What it means
Profit and cash are not the same thing, and the gap between them is where a lot of businesses get into trouble. Cash conversion efficiency puts a single number on that gap so it can be tracked over time rather than discovered during a crisis.
The most common version divides operating cash flow by revenue, giving the number of cents of cash generated per dollar of sales. An alternative divides operating cash flow by earnings before interest, tax, depreciation and amortisation, which shows what share of underlying trading profit survives the journey into the bank.
A falling ratio while revenue grows is one of the classic early warning signs in financial analysis. It usually means the business is funding its own growth through working capital, building stock and extending credit faster than customers are paying.
Different business models sit naturally at different levels, so context is everything. Subscription software firms that bill annually in advance often convert well above 100% of profit into cash, while heavy equipment manufacturers with long build cycles routinely convert far less.
The main lever on the ratio is working capital rather than pricing. Tightening collections, shortening stock holding and negotiating supplier terms all move cash conversion without changing a single line on the profit statement.
In practice
Real-world examples.
Example
A private equity investor screening acquisition targets rejects a distributor whose revenue grew 30% while cash conversion fell from 85% to 41%. The growth was real, but it was being funded almost entirely by stock the business could not sell fast enough.
Example
A subscription analytics company reports cash conversion of 118% against EBITDA because customers pay for a full year up front. Its board watches the figure closely, knowing it would fall sharply if the firm ever moved to monthly billing.
Example
A shipbuilder measures cash conversion over a rolling three year window rather than annually. Any single year is distorted by milestone payments on long contracts, and the longer window is the only way to see the real trend.
Think of it
“Cash conversion efficiency shows how well you turn profits into actual cash-the conversion rate.
Formula
Calculation
Cash conversion efficiency = operating cash flow / revenue x 100, or operating cash flow / EBITDA x 100
A packaging manufacturer reports revenue of $12,000,000 for the year and net cash generated from operating activities of $2,400,000. Cash conversion efficiency against revenue = $2,400,000 / $12,000,000 x 100 = 20%, so every dollar of sales produced 20 cents of operating cash.
The same company reports EBITDA of $3,000,000. On the profit based measure, cash conversion = $2,400,000 / $3,000,000 x 100 = 80%, meaning a fifth of its trading profit stayed locked up in working capital over the year.
If the business cut its receivables by $300,000 through better collections, operating cash flow would rise to $2,700,000 and the profit based conversion would improve to $2,700,000 / $3,000,000 x 100 = 90%.Case study
Seen in the real world.
This is an illustrative scenario with an invented company. Copperfield Tools, a fictional supplier of hand tools to trade merchants, celebrated four consecutive years of double digit revenue growth and rising reported profit. Its overdraft, however, crept up every single year.
The finance director calculated cash conversion against EBITDA and found it had fallen from 92% to 48% across the four years. Stock had risen from eleven weeks of cover to nineteen as the range expanded, and average customer payment had drifted from 42 days to 58 while nobody was watching either number.
The fictional business cut roughly 400 slow moving product lines, moved its three largest customers to shorter terms in exchange for a small volume rebate, and made cash conversion a standing board metric. Two years later revenue was broadly flat but conversion was back above 85%, and the overdraft was cleared.
Watch out
Common mistakes.
- Using net profit instead of operating cash flow in the numerator, which measures nothing at all since both sides then come from the same accrual figures.
- Comparing the ratio across industries with very different working capital patterns and concluding one management team is better than another.
- Reading a single strong year as a trend when it may simply reflect a large customer prepayment or a deferred supplier payment run.
Questions
People also ask.
What is a good cash conversion efficiency?
Against EBITDA, many analysts look for 80% or better as a sign of healthy working capital management, but the right benchmark is the company's own history.
Can the ratio exceed 100%?
Yes, and it commonly does where customers pay in advance or where large non cash charges sit inside the profit figure.
Is it the same as the cash conversion cycle?
No, the cycle measures the number of days cash is tied up in working capital, while this ratio measures the share of sales or profit that reaches the bank.
