What it means
The ratio compares cash from operating activities with all cash coming in from every source, including asset disposals in investing activities and new borrowing or share issues in financing activities. Expressed as a percentage, it tells you how much of the year's incoming cash the business generated by simply doing what it does.
It matters because the headline movement in the bank balance is easy to misread. A company that sold its warehouse and drew down a new loan can show a rising cash balance while its actual trading consumed cash, and this ratio separates those two very different stories.
Analysts and lenders use it as a sustainability test. Operating cash flow can be repeated year after year, whereas asset sales are finite and new borrowings must eventually be repaid, so a business relying on the latter two is running on sources that will run out.
Reading the trend matters more than any single year. A ratio that falls steadily over three or four years is a signal that trading is covering less and less of the company's needs, even if profits still look acceptable.
The nuance is that a low ratio is not automatically bad. A young business raising equity to build a product, or an established one borrowing to acquire a competitor, will show a low ratio for entirely deliberate reasons, so the number should be read against what management said it planned to do.
In practice
Real-world examples.
Example
A hotel group shows a rising cash balance that a credit analyst traces to two property sales and a refinancing. Its cash generating power ratio of 28% prompts a request for a covenant tied to operating cash flow rather than to total liquidity. The group accepts, because refusing would have signalled that trading could not support the test.
Example
A mature engineering firm reports a ratio above 90% for five consecutive years. Its lender offers finer pricing on renewal because almost all of the incoming cash is repeatable trading cash, which makes the forecast far easier to rely on. The saving on interest amounts to a meaningful share of the firm's annual training budget.
Example
A retailer's ratio drops from 80% to 45% in a single year after a large store refurbishment funded by borrowing. Management explains the dip as planned investment, and the ratio recovers to 78% the following year as promised. Because the fall had been forecast in advance, the board treated it as a milestone rather than a warning.
Think of it
“Cash generating power shows how much cash your sales engine produces-cash efficiency of your business.
Formula
Calculation
Cash generating power ratio = Cash flow from operating activities / (Cash flow from operating activities + Investing cash inflows + Financing cash inflows)
A logistics company reports operating cash flow of $4,000,000 for the year. It also received $1,000,000 from selling surplus depot land and $3,000,000 from a new term loan, so total cash inflows are $4,000,000 + $1,000,000 + $3,000,000 = $8,000,000.
The ratio is $4,000,000 / $8,000,000 = 50%, meaning only half the cash that came in was generated by trading. The following year operating cash flow rises to $6,000,000, asset sales fall to $500,000 and new financing falls to $1,500,000, giving total inflows of $6,000,000 + $500,000 + $1,500,000 = $8,000,000 again, but a ratio of $6,000,000 / $8,000,000 = 75%. The bank balance behaved similarly in both years, yet the second year was far healthier.Case study
Seen in the real world.
The following is an illustrative and fictional example. Voss Haulage Group, an invented freight operator, told its shareholders that cash had improved for three years running, pointing to a bank balance that had grown from $2,000,000 to $6,000,000.
A non executive director calculated the cash generating power ratio for each year and found it had fallen from 74% to 61% and then to 39%. The growth in cash had come from selling two depots and refinancing the fleet, while operating cash flow had actually declined as maintenance costs on ageing trucks climbed.
In this fictional scenario the board commissioned a review of fleet replacement and route profitability rather than celebrating the cash balance. The point of the ratio is precisely this: it asks where the cash came from, not simply how much of it is sitting in the account.
Watch out
Common mistakes.
- Judging cash health from the movement in the bank balance, which mixes earned cash with borrowed and sold cash in a single figure.
- Netting investing and financing flows before calculating, so that a large disposal offset by a large purchase disappears from the denominator entirely.
- Reading one year in isolation, when a single deliberate investment year can produce a low ratio in an otherwise strong business.
Questions
People also ask.
What is a good cash generating power ratio?
Above about 80% is generally considered strong for a mature business, while sustained readings below 50% deserve an explanation.
Does the ratio work for startups?
It is less meaningful, because early stage companies are funded by design and will show very low ratios until trading matures.
Where do the inputs come from?
All three figures come straight from the cash flow statement, using the operating, investing and financing sections respectively.
