Key cash flow ratios

Cash flow ratios help business owners assess the financial health, efficiency, and liquidity of their business by analyzing how cash is generated and used. Unlike ratios based on accounting profits, cash flow ratios focus on actual cash movements, making them more reliable for evaluating a business’s ability to meet short-term obligations and sustain operations.

Here are the key cash flow ratios and their implications:

1. Operating Cash Flow Ratio (Liquidity)

Formula:

Operating Cash Flow Ratio = Operating Cash Flow/Current Liabilities

Purpose:
Measures a business’s ability to cover its short-term liabilities with cash generated from operations.

Implications:

• > 1: Strong liquidity position.
• < 1: Potential liquidity issues; may struggle to meet short-term obligations.

2. Free Cash Flow (FCF)

Formula:

Free Cash Flow = Operating Cash Flow−Capital Expenditures

Purpose:
Indicates the cash available after maintaining or expanding asset base (e.g., equipment, property).

Implications:

• Positive FCF: Business can reinvest, repay debt, or pay dividends.
• Negative FCF: May indicate high investment in growth or cash flow problems.

3. Cash Flow to Debt Ratio (Solvency)

Formula:

Cash Flow to Debt Ratio = Operating Cash Flow/Total Debt

Purpose:
Assesses a business’s ability to repay total debt using operational cash.

Implications:

• Higher ratio: Business is more capable of managing debt.
• Lower ratio: May struggle with debt obligations.

4. Cash Flow Margin

Formula:

Cash Flow Margin = (Operating Cash Flow/Net Sales) x 100

Purpose:
Shows how efficiently a company converts sales into actual cash.

Implications:

• Higher %: More cash is generated from sales.
• Low or negative %: Poor collection of receivables or high operating costs.

5. Capital Expenditure (CapEx) Ratio

Formula:

CapEx Ratio = Operating Cash Flow/Capital Expenditures

Purpose:
Indicates whether the business is generating enough cash to fund capital investments.

Implications:

• > 1: Business is funding capital spending from operations.
• < 1: May need external financing for asset purchases.

6. Cash Return on Assets

Formula:

Cash Return on Assets = (Operating Cash Flow/Average Total Assets) x 100

Purpose:
Measures how effectively a company uses its assets to generate cash.

Implications:

• Higher %: Better asset utilization.
• Lower %: Inefficient use of assets or cash flow issues.
