to fund growth, repay debt or build capability. The retention ratio measures that split. A company retaining eighty percent of its profit is telling you it sees productive uses for capital — new stores, technology, acquisitions, debt reduction. A company paying out ninety percent is telling you something too: either the business is a genuine cash cow with few good reinvestment options, or growth has stalled and the dividend is doing the heavy lifting for the share price. The ratio matters more in Australia than almost anywhere else because of franking credits. Our market is structurally tilted toward high-payout companies — the big four banks, Telstra, the supermarkets — because fully franked dividends carry tax credits that super funds and low-rate taxpayers value enormously. Meanwhile the market's compounders, from healthcare to technology names, retain most earnings and rarely pay much at all. Neither strategy is inherently superior; what matters is whether retained earnings actually compound into higher future profits. This calculator computes the retention ratio instantly from net profit after tax and dividends paid, then shows what the split implies for payout coverage, implied dividend yield and whether the retained slice is being rewarded with growth.
One Subtraction, One Division, Several Verdicts
The core arithmetic takes one line: retention ratio equals net profit minus dividends paid, divided by net profit after tax (NPAT). Its mirror image, the payout ratio, is simply dividends divided by NPAT — together they always sum to one hundred percent, so knowing one gives you the other. The inputs come straight from the income statement: statutory NPAT from continuing operations and total dividends declared against that year's earnings, including any interim amounts. Two companion figures give the ratio investment meaning. Dividend yield divides total dividends by the current share price, showing the income stream a buyer locks in today; dividing dividends by shares outstanding first converts the pool into a per-share figure comparable across companies. Earnings per share (NPAT over shares outstanding) completes the picture: when retained earnings are working, EPS should grow roughly in proportion to how much is retained — the intuition behind the sustainable growth rate, where expected growth approximates ROE multiplied by the retention ratio. An eighty percent retainer earning fifteen percent on equity should compound book value around twelve percent annually; if reported EPS instead stagnates, management is either destroying the retained capital or parking it unproductively, and the ratio becomes evidence rather than promise.
Expert Insights
Franking Makes Australia's Payout Culture Rational — Up to a Point
Since imputation credits travel with dividends, a fully franked payout from a bank effectively delivers pre-tax earnings to a zero-rate super pension account with the credit refunded. That is why ASX incumbents sustain payout ratios of seventy to ninety percent that would look reckless in the US: shareholders genuinely receive most of the profit. The trap is reading a high payout as safety. Banks cut dividends in 2020 under APRA's direction within weeks — payout ratios describe policy, not protection, and policy changes fast when the regulator or the cycle demands it.
Retained Earnings Are a Loan You Extend to Management
Every dollar not paid out is your money left on deposit with the board, and the interest it earns should show up as compounding earnings per share. The discipline test is simple: compare five-year EPS growth to what retention times ROE promised. Companies like the market's long-run industrial compounders passed this test for decades; others retain everything and deliver nothing, diluting holders through serial capital raises while never cutting the rhetoric about growth. If retention keeps rising while returns on that retention keep falling, the honest interpretation is empire-building — and your share of profit is funding it.
Watch Retention Through the Commodity Cycle
Resource companies invert their ratios violently across the cycle: near-zero payouts and full retention through downturns, then enormous special dividends and buybacks at peaks. Reading a miner's point-in-time retention ratio tells you where you are in the cycle, not what the business is. For cyclicals, average the ratio across the full cycle before drawing conclusions about capital discipline — and prefer management teams whose peak-year distributions prove they do not confuse a commodity price with a business model.
Actionable Tips
- 1
Pull NPAT and Dividends From the Same Reporting Year
Use the annual report's statutory NPAT for continuing operations and the total dividends declared against that year, including interims. Mixing a half-year dividend pool with a full-year profit — or comparing across mismatched financial years — distorts the ratio badly. For half-yearly reporters, double-check whether the 'interim' dividend was already declared against the period you are analysing before concluding the payout jumped.

Read the Ratio Beside ROE, Never Alone
A seventy percent retention means little until you ask what return the retained capital earns. Multiply retention by ROE for the implied sustainable growth rate, then check it against actual five-year EPS growth. Close match: disciplined compounder. Big shortfall: capital is leaking into low-return projects or acquisitions. This two-number check takes minutes per company and screens out far more duds than any single metric.

Match the Ratio to Your Own Tax Position
Your ideal payout differs from the market's. Accumulation-phase super pays fifteen percent and values franking but doesn't need income; a retiree in pension phase wants maximum fully-franked cash flow; a top-bracket earner outside super may actually prefer lower-yield growth because excess franking credits go unrewarded above the top rate. Filter candidates by whether their retention policy fits your stage — the same company can be wrong for one investor and right for another.
Real-World Examples
Marcus Backed the Compounder and Got Paid Differently
Marcus bought an ASX healthcare compounder that paid out barely ten percent of earnings, retaining the rest for expansion and licensing deals. For three years he earned almost no income and doubted himself. But EPS compounded steadily as retained capital produced returns on equity near twenty percent, and the share price followed the earnings. His total return beat every high-yield stock he had ever owned — proof that retention is only bad when management wastes it.
Elena Learnt What a Ninety Percent Payout Really Promises
Drawn to a high-yield energy utility distributing almost everything it earned, Elena assumed the payout was safe because it had run for years. When wholesale costs spiked, the board rebased the dividend by forty percent in a single update — the payout had been consuming nearly all earnings with nothing reserved for the cycle she did not see coming. Her lesson: a payout ratio above eighty-five percent leaves no buffer, whatever the franking attached to it.
The Super Fund Screened With Both Numbers
An SMSF trustee couple built their income sleeve using exactly this discipline: they shortlisted companies with payout ratios between sixty and eighty-five percent, then checked each one's five-year EPS growth against retention times ROE. Two popular high-yielders failed the second test — retained capital vanishing into write-downs — and were excluded despite tempting yields. The final portfolio delivered steady franked income through the following reporting season without a single cut.
Glossary of Terms
- Net Profit After Tax (NPAT)
- The company's statutory bottom-line profit for the period after all expenses, interest and tax — the pool from which dividends are paid or profits retained.
- Payout Ratio
- The percentage of NPAT distributed as dividends — the direct inverse of the retention ratio. Above roughly eighty percent, payouts depend heavily on earnings stability.
- Sustainable Growth Rate
- The estimated pace a company can grow earnings without external funding, approximated by return on equity multiplied by the retention ratio. Comparing it with actual EPS growth tests capital discipline.
