Every year a profitable business makes a choice. It can pay its profits out to its owners, use them to buy back shares, or keep them and put them back to work. The profits it keeps accumulate on the balance sheet as retained earnings.
It is an unglamorous line, tucked into the equity section near the bottom of the balance sheet. Warren Buffett and the Interpretation of Financial Statements nonetheless describes it as one of the most important numbers a reader can find. This article explains what retained earnings are, why their growth reveals so much, how compounding turns retained profits into wealth (or fails to), and what the idea means for anyone running a business that must decide every year what to do with its profits.
What retained earnings actually are
Retained earnings are the running total of all profits a company has kept since it began, after dividends and share buybacks. A profitable year adds to the total; a loss subtracts from it. If losses exceed everything accumulated before, the figure turns negative and is usually shown as accumulated losses.
A simple reconciliation shows how the figure moves each year:
| Amount | |
|---|---|
| Retained earnings at start of year | $40.0m |
| plus net profit for the year | $8.0m |
| less dividends paid | $3.0m |
| Retained earnings at end of year | $45.0m |
Retained earnings are not a pile of cash. This is the most common misunderstanding. The money has usually been spent on equipment, inventory, acquisitions, research or other investments. The figure records how much of the owners’ profit has been reinvested in the business over its life, not where that money is now. To find the cash, look at the asset side of the balance sheet.
Why the growth rate matters
The book’s argument is simple. If a company is not adding to its retained earnings, it is not growing its net worth. If it is not growing its net worth, it is unlikely to create much wealth for its owners over the long run.
So the authors suggest watching the rate at which retained earnings grow. A business with a durable advantage tends to add to them steadily, year after year, because it earns consistently and needs relatively little of that profit to stand still. A struggling business shows retained earnings that stall, shrink or swing with its losses.
This connects to several other signals discussed in this series. A business that needs heavy capital spending, high research budgets or constant marketing just to hold its position has less profit left to retain. A business with low debt does not need to direct its profits to lenders. Retained earnings, in a sense, are where all the other signals add up.
Growth relative to profits
It is also worth checking that the growth in retained earnings matches reported profits less distributions. If a company reports strong profits but its retained earnings barely move, something else is going on: large dividends, buybacks, or losses recognised in ways that bypass the headline profit. The reconciliation in the notes, usually called the statement of changes in equity, explains the difference.
Compounding needs a good place to reinvest
Retaining profits is only valuable if they are put to good use. A dollar retained should eventually be worth more than a dollar to the owner. Otherwise they would have been better off receiving it.
Buffett has long described a simple test in his letters to shareholders: over time, each dollar a company retains should create at least a dollar of value for its owners. If it does not, the profits would have been better distributed.
This is where compounding comes in. A business that can reinvest its profits at a high rate of return, year after year, grows its earning power on top of its earning power. Over decades the effect is enormous. Buffett’s own company, Berkshire Hathaway, is the best-known example: for most of its history it paid no dividend and retained its earnings, and the book credits that policy with much of the growth in its value.
The arithmetic of compounding
Consider two illustrative businesses that each start with $10 million of equity, keep all their profits and reinvest them at the same rate they currently earn.
| Reinvesting at 20% | Reinvesting at 8% | |
|---|---|---|
| Equity at start | $10.0m | $10.0m |
| Equity after 10 years | about $62m | about $22m |
| Equity after 20 years | about $383m | about $47m |
Over ten years, the 20% business grows to nearly three times the size of the 8% business. Over twenty years, more than eight times. The difference comes entirely from the rate at which retained profits are reinvested. Time magnifies small differences in return into very large differences in outcome.
These are illustrations, and no real business reinvests everything at a constant rate for twenty years. But the shape is real, and it explains why the book cares so much about businesses that can retain profits and reinvest them well.
The reverse is also true
A business that retains profits and invests them poorly (in low-return projects, overpriced acquisitions or efforts to defend a weakening position) destroys value even while its retained earnings rise. On paper, the figure grows. In reality, owners would have been better off with the cash.
That is why retained earnings should be read alongside return on equity, the subject of another article in this series. Rising retained earnings with steady or rising returns suggest a productive engine. Rising retained earnings with falling returns suggest a business accumulating capital it cannot use well.
Why some excellent businesses retain little
A business that pays out most of its profits is not necessarily weak. There are two very different reasons a company might distribute rather than retain:
- It has nowhere good to reinvest. The business may be mature, with limited growth opportunities. Distributing profits is then the honest choice.
- It is so profitable it does not need the money. Some businesses with exceptional advantages generate far more cash than they can use and return the surplus through dividends or buybacks.
The book notes that some highly profitable companies have paid out so much that their retained earnings and even their total equity have fallen. The earnings history distinguishes these from businesses that have simply lost money.
