Use Cases

Assess business cash generation

Use this calculator to evaluate how much cash your core business operations generate after accounting for non-cash expenses and working capital changes. This helps in budgeting and financial planning.

Example: A company with net income of $100,000, depreciation of $20,000, and a $5,000 increase in working capital has an OCF of $115,000.

Compare with net income

Compare operating cash flow to net income to see the quality of earnings. Consistently higher OCF than net income may indicate strong cash generation, while lower OCF could signal cash flow issues.

Example: If net income is $50,000 but OCF is only $30,000, it may indicate heavy investment in working capital.

Frequently Asked Questions

What is operating cash flow?
Operating cash flow (OCF) is the cash generated from a company's normal business operations. It indicates whether a company can generate sufficient positive cash flow to maintain and grow its operations, or if it may need external financing.
How is operating cash flow calculated?
Operating cash flow is calculated by taking net income, adding back non-cash expenses like depreciation and amortization, and then adjusting for changes in net working capital. The formula is: OCF = Net Income + Depreciation & Amortization - Increase in Net Working Capital.
Why is the change in net working capital subtracted?
An increase in net working capital means more cash is tied up in current assets (like inventory or accounts receivable) or used to pay current liabilities. This reduces the cash available from operations, so it is subtracted from net income to reflect the actual cash generated.

Tips & Common Mistakes

Tips

  • Ensure you use the correct sign for the change in net working capital. An increase is subtracted, while a decrease would be added (though this calculator only asks for increase).
  • Depreciation and amortization are non-cash expenses, so they are added back to net income to reflect actual cash flow.
  • Use consistent accounting periods (e.g., annual or quarterly) for all inputs to get an accurate OCF figure.
  • Regularly calculate OCF to monitor trends in your business's cash generation over time.

Common Mistakes to Avoid

  • Forgetting to add back depreciation and amortization, which understates operating cash flow.
  • Subtracting the increase in net working capital when it should be added (if working capital decreases, but this calculator only handles increases).
  • Using net income that includes non-operating items like interest or taxes, which can distort the OCF calculation.
