Working-capital and cash-health analysis
Cash Flow Analyzer
Build a simplified cash-health view from annual P&L amounts, current working-capital balances and the timing assumptions you enter (DSO, DIO, DPO). The live ZenBoxInfinity analyzer returns a Cash Health Score, warnings, strengths and a simplified cash-generation estimate—not a dated bank forecast from individual invoices.
What this page covers
Which inputs the live tool expects, which formulas it applies, how to read the Cash Health Score and CCC, and what the model deliberately leaves out so you do not confuse a simplified estimate with a full liquidity budget.
Scope
What the analyzer evaluates
The Cash Flow Analyzer helps owners and finance teams see how operating profit, net working capital and the cash conversion cycle interact under a growth assumption. It highlights where cash may be tied in receivables and inventory, when growth may require additional working capital, and—when the simplified estimate is negative—an indicative monthly burn and cash runway from available cash.
It does not ingest a schedule of individual customer receipts or supplier payments, and it does not project the bank balance day by day. Timing enters only through the DSO, DIO and DPO values you type.
Audience
Who it is designed for
Owners and GMs
Need a fast read on whether growth and working capital are likely to strain cash under current assumptions.
Finance and controllers
Want a consistent bridge from P&L and WC balances to CCC and a simplified cash-generation lens before deeper forecasting.
Ops and commercial leaders
See how collection, inventory and payables days feed the cash story without rebuilding a full treasury model.
Inputs
Inputs and required data consistency
Use one currency, one comparable accounting basis and one annual period for the financial amounts—the model divides by 365 for daily sales and COGS rates where needed. Enter DSO, DIO and DPO yourself; the tool does not derive them from the general ledger or bank feeds.
Business context
- Industry
- Region
- Revenue Growth Rate (%)
Industry and region adjust internal approximate context thresholds used in scoring and signals—not published market benchmarks.
Annual financial amounts
- Revenue
- Cost of Goods Sold
- Operating Expenses
- Operating Profit — automatic (Revenue − COGS − OpEx) or manual
Cash, WC balances & timing
- Cash; Accounts Receivable; Accounts Payable; Inventory
- DSO; DIO; DPO (days you enter)
Formulas
Confirmed calculations
Gross Profit = Revenue − COGS
When automatic operating profit is on: Operating Profit = Revenue − COGS − Operating Expenses (otherwise the manual operating profit you enter is used).
Net Working Capital = Receivables + Inventory − Payables
Cash Conversion Cycle = DSO + DIO − DPO
Estimated Additional Working-Capital Need = Net Working Capital × Revenue Growth Rate
Simplified Cash-Generation Estimate = Operating Profit − Estimated Additional Working-Capital Need
If that estimate is negative: Monthly Burn Estimate = |estimate| ÷ 12 and Estimated Runway = Available Cash ÷ Monthly Burn Estimate (months).
These last steps are a simplified analytical estimate—not a complete cash-flow statement or a date-accurate bank forecast.
Outputs
Cash Health Score and reported signals
The live tool reports a Cash Health Score—a rule-based indicative score from the figures you entered—plus status/summary text, warnings, strengths, Net Working Capital, Cash Conversion Cycle, cash-flow structure and working-capital views, a CCC display, a cash-flow story, recommendations and print/PDF of the on-screen results when offered.
The score is not a credit rating, not an official industry standard, not an audit opinion and not a bank’s assessment. Industry and regional thresholds inside the model are internal, approximate context parameters only.
Recommendations highlight possible focus areas; they do not guarantee better liquidity.
Profit vs cash
Profit versus cash
Operating profit can look healthy while the simplified cash-generation estimate is weaker if growth implies a larger working-capital load. The analyzer surfaces that gap so profit is not mistaken for free cash under the model’s assumptions. It still ignores many real cash items—tax, interest, principal, capex, dividends and financing—so treat the estimate as a lens, not the bank balance.
Working capital
Working capital and Cash Conversion Cycle
Net Working Capital shows how much capital sits in receivables and inventory after payables. CCC combines the three timing inputs you provide. Stretching CCC or a high NWC relative to revenue can flag cash pressure even when the P&L looks acceptable. Shortening DSO or DIO—or carefully extending DPO—can improve CCC in the model, but operational and supplier realities still govern what is feasible.