The Australian context
In Australia, the dividend imputation system means that dividends paid from profits on which company tax has been paid can carry franking credits to shareholders. This is often cited as one reason many Australian listed companies pay out a larger share of their profits than companies in some other countries. When comparing retention rates internationally, it is worth keeping that difference in mind. Tax treatment depends on individual circumstances; check with an adviser.
Where retained profit goes
Because retained earnings are not cash, it is worth following the money. Comparing two balance sheets a year apart shows where retained profit was deployed. Common destinations include:
- new equipment, property or systems, visible as growth in non-current assets
- inventory and receivables, as a growing business carries more stock and extends more credit
- acquisitions, often shown partly as goodwill and other intangible assets
- debt repayment, visible as falling borrowings
- cash reserves, visible as a growing cash balance
Each destination carries a different expected return. Debt repayment earns the interest rate saved. Equipment earns whatever extra profit it produces. Acquisitions earn whatever the acquired business contributes, less what was paid for it. Tracing where retained profit went, and what it earned there, is the most direct way to judge whether retention is creating value.
Signs worth noticing
When reading a balance sheet over several years, ask:
- Are retained earnings growing steadily, or erratically?
- Does the growth match the company’s reported profits less dividends and buybacks?
- Are large losses periodically wiping out progress?
- Is the company generating good returns on the capital it keeps?
- If it pays out most of its profits instead, is that because it lacks good opportunities, or because it is so profitable it simply does not need the money?
- When it retains profits, what does management say it will do with them, and did it do that in previous years?
The last question is often the most revealing. Management’s track record of reinvesting retained profits, visible in past annual reports, says a great deal about how well future retained profits will be used.
What this means for building a business
For a young business, retained earnings are often the cheapest and safest source of growth capital available. Profits reinvested do not dilute ownership and do not need to be repaid. A business that can fund its own growth keeps its independence.
That suggests a few habits.
Design for profits that can fund growth. A business that must raise money every time it wants to expand is permanently dependent on others. Healthy margins and modest capital needs make self-funding possible.
Decide deliberately how much to retain. Owners of small companies often take most profits out as drawings or dividends by default. A deliberate decision, made each year, about how much the business genuinely needs keeps both the business and the owners’ finances healthy.
Reinvest where returns are highest. Before adding capacity, products or people, ask what return the money is likely to earn, and compare it with the simplest alternative, such as paying down debt or holding cash for resilience.
Track what retained money achieves. When profits are reinvested in a new machine, product or hire, check a year later whether the expected return materialised. This builds judgement for the next decision.
Be honest when there is nowhere good to reinvest. Keeping profits in a business that cannot use them well helps no one. Paying them out, or holding them as a reserve, may be the better choice.
Keep a reserve. Some retained profit held as cash gives resilience against downturns and the ability to act on opportunities without borrowing.
The tax treatment of retained and distributed profits varies by business structure, so owners should take advice from an accountant when deciding how to handle them.
A worked example
A small specialty bakery earns $120,000 a year in profit after paying its owner a fair salary. This is an illustration.
For the first two years, the owner takes most of the profit out. The bakery runs at capacity, turning away wholesale orders because the oven cannot produce more.
In the third year, the owner decides to retain $80,000 of profit and invest it in a second oven and a part-time baker. Wholesale orders, previously turned away, now add $90,000 of revenue at a healthy margin, lifting annual profit by around $35,000. The retained $80,000 is earning a return of more than 40% a year.
The following year, the owner considers retaining profits again, this time to open a second shop. The analysis is less favourable: rent is high, the location unproven and the likely return modest. The owner decides instead to retain a smaller amount as a reserve and distribute the rest, revisiting the expansion when a better site appears.
Both decisions used the same principle. Retain profits when they can earn a strong return; distribute them when they cannot.
Common mistakes
Treating retained earnings as cash. The money has usually been spent.
Retaining by default. Keeping profits without a productive use for them wastes the owners’ money.
Distributing by default. Taking everything out starves a business that has good opportunities.
Ignoring the return on retained profits. Rising retained earnings mean little if returns are falling.
Overlooking the statement of changes in equity. It explains why retained earnings moved as they did.
Questions to ask
- How fast have retained earnings grown over the last ten years?
- What return has the business earned on the profits it kept?
- What has management done with retained profits in the past, and did it work?
- Would owners have been better off receiving the cash?
- For your own business: what would the next $50,000 of retained profit earn, and how sure are you?
Bringing it together
Retained earnings record the profits a business has kept and reinvested over its life. Their steady growth is one of the clearest signs of a business with a durable advantage, because it shows consistent profits that are not consumed just to stand still.
But retention is only valuable when the money is reinvested well. Compounding rewards patience, and it rewards it handsomely, but only when the engine underneath is genuinely productive. For owners and founders alike, the discipline is the same: keep profits when they can earn more inside the business than outside it, and be honest when they cannot.
