Calculate operating cash flow using the indirect method. Includes FCF, cash quality ratio, capex coverage, waterfall visualization, and monthly projections.
Operating cash flow (OCF) is the cash generated by a company's core business activities — the lifeblood of any enterprise. Unlike net income, which includes non-cash items like depreciation and accruals, OCF shows the actual cash moving in and out. Profitable companies have gone bankrupt because they couldn't generate enough cash to pay bills, making OCF arguably more important than profit.
This calculator uses the indirect method, starting with net income and adjusting for non-cash charges (depreciation, amortization, stock-based compensation) and changes in working capital (receivables, inventory, payables). The result is how much cash the business actually produced from operations, before investing and financing activities.
Beyond OCF, the calculator computes free cash flow (OCF minus capital expenditures), FCF to equity holders, the cash quality ratio (OCF ÷ Net Income), and capex coverage. The waterfall chart shows exactly how net income transforms into operating and free cash flow, while the projection table models monthly cash generation throughout the year.
"Cash is king" isn't a cliché — it's a survival rule. This calculator shows whether your business actually generates cash, not just paper profits. The waterfall visualization reveals exactly where cash gets created and consumed between the income statement and the bank account. Keep these notes focused on your operational context. Tie the context to the calculator’s intended domain.
Operating Cash Flow (Indirect Method): OCF = Net Income + Non-Cash Charges + Working Capital Changes Non-Cash Charges = Depreciation + Amortization + Stock-Based Comp WC Changes = −ΔReceivables − ΔInventory + ΔPayables + Other Free Cash Flow = OCF − Capital Expenditures FCF to Equity = FCF − Debt Payments Cash Quality Ratio = OCF ÷ Net Income (should be ≥ 1.0)
Result: OCF $171,000 — FCF $121,000 — Quality Ratio 1.14x
Non-cash charges = $25K + $5K = $30K. WC changes = −$10K − $5K + $8K − $2K = −$9K. OCF = $150K + $30K − $9K = $171K. FCF = $171K − $50K = $121K. Quality ratio = $171K ÷ $150K = 1.14x (healthy — more cash than income).

The indirect method starts with net income and adjusts backward to cash. The direct method tallies actual cash receipts and payments. Both arrive at the same OCF. The indirect method is far more common because it reconciles the income statement to the cash flow statement, and most data needed is readily available.
Cash quality = OCF ÷ Net Income. A ratio ≥ 1.0 means the company generates more cash than it reports as profit — generally healthy. A ratio < 1.0 means profits aren't fully backed by cash, which could indicate aggressive revenue recognition, rising receivables, or inventory buildup. Persistent ratios below 0.7 are a red flag.
Non-cash charges like depreciation and amortization reduce net income but don't use cash. A company with $1M net income and $500K depreciation has $1.5M in cash before working capital effects. Additionally, if payables increase (taking longer to pay suppliers) or receivables decrease (collecting faster), more cash is retained.
OCF margin (OCF ÷ Revenue) varies by industry: SaaS 25-40%, manufacturing 10-20%, retail 5-12%, services 15-25%. Higher is better and more stable is especially valuable. Compare against industry peers and track trends over multiple quarters.
Working capital changes often explain the biggest gap between profit and cash. Increasing inventory ties up cash. Rising receivables mean you've recognized revenue but haven't collected. Increasing payables means you delay paying suppliers (preserves cash). Fast-growing companies often consume cash through working capital even while profitable.
OCF shows cash from operations, but businesses must invest to maintain and grow. FCF = OCF − Capex represents cash truly available to shareholders, debt repayment, dividends, or strategic investments. A company with high OCF but equally high mandatory capex has no free cash despite strong operations.
