This cash flow calculator assembles the three-section cash flow statement — operating, investing, financing — and lands on the only line that ultimately matters: ending cash. Enter the period’s flows and it nets them, reconciles against your beginning balance, and flags the pattern your cash is telling you about the business’s life stage.

Three Sections, One Story About Where Cash Lives

The cash flow statement divides a business’s entire cash life into three currents. Operating is the engine: receipts from customers against payments to suppliers, staff, landlords and the tax authority (the direct method, as laid out here — published statements usually use the indirect method, starting from net income and adjusting, which is a different presentation of the same river). Investing is the future being bought or sold: capital expenditures and acquisitions flow out; disposed assets flow in. Financing is the negotiation with capital providers: loans and equity arrive; repayments, dividends and buybacks leave. The three nets must sum, with the beginning balance, to the ending cash — a reconciliation so unforgiving that the statement is considered the hardest of the three financial statements to fake for long, which is precisely why forensic accountants read it first.

The pattern classifier in the results applies the classic life-stage reading: the signs of the three sections (+/−) describe where a company sits. Young growers burn operating cash and live on financing; healthy expanders generate operating cash but invest beyond it; mature compounders generate enough to invest and return capital (our defaults’ pattern: +200k operating, −160k investing, −10k financing → cash up $30k to $150k); companies in decline show operations weakening while asset sales (positive investing) plug the hole — a pattern that can only run until the assets do. No single period convicts or acquits; three periods of the same pattern is a biography.

Worked Example (Verified)

  • The defaults: operating +$200k ($900k in, $700k out), investing −$160k ($180k capex, $20k asset sale), financing −$10k ($50k borrowed, $60k repaid/dividends) → net change +$30k, ending cash $120k → $150k. Cross-check: free cash flow on these numbers is operating − capex = 200 − 180 = +$20k (the FCF Calculator’s stricter question), and the extra +$10k of net change comes from the asset sale net of financing — three statements agreeing with each other is what “the books tie” means.
  • Runway math for the lifeline pattern: operating −$80k/quarter, investing −$20k, financing +$500k raised: the raise covers five quarters of total burn — the sentence every startup board meeting is secretly about, computable from these six fields.
  • The profitable-but-broke period: raise operating outflows to $950k while inflows stay $900k (a receivables pile-up quarter) and operations flip to −$50k despite unchanged sales — the statement shows in one line why growth phases feel cash-poor.

Forecasting With This Statement

As a forecast tool the same skeleton gets honest quickly: project operating inflows with a collection lag on sales (the invoice is not the receipt), outflows on their actual payment calendar (payroll dates, quarterly taxes, annual insurance — lumpiness is realism), investing on the committed capex schedule, financing on the draw/repay plan. The minimum projected ending-cash point across the horizon — not the average — sizes your credit line, because businesses fail at the trough, not at the mean. A rolling 13-week version of exactly this table is the standard instrument of both startup CFOs and turnaround consultants; the granularity changes, the structure doesn’t. And keep the FCF discipline beside it: operating minus maintenance capex is the floor below which “positive operating cash flow” is actually the business eating its own plant.

Frequently Asked Questions

How do you calculate net cash flow?

Add the three section nets: operating (inflows − outflows) + investing (asset-sale inflows − capex/acquisition outflows) + financing (funds raised − repayments and dividends). Our example: +$200k − $160k − $10k = +$30k net change, which added to the $120k beginning balance gives $150k ending cash — the reconciliation every real statement must satisfy. This calculator builds all three sections and the reconciliation from your raw in/out figures.

What are the three sections of a cash flow statement?

Operating activities (the trading engine: customer receipts, supplier and wage payments, interest and taxes under US rules), investing activities (buying and selling long-lived assets and investments), and financing activities (borrowing, repaying, issuing shares, buybacks, dividends). The classification quirks matter: US GAAP puts interest paid in operating; IFRS allows it in financing — one reason cross-border comparisons of “operating cash flow” need a footnote check. The three-section structure itself is universal.

Cash flow vs profit — why do they differ?

Profit is accrual-based: it books sales when invoiced and matches expenses to periods. Cash flow counts only movement. A growing company typically shows profit ahead of cash (receivables and inventory absorb the difference — see the Working Capital Calculator), while a shrinking company can show cash ahead of profit as it liquidates its balance sheet. Over a full business life total profit and total cash converge; within any single year they can point in opposite directions, which is why “profitable but bankrupt” is a real and common obituary.

What is the direct vs indirect method?

Two presentations of the operating section. The direct method (used here) lists gross cash receipts and payments — intuitive, and what managers actually think in. The indirect method starts from net income and adjusts for non-cash items (depreciation added back) and working-capital changes — dominant in published statements because it reconciles profit to cash explicitly, exposing exactly where the accruals went. Both arrive at the identical operating cash flow; a complete indirect statement is a bridge from the income statement, a direct one is a bank statement with categories.

How do I read the signs of the three sections?

As a life-stage fingerprint. (+, −, −) operations funding both investment and capital returns = mature strength (our defaults). (+, −, +) profitable but investing beyond internal generation = growth, funded. (−, −, +) burning cash and raising to cover it = startup or turnaround; runway is the question. (+, +, −) asset sales feeding returns = harvesting or restructuring. Read patterns across three or more periods — one quarter’s signs are weather, three years’ are climate.

What is a 13-week cash flow forecast?

The rolling short-horizon version of this statement, by week, used to manage liquidity through tight periods: each week projects receipts (with realistic collection timing), disbursements on their due dates, capex and financing events, ending in a weekly cash balance whose minimum point is the number that sizes credit lines and triggers decisions. Thirteen weeks is long enough to see the trough and short enough to forecast credibly. The calculator’s structure is the same; only the period granularity and input discipline change.

Does positive net cash flow mean the business is healthy?

Not by itself — the composition decides. Cash rising because financing poured in while operations bleed is borrowed health with an expiry date; cash falling during a deliberate, high-return buildout can be excellent management. The statement’s gift is that it cannot hide which story is true: read operating first (is the engine self-funding?), investing second (is the future being bought or sold?), financing third (who is funding the difference, and on what terms?). This page’s pattern note automates that first reading.
