Cash Flow Ratios and Analysis
Cash flow ratios let you move beyond the raw numbers on the Statement of Cash Flows and start asking sharper questions: Can this company cover its obligations? Is it actually turning sales into cash? These ratios are how investors and creditors assess a company's liquidity (ability to meet short-term obligations) and solvency (ability to meet long-term obligations).
Three ratios show up most often in this analysis: free cash flow, cash flows to sales, and cash flows to assets.
Free Cash Flow: Calculation and Interpretation
Free cash flow (FCF) is the cash left over after a company pays for its operations and maintains its capital assets. It answers a simple question: How much cash is truly available for discretionary use?
- Positive FCF means the company has surplus cash after covering operating costs and capital spending. That surplus can go toward expansion (opening new locations), paying down debt, increasing dividends, or repurchasing shares.
- Negative FCF means the company spent more than it generated from operations. It will need to raise additional capital, either by borrowing (issuing bonds or taking loans) or by issuing new equity (selling additional shares).
Negative FCF isn't automatically bad. A young, fast-growing company might have negative FCF because it's investing heavily in new equipment or facilities. But if a mature company consistently shows negative FCF, that's a red flag for creditors and investors.
Cash Flows to Sales Ratio
This ratio measures how well a company converts its revenue into actual operating cash.
A higher ratio means the company is efficiently turning sales dollars into cash. For example, a ratio of 0.20 means the company generates $0.20 in operating cash flow for every $1.00 of net sales.
A lower ratio suggests the company is struggling to collect cash from its sales. Common causes include:
- Lenient credit policies that let customers delay payment
- Difficulty collecting receivables (outstanding customer invoices piling up)
- High operating expenses eating into cash generated from revenue
This ratio is especially useful for comparing companies within the same industry, since different industries have very different norms for how quickly sales convert to cash.
Cash Flows to Assets Ratio
This ratio evaluates how effectively a company uses its total asset base to generate cash.
Note that the denominator uses average total assets (beginning balance + ending balance, divided by 2), which smooths out fluctuations during the period.
- A higher ratio indicates the company is putting its assets to productive use, generating strong cash flow relative to its investment in equipment, property, inventory, and other assets.
- A lower ratio may point to underperforming investments, obsolete assets (outdated machinery sitting idle), or poor asset management.
Comparing this ratio against industry benchmarks is important. A capital-intensive manufacturer will naturally have a lower ratio than a software company, so you need to compare against similar businesses to draw meaningful conclusions.
Additional Cash Flow Ratios
Two other ratios round out the liquidity and solvency picture:
- Cash flow coverage ratio measures whether operating cash flow is sufficient to cover a company's debt obligations (typically interest and principal payments). A ratio below 1.0 means the company can't cover its debt payments from operations alone.
- Cash flow adequacy ratio takes a broader view, assessing whether operating cash flow covers capital expenditures, debt repayments, and dividends all together. This tells you if the company is self-sustaining or if it needs outside financing to keep up with its commitments.
Both ratios complement FCF and the other metrics above. Together, they give you a well-rounded view of whether a company can meet its short-term needs (liquidity) and sustain itself over the long run (solvency).
