What it means
Every year a company splits its profit two ways: some goes out as dividends and the rest is retained in the business. Shareholders are effectively lending that retained portion back to management to invest on their behalf.
The ratio grades that decision by comparing the growth in earnings with the amount held back. The idea matters most for investors choosing between a company that pays generous dividends and one that keeps its cash.
If the retaining company earns a poor return on what it keeps, shareholders would have been better off taking the money and investing it themselves. The usual calculation works per share and over a multi-year window, typically five or ten years.
You take the increase in earnings per share across the period and divide it by cumulative earnings per share less cumulative dividends per share. A single year is far too short, because investments rarely pay back inside twelve months.
A simpler variant that appears in management accounts divides current net income by the closing retained earnings balance on the balance sheet. It is quicker to produce but much cruder, since the retained earnings balance includes profits kept decades ago and takes no account of what has already been spent.
The ratio has real limits worth stating plainly. Earnings growth can come from acquisitions, cost cutting or a favourable market rather than from reinvested profit, so a high figure is suggestive rather than conclusive.
It also breaks down entirely for companies with negative retained earnings or an erratic dividend record.
In practice
Real-world examples.
Example
A consumer goods company retains 60% of its profit for a decade and its earnings per share doubles. An investor calculating the return on retained earnings finds it comfortably above the return available elsewhere and concludes the low dividend is justified.
Example
A supermarket chain retains $400,000,000 over five years to open new stores, but earnings per share rises by only $0.05 on a share count of 200,000,000, so the retained money added roughly $10,000,000 of annual earnings. The board faces awkward questions about whether a special dividend would have served shareholders better.
Example
A private engineering firm uses the simpler balance sheet version each year as a rough check on capital discipline. When the figure slides from 18% to 9% over three years, the directors trace it to a warehouse extension that never reached the volumes used to justify it.
Think of it
“Return on retained earnings shows what return your reinvested profits are generating.
Formula
Calculation
Return on retained earnings = (Latest earnings per share - Earliest earnings per share) / (Cumulative earnings per share - Cumulative dividends per share)
A listed engineering group earned $2.00 per share five years ago and $3.20 per share in the most recent year, an increase of $1.20 per share.
Across those five years it reported cumulative earnings of $13.00 per share and paid cumulative dividends of $7.00 per share.
Retained per share = $13.00 - $7.00 = $6.00.
Return on retained earnings = $1.20 / $6.00 = 0.20, or 20%. Every dollar the company held back from shareholders now produces an extra 20 cents of annual earnings.
The cruder balance sheet version would set current net income of $4,000,000 against a retained earnings balance of $25,000,000, giving $4,000,000 / $25,000,000 = 0.16, or 16%.Case study
Seen in the real world.
Bramble and Vance Tools is an invented company used here as an illustrative example. It had a proud record of retaining most of its profit, describing the policy in every annual report as a commitment to long-term growth.
A shareholder ran the numbers over the previous decade. Earnings per share had crept from $1.40 to $1.70, an increase of $0.30, while cumulative earnings of $16.00 per share against cumulative dividends of $4.00 per share meant $12.00 per share had been retained. The return on retained earnings was $0.30 / $12.00 = 2.5%, well below what a simple bond portfolio would have paid.
In this fictional case the board responded by raising the dividend payout ratio from 25% to 55% and cancelling two speculative product programmes. Earnings per share barely moved, but shareholders received the cash and the discussion at the annual meeting shifted from ambition to evidence.
Watch out
Common mistakes.
- Measuring the ratio over a single year, which is far too short for reinvestment to show up in earnings.
- Assuming any earnings growth in the period was caused by retained profit, when acquisitions or a rising market may explain most of it.
- Using the retained earnings balance as though it were a pot of cash, when it is an accounting record of past profits already spent on assets.
Questions
People also ask.
What counts as a good return on retained earnings?
A reasonable test is whether it beats the return shareholders could get on their own, so a figure comfortably above the company's cost of equity is the benchmark.
Can the ratio be negative?
Yes, if earnings per share has fallen over the period, which suggests retained profit has been invested in something that destroyed value.
Does a company with no dividend automatically score badly?
Not at all; if it is retaining everything and earnings per share is growing quickly, the ratio can be very high, which is the usual defence of a zero dividend policy.
