When a corporation generates net profit, management faces a fundamental capital allocation decision: distribute cash to shareholders as dividends or retain the cash within the company to fund research, capital expenditures, or debt reduction. The percentage of net income retained to fund future business expansion is the Retention Ratio (also called the Plowback Ratio).

Our free Retention Ratio Calculator computes the exact earnings retention percentage, plowback rate, and resulting Sustainable Growth Rate (SGR) for corporate equity.


How to Calculate the Retention Ratio & Sustainable Growth Rate

The Retention Ratio is the mathematical inverse of the Dividend Payout Ratio.

Retention Ratio Formula (Inverse Payout):

Retention Ratio (%) = 100% - Dividend Payout Ratio (%)

Retention Ratio Formula (Direct Net Income):

Retention Ratio = ( Net Income - Total Dividends Paid ) / Net Income

Sustainable Growth Rate (SGR) Formula:

Sustainable Growth Rate (SGR) = Retention Ratio × Return on Equity (ROE)


Step-by-Step Corporate Growth Example

Suppose a firm reports Earnings Per Share (EPS) of $5.00 and pays an annual Dividend Per Share (DPS) of $1.50. The company maintains a Return on Equity (ROE) of 15.0%.

Let’s calculate the Dividend Payout Ratio, Retention Ratio, and Sustainable Growth Rate:

Dividend Payout Ratio = ($1.50 / $5.00) × 100 = 30.0%

Retention Ratio (b) = 100.0% - 30.0% = 70.0% (0.70)

Retained Capital Per Share = $5.00 - $1.50 = $3.50 per share

Sustainable Growth Rate (SGR) = 0.70 × 15.0% = 10.50% per year

Earnings Allocation Metric Per-Share Dollar Amount Percentage Share Strategic Business Function
Total Net Earnings (EPS) $5.00 / share 100.0% Total annual net income pool
Distributed Dividends (DPS) $1.50 / share 30.0% Cash return to shareholders
Retained Earnings (Plowback) $3.50 / share 70.0% Retention Reinvested into corporate growth
Sustainable Growth Rate (SGR) 70% Retained × 15% ROE — 10.50% Annual Expansion Cap

Frequently Asked Questions (FAQ)

What is the Retention Ratio (Plowback Ratio)?

The Retention Ratio (or Plowback Ratio) is the proportion of net earnings retained within a business rather than paid out as cash dividends to stockholders.

Why do fast-growing tech companies have a 100% Retention Ratio?

High-growth technology companies typically have a 100% Retention Ratio (0% Payout Ratio) because they have high-return investment opportunities. Reinvesting 100% of profits back into R&D and market expansion creates far greater long-term value for shareholders than paying out cash dividends.

How does the Retention Ratio influence the Sustainable Growth Rate?

The Sustainable Growth Rate (SGR) defines the maximum annual sales growth a firm can achieve without taking on additional financial leverage or issuing new equity. Multiplying the Retention Ratio by Return on Equity (ROE) determines this maximum internal growth ceiling.