Worked example
Hypothetical worked example
Hypothetical illustration aligned with the tool’s demo-style inputs (not a forecast of any real company):
- Revenue 4,800,000; COGS 2,800,000; Operating Expenses 1,200,000; Revenue Growth Rate 18%
- Cash 320,000; Receivables 950,000; Payables 420,000; Inventory 680,000
- DSO 62; DIO 55; DPO 28
- Operating Profit = 4,800,000 − 2,800,000 − 1,200,000 = 800,000
- Net Working Capital = 950,000 + 680,000 − 420,000 = 1,210,000
- Cash Conversion Cycle = 62 + 55 − 28 = 89 days
- Estimated Additional Working-Capital Need = 1,210,000 × 18% = 217,800
- Simplified Cash-Generation Estimate = 800,000 − 217,800 = 582,200
A positive 582,200 does not prove the bank will hold that amount. The model omits many real cash movements; it shows how growth and capital tied in receivables and inventory can change the operating-cash picture under these assumptions.
Reading results
How to interpret warnings and strengths
- Warnings often point to stretched CCC, growth absorbing working capital, thin cash buffers or profit that does not translate into the simplified cash estimate.
- Strengths may reflect healthier cycles or stronger buffers relative to the model’s internal thresholds.
- Runway and monthly burn appear when the simplified estimate is negative—use them as directional coverage math, not a commitment calendar.
Limits
What the analyzer does not forecast
- No bank or accounting-system connection.
- No invoice-level due dates or payment schedules.
- No daily or monthly receipt/disbursement calendar.
- No full capex plan; no automatic interest, tax, principal, dividends or financing layers.
- Not a substitute for a cash-flow statement, liquidity budget or professional financial analysis.
- Does not guarantee future liquidity.
Mistakes
Common input mistakes
- Mixing currencies or periods across Revenue, COGS and OpEx.
- Entering monthly amounts where the model expects annual figures.
- Leaving DSO/DIO/DPO as guesses disconnected from how you actually collect, stock and pay.
- Turning off automatic operating profit without aligning the manual figure to the same period.
- Reading the simplified cash-generation estimate as a promised bank balance.
- Treating the Cash Health Score as a credit score or lender decision.
Workflow
Practical review workflow
- Assemble annual P&L amounts and current cash/WC balances in one currency.
- Set Industry, Region and a realistic Revenue Growth Rate.
- Enter DSO, DIO and DPO from your operating reality.
- Run the analyzer; note score, NWC, CCC and the simplified cash estimate.
- If burn/runway appear, treat them as coverage under these assumptions only.
- Decide which operational levers (collections, inventory, payables, growth funding) need a deeper plan outside the tool.
- Print or save results if offered, then refresh inputs when the business changes.
FAQ
Common questions
Does the analyzer forecast my bank balance by date?
No. It uses annual amounts, WC balances and the DSO/DIO/DPO you enter—not individual payment timing.
Are DSO, DIO and DPO calculated automatically?
No. You enter them. The tool uses them to form CCC and related signals.
What is the simplified cash-generation estimate?
Operating Profit minus estimated additional working-capital need from NWC × growth rate. It is analytical, not a full cash-flow statement.
When do burn and runway appear?
When that simplified estimate is negative: monthly burn is the absolute estimate ÷ 12; runway is cash ÷ monthly burn.
Is the Cash Health Score official?
No. It is a rule-based indicative score from your inputs and internal model thresholds.
Should amounts be annual?
Yes. Enter annual financial amounts for a consistent period; the model uses a 365-day basis in related rates.

Using the Cash Flow Analyzer in practice
The Cash Flow Analyzer helps finance leads map operating inflows and outflows without waiting for month-end close. Teams use it when receivables stretch, supplier terms tighten, or a new product line changes working-capital needs. Start with actual bank movements and open AR/AP balances rather than accrual estimates so the output reflects liquidity you can act on this week.
