Real cash profit: the test that outsmarts accounting

2026-07-07 · By Lubin Danilo, founder of Lubin Investment

A company's accounting profit can be inflated by depreciation choices or one-off items, without a single extra dollar of real cash entering its coffers. So I systematically check how much of that profit actually turns into available cash: it's one of the ten criteria in my method.

Key takeaways

Accounting profit can be distorted by depreciation rules or one-off items, with no direct link to cash actually generated.
I compute a conversion ratio: free cash flow divided by accounting profit. A ratio near or above 1 signals clean accounting.
Monarch Casino, which I've analyzed on my site, shows a ratio of 1.34: it generates even more cash than its accounting profit suggests.
Fast Retailing (Uniqlo), by contrast, shows a ratio of 0.93: a small portion of its profit doesn't immediately turn into available cash, without that being a red flag on its own.

Why accounting profit is never enough

The net profit a company reports every quarter results from accounting rules that leave real room for interpretation: the pace of asset depreciation, how certain revenue is recognized before it's even collected, or one-off items that artificially inflate a quarter's result. Two companies reporting the same profit can have generated very different amounts of real cash.

That's why I systematically compute a conversion ratio: free cash flow generated, divided by accounting profit. A ratio near or above 1 signals that reported profit truly translates into cash actually sitting in the company's coffers. A ratio well below 1, repeated over several years, should raise a flag: the company might be inflating its reported result without the cash following.

The Monarch Casino case: a ratio above 1

Monarch Casino & Resort, which I've analyzed on my site, shows a conversion ratio of 1.34: it generates even more cash than its accounting profit suggests. That's often a sign of heavy depreciation charges on real estate assets (casinos, hotels) already largely written down on the books, while they keep generating very real cash. That's not abnormal, it's actually a reassuring sign of accounting quality.

The Fast Retailing case: a ratio slightly below 1

Fast Retailing, the parent of Uniqlo which I've also analyzed, shows a ratio of 0.93: a small portion of its accounting profit doesn't immediately turn into available cash. That's not a red flag on its own: in its case, the gap is consistent with the investment needed to open new stores internationally and manage growing inventory, which temporarily ties up cash without erasing accounting profit.

How to read this ratio without getting it wrong

A ratio temporarily below 1 is never automatically a bad sign: a fast-growing company investing in inventory or infrastructure can show a temporarily low ratio without any accounting issue. What should raise a flag is a trend deteriorating over several consecutive years, or an abnormally low ratio with no clear operational justification (inventory growth, physical expansion). A ratio durably above 1, like Monarch Casino's, is generally the most reassuring sign.

What I take away from this

This criterion is one of the ten I apply systematically, precisely because it lets me verify that a reported profit isn't just a cleverly presented accounting figure. Cash, unlike profit, is far harder to manipulate: that's why I trust it more before judging a company's real quality.

FAQ

How do you calculate whether a profit really turns into cash?

I divide the free cash flow generated by accounting profit. A ratio near or above 1 signals clean accounting.

Why does Monarch Casino's ratio exceed 1?

Often because depreciation charges on its real estate assets (casinos, hotels) remain high on the books while those assets keep generating very real cash.

Is Fast Retailing's 0.93 ratio worrying?

Not on its own: it's consistent with the investment needed for international expansion and inventory management, which temporarily ties up cash without erasing accounting profit.

When should a low conversion ratio really raise a flag?

When it deteriorates over several consecutive years with no clear operational justification, rather than a one-off dip tied to an identifiable investment.

Is this criterion part of the Lubin method?

Yes, converting profit into real cash is one of the ten financial criteria I systematically apply to every stock in my screener.

About the author

Written by Lubin Danilo, founder of Lubin Investment. A self-taught individual investor, I find fundamental analysis fascinating, and it has delivered excellent results. For three years now, my performance has beaten the S&P 500. But analyzing every stock took too much time: sites with incomplete data, calculation methods and criteria never aligned with mine. And spotting the best stocks was just as time-consuming, even with my own well-defined checklist. So I put my software development background to work to build this software, base my investment strategy on its results, and share it with people who share the same passion as me. It judges a company's quality and its price separately, using criteria drawn from the financial literature (Warren Buffett, Michael Mauboussin, Aswath Damodaran).
